# Robots.txt Tester

> Agent-friendly Markdown of https://www.buildseo.org/free-tools/robots-txt-tester — full index for AI agents: https://www.buildseo.org/llms.txt

Parse any site's robots.txt: groups, rules, sitemap directives, and blockers.

## How it works

Enter any URL on the site and the tester fetches robots.txt from that origin, parses every group and rule, and flags the problems that actually cost rankings — a missing file, a stray Disallow: /, or a missing sitemap directive.

Unrecognized directives are listed so typos don't silently get ignored by crawlers.

Download the result as CSV or JSON, free and instant.

## Frequently asked questions

### I entered a page URL, not robots.txt — is that okay?
Yes. The tester derives the site origin from whatever URL you enter and fetches its /robots.txt automatically.

### Does a missing robots.txt hurt SEO?
Crawlers treat a missing file as allow-everything, so nothing breaks — but an explicit file with a sitemap directive gives crawlers a map and gives you control.

## Crawlable confirmed. Now give crawlers a reason to visit.

Backlinks are how crawlers find you first. BuildSEO AI builds them autonomously and proves every placement with evidence.
