Screaming Frog SEO Log File Analyser
Screaming Frog SEO Log File Analyser · Henley-on-Thames, Oxfordshire, UK · founded 2010
What it is
Screaming Frog SEO Log File Analyser is a desktop application for examining access logs and understanding search engine and AI bot activity. It installs locally and stores log events in a local database. The analyser accepts Apache, W3C Extended, and Amazon Elastic Load Balancing logs, and can verify supported search and AI bots to help identify spoofed requests. Reports cover crawled URLs, crawl frequency, response errors, redirects, bytes downloaded, and response times. Users can import data with a URLs column to match against log activity, including crawls, directives, or external link data. Log files can be added by drag and drop, and analysis can be exported to CSV and Excel. The software can process millions of log events, though capacity depends on hard drive capacity. It runs on Linux, macOS, and Windows, and free technical support is listed for both editions. The free plan allows 1,000 log event lines and one project. The paid licence costs $139 a year per user and provides unlimited events and projects, subject to storage capacity.
