As of September 29, Ahrefs recorded 82.91 percent of branded searches in the United States returning a Google A.I. Overview, up from a monthly average of 61.3 percent in July. The company drew its reading from 92.5 million desktop crawls of branded keywords. Within a 100-brand panel pulled from Interbrand’s Best Global Brands 2025 list, 63 brands triggered an A.I. Overview by September 30, against just 5 in early July. Of those overviews, 76.2 percent occupied the top position on the results page.

The practical consequence: when a customer types a company name into Google, the first impression is now written by a machine, and it isn’t drawing primarily from the company’s own website.

A parallel study from Slate Research, conducted September 30 to October 1, logged A.I. Overviews on 93 of 100 brand queries after up to three attempts. The 652 citations behind those answers broke down starkly. Only 29 percent came from the brand’s own site. The remaining 71 percent pointed to pages the brand doesn’t control. Thirteen brands supplied none of their own sources at all. Wikipedia appeared in 53 percent of answers; YouTube appeared in another 53 percent. Ahrefs’s own analysis pointed in the same direction, identifying Wikipedia, YouTube, and LinkedIn as the most common external citations for branded AI Overviews.

Six of Slate’s 93 branded answers carried competitor-written content inside the overview itself. Calendly’s cited two scheduling rivals. Gusto’s led with a Trustpilot page and a competitor-authored Gusto-versus-ADP comparison. Pfizer, Toyota, Delta, Starbucks, Verizon, and CVS appeared across the sample. None are small businesses, and that’s the point: if Interbrand-tier brands can’t control their own A.I. summary, a thirty-person company with no marketing staff has no chance by default.

Semrush, tracking 400 commercial-intent keywords from September 2025 through August 2026, logged A.I. Overview coverage at 88 percent in August, up from 45.75 percent a year earlier. Weighted by search volume, coverage reached 97.08 percent. Search Engine Roundtable, aggregating Semrush, SE Ranking, and seoClarity, now places the overall share above 80 percent, with SE Ranking’s U.S. branded figure at 82.5 percent. Three independent datasets, one direction. Prior reporting on this site tracked the commercial-search version of the same shift, and earlier coverage documented the gap on the small-business side.

Branded search is now a multi-channel surface. The owner’s job is monitoring Wikipedia, YouTube, LinkedIn, Google Business Profile, and review sites continuously, because that’s where the summary is quietly being written. LemonLime is built to surface precisely that kind of off-site blind spot proactively.
