SEO Log File Analyzer by Kunal Dabi
SEO Log File Analyzer by Kunal Dabi is a free web tool for examining Apache and Nginx access logs. It reports crawler activity, crawl-budget use, indexability, bot traffic, and response-time patterns. The analyzer shows requests to indexable HTML, assets, and low-value paths such as /wp-admin/. It tracks crawlers including Googlebot, Bingbot, Yahoo, DuckDuckBot, ChatGPT, Perplexity, AhrefsBot, SemrushBot, Applebot, and Bytespider. Sitemap URLs can be compared with bot-crawled URLs to find uncrawled pages. Reports include status-code and content-type breakdowns, per-bot charts, crawl coverage, and an action plan, with URL and error lists exportable to CSV. Response times are measured at p50, p95, and p99. Multiple.log,.txt, or extensionless files can be combined. The Free Log File Analyzer plan costs nothing, is free forever, and requires a daily access code.
