Log File Analysis
01 Definition
Log File Analysis meaning: Reviewing server logs to see exactly how bots and users request your pages.
Log file analysis examines your server's access logs, which record every request including those from search crawlers. It reveals which URLs bots actually visit, how often, and what status codes they receive. This shows real crawler behavior rather than estimates from third-party tools.

Why it matters
How Log File Analysis fits the work
Logs are the ground truth of how crawlers treat your site, so analyzing them helps you spot wasted crawling, missed pages, and error patterns tools might miss.
In context
Log file analysis showed Googlebot spent 40 percent of its requests on parameter URLs, so the team blocked those to refocus crawling on real content.
Practical note
Verify that requests claiming to be Googlebot are genuine before drawing conclusions. Large sites need log tools or sampling, since raw logs can contain millions of lines per day.
