SEO crawlers map links, keywords and technical issues for SEO tools and backlink databases.
They help the tool's customers, often your competitors, rather than you. Rate limit or block the ones you do not use.
Of the 24 SEO crawlers with a stated policy, 24 follow robots.txt and 0 do not. Bots that ignore robots.txt can only be stopped by user agent or IP at your server, CDN or WAF.
Transfon Security identifies every bot in this directory in your traffic reports, flags fake search crawlers, and lets you allow, block or rate limit each bot.
Privacy, security, monetization, and performance insights. A few emails a month, no spam.
