Some are real, most aren't. A genuine guarantee has a testable shape: a specific number written down for you, a dated trigger you can measure, every condition visible before you sign, and a remedy you'd actually want. Most marketing "guarantees" are built so the conditions can never quite be met, which makes them a sales line, not a promise. In Australia it is actually illegal to misrepresent a guarantee, and this guide gives you a six-question test to tell the two apart, including a test I run on my own guarantee at the end.
There's a line I've heard from more than one burned owner: "I stop reading the moment someone says they guarantee leads." That instinct is correct, and it's a problem for me, because I offer a guarantee. So I'm not going to ask you to trust mine. I'm going to hand you the tools to judge any guarantee, mine included, and then show my working.
I looked at how these things are actually written, and the pattern is consistent. The promise in the headline is bold. The terms that decide whether it ever pays sit somewhere else, and they quietly take it all back. A few of the common shapes:
The "beat your results or we work for free" guarantee. Sounds fearless. Read closer and it usually only applies to campaigns that are already profitable, so the agency is quietly pre-selecting winners. They control the creative, and they decide what counts as a fair comparison. The risk transfer is mostly an illusion.
The "pay on performance" guarantee. "No results, no invoice." The catch lives on a separate terms page: the free work is capped, the targets are defined loosely, and it's often voided if anything on your side changes. The headline is readable. The part that matters isn't.
The "page one of Google or your money back" guarantee. Watch for the missing details. No timeframe, no specific keywords, and in one live example I found, the money-back terms page itself returned a 404, an error, nothing there at all. A guarantee whose terms you literally cannot read is not a guarantee.
The effort guarantee. The sneakiest, because it sounds warm. "We guarantee to work hard and use our best methods." There is nothing to invoke. A promise to try transfers no risk to them and gives you nothing to hold.
None of these are necessarily illegal on their own. But they share one trait: the promise you remember and the terms that govern it are not the same thing, and they're rarely in the same place.
And there's a reason a genuine guarantee is rare. An honest one is expensive to offer, because you actually have to pay when you miss. That cost is the whole reason it means anything. A guarantee engineered never to pay costs the seller nothing, which is exactly why it signals nothing.
Here's what almost no article on this topic will tell you. In Australia, a misleading guarantee isn't just poor form, it's against the law.
The Australian Consumer Law specifically makes it illegal to make a false or misleading representation about the existence or effect of a guarantee. And the regulator is clear that fine print can't be used to contradict the headline: qualifications "must not conflict with the overall message" of the ad. A guarantee whose small print cancels its big print is the exact thing the law names.
This isn't theoretical. A company called Get Qualified Australia advertised a "100% money back guarantee" while, in the regulator's words, almost always declining refund requests. The Federal Court ordered $8 million in penalties against the company and $500,000 against its director. It was an education business rather than a marketing agency, and to be straight with you, I couldn't find a marketing agency prosecuted specifically over a guarantee. But the conduct, promising something you don't intend to honour, is illegal whoever does it, and the penalties for it doubled to $100 million per breach in March 2026.
Even Google says it plainly in its own guidance for hiring help: "No one can guarantee a #1 ranking on Google. Beware of SEOs that claim to guarantee rankings." When the platform itself tells you a guarantee is impossible, and an agency offers it anyway, you have your answer.
One more thing worth knowing. Underneath any promotional guarantee, you already have statutory rights no contract can remove. Any service under $100,000 must be delivered with due care and skill. A flashy guarantee sits on top of those rights, never instead of them.
So how do you tell a real guarantee from theatre? Ask these, in order. A real one answers yes to all six.
That last one is the fastest filter, so let me use it on myself.
I'd be a hypocrite to hand you that test and dodge it, so here's my guarantee run through all six, limits and all.
The number is specific and written down, agreed for your business before we start, based on your economics and budget, not a figure I pull from the air. The trigger is measurable and dated: a set number of qualified appointments in your calendar within a window, usually 30 days from your first lead. The conditions are on the table before you sign, including the one that matters most, that you fund your own ad spend, paid to the platform and not to me. The remedy is real: if I miss, I keep working at no fee, and if I still miss, you owe me nothing and we part as friends.
And here's the limit, because a test you can't fail isn't honest. My free work is capped at 60 days. I'm not promising to work for free forever. That's a promise nobody could keep, and you should distrust anyone who makes it. What I'm promising is a defined number, a defined window, a capped downside, and no bill if it doesn't land. You can hold me to every word of that, and you can read all of it before you commit a cent.
That's the whole point of this guide. Not "trust my guarantee." Test it, the same way you'd test anyone's.
