Frequently asked questions

What is a robots.txt file?

A robots.txt file tells search engine crawlers which pages or sections of your site they should or should not access. It's placed in the root of your website (e.g. https://example.com/robots.txt) and read by crawlers before they visit any other page.

Does blocking a page in robots.txt hide it from Google?

No — robots.txt prevents crawling but not indexing. Google can still index a page it hasn't crawled if other sites link to it. To prevent indexing, use a noindex meta tag or X-Robots-Tag header instead.

Should I block AI crawlers?

This is a personal choice. Blocking AI crawlers (GPTBot, Claude-Web, CCBot, etc.) prevents your content from being used to train AI models. It has no effect on Google search rankings. Many publishers are choosing to block them to protect their content.

What happens if I have no robots.txt?

Without a robots.txt, all crawlers are allowed to access all public pages. This is fine for most sites. A missing robots.txt returns a 404, which crawlers treat as "allow all".

robots.txt vs noindex — what's the difference?

robots.txt controls crawling (whether search engines visit the page). The noindex meta tag controls indexing (whether search engines include the page in results). A common mistake is using robots.txt to hide pages — blocked pages can still appear in search results if linked from other sites. Use noindex for true invisibility.

Should you block SEO crawlers?

Tools like Ahrefs and Semrush use their own crawlers to build backlink databases. Blocking them in robots.txt stops them crawling your site but won't remove your site from their databases (they get data from other sources too). Block them if you're concerned about competitor research, but it's largely a cosmetic measure.
