A branded query contains the brand name or an unambiguous brand variant — “allbirds shoes”, “warby parker glasses near me”. A non-branded query describes the product or the need without naming the brand — “running shoes”, “blue light glasses”. The line is whether the searcher already knows who they want to buy from.
That line matters because the two query types represent different demand. Branded search captures intent the brand has already created upstream through paid social, organic content, influencers, retail presence, or word of mouth. Non-branded search competes against the rest of the category for users still in consideration. The same platform reports usually show branded with lower CPCs, higher CTRs, and higher CVRs, but those metrics describe where the demand came from, not the efficiency of the paid-search channel.
This is where one of the most common DTC attribution mistakes lives. Reading branded ROAS as paid-search performance double-counts the upstream channel that produced the query, and treating branded paid clicks as cheap acquisition flatters apparent CAC without lowering the blended number.
The defensive-bidding question is the operational version. Many brands bid on their own brand terms to keep competitors and resellers off the SERP even though most branded clicks would convert organically. That spend earns its place when a competitor is actively bidding on the term, a retail partner outranks the brand site organically, or the SERP has a paid-organic gap; otherwise it is margin leakage that platform reports show as ad performance.
