Frequently Asked Questions
Why check bot access?
Blocked bots cannot index your pages. A missing or incorrect robots.txt directive can silently prevent Googlebot from accessing your most important pages.
Can I block AI training bots but keep search bots?
Yes. Use specific User-agent entries in robots.txt: Disallow GPTBot and ClaudeBot while allowing Googlebot and Bingbot.
What is the difference between robots.txt and meta robots?
robots.txt controls crawl access. Meta robots controls indexing. A page can be crawled but set to noindex — or blocked from crawling yet still indexed via backlinks.
Should I block AI training crawlers?
This is a business decision. Blocking prevents your content from being used for AI training but may reduce AI search visibility. Use Google-Extended to block Gemini training without affecting Google Search.
