Semrush: AI search mentions and citations rarely overlap for brands

Adobe's Semrush published its AI Visibility Index covering January–July 2026: fewer than half of the domains in the top-100 mention lists also appear in the matching top-100 source lists across ChatGPT, Gemini, AI Overviews and AI Mode. Only Apple and YouTube stayed in both lists every month in the US and UK.

• Fewer than half of top-100 mentioned domains match top-100 cited sources
• 24 sites appear consistently in the UK versus 36 in the US, with 15 shared
• Gemini mentions more distinct brands per answer; ChatGPT cites more sources
• UK news sites account for 26.4–34.3% of ChatGPT citation weight, US 15.9–25%
