What it is

SEOultra Server Log File Crawl Analyzer is a free web tool that reads server logs to show how search engines, AI crawlers, and SEO tools visit a site. It accepts standard Apache or Nginx combined and common access-log formats. Parsed lines are matched against more than 40 signatures covering search, AI, SEO, social-preview, and uptime-monitoring crawlers. Reports segment activity by crawler, break down 2xx, 3xx, 4xx, and 5xx responses, and identify frequently hit error or redirect paths. The analyzer flags hits on session IDs, tracking parameters, and other low-value URL patterns. It can also flag likely impersonation when a declared user agent conflicts with an operator’s published signature, although that does not prove IP ownership. Unknown 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. Controls analyze, load samples, or clear input.
