AI Overviews now surface in 83% of branded US searches, Ahrefs data shows

AI Overviews appeared on 82.91% of the branded US desktop Google results tracked by Ahrefs as of September 29, 2026, according to an analysis published on dev.to. The number, drawn from a quarter's worth of crawling, points to a rapid shift in what a branded search results page looks like — and in how much of it a brand actually controls.

What Ahrefs measured

The analysis rests on 232.8 million crawls of US desktop Google results carried out between July and September 2026. Of those, 92.5 million covered branded keywords and 140.2 million covered non-branded keywords. Within the branded set, the share of results pages featuring an AI Overview climbed steadily: 61.3% in July, 65.1% in August and 73.3% in September.

The headline 82.91% figure is a snapshot from September 29, which Ahrefs reported separately from its monthly averages. The two numbers describe the same trend but should not be mixed, and neither should be read as an estimate across all Google searches.

The dataset also has clear boundaries. It covers US desktop results only, depends on Ahrefs' own crawling infrastructure and its definition of the feature, and focuses on a keyword set where AI Overviews were already relatively common. How the feature behaves on mobile, in other countries or across the full query universe is not captured here.

Why branded queries are the pressure point

Branded searches are rarely just navigation. People use them to vet a company, compare it with rivals, check reviews, or find support and pricing details. When a generated answer occupies that results page, a brand's visibility depends not only on where its own pages rank but on whether Google can assemble accurate information about the brand from anywhere on the web.

Ahrefs adds a technical wrinkle: an AI Overview can appear in more than one position on a single results page. That undermines traditional rank tracking as a faithful record of what a searcher sees. A site can hold a strong organic position while an AI-generated summary reshapes the prominence of links and cited sources around it.

What the data says about clicks

Ahrefs' numbers do not by themselves prove a traffic hit, but the company has related evidence. In a separate February 2026 update, Ahrefs reported that top-ranked content showed a 58% lower click-through rate when an AI Overview was present on the page. That is an observed correlation in Ahrefs' data, not proof that every AI Overview costs the same share of clicks, or that the feature alone caused the decline.

Taken together, though, the direction is clear: branded results pages increasingly answer the question before the searcher reaches a page the brand owns.

What teams should now be measuring

Classic brand SEO reporting — rankings, impressions, clicks, branded organic traffic — still matters, but it no longer answers whether a brand is represented correctly inside generated answers. Ahrefs positions its Brand Radar product around this gap, covering six AI platforms and metrics such as mentions, citations and share of voice.

The practical questions to separate are: does the brand still rank well in standard organic results; do AI Overviews appear for priority branded and comparison queries; which sources get cited in those answers; is the brand described accurately next to competitors; and do clicks behave differently where AI features are present. This is as much an AEO and GEO measurement problem as a ranking problem.

One methodological caveat deserves flagging: Ahrefs says it switched to an AI-adjusted volume methodology around August 31, 2026. Anyone comparing trend lines across that date should account for the change, since a measurement adjustment can affect comparability even when the underlying shift is real.

Why it matters

Branded search has long been treated as the defensible core of organic traffic — the queries where a company could count on being found. If roughly four out of five branded desktop results pages in Ahrefs' dataset now carry a generated answer, that assumption erodes. Brands and publishers are increasingly competing for presence inside a summary they do not control, built from sources they often do not own. The numbers describe a genuine change in the results page, but they are not a direct read on traffic or conversions — they are a signal that query-level analysis of AI visibility has become a required part of search reporting.
