Grubbomatic Crawl Readiness – AI Crawler Check and Fixes

AI search engines, AI assistants and the crawlers that gather training data all read websites. This plugin checks how yours looks to them, from the outside, and sets it up the way you intend: readable where you want it read, closed to AI training if you choose, with the files AI systems look for.

Grubbomatic Crawl Readiness runs the free readiness check from crawlreadiness.com against your site and shows the result in wp-admin: a score out of 100, a plain-English verdict, and the list of things AI crawlers need that your site does not have yet. Then it fixes most of them for you, from inside WordPress:

• llms.txt — a Markdown summary of your site, built from your own pages and posts and served at /llms.txt. Nothing is written to disk and nothing goes stale.
• AI crawlers in robots.txt — a Content-Signal line that states your AI preferences, and, if you choose “allow AI search and assistants, block AI training”, a block for each crawler that only collects training data (GPTBot, ClaudeBot, Common Crawl and a few more). It never un-blocks a crawler: any rule you or another plugin already wrote stays in force.
• Meta description and Open Graph tags — a description, title, image and canonical address for every page, when you do not already run an SEO plugin.
• Structured data (JSON-LD) — Organization and WebSite for the site, Article for posts, again only when no SEO plugin owns it.
• agents.json — an optional card at /.well-known/agents.json pointing AI systems at your llms.txt, sitemap and feed.

The check itself takes about ten seconds and can be run again any time. The dashboard shows your latest score.

Check first, then fix

Most AI plugins write a file and hope it helps. This one looks first, from the outside, the way an AI crawler does. It tests 60 AI crawlers and scores them by what each one is for, so blocking the ones that only collect training data doesn’t cost you points. Every finding is matched to the switch that fixes it, and checking again shows whether it worked. llms.txt is one of five fixes, not the point of the plugin.

Works with your SEO plugin

If Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework or Slim SEO is active, the meta tag and structured data switches stay off so nothing is written twice. llms.txt and the robots rules still apply.

Going further

Being readable is step one. Monitor re-checks your site weekly or daily and tells you the day its verdict or its access policy changes, with the signal that moved. The Machine Readiness Audit measures every page, writes the five files for WordPress and runs an Answer Analysis of the questions your customers ask on live AI search. The check and this plugin are free.

External services

This plugin connects to crawlreadiness.com, a service operated by the plugin author, for one purpose: running the readiness check.

• What is sent: your site address (the home URL), when you press “Check this site” or “Check again”. If you enter an API key in the settings, it is sent with the request. Nothing is sent automatically or in the background.
• What comes back: the score, verdict and list of findings, which the plugin stores in one option so the page and the dashboard widget can show them.
• What the service does with it: fetches your site’s robots.txt, llms.txt, home page and agents.json from the outside, scores them, and keeps the result so the “Full report” link works.
