How engaged are visitors who arrive from AI assistants?
About 41% of AI-referred sessions were engaged sessions, 1,085 of 2,654, according to GA4. Perplexity visitors engaged most often at 46%, and Copilot visitors least often at 32%.
| AI engine | Engaged sessions | Engagement rate |
| Perplexity | 215 of 464 | 46% |
| Gemini | 367 of 887 | 41% |
| Claude | 228 of 554 | 41% |
| ChatGPT | 221 of 581 | 38% |
| Copilot | 54 of 168 | 32% |
GA4 recorded no conversion events from any AI-referred session in the period, so this tracker reports traffic and engagement, not leads.
Which pages does each AI engine send visitors to?
Each AI engine sent visitors to a different set of pages, and the largest single landing page was a ranking of public affairs firms from ChatGPT with 76 sessions. The table lists the top named landing pages GA4 reported for each engine.
GA4 reported old paths for four of these pages, which now redirect to the addresses linked above. GA4 also recorded no landing page for 439 sessions, led by Gemini with 151 and Claude with 114.
What does the shift from ChatGPT to Gemini mean for a PR team?
A PR team should check which of its own pages each engine sends visitors to before deciding where to invest, because the engines favored different pages on this site. Gemini's top pages were case studies and ranked lists, while ChatGPT's top page was a firm ranking and Claude's was a citation index.
The comparison also shows referral share can move within one quarter: Gemini nearly tripled while ChatGPT fell by a third.

How is this tracker measured and updated?
This tracker counts GA4 sessions whose source is an AI assistant's own domain: gemini.google.com, chatgpt.com, claude.ai, perplexity.ai and copilot.microsoft.com. Each figure covers the 90 days ending October 17, 2026, compared with the 90 days before.
The counts are visitors who clicked a link inside an AI answer, not mentions or citations without a click. Engines that send traffic without a recognizable source domain are not counted. Everything-PR plans to update the tracker each quarter, with the next update due in January 2027.
