Definition

Log file analysis is the examination of server log files to understand how search engine and AI crawlers interact with a website — revealing which pages are being crawled, how often, which bots are active, and which pages are returning errors or slow responses. Log file analysis is the ground truth of AI crawler behavior. Where Google Search Console shows indexation status, log files show which specific bots (GPTBot, ClaudeBot, PerplexityBot) are accessing which pages and how frequently. For brands investing in AI SEO, periodic log file analysis identifies which AI crawlers are active on the site, whether key pages are being crawled at appropriate frequency, and whether any AI bots are encountering errors or being inadvertently blocked.
