What a Home Brand's 21x ROAS Actually Hides

I pulled ninety days of Google Ads data on two home and furniture brands I run. Both report a blended return on ad spend north of 20x. One reads 21.7x, the other 20.4x. On the dashboard, both look like the ads are printing money.

They are not. The blended number is hiding where the revenue comes from, and once you break it apart the story flips.

The two accounts, broken apart

Between them, the two brands spent about $13,500 on Google Ads in the last ninety days and tracked roughly $284,000 in revenue. That is the 21x. Here is what it is made of.

Each account runs two campaign types: a Performance Max campaign that carries most of the budget, and a smaller Shopping campaign. When you split the ROAS by campaign type, the average comes apart.

• Shopping was 18% of the combined spend and produced 52% of the tracked revenue. Its ROAS was 61x.
• Performance Max was 82% of the combined spend and produced 48% of the revenue. Its ROAS was 12x.

Per brand it is even sharper. One brand’s Shopping campaign reported a 45x return. The other’s reported 71x. Their Performance Max campaigns, the ones doing four-fifths of the spending, reported 17x and 8x.

A single small campaign, less than a fifth of the budget, is carrying the headline number for both accounts.

Why the Shopping campaign reads 60x

A 60x or 70x ROAS is not skill. It is intent. Shopping campaigns are very good at catching people who are already most of the way to buying. Someone who searches the brand by name, or searches the exact product they already saw on Instagram, and clicks the Shopping listing. That click was going to convert with or without the ad. The campaign takes the credit anyway.

That is the same pattern as branded search dressed up as performance. The traffic is real, the sale is real, but the ad did not create the demand. It harvested demand that already existed. Harvesting is cheap and it converts at rates prospecting never will, so its ROAS looks unreal. Because it sits inside the same account as the prospecting, it drags the blended average up and makes the whole thing look healthier than it is.

Why the blended number is the wrong number

If you judge a home brand’s Google Ads on blended ROAS, you make two mistakes at once.

You over-credit the ads. A 21x blended return tells the founder the account is a money machine, so the instinct is to leave it alone. But half of that revenue is demand the brand already had. Strip out the harvesting and the part of the account that is actually buying new customers is running at 12x, and on one of the two brands, 8x.

And you starve the part that grows the business. Performance Max, the prospecting layer, is where new customers come from. It runs at a lower ROAS by design, because finding someone who has never heard of you costs more than closing someone who already wants you. Read the blended number and that layer looks like the weak one. Cut it, and you have just cut the only thing creating new demand, while keeping the campaign that was only ever collecting it.

What to actually look at

Separate the harvest from the prospecting before you judge anything.

Pull the ROAS by campaign type, not the account average. Look at what Performance Max returns on its own, and decide whether that number pays back at your margin and your customer lifetime value. That is the real question. The Shopping or branded number is a foregone conclusion, useful for catching tracking breaks, useless for deciding where the next dollar goes.

Then ask the harder question the dashboard will never answer: how much of the harvested revenue would have happened anyway. Incrementality, not attribution. A holdout test on branded and Shopping traffic tells you what the ads are actually adding, and it is almost always less than the platform claims.

The 21x is not a lie exactly. Every dollar in it is real. It is just an average of two completely different jobs, and averaging them together tells you nothing about whether your spend is growing the brand or just taking credit for it.

If you run a home or furniture brand on Shopify, this is the first thing I check, and it is the structure I rebuild every account to. The mechanics of why Performance Max and Shopping fight over the same conversions are in why Performance Max gets credit for Shopping conversions. What a healthy ROAS actually looks like once margin is in the picture is in the ROAS benchmark answer. And the way I structure the whole program for home brands is on the home brands page.
