Introduction
Why acquisition in financial services is a unit-economics problem
A financial product does not pay back on clicks. It pays back on the margin earned across the period a customer holds it, against what it cost to acquire them. Every institution we have worked with, from a mutual bank to a global trading platform, has had to be persuaded to measure acquisition that way. This guide is the method, in the order it has worked.
The six things that make it hard
Financial services acquisition runs into the same six obstacles whatever the product. They are worth naming, because each chapter in this guide is a response to one of them.
- The buyer is comparing on price, in public. A term deposit, a home loan, a credit card or a brokerage account is shopped on a comparison site before your page is ever opened. If your rate is not competitive, no campaign fixes that. If it is, the campaign has to prove it at the moment of decision.
- The category is dominated by balance sheets bigger than yours. The Big Four in Australia, the high-street banks in the United Kingdom and the captive lenders at the dealership advertise nationally, at category-typical cost, all year. A mutual or a specialist cannot outspend them; it has to out-target them.
- The conversion happens after the click, and often after a human. A home loan application becomes a loan at the landing page and the broker handover, weeks later. A trading account is worthless until it is funded. Attribution that stops at the form is attribution of the wrong event.
- The margins are thin and regulated. Interchange on a low-rate card is capped. Net interest margin in the mutual sector runs near two percent. Acquisition cost has to sit inside those numbers, which means the ceiling is set by the product, not by the media plan.
- The rules are real, and they reach the ad. An Australian credit ad needs a comparison rate. A UK financial promotion has to be clear, fair and not misleading, and since 2023 has to show it delivers good outcomes. A New Zealand lender advertises inside the Responsible Lending Code. Every page, ad and email is written inside those lines.
- Trust is the product. A mutual’s community standing, a bank’s award, a platform’s regulator licence: these are the reasons a rate-shopper chooses you over the cheapest listing. They only work if the customer can see and verify them at the moment they decide.
Why it is worth doing on the numbers
When the economics are modelled properly, financial services rewards acquisition more than almost any other category, because the customer keeps paying. A term deposit acquired for Teachers Mutual Bank was worth the margin on its balance for the three years it was held, not the cost of the click that opened it. Modelled at the mutual sector net interest margin KPMG disclosed for the period, 2.03%, and a three-year average holding period, a single six-week campaign returned 5,090% on its investment. The acquisition cost was paid once; the margin was earned for three years.

What follows is the order we now build it: the website first, then organic and AI search, then paid search by product line, then the audiences, the amplification, the conversion flow, the nurturing that turns an application into money, and the attribution and economics that decide what to do next. Chapter one starts with a trading platform whose acquisition problem turned out to be its website.
Chapter 1
The website is the first credit decision
Before a prospect applies for anything, your website has already decided whether they will. It is read by a rate-shopper on a train, by Google’s crawler, by the comparison engines that scrape it and by the AI assistants that now answer “which bank should I use for this”. It has to work for all of them.
A trading platform that started with the site
Rakuten Securities, a global forex and metals trading platform, came to us with a media problem: sign-ups were expensive, and the sign-ups that arrived were not funding their accounts. The previous programme had been run by the group’s own marketing arm. The instinct was to fix the ads. The first thing we did instead was rebuild the website.
The site was redesigned and built from the ground up, every piece of creative with it, and the acquisition was restructured as a two-stage funnel: acquire the sign-up first, fund the account second, with each stage measured on its own. Campaigns were written for people who already understood the vocabulary of the product, so the site had to speak the same way. Only then did the media change: long-tail search terms instead of broad ones, audiences cut into micro-niches by interest, platform, intent stage and geography, and continuous creative testing across every format.
What a financial services website has to do
- One page per product, with the rate and the fee on it. A page called “Savings” competes with every bank on earth. A page called “Term deposits for self-managed super funds”, with the current rate, the minimum balance and the term options in the first screen, competes with almost nobody and answers the question the searcher typed.
- The number the law requires, where the law requires it. In Australia a consumer credit rate is advertised with its comparison rate and the prescribed warning. In the United Kingdom a credit promotion carries a representative APR. Put them where a regulator would look for them, and where a customer would, which is the same place.
- Calculators and eligibility before the application. A repayment calculator, a borrowing-power estimate, a deposit-growth illustration. They do two jobs: they keep the ineligible from applying and wasting your assessor’s time, and they let the eligible see the number before they commit.
