What SEOultra Server Log File Crawl Analyzer is
SEOultra Server Log File Crawl Analyzer is a web tool for examining server logs and seeing how search engines, AI crawlers, and SEO tools visit a site. It accepts standard Apache and Nginx combined logs, along with common access log formats, and checks parsed entries against more than 40 recognized crawler signatures. These include search and AI crawlers, SEO tools, social preview bots, and uptime monitors.
Reports separate activity by crawler and summarize 2xx, 3xx, 4xx, and 5xx responses. They also call attention to frequently visited error and redirect paths, and bot requests for session IDs, tracking parameters, or other low-value URL patterns. The analyzer can flag a likely impersonator when a declared user agent differs from an operator’s published signature; this mismatch does not establish who owns the IP address. Unrecognized log lines are skipped and counted. Each analysis handles up to about 8,000 lines or 300,000 characters. Pasted logs are sent once over HTTPS for processing and are not kept beyond the request. Users can analyze pasted lines, load a healthy or problem sample, or clear the input. SEOULTRA names PT. Seoultra Metric Indonesia as its maker and says it began in 2021, working remotely from Singapore and Jakarta.
