What SEO Log File Analyzer by Kunal Dabi is
SEO Log File Analyzer by Kunal Dabi is a free web tool that turns Apache and Nginx access logs into reports about crawler activity, crawl budget, indexability, and response times. It can show bot requests to indexable HTML, assets, and low-value paths such as /wp-admin/. Tracked crawlers include Googlebot, Bingbot, Yahoo, DuckDuckBot, ChatGPT, Perplexity, AhrefsBot, SemrushBot, Applebot, and Bytespider. The analyzer compares sitemap URLs with URLs crawled by bots to surface pages that have not been crawled. Reports include status-code and content-type breakdowns, per-bot charts, crawl coverage, and an action plan; URL and error lists can be exported to CSV. Response times are analyzed at p50, p95, and p99. Multiple log files can be combined in one run, using Apache Combined logs, Nginx access logs, or similar formats such as .log and .txt. Access requires a daily code, emailed to registered users or obtainable from an administrator. The FAQ says files are processed in memory, not stored on servers, and analysis runs locally in the session.