- An application in as few steps as the risk allows. Identity and consent checks belong late in the flow, not on the first screen. Save-and-resume is not a luxury on a home loan form; it is where a third of your applications would otherwise die.
- The people and the licence. Australian financial services licence and Australian credit licence numbers, the FCA firm reference, the FMA register entry. Names and photographs of the people who answer the phone. Anonymous institutions are hard to trust and, as chapter two explains, hard for an answer engine to recommend.
- The proof. Awards, audited growth, member numbers, the years in business. Teachers Mutual Bank’s credit card carried Money Magazine’s Cheapest Credit Cards recognition through its campaign window, and that third-party line did more at the moment of decision than any headline we wrote.
Speed is a ranking factor and a trust factor
Google measures how real visitors experience your site and uses it in ranking. The three Core Web Vitals are Largest Contentful Paint (the main content should appear within 2.5 seconds), Interaction to Next Paint (the page should respond to a tap within 200 milliseconds) and Cumulative Layout Shift (nothing should jump around after it loads; a score under 0.1). Most institutional sites we audit fail the first one on a phone, because a content platform and a tag manager ship a megabyte of scripts before a rate is visible.
The commercial cost is simpler than the technical one. A rate-shopper on a train opens two lenders from a comparison site. One paints in a second, the other in six. The second lender does not get a second chance, and never finds out. Our free website audit measures six things on any site, from the bytes it actually sends rather than from a score: whether the final URL is secure, whether the homepage title says what the institution does, whether anything on the page tells Google where it is, whether the page tells a phone how to size itself, whether there is a description for search results to show, and how heavy the document and its render-blocking assets are.
Writing inside the rules
Compliance is not a reason to say less; it is a reason to say precise things. In Australia, ASIC’s Regulatory Guide 234 sets out what good advertising of financial products looks like, the National Credit Code requires a comparison rate whenever a consumer credit rate is advertised, a general advice warning is required where the content could be taken as advice, the design and distribution obligations mean every product has a target market determination the marketing has to respect, and a licensee that earns commission cannot call itself independent. In the United Kingdom, every financial promotion has to be clear, fair and not misleading under the FCA’s rules for investments, consumer credit and mortgages, and the Consumer Duty in force since July 2023 asks the firm to show the promotion supports good outcomes, not merely that it avoided bad ones. In New Zealand, the Financial Markets Conduct Act’s fair dealing provisions cover every financial product, and consumer credit is advertised inside the Credit Contracts and Consumer Finance Act and the Responsible Lending Code.
The practical version: state the rate, the fee, the eligibility and the audience the product was designed for, in the words the regulator uses. Use customer outcomes with permission and with the caveats the licence requires. Have your compliance team read the site once, and keep a note of what they approved. Then never write a page, an ad or an email that could not pass the same reading.
Chapter 2
Organic search and the AI engines
The comparison sites own the head terms and the AI assistants quote them. An institution cannot win “best term deposit rates” organically this year. It can win the long tail where its product actually fits, and it can make itself the entity the answer engines are able to name.
Where the rate-shopper starts
The queries in financial services sort into three kinds. Head terms (“home loan rates”, “best savings account”) are held by comparison sites, the largest banks and, increasingly, by an AI Overview that summarises the comparison sites. Product-and-segment terms (“term deposit rates for SMSF”, “home loan for teachers”, “low rate credit card no annual fee”) are where a mutual or a specialist can rank, because the page that answers them is specific and the competition is thin. Question terms (“fixed or variable in a falling rate environment”, “what does a mortgage broker cost”) are where the AI engines do most of their answering, and where an institution earns the trust the product pages convert.
The plan for organic search is therefore not to chase the head. It is to build one page for every product-and-segment query you can honestly serve, one guide for every question that comes before the purchase, and the entity signals that let a machine say your name with confidence.
Pages that earn the click
- Product pages that answer, in order. The rate and the fee, who it is for, what it costs to leave, how to apply, and the four questions people actually ask. The answer to each question in one plain paragraph under its own heading, so a search engine and an assistant can lift it whole.
- Guides for the question before the purchase. Fixed versus variable. Offset versus redraw. What funding a trading account involves. Whether a roboadvisor is advice. Owners Advisory by Macquarie’s programme treated category education as the precondition to acquisition for an emerging product, and doubled the site’s traffic in four months doing it.
