SEOultra Server Log File Crawl Analyzer
SEOultra Server Log File Crawl Analyzer is a web tool that reads server logs and shows how crawlers visit a website.
What SEOultra Server Log File Crawl Analyzer is
SEOultra Server Log File Crawl Analyzer is a web tool that reads server logs and shows how crawlers visit a website. It accepts standard Apache or Nginx combined and common access-log formats, then matches parsed lines against more than 40 signatures for search engines, AI crawlers, SEO tools, social previews, and uptime monitors. Reports segment activity by crawler, break down 2xx, 3xx, 4xx, and 5xx responses, and identify frequently visited error or redirect paths. The analyzer flags hits on session IDs, tracking parameters, and other low-value URL patterns as crawl waste. It can also flag likely user-agent impersonation when a declared agent conflicts with an operator’s published signature, though this does not prove IP ownership. Unrecognized lines are skipped and counted. Each analysis handles about 8,000 lines or 300,000 characters. Pasted logs are sent once over HTTPS and not retained beyond the request. The tool is free.
