Log file analysis is the practice of examining a website’s raw server log files to see exactly how search engine crawlers actually interact with a site — which pages they visit, how often, and whether they encounter errors — providing ground-truth data beyond what standard SEO tools can estimate.
Unlike simulated crawls from third-party SEO tools, log files show real crawler behavior, revealing issues like search engines wasting crawl budget on unimportant pages, failing to crawl important new content promptly, or repeatedly hitting error pages.
Log file analysis is particularly valuable for larger websites where crawl budget efficiency has a meaningful impact on how quickly new or updated content gets discovered and indexed.
Log file analysis is included in our advanced Technical SEO service for larger sites.
