Traffic-intelligence vendor whose panels produce the beat's most-quoted scale figures — AI Overviews on 43% of searches, ChatGPT's 494 million users.
Similarweb's panels supply the beat's most-quoted scale figures. Its analysis put AI Overviews on 43% of Google searches in July 2026, up from 15% a year earlier, and counted AI Mode visits rising from 126 million in June 2025 to 279 million in May 2026; a separate report found 95% of ChatGPT's 494 million users also used Google in the same March-to-May window. Its Top 100 Media index underlies the finding that publishers spent an estimated $113 million on Google paid search in July 2026, up 274% over three years, with Forbes at $72.2 million as its organic traffic fell 26.7%. On the product side Similarweb added AI Ads to its Ad Intelligence product on August 13 — creatives and landing pages running inside ChatGPT, AI Mode and AI Overviews — and is building an agentic-commerce measurement product with NIQ. Methodology detail — panel size, geography, sampling — is thin on this record.
