Robots.txt & crawler FAQ
What is a robots.txt file?
Robots.txt is a plain text file placed at the root of your domain (e.g., https://yourdomain.com/robots.txt) that instructs search engine crawlers and web scrapers which URLs they can or cannot access.
Should SaaS startups block AI scrapers like GPTBot and ClaudeBot?
Many founders prefer to block AI scrapers to prevent unauthorized data mining and save origin server bandwidth, while ensuring Googlebot and Bingbot remain fully allowed for organic search rankings.
Where should the robots.txt file be hosted?
It must be hosted at the exact root of your website: https://yourdomain.com/robots.txt. Subdirectory locations like /assets/robots.txt are ignored by web crawlers.
