OnCrawl
OnCrawl is assigned to the SEO category by BotScope. Detection is based on the user-agent string. Current pattern:
www\.oncrawl\.com
SEO tool crawlers build internal databases for tools like Ahrefs, Semrush, Sistrix or Majestic. They have no direct SEO impact — only the tool accesses the data. Crawl frequency grows with your domain authority.
BotScope maps OnCrawl requests onto your session timeline — you spot bursts, can filter them per path, and compare against other bots in the same category.
robots.txt directive for OnCrawl
If you don't want OnCrawl to crawl your site, add the following block to your /robots.txt. This works only for bots that honour robots.txt — malicious crawlers ignore it.
User-agent: OnCrawl Disallow: /
