Understanding robots.txt

Crawler Control

Tell search engine crawlers which parts of your site they should and shouldn't request.

Crawl Budget

Disallow low-value paths (admin panels, internal search results) so crawlers spend time on pages that matter.

Sitemap Discovery

A Sitemap directive helps crawlers find your full list of indexable URLs faster.

Local Processing

Your rules never leave your browser — the file is built entirely client-side.

robots.txt Is a Suggestion, Not a Lock

robots.txt relies on voluntary compliance — well-behaved crawlers like Googlebot respect it, but it cannot actually prevent a page from being accessed or block malicious bots. It also doesn't hide a URL from search results if other sites link to it; use a noindex meta tag or password protection for content that truly needs to stay out of search results.

Key Takeaways

Standard Format: Generates a robots.txt following the Robots Exclusion Protocol.
Must Be at the Root: Save the output as /robots.txt at your domain's root to take effect.
Client-Side Only: All generation happens locally in your browser — no data is ever sent to a server.
