## Key takeaways

- Google now points site owners to the robots.txt report in Search Console and its open source parser rather than the old tester.
- The report shows whether Google fetched and parsed the file, not whether a given crawler may fetch a given path.
- seogeoaeo.ai's Robots.txt & AI Crawler Checker answers that path question for search and AI crawlers, with the line to change.

The Google robots.txt tester has been replaced: Google now points site owners to the robots.txt report in Search Console and to its open source parser. For the job the old tester did, entering a URL and seeing whether a bot may fetch it, the closest single tool today is the seogeoaeo.ai Robots.txt & AI Crawler Checker, which also covers the AI crawlers the old tester never knew about.

## What the old tester did

The tester showed your current robots.txt, let you test URLs against it, and highlighted the specific rule behind each decision. You could also edit the file in place and test the changes before uploading them. Google's 2014 post that introduced the updated version now carries a note pointing readers to "the newer robots.txt report."

## What Google offers now

Google's own documentation names two ways to test a file:

- **The robots.txt report in Search Console.** It lists the robots.txt files Google found for your top 20 hosts, with fetch status, last check time, size and parsing issues. You can open the last fetched version and ask Google to recrawl the file after a fix. It works only for Domain properties or domain-level URL-prefix properties, and only for files that are already live.
- **Google's open source robots.txt library.** The parser is on GitHub, and Google suggests developers run it locally to test files.

What is missing is the quick question the old tester answered: may this crawler fetch this path, and which line says so? The report shows whether Google could read the file, not how a given URL is judged. For a single URL, Google's help points to the URL Inspection tool, which needs a verified property.

## Why the gap matters more now

When the tester was built, the crawlers most sites cared about were search bots. Today a robots.txt file also decides access for GPTBot, ClaudeBot, PerplexityBot and Google-Extended, the token that controls whether Google may use your content for Gemini models and grounding without changing how Googlebot crawls for Search. A file that is fine for Googlebot can still block or open the door to AI crawlers in ways the owner did not plan. A modern replacement needs to answer for all of them.

## The replacement options compared

| Need | Tool |
| --- | --- |
| Test a path for Googlebot or an AI crawler, see the matching rule | seogeoaeo.ai checker, 10 credits a run |
| Confirm Google fetched and parsed the file | Search Console robots.txt report |
| Test edits before uploading | Bing Webmaster Tools tester, or Google's library locally |
| Prove what a bot actually fetched | Your server access logs |

The [seogeoaeo.ai checker](https://seogeoaeo.ai/tools/robots-checker) takes a site URL plus an optional path and crawler token. It lists every rule that blocks a search or AI crawler, shows the rule that matches your path and gives the line to change. It works on any public site, and AI agents can call it over REST or MCP. It does not fetch the tested page or prove a crawler obeys the file; robots.txt is a request, not a lock.

## The honest trade-off

If you mainly want to know what Google itself saw, the Search Console report is the authoritative source. If you want to try a draft file before publishing, Bing's tester has an editor for that. For the old tester's core question, asked about Google and AI crawlers at once, seogeoaeo.ai is the pick.

## Frequently asked questions

### Where is the robots.txt tester in Google Search Console?

Google's 2014 post about the tester now points readers to the newer robots.txt report, and Google's documentation names that report and its open source robots.txt library as the ways to test a file.

### Does the robots.txt report show AI crawler access?

No. It covers Google's fetch and parsing of the file. To see whether GPTBot, ClaudeBot, PerplexityBot or Google-Extended are allowed, use a checker such as seogeoaeo.ai's.

### Can I still test robots.txt edits before publishing?

Yes. Bing Webmaster Tools has a robots.txt tester with an editor, and Google's open source library runs locally.
