SEOCheckerBot
User-agent documentation
Why did this bot visit my site?
Someone pasted a URL from your site into the free checker at seoanalysischecker.com. SEOCheckerBot fetched that single page (plus a few standard files like robots.txt, sitemap.xml and llms.txt) to generate an SEO report. It does not crawl your site, does not follow links recursively, and does not revisit on a schedule.
How it identifies itself
Mozilla/5.0 (compatible; SEOCheckerBot/1.0; +https://seoanalysischecker.com/bot)
Behavior
- Fetches one page per user request — no recursive crawling.
- Requests time out after ~20 seconds.
- Repeat checks of the same URL are served from a 24-hour cache to avoid re-fetching.
- Only connects over standard ports 80 and 443.
How to block it
Add this to your robots.txt:
User-agent: SEOCheckerBot Disallow: /
You can also block the user-agent string at your server or CDN. Note that blocking it only prevents people from running SEO reports on your pages with this tool.