- Calculators that are pages. A repayment calculator with its own URL, its own title and its own explanation ranks for “repayment calculator” queries and hands a warm visitor to the product page beside it.
- The member story. A mutual’s reason to exist is its members. Teachers Mutual Bank’s deposit growth of 16.3% against a sector rate of 10.5% is a story about who the bank is for, and it belongs on the site in plain numbers.
Being the answer, not just a result
An answer engine, whether Google’s AI Overview, ChatGPT, Gemini or Perplexity, names an institution when it can corroborate it: the same name, product and claims across the regulator’s register, the comparison sites, the awards, the reviews and the institution’s own site. For financial products the engines lean unusually hard on those external sources, because the cost of being wrong is high. That makes the work concrete. Every listing has to carry the same legal name, the same licence number and the same product names. Every award has to be visible on the site and on the awarding body’s site. Every person named on the site has to be findable on a professional network.
On the page itself, the answer-engine work is a direct answer at the top of every product and guide page (two or three sentences that state the fact, the number and the condition), question-and-answer sections marked up as FAQ structured data, organisation and product structured data that carries the licence, and named authors with their own profile pages. A page that ranks on the first page of classic results and carries none of this is invisible to the part of search that is growing.
Chapter 3
Paid search: buy the rate-shopper at the moment of decision
Google Ads is where financial services acquisition is won or wasted, because the moment someone types a product and a rate is the moment they decide. The Big Four buy that moment at category-typical cost. A mutual or a specialist buys it more precisely, and the four Teachers Mutual Bank product lines are the record of how.
State by state, brand from generic
The home loan programme ran three connected flights across the portfolio: the largest, multi-channel Australian Dream flight; a Classic Home Loans flight weighted toward retargeting; and a tightly bounded six-week Fixed Home Loans flight at a prime rate. The search architecture was the same each time. Every state and territory was campaigned separately, with brand and generic keyword sets split in each, so a searcher in Perth saw copy and bids set for Western Australia rather than a national average. The acquisition cost had to stay materially under A$1,000 per application for the unit economics to hold.
Across the three flights the search and social system produced 103,211 clicks, 33.5 million impressions and 342 verified home loan applications at a blended A$716 per application. The Fixed Home Loans flight recorded a 22.17% Google Search click-through rate over 33,009 impressions, 7.6 times the Finance and Insurance Search benchmark of 2.91%; Australian Dream ran at 16.37% over 232,153 search impressions. At the bank’s documented 66% application-to-loan conversion that is roughly 226 settled loans and, at the documented average new loan size in the window, approximately A$94 million in modelled originations.

Where the product’s price is the ad
The credit card product was deliberately low-rate, which constrained its economics: less revolver interest, more reliance on interchange, which is capped under the Reserve Bank’s standard. Acquisition cost had to sit far below the category. The search layer targeted low-rate and balance-transfer keyword sets where the product’s actual price advantage could win the click, with comparison-channel placements used selectively and a Facebook prospecting layer in the education-sector audience. Applications were acquired at approximately A$12 each against an approximate A$110 Finance and Insurance Search benchmark: 777% below it. The Money Magazine Cheapest Credit Cards recognition the product held through the window corroborated the price story at the moment of decision. A competitive price, a keyword set concentrated on the intent that price wins, and a landing page that did not leak: the gap came from all three together.
Consumer-direct, before the showroom
Car loans are captured at the point of sale by dealer finance and nationally by the largest banks. A mutual wins the consumer-direct segment instead: the buyer who has chosen the car and is shopping the loan, before the dealer’s finance partner meets them at the showroom. A six-week consumer-direct flight routed straight to the product page delivered 5,975,708 impressions, 13,038 clicks at A$2.94 and 66 verified applications at A$566.96 each. At an industry-typical 66% application-to-settlement conversion that is about 44 settled loans and, at the Australian Bureau of Statistics average new car loan of about A$24,000, approximately A$1.05 million in modelled lending, a modelled multi-year margin return of about 239% with a sensitivity band the case study states rather than hides.
Rules of the account
- Phrase and exact match only, negatives first. Broad match on “home loan” buys the entire mortgage-broker industry’s curiosity. The search-terms report is read weekly and every term you would not pay for becomes a negative before it costs another click.
- One landing page per ad group. The low-rate card ad lands on the low-rate card page with the rate in the first screen, not on the credit cards hub.
