The 4% Trap: Google Ads Incrementality

"Google is just remarketing." We've audited 100+ accounts. Here's why that take is 96% wrong.

The critics focus on brand search. Someone Googles your brand name, clicks your ad, buys. You would've gotten that sale anyway. Fair argument.

But here's what they miss.

Brand search is maybe 4% of what Google Ads actually does.

The other 96%? Non-brand Shopping and Search. Someone searches "white running shoes." They don't know you. They're comparing 5 options. They can click a competitor just as easily.

That's not remarketing. That's acquisition.

322 incrementality tests (Measured, 2025) found PMax delivers a median iROAS of $2.02. Non-brand drives 63% new customers. These aren't people who were coming anyway. They were choosing.

The incrementality debate isn't wrong. It's just pointed at the wrong 4%.

Most brands we audit have the same blind spot. They split brand and non-brand (good - that's hygiene). Then they stop. Hero SKUs eat 95% of spend while 400 other products sit unused.

You're not demand-capped. You're structure-capped.

The real question isn't "is Google incremental?" It's "at what ROI level is your non-brand incremental enough to scale?"

Fix the engine. Then debate the philosophy.
