See which AI bots read your site, and which answers send visits.
Lighthouse logs GPTBot, ChatGPT-User, ClaudeBot, PerplexityBot and the other AI crawlers on every page, and shows your GA4 and Search Console data beside your AI visibility.


Sample data for Ridgeline Outfitters, a fictional brand.
How do I know if AI crawlers can read my site?
Check your server logs or a crawler tracker for the user agents of each AI engine, and check robots.txt for rules that block them. Lighthouse does both continuously: it records every visit from AI crawlers by page, flags pages they cannot reach, and reports which blocked bots are costing you answers.

Disallow: /What can you do with AI crawlers and referrals?
Every AI crawler, by page
A one-line snippet or a Cloudflare integration logs each AI bot visit with the page, status code and time.
Blocked and broken pages
Pages that return errors to bots, sit behind scripts they cannot render, or are disallowed in robots.txt.
AI referral traffic
Visits from AI engines in GA4 and the pixel, shown beside your AI visibility trend.
Shadow pages
Machine-readable pages built for AI agents, served alongside your site, with their own crawl stats.
Every number opens to the answers behind it.
Every answer collected from the engine’s own logged-out page in a real browser, stored with its sources and a screenshot, and never estimated from a panel.
Read the methodologyQuestions people ask
Should I block GPTBot?
GPTBot collects training data; OAI-SearchBot fetches pages for ChatGPT search answers. Many brands block the first and allow the second. Blocking OAI-SearchBot removes you from ChatGPT search citations, which is the most common fix we find.
Do I need to install anything?
Either a Cloudflare worker or a small tracking pixel. Neither sets cookies or tracks people. Server-log upload is not available yet.
