<b>How much of your branded search spend is actually buying you conversions you'd have gotten for free?</b>

<b>How much of your branded search spend is actually buying you conversions you'd have gotten for free?</b>

A pointed question, because branded search is consistently the most over-credited line in any attribution report — and one of the most testable.

<b>The setup</b>

When someone searches your brand name, they've already decided to seek you out. Bidding on that term means paying for a click that, in many cases, would have arrived organically just below the ad.

<b>What experiments have found</b>

The landmark evidence is eBay's large-scale search experiment, which paused paid search and found that the vast majority of attributed sales were not incremental — most clicks substituted for free organic visits. Subsequent brand-keyword pause tests across many advertisers replicate the pattern: incremental lift on pure branded terms is often low and sometimes near zero, while last-click cheerfully assigns it a glowing ROAS.

<b>The nuance</b>

It is not universally zero. Branded incrementality rises when competitors bid on your brand, when your organic listing is buried or absent, or when the brand term is broad enough to capture genuine consideration. The answer is account-specific and changes with the SERP.

<b>What to actually do</b>

— Run a brand-term pause test (geo-split or time-split) rather than trusting attributed ROAS. It's one of the cheapest, highest-leverage experiments available.
— Re-test when competitors start or stop bidding on your brand, since incrementality is conditional on the auction.

Bottom line for practitioners: branded search ROAS is where correlation masquerades most convincingly as causation. The pause test is the only honest way to know what you're really buying.