- Brand campaigns kept separate. Brand traffic converts at a rate that flatters everything it is mixed with. Report it alone so the generic campaigns are judged on their own economics.
- The legal number in the ad. A comparison rate in an Australian credit ad, a representative APR in a UK one. Ads that omit them are disapproved late and expensively.
- Manual bids until the account can learn. Smart bidding needs volume; a mutual’s ad group does not have it on day one. Manual cost-per-click caps for the first thirty days, then a target cost per application once an ad group has thirty conversions to learn from.
- The conversion is the application, and later the settlement. Never the click, never the calculator use. Chapter eight covers how the settled loan gets back into the account.
| Product line | The buyer | The keyword set | The number |
|---|---|---|---|
| Term deposits | The rate-shopper, the maturing member, the community prospect | Comparison, rollover and brand-defensive sets | 5,090% return on a single flight |
| Home loans | Variable, fixed and refinance borrowers, state by state | Brand and generic split per state and territory | A$716 per application; A$94M modelled originations |
| Credit cards | The cost-conscious comparison shopper | Low-rate and balance-transfer intent | About A$12 per application, 777% below benchmark |
| Car loans | The consumer-direct buyer who has chosen the car | Loan-rate intent, routed to the product page | A$566.96 per application; A$1.05M modelled lending |
Chapter 4
Attracting the right customers
The cheapest application is worthless if the applicant is ineligible, and the most expensive one is cheap if it funds and stays. Attracting the right customers is an audience problem before it is a media problem, and the products that worked best were the ones where the audience was cut three ways before a dollar was spent.
Three audiences, one product
The term deposit campaign ran three parallel audience strategies, each with its own creative, intent profile and channel allocation. The comparison shopper, actively rate-hunting, was captured on Google Search. The existing member with a deposit maturing was reached through a rollover set and remarketing. The community-trust prospect, the teachers and education-sector audience the bank exists for, was reached through Facebook prospecting on the mutual’s own story rather than on rate. Working media ran at a blended A$2.43 per click and scaled materially through the engagement as performance gave the business case to keep investing.
- 24,722Estimated monthly prospecting clicks across Google Ads, Facebook, programmatic display and Instagram at a blended A$2.43 per clickCase study →
- 5,556Estimated monthly remarketing clicks against recent site visitors on Facebook and the Google Display NetworkCase study →
- 2,847Estimated monthly closing clicks against the abandoned application audienceCase study →
The three-stage shape, prospect, remarket, close, is the one to copy. Each stage has a different audience, a different message and a different acceptable cost, and reporting them together hides which one is working.
Micro-segmentation for a trading audience
For Rakuten Securities the audiences were cut into micro-niches by interest, trading platform, intent stage and geography, then targeted across Google, Facebook, YouTube, LinkedIn, Twitter and programmatic. Creative was written for people who knew what tight spreads and leverage meant, because those were the people who funded accounts. Google’s strategy moved from broad targeting to long-tail and competitor terms; on the Chinese-language variants in Australia, cost per click fell 42%. Facebook conversion rates rose 3.4 times after the audiences were refined. The lesson is not the platforms; it is that the segmentation was done on who funds, not on who clicks.
Timing the market
JB Markets, a securities and derivatives firm serving wholesale and retail traders, needed net new trader sign-ups at a cost per lead under A$50. Two gated offers ran in parallel: an ASX report delivered both through a landing page and through Facebook lead ads, with the two funnels tested against each other; and a Bitcoin Futures campaign timed to the CME’s launch of the contract, when news coverage and visible price action were drawing prospective traders to the category. Leads arrived at A$40 in the first week, A$10 under target, and at A$20 once the testing data accumulated. A timely offer with a real hook, aimed at the buyer the firm could actually serve, halved the cost the plan had budgeted.
Who not to attract
Every product has a target market determination or its equivalent, and it is the most useful audience brief in the building. The speculator who will never fund, the rate-hopper who leaves at the first maturity, the applicant outside the lending criteria: each costs an assessment and returns nothing. Exclude them in the targeting, say who the product is for on the page, and ask the qualifying question before the application, not after it.
Chapter 5
Amplifying reach: social, programmatic and the premium environment
Search captures the decision. The channels around it decide how many people reach that moment already knowing your name, and, when the attribution is honest, they carry a share of the conversions that search is usually credited with.
