Frequently Asked Questions
What is a robots.txt file?
A robots.txt file is a plain text file placed at your domain root that instructs web crawlers which pages they can or cannot access. It's the first file Googlebot reads when visiting a site. Misconfigurations blocking important pages or the sitemap URL are one of the most common technical SEO mistakes.
Should I block AI crawlers in robots.txt?
Optional — Google's confirmed that blocking AI training crawlers (GPTBot, CCBot, ClaudeBot) has no effect on traditional search rankings. If you don't want your content used for AI training, block them. If you want AI search tools (Perplexity, ChatGPT) to cite your content, don't block them.
Does robots.txt prevent indexing?
No. Robots.txt prevents crawling, not indexing. A page can appear in search results without being crawled if it has external links pointing to it. To prevent indexing, use a noindex meta tag on the page itself — robots.txt alone is not enough.
Is my data stored?
No.
Can I use this on mobile?
Yes.
