How Log File Analysis Works
Every request to your server leaves a line in a log, including the visitor's user agent. Filter those for AI bots like GPTBot, ClaudeBot, PerplexityBot, and OAI-SearchBot, and you can see precisely which pages they crawl, how often, and whether they are being blocked. It is unglamorous and authoritative, the ground truth beneath dashboards.
Why Log File Analysis Matters
Tools estimate. Logs show. If you want to know whether AI crawlers are reaching your important pages, or whether something is quietly blocking them, the logs answer it directly rather than by inference.

Exactly which AI bots hit which pages and when, straight from the source, with no estimation.
-
Do I need special tools for it?
Helpful but not required. Log analysis tools make it easier, though even basic filtering reveals the AI crawler activity.