Paid social carries weight when it is attributed
On the home loan programme, Facebook prospecting against custom audiences produced 95 home loan conversions at A$384 each, outperforming search on both volume and cost on the same flight. AdRoll retargeting across the long consideration window produced 85 at A$528. Neither number would have been visible on last-click reporting; both were visible because the attribution had been rebuilt on Campaign Manager 360 before the first flight. Social and retargeting are not awareness spend in financial services. They are acquisition channels that happen to sit earlier in the visit.

Premium environments without premium cost
For the launch of Apple Pay, Macquarie Bank’s display campaign was constrained to an Apple-mandated list of 48 premium publications, from the BBC and the Sydney Morning Herald to Forbes, Reuters and The Economist. Inventory like that usually carries a cost per thousand many multiples above the open market. The placement strategy concentrated spend on the publications where the bank’s audience was already present rather than spreading across the whole list, and the static brand assets were animated into HTML5 creative fit for those environments. The campaign delivered at a cost per thousand of A$2.52 and a cost per click of A$3.14. Brand-environment discipline, built into the workflow rather than bolted on, absorbed the constraint without inflating the cost.
Traditional and digital in concert
Owners Advisory by Macquarie was a newly launched roboadvisor for do-it-yourself and self-managed super fund investors, in a category the market did not yet understand. The programme ran traditional media alongside performance digital under one team, on the premise that for an emerging product buyer education is the precondition to acquisition. Search, social and display carried the high-intent capture; traditional media carried the category. Sessions rose from 4,453 a month at kickoff to a peak of 9,703, a 2.18 times lift, with users up 2.76 times, and held at 8,726 in month four. For a product nobody was searching for by name, the awareness layer compounding into engaged sessions was the number that mattered.
Chapter 6
Converting visitors into applications
In financial services the landing page and the application are the same thing, and the application is where the money is lost. The credit card programme’s gap to benchmark came from a page that did not leak as much as from the keyword set that filled it.
The application is the landing page
- The rate, the fee and the next step in the first screen. A visitor from a comparison site is checking that the page says what the listing said. If it does not, they are gone before the scroll.
- Eligibility before effort. Two questions that tell the ineligible not to bother save your assessors a queue and save the applicant a rejection.
- Steps sized to the product. A term deposit can open in five minutes. A home loan application is a conversation across days; build save-and-resume and a named human into it.
- Identity and consent late, not first. Verification belongs after the applicant has decided, not as the price of finding out.
- The disclosure block where the regulator would look. Comparison rate, target market, general advice warning, licence numbers. Present, legible, and not in the way.
- A human option on every screen. A phone number that is answered and a booking link. The applicant who would rather talk is often the one with the largest balance.
Lead form or landing page? Test it
JB Markets’ gated ASX report was delivered two ways at once, through a landing-page form and through Facebook’s native lead form, and the two were tested against each other as the campaign accumulated data. That test is what moved cost per lead from A$40 in week one to A$20. Native lead forms convert more cheaply and qualify less; landing pages convert fewer people and tell you more about them. Which one wins depends on what your sales team does with a lead next, so run both and let the funded-account number decide.
Funded, not just signed up
The Rakuten Securities restructure split acquisition into two stages with two measurements: the sign-up and the funded account. Sixty percent of sign-ups funded, which is the number the business case was built on, and it was only knowable because the second stage was instrumented separately. A brokerage, a lender or a bank has the same second stage under a different name: funded, settled, activated, first deposit. Name it, measure it, and report conversion against it rather than against the form.
Chapter 7
Nurturing through funding and settlement
Between the application and the money there is a gap, and the gap is where a third of your acquisition cost is quietly wasted. The home loan programme’s 66% application-to-loan conversion was a documented rate, not an assumption, and everything in this chapter exists to move a number like it.
The gap between application and money
On the home loan flights, one application in three did not become a loan. On the car loan flight the same industry-typical rate applied. On the trading platform, four sign-ups in ten did not fund. The reasons repeat: documents not supplied, a competing offer, a broker who went quiet, a buyer captured at the showroom, an applicant who simply forgot. None of these is a media problem, and no amount of media spend fixes them. A nurturing sequence does, and it is the cheapest conversion lift in the funnel because the acquisition cost has already been paid.
Sequences that stay inside the rules
- Service messages, not promotions, wherever the law allows it. “Your application is missing a payslip” is a service message. “Rates have moved, apply now” is a marketing one, and it needs consent under the Spam Act in Australia, the Unsolicited Electronic Messages Act in New Zealand and the privacy and electronic communications rules in the United Kingdom.
