Semrush UK AI-Search Study Puts Adobe’s $1.87B Acquisition Under Investor Scrutiny
Semrush released an initial UK study on brand visibility in AI search, finding that prominence differs by market and platform and that appearing in an AI answer does not always correspond to being listed among cited sources. The report arrives as Adobe seeks to show that its $1.874 billion Semrush purchase can generate paid demand from marketers. Investors still need evidence that the acquisition produces revenue, not just additional dashboards.
Semrush's first UK AI-search visibility benchmark, released Oct. 13, draws on seven monthly snapshots from January through July 2026 and spans 57 pages. It separates a brand being mentioned in an AI answer from its website being cited as a source, showing these outcomes can diverge sharply by platform.
In July, Tesco ranked 25th among ChatGPT's UK cited domains while Asda ranked 606th; on Gemini they placed 29th and 60th. Across 22 categories and four platforms, fewer than half of the top-100 mentioned brands also appeared among the top-100 cited sources each month in both countries. Adobe paid $1.874 billion for Semrush, with roughly two-thirds recorded as goodwill.
The findings may affect marketers, publishers, and consumers as AI-generated answers increasingly mediate product discovery. Brands able to track and improve citations could gain visibility, while smaller businesses may struggle if such tools and expertise remain costly. Consumers could benefit from clearer source attribution, but may also encounter answers shaped by uneven optimization. For investors, the larger social question is whether AI-search measurement becomes a useful market signal or another layer of dashboards with limited accountability.
