Branded search volume in the US dropped 11.1% over the month despite stable auction activity in contextual advertising — a Performance-marketing agency published data in MarTech showing that the metric no longer reflects actual brand demand. Customer acquisition cost for branded queries remains 76.6% lower than for non-branded ones, but search volume is shrinking even as audience interest stays steady.
Why branded search no longer works as a demand indicator
Marketers have used branded search query volume as an audience interest indicator for decades. The logic was straightforward: if a user searches for a specific brand, they've already formed a preference and are ready to buy. Google Keyword Planner and Semrush data long supported this correlation.
The analysis ruled out three obvious explanations for the decline. First — weakening brand preferences among the audience: normalized Google Keyword Planner data shows no such trend. Second — reduced search result clickability: Rand Fishkin's research confirms an overall CTR drop in search, but navigational queries by Semrush classification maintain their previous click levels. Third — macroeconomic downturn: overall search query volume remains stable, ruling out a drop in purchasing demand.
Consumers aren't searching for brands less often — they make decisions before executing a branded search query
How AI-search changes user behavior and marketing metrics
The real reason is the spread of AI Overviews in Google search results. Less than a year ago, AI Overviews appeared in 57.2% of commercial queries for one of the agency's client keywords. By June 2026, this share grew to 95.9%. Artificial intelligence answers questions, compares options, and synthesizes information before the user performs an additional branded search.
Preferences form at the general query stage, while branded search only captures the final step — or doesn't capture it at all if the user got the information they needed from the AI answer. The metric changed, though baseline demand remained the same. This is a measurement problem, not a brand interest problem.
Consequences for budget allocation and media planning
Companies distribute budgets based on metrics they trust. Performance marketing receives a disproportionately large share of investment precisely because it creates the appearance of a direct link between spending and results. When a metric stops reflecting the real process, capital flows inefficiently.
If a marketer sees branded search declining and interprets it as brand weakening, they cut investments in awareness and upper-funnel audience work. In reality, consumer behavior has simply shifted upstream — to the moment when preferences form, before intent is expressed through a search query.
For brands, this means rethinking how to measure effectiveness. Direct metrics like reach, engagement, and brand mentions in purchasing contexts become more important than indirect indicators from contextual advertising. Influencer marketing works at exactly this stage: a blogger shapes audience preferences before they start searching for a specific product. When planning campaigns, the ETC team sets KPIs for awareness and share of voice in the niche, not just direct conversions — this lets brands capture demand at the stage before AI systems "consume" traffic.
Frequently asked questions
Why is branded search declining if demand is stable
Branded search declines due to AI Overviews in Google results, which answer user questions before they perform a branded search. Data shows AI Overviews presence growing from 57.2% to 95.9% of commercial queries over a year. Consumers form preferences at the general query stage, while the metric only captures the final step — or doesn't capture it at all.
How to measure brand interest if branded search doesn't work
Brand interest should be measured through direct awareness metrics: reach in relevant audiences, share of mentions in purchasing context, engagement dynamics, and sentiment analysis of discussions. Branded search remains a useful indicator but shouldn't be the only or primary measure of brand investment effectiveness.
Should I cut brand budget if branded searches decline
No — branded search decline doesn't mean demand is falling; it reflects a change in user behavior. Investments in awareness and upper-funnel audience work become more important since decisions are made before branded searches occur.
