Screaming Frog Log File Analyser

While the standard SEO Spider tool crawls your live website to show how it is structured, the Log File Analyser reveals how search engine bots actually interact with those pages in real time. It parses raw server access logs to show precisely which URLs Googlebot is crawling and how much server bandwidth it consumes.

By examining raw server logs, the tool uncovers issues like redirect chains, 404 errors, and wasted crawl budget that might be invisible to a standard crawler. This allows webmasters to optimize their robots.txt files and site architecture to prioritize Googlebot crawling high-value pages.

Yes, it serves as a highly valuable complement to Semrush's broader analysis capabilities by providing deep, server-level data. While Semrush is excellent for keyword research and competitor traffic analysis, Screaming Frog provides the granular technical data needed to fix underlying server and crawl issues.

The tool supports a variety of common log file formats, including those generated by Apache, Nginx, and Microsoft IIS servers. Users can easily upload or drag-and-drop compressed ZIP or GZ log files directly into the desktop application for rapid analysis.
