Log File Analysis
Definition

This term is part of the full AI search glossary.
Full definition
Access logs record user-agent, path, status, bytes, and timing. SEO teams filter for Googlebot and other crawlers to verify crawl budget use, discover soft 404 spikes, and confirm that important sections are actually fetched after launches.
Analysis pairs well with Search Console and sitemap data: logs show reality on your infrastructure, including bots that never appear in vendor UIs. Sampling, CDN offload, and bot spoofing require careful interpretation.
For AI visibility, logs reveal whether GPTBot, ClaudeBot, and similar agents access docs and product pages or only hit blocked paths. See Crawl Budget, AI Crawler, and User-Agent.
Example
Logs show GPTBot receiving 403 on /docs/* after a WAF rule change, explaining why documentation stopped appearing in AI-cited answers.
