Google Ads for Mortgage Brokers: A Compliance-Safe Playbook

18 August 2026·6 min read

Quick answer: Google Ads works for mortgage brokers when campaigns are structured by loan type (first home buyer, refinance, investment, self-employed), ad copy never promises a rate or guarantees approval, and a solid negative keyword list is filtering out job seekers and DIY researchers from day one. Below is the exact campaign structure, a compliant ad copy formula you can steal, and a starter negative keyword list to paste straight into your account. 📈

Most brokers who've tried Google Ads and given up didn't have a compliance problem — they had a structure problem. One campaign, one ad group, every keyword from "home loan" to "best mortgage rate" thrown in together, and an ad that says "Get Approved Fast!" Six weeks later the budget's gone, three leads were job seekers, and the broker decides ads "don't work for brokers." They do. You just need the boring structural stuff sorted before you touch the ad copy — and honestly, that boring stuff is where the trust (and the compliance risk) actually lives. 💖

What most mortgage brokers get wrong with Google Ads

Running one campaign for every loan type — a first home buyer and a self-employed investor search completely differently, and Google can't optimise bids well for both inside the same ad group.
Writing ad copy that sounds like a guarantee — "Get approved in 24 hours" or "Best rates guaranteed" isn't just risky under NCCP, it also tends to get rejected or throttled by Google's financial services ad policies.
Skipping negative keywords entirely — without them you're paying for clicks from people searching "mortgage broker jobs," "how does a mortgage work," and "mortgage calculator free" who were never going to call.
Sending every click to the homepage — a first-home-buyer searcher landing on a generic "About Us" page bounces, because nothing on the page answers the specific question they typed.
Setting and forgetting — no one's checking the search terms report weekly, so the account slowly fills with irrelevant clicks nobody's excluding.

Copy-paste starter kit: campaign structure, ad formula and negative keywords

1. Campaign structure by loan type (one tightly themed ad group each):

First home buyer — "first home buyer loan [region]", "FHB grant broker", "how much can I borrow first home"
Refinance — "refinance home loan [region]", "switch mortgage broker", "refinance to lower repayments"
Investment — "investment property loan broker", "interest only investment loan [region]"
Self-employed — "self employed home loan broker", "low doc home loan [region]", "ABN home loan"

2. Compliant ad copy formula — plug your details in, nothing else:

Headline 1: [Loan type] Broker – [Region]
Headline 2: [Number] Lenders Compared For You
Headline 3: Book a Free Chat, No Obligation
Description: We compare [number]+ lenders to find options that suit your situation. [Years/credential] experience. Enquire online or call [phone].

Avoid: "guaranteed," "approved fast," "best rate," "lowest rate," or any specific interest rate or approval timeframe stated as a promise.

3. Starter negative keyword list (paste at account level):

free, jobs, career, salary, calculator, template, course, university, definition, "how does", DIY, PDF, "no broker", forum, reddit, complaint

First-home-buyer-focused broker: Ran one campaign split into four suburb-based ad groups across the Gold Coast, headline "First Home Buyer Broker – Gold Coast," description mentioning lender count and a free 20-minute chat. Added 38 negative keywords in week one, including "grant amount" and "eligibility calculator." Cost per lead dropped from $94 to $41 in six weeks — not because the ads got cleverer, but because the account stopped paying for people who wanted a calculator, not a broker.

Self-employed specialist broker: Built a dedicated "self-employed / low-doc" campaign targeting "self employed home loan broker" and "ABN home loan no payslips," landing every click on a page that explained the low-doc process step by step instead of the homepage. Conversion rate on that landing page ran roughly triple the site average, because the page answered the anxious question in the search term instead of making the visitor go hunting for it.

Refinance-focused broker: Excluded "refinance calculator," "how to refinance," and "refinance vs redraw" as negatives from day one — those are research-stage searches, not ready-to-call searches. Ad copy stuck to "Refinance Review – Compare [X] Lenders, No Cost To You" rather than naming a rate or saving figure. Leads were fewer in volume but far more likely to book a call, because the searchers who clicked through were already past the research stage.

How the structure actually protects your compliance and your budget

Google Ads for financial services sits under two layers of scrutiny at once: Google's own financial services ad policies, and the NCCP/ASIC expectations you already carry around not overstating outcomes. Splitting campaigns by loan type lifts your Quality Score because ad relevance to each keyword actually improves — Google rewards specificity. Negative keywords stop budget disappearing on inappropriate clicks like job seekers. And a loan-type-specific landing page does double duty: it converts better and it demonstrates you're giving relevant, accurate information rather than a generic pitch dressed up for every search term. None of this replaces your compliance process — it just means your ads are built on the same honesty your file notes already require.

💡 Heads up: Google's financial services ad policies require certain certification checks for Australian credit licensees — if your ads keep getting disapproved for no obvious reason, check your Google Ads financial services status before rewriting the copy again.

Mistakes that quietly burn your ad budget

Using broad match on every keyword — without phrase or exact match mixed in, a broad match "home loan" keyword will match on almost anything loosely related.
Never checking the search terms report — this is the single highest-leverage ten minutes a week you can spend on an ads account.
Promising speed you can't control — lender turnaround times are outside your control, so "approved in 24 hours" is a claim you can't actually stand behind.
Ignoring call extensions — most loan searches happen on a phone, so skipping a "call now" extension skips the easiest conversion path.
Running ads to a page with no clear next step — if the landing page doesn't have one obvious call to action, the click is wasted regardless of how good the ad was.

Frequently asked questions

Are mortgage brokers even allowed to run Google Ads?

Yes — running ads isn't restricted by NCCP itself, but the content of your ads and landing pages needs to stay accurate and avoid overstating outcomes or making promises the licensee can't stand behind. If you're unsure, run your ad copy past the same compliance process you'd apply to any client-facing marketing material.

How much should a mortgage broker budget for Google Ads?

It varies a lot by region and competition, but most brokers see workable data once they're spending enough to get 20-30 clicks a week per campaign. Starting smaller and scaling once cost per lead settles down is generally safer than launching with a large budget across everything at once.

Can Google Ads guarantee a set number of leads per month?

No, and it's worth being wary of anyone who promises this. Search volume for loan-related keywords fluctuates with the market, interest rate news cycles and seasonality, so lead volume will move month to month even with a well-optimised account. What a well-structured account can promise is that more of your budget is spent on people who could plausibly become clients — not a fixed number of them.

Do I need a separate landing page for each loan type?

Ideally yes, at least for the loan types with real budget behind them. Even a single well-written paragraph tailored to that search intent, sitting above your regular enquiry form, lifts conversion measurably compared to sending every click to the homepage.
