Log file analysis enables you to discover which pages search engine bots crawl most and least frequently. By identifying low-value or irrelevant pages that consume your crawl budget—such as empty category pages or duplicate content—you can take steps to block or remove them. This ensures that Googlebot focuses its crawl resources on your most valuable pages, improving crawl efficiency and potentially boosting your site's search performance. Techniques include updating your robots.txt file to block unnecessary URLs, implementing canonical tags to consolidate duplicate pages, and removing outdated or low-quality content. Regular log file audits help maintain optimal crawl budget allocation. [Semrush]