- Short, specific, and stopped when the job is done. Three touches over ten days for a deposit; a longer, gentler cadence for a home loan that is waiting on a valuation. Every message answers one question or asks for one thing.
- A named person. The sequence comes from the lending specialist or the account manager, with a direct number, not from a no-reply address.
- The same compliance reading as the site. The comparison rate, the target market and the general advice warning travel with the message.
Capacity is part of the funnel
JB Markets’ campaign had to be paused. Not because it failed, but because at A$20 a lead it produced more volume than the internal sales team could service, and a lead that waits is a lead that goes elsewhere. The pause held until the firm streamlined its process to absorb what the campaign could deliver. Plan the handover before the first flight: how many qualified applications a week the team can process, who owns the ones that arrive on a Friday afternoon, and what the campaign does when the queue is full. A budget the operation cannot absorb is not a growth plan.
The rollover audience
The cheapest deposit a bank acquires is the one it already holds. The term deposit system’s existing-member rollover set, reached through remarketing and the member channel at maturity, was one of its three audiences for a reason: the acquisition cost is near zero and the balance is known. Every product has an equivalent moment, the fixed rate expiring, the card anniversary, the account that has not traded in ninety days. Build the sequence for it before you buy a single new customer.
Chapter 8
Tracking and attribution
Every Teachers Mutual Bank product line ran on the same attribution architecture, rebuilt in Campaign Manager 360 before the first flight, and that one decision is why the numbers in this guide exist at all. Attribution comes before spend, because spend without it is opinion.
Rebuild the attribution before the first flight
The home loan, term deposit, credit card and car loan systems shared one attribution layer, so every channel’s contribution to every product could be reconciled and the channel mix reset between flights on what had actually worked rather than what was assumed to have worked. It is the reason Facebook’s 95 home loan conversions and retargeting’s 85 were counted instead of credited to the last search click, and it is the reason the next year’s plan could be modelled rather than guessed. The rebuild is unglamorous work: a tag plan, a conversion taxonomy, consented cookies, server-side events where the browser blocks them, and a reconciliation against the core banking system every month.
Define the conversion by the product
| Product | The platform sees | The business counts | How it gets back |
|---|---|---|---|
| Term deposit | Application submitted | Balance funded, with its size and term | Offline import of funded balances, weekly |
| Home loan | Application submitted | Loan settled, with its principal | Offline import at settlement; broker outcomes reconciled monthly |
| Credit card | Application submitted | Account approved and activated | Offline import at activation |
| Trading account | Sign-up | Account funded, with its first deposit | Server event on first deposit, matched to the click id |
| Wealth and advice | Engaged session or enquiry | Qualified lead, then client | CRM stage changes imported as conversions |
The platform is told about the second column and optimises for it. The business is run on the third. Chapter eight’s job is to make the fourth column real, so the platform learns from the number that matters.
Close the loop offline
Google Ads and the social platforms accept conversions after the fact, matched by the click identifier stored at the first visit. A settled loan imported three weeks after the click teaches the bidding which keywords produce loans rather than applications, and it is the single biggest lever on cost per funded customer once the account has volume. Consent comes first: the click identifier is personal data under the Privacy Act in Australia, the Privacy Act 2020 in New Zealand and the UK GDPR, so the consent banner, the privacy policy and the data-sharing terms have to say what is being done with it.
The five numbers to report monthly
- Cost per application, by product line and by channel, with brand reported separately.
- Application-to-funded (or settled, or activated) rate, and the days it takes.
- Cost per funded customer, the number the ceiling in chapter nine is set against.
- Modelled margin acquired this month, on the product’s own economics, with the assumptions stated.
- Share of conversions attributed beyond last click, so the channels that start the journey are funded as well as the one that ends it.
Chapter 9
The economics: margin, ceilings and modelled returns
The question is never “what is a good cost per lead”. It is “what is an acquired customer worth over the period we hold them, and what fraction of that can we spend to acquire them”. The four models below are the case studies’ own models restated, with their assumptions and their sensitivity, so you can rebuild them for your products.
