Shopify Growth

Shopify revenue is up but Meta and Google ROAS are down

These two numbers can move in opposite directions without anything being wrong. Total store revenue and platform-reported ROAS answer different questions, and the gap between them usually comes down to where the growth is actually coming from.

Growth the ad platforms don't get credit for

Say a store grew total revenue 20% year over year while Meta and Google ROAS both fell. If most of that growth came from returning customers buying again through email, direct visits or organic search, the ad platforms had little to do with it — they're reporting on a shrinking share of a growing pie, which looks like underperformance even if new-customer acquisition through ads held steady.

Illustrative — the actual split will differ by store.

Check new-versus-returning customer mix first

Shopify's customer reporting can split revenue by new and returning buyers. If returning-customer revenue explains most of the growth, that's largely a retention and brand story — worth understanding, but not evidence that paid acquisition is failing. If new-customer revenue is also growing but ad platform ROAS is still falling, that's a stronger signal that acquisition efficiency is genuinely softening, or that measurement is under-reporting what the ads are actually doing.

Don't rule out tracking either

A tracking or consent change can suppress platform-reported purchases even while real Shopify revenue keeps climbing — they're measured independently. If reported ROAS dropped around the same time as a site, cookie-banner or app change, it's worth ruling that out before concluding the campaigns themselves got less efficient.

Common questions

Does falling platform ROAS always mean the ads got worse?

No. It can also mean growth from other sources is diluting the ad platforms' apparent share of total revenue, or that tracking is under-reporting platform-attributed orders even as real sales grow. Check new-versus-returning customer mix before assuming the ads themselves are the problem.

How do I check if it's returning customers driving the growth?

Shopify's own customer reporting can split revenue by new versus returning customers. If returning-customer revenue is doing most of the growing, that's largely retention and brand strength, not new-customer acquisition — a different lever than your ad accounts.

Should I keep spending on ads if ROAS looks worse but revenue is up?

That depends on whether new-customer acquisition itself is still efficient, which platform ROAS alone won't answer cleanly. It's worth looking at new-customer CAC specifically rather than reacting to a blended ROAS number that's being pulled around by channels the ad platform had nothing to do with.
