What does a robots.txt file actually do for my site?

It sends instructions to search engine crawlers about which pages or files they can request from your site, helping control indexing and keep private areas out of search results.

Should I block AI crawlers like GPTBot in my robots.txt?

Yes, if you don't want your content used to train large language models. Many generators include a preset for blocking AI bots, but note that not all AI respect the standard.

Do I need to include a sitemap URL in my robots.txt?

It's recommended. Adding your sitemap helps search engines discover and index your important pages more efficiently, and most generators have a field for it.

Can I have different rules for Googlebot and other bots?

Yes. You can specify user-agent lines for individual crawlers, allowing or disallowing specific bots while keeping others unrestricted.

Is it safe to use an online robots.txt generator for a large website?

If privacy is a concern, use a browser-based tool that processes the file locally. For simple sites, most online generators work fine, but always review the output before publishing it to your server.

Buyer's guide

How to choose a robots.txt generator

When picking a robots.txt generator, the most important factor is where the file is processed. If you handle sensitive site structures or want guarantees that your crawl rules aren't sent to a third party, choose a browser-based tool so the generated code never leaves your device. If you prioritize a quick, familiar interface and don't mind the tool hosting your input, look for one that lets you copy or download the result without signing in or creating an account.
