Frequently Asked Questions
What is a robots.txt file?
A robots.txt file is a plain text file placed at the root of your website (e.g., https://example.com/robots.txt) that tells search engine crawlers which pages or sections they are allowed or not allowed to access. It uses the Robots Exclusion Protocol, supported by all major search engines.
Should I allow or block AI crawlers like GPTBot and ClaudeBot?
Allowing AI crawlers means your content can appear in AI-powered search results from ChatGPT, Claude, and Perplexity. Blocking them prevents your content from being used for AI training and search indexing. Most websites should allow AI crawlers unless they have a specific reason not to — many sites inadvertently block them with blanket Disallow rules.
What happens if I don't have a robots.txt file?
Without a robots.txt file, all crawlers assume they are allowed to access the entire site. This is the same as having "User-agent: * / Allow: /" in your robots.txt. Missing robots.txt is not harmful, but it means you can't block crawlers from private sections or specify your sitemap location.
Does robots.txt prevent pages from appearing in search results?
Robots.txt prevents crawlers from accessing pages, but it does not guarantee those pages won't appear in search results. If another page links to a blocked URL, Google may still index it from the link without crawling the actual content. To prevent a page from appearing in search results, use a "noindex" meta tag instead.
Where do I upload my robots.txt file?
The robots.txt file must be in the root directory of your domain, accessible at https://yourdomain.com/robots.txt. It cannot be in a subdirectory like /blog/robots.txt. In most web frameworks, this means placing the file in the public/ or static/ folder. After uploading, verify it at the robots.txt URL and test it with Google Search Console.
