Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

3.0

GPA, above 17 of the 34 other SEO browser extensions we grade

Robots Exclusion Checker is a free Chrome extension that shows, for the page you are on, whether anything stops search engines from crawling or indexing it. It reads robots.txt, meta robots tags, the X-Robots-Tag header and canonical tags and turns the result into a red, amber or green icon. Since version 1.3.0 it also checks whether robots.txt blocks AI crawlers from OpenAI, Anthropic, Google, Perplexity, Meta and Apple.

To get you started, here are 7 things to know about Robots Exclusion Checker, taken from its own pages and our grades.

No rating on record, but nothing to set up: the icon turns red, amber or green on the next page you load.
From our grade for ease of use
  1. 1

    Best for finding what stops a page being indexed

    Robots Exclusion Checker reads robots.txt, meta robots, the X-Robots-Tag header and canonicals for the page you're on, turns the result into a red, amber or green icon, and checks robots.txt against 14 AI bots, for free.

  2. 2

    It is free

    Robots Exclusion Checker has no paid plan at all. The whole extension is a free install from the Chrome Web Store, with no account and no paid version listed.

  3. 3

    Robots.txt rule finder

    When an Allow or Disallow rule affects the current URL, it shows that rule and the full robots.txt with the rule highlighted.

  4. 4

    Meta robots and X-Robots-Tag

    Flags index, noindex, follow and nofollow directives in the HTML and in the HTTP header, and shows the full header with exclusions marked.

  5. 5

    AI bot check

    Checks robots.txt against 14 AI bots from 6 companies, covering training, search indexing and live browsing, and adds an AI label to the icon when any are blocked.

  6. 6

    A 3.0 GPA, above 17 of 34

    That is against the other SEO browser extensions we grade, on value, the free plan, features, ease of use and platforms.

  7. 7

    Keep it

    Robots Exclusion Checker is free, so making your own would save you nothing.

The report card

Best for finding what stops a page being indexed

Robots Exclusion Checker reads robots.txt, meta robots, the X-Robots-Tag header and canonicals for the page you're on, turns the result into a red, amber or green icon, and checks robots.txt against 14 AI bots, for free. It's Chrome only, looks at one URL at a time, and the store says EU consumer rights don't apply because the developer hasn't identified itself as a trader.

ToolGPA report cardRobots Exclusion CheckerGraded Oct 23, 2026

Value for moneyAFree from the Chrome Web Store, with no account and no paid version listed.

FeaturesCRobots.txt rules highlighted, meta robots and X-Robots-Tag, canonical mismatch warnings, 14 AI bots from 6 companies, nofollow, ugc and sponsored links, and Googlebot or Bing user-agents. It does indexing checks fully, a smaller job, with no headings or search data.

Grade point averageVery good, out of 4.03.0

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who Robots Exclusion Checker is for

  • Fits if you need to know why a page isn't being crawled or indexed
  • Works for checking at a glance whether a site blocks AI crawlers

Who it is not for

  • Skip it if you're not on Chrome, as no other browser is named
  • Too light for whole-site audits, since it reports on the URL open in the browser
  • Not for you if you want the interface in a language beyond English, German, Spanish and French
  • Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply

Good to know

Good for

  • SEOs checking why a page is not being crawled or indexed
  • Reviewing robots rules behind faceted navigation on large sites
  • Seeing at a glance whether a site blocks AI crawlers

Worth knowing

  • It is listed for Chrome only; the store listing names no Firefox, Safari or Edge version.
  • It reports on the URL open in the browser, one page at a time, rather than auditing a whole site.
  • The developer has not identified itself as a trader, so EU consumer rights do not apply, as the store listing notes.
  • The interface comes in English, German, Spanish and French only.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

Robots Exclusion Checker is free, so making your own would save you nothing.

And it is not the kind of software a weekend replaces.

What you could not

  • A crawler that checks every page of a site.
  • The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept.

What this rests on. Robots Exclusion Checker’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
