Free SEO Log File Analyzer
Upload your server access log (Apache/Nginx Combined Log Format) to see how search engine bots crawl your site.
Free SEO Log File Analyzer
Log files are the most honest data source in SEO — they show exactly what happened between your server and the bot, with no sampling, no estimation, and no API limits. Our free analyzer extracts every insight in seconds.
What Log File SEO Analysis Reveals
True Crawl Frequency
Which pages is Googlebot visiting daily, weekly, or never? Log data reveals Google's actual crawl priority for your site — often very different from what you assume based on content quality alone.
Bot Error Exposure
Repeated 404 errors, 500 server errors, and timeout responses to Googlebot are invisible from Google Search Console until they cause index coverage issues. Log files show you every error in real time.
Multi-Bot Analysis
Our analyzer identifies Googlebot, Bingbot, AhrefsBot, SemrushBot, and other major crawlers separately — so you can compare how different engines allocate resources across your site differently.
How to Download Your Access Log
For Apache servers, access logs are typically located at /var/log/apache2/access.log. For Nginx servers, look at /var/log/nginx/access.log. If you're on managed hosting (WP Engine, Kinsta, SiteGround), check your hosting control panel's "Logs" section. Our free analyzer supports the Combined Log Format used by both Apache and Nginx by default.
After analyzing your logs, verify findings against your Free Crawl Budget Simulator to understand whether the wasted crawl paths you see in the logs are caused by robots.txt gaps or internal linking patterns discovered by the Free Internal Link Audit Tool.
