Frequently asked questions

What belongs in robots.txt?

User-agent groups with Allow and Disallow paths, optional Crawl-delay, and Sitemap URLs. This generator sticks to those widely supported directives and skips Host, Noindex, and other non-standard lines.

Does Google honor Crawl-delay?

No. Google ignores Crawl-delay. Bing, Yandex, and some other crawlers still use it. The file stays valid if you include it.

Can I use more than one user-agent?

Yes. Add a group per crawler (for example * and GPTBot). Matching groups are combined by the crawler. Sitemap lines apply to the whole file, not a single agent.

Where should I put the file?

Serve it at https://your-domain/robots.txt on the site root. Paths are relative to the host, and Sitemap values must be full URLs.

Is this processed on a server?

No. The file is generated in your browser. Nothing is uploaded to Utilvia.