Set the ceiling from the margin, not the market
The ceiling on acquisition cost is the modelled margin per customer, multiplied by the holding period, divided by the payback you require. For a term deposit: the average balance acquired, times the net interest margin, times the average years held. Teachers Mutual Bank’s campaign modelled the balances at the KPMG-disclosed mutual sector margin of 2.03% over a three-year average hold, which produced A$5.7 million of modelled margin from a single six-week flight and a 5,090% return on the campaign investment. The same arithmetic, run before the campaign, is what set the cost the campaign was allowed to pay.
Worked models from the case studies
| Product | Acquisition | Conversion to money | Value basis | Modelled result |
|---|---|---|---|---|
| Term deposits | One six-week flight at a blended A$2.43 per click | Balances funded | 2.03% sector margin over a three-year hold | A$5.7M margin; 5,090% return |
| Home loans | 342 applications at A$716 each | 66% documented application-to-loan; about 226 loans | Documented average new loan size in the window | About A$94M originated |
| Car loans | 66 applications at A$566.96 each | 66% industry-typical; about 44 loans | ABS average new car loan of about A$24,000 | About A$1.05M principal; 239% modelled margin return |
| Credit cards | About A$12 per application | Approved and activated accounts | Interchange-led, capped, so the ceiling is low | 777% below the A$110 category benchmark |
Sensitivity, honestly
A model is only as useful as the range it admits. The car loan return of about 239% carries a stated band of 107% to 389%, reflecting the ABS principal range of A$22,000 to A$26,000 and a net-margin band of 8% to 16%. The home loan originations depend on the documented 66% conversion holding. The deposit margin depends on balances staying for three years. State the bands, update them from the settled numbers every quarter, and let the ceiling move with them. A return quoted without its assumptions is a number nobody should spend against.
Growth you can audit
The test of a modelled return is whether it shows up in the accounts. In the engagement period, Teachers Mutual Bank’s audited retail deposit book grew A$743 million, from A$4.55 billion to A$5.29 billion, a 16.3% increase against a mutual sector rate of 10.5%. The home loan portfolio grew 20.6% to A$5.2 billion, more than twice the sector’s residential lending growth of 9.8%. The asset base grew from A$5.54 billion to A$6.68 billion. The acquisition systems were one contributor among several, and the case studies say so; the point is that the campaign models and the audited growth pointed the same way.
Conclusion
The order of operations
None of this is complicated. Most of it is unfashionable, because the fashionable part, the media, comes fifth. Done in this order, each step makes the next one cheaper.
What to do, in order
- Model the customer’s value first. Margin, holding period, payback. Set the ceiling on acquisition cost from that, per product line, and write it down.
- Rebuild the attribution. One layer across every product and channel, the conversion defined as the money event, the loop closed offline with consent.
- Fix the website. One page per product with the rate on it, calculators and eligibility before the application, speed on a phone, the licence and the people, the disclosures where they belong.
- Earn the long tail and the answer. Product-and-segment pages, the guides for the question before the purchase, and the entity work that lets an assistant say your name.
- Buy the decision precisely. Phrase and exact match, state by state, brand apart from generic, one page per ad group, manual bids until the account can learn.
- Cut the audiences three ways and amplify. Prospect, remarket, close; social and retargeting funded on attributed conversions; premium environments bought with discipline.
- Convert to the money event, then nurture to it. Applications that do not leak, a test between forms, a sequence inside the rules, a team sized to the volume.
- Report five numbers, and move the ceiling with the settled results.
The engagements in this guide were run for institutions that measured acquisition on their own economics and had the patience to build in this order. If you would like to see what the same order would look like for your products, the fastest way is a short call with the person who wrote it.
This quarter
Six things to do before you spend a dollar.
- 01Write down, for each product line, what an acquired customer is worth over the period you actually hold them: the modelled margin, not the first year’s revenue. Every budget decision in this guide is made against that number.
- 02Open your best product page on a phone over mobile data and time it. If the rate, the fee and the next step are not on the first screen, that is the first job.
- 03Search your product with your state or city attached, in a private window. Note which comparison sites, which competitors and which awards the AI answer names. If your institution is absent, chapter two explains why.
- 04Pull the search-terms report from your Google Ads account for the last ninety days. Highlight every term you would not want to pay for. That is your negative list and the case for phrase and exact match.
- 05Ask your CRM one question: of the last hundred applications, how many funded or settled, and how long did it take? If it cannot answer, attribution comes before spend.
- 06Ask your sales or lending team how many qualified applications a week they can actually process. If a campaign could exceed that, plan the handover before the first flight.
