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.

1.0.3

• "Allow AI search and assistants, block AI training" also blocks MistralAI-Training, Mistral's training crawler, so the list matches the training-only crawlers the Crawl Readiness check leaves out of its score.
• The description says what the plugin is for: a site set up for AI the way you intend. The check covers 60 AI crawlers.

1.0.2

• The robots.txt switch no longer gives each AI crawler an "Allow: /" rule of its own. A crawler with its own rule ignores the site's "User-agent: *" rules, so those lines let AI crawlers into /wp-admin/ and into anything else those rules keep out, and could un-block a crawler the owner had blocked. AI crawlers now follow the site's own rules; "block AI training" still blocks the training-only crawlers by name.
• "Allow AI crawlers" mode leaves ai-train out of the Content-Signal line instead of writing ai-train=yes, so it no longer grants training on the owner's behalf.
• A blocked-crawler finding no longer points at the robots switch.

1.0.1

• The closing card and this readme describe Monitor and the Machine Readiness Audit; the old LLM Monitor pitch is gone. No functional change.

1.0.0

• First release: the check, llms.txt, AI crawler rules with a Content-Signal line, meta and Open Graph tags, JSON-LD, agents.json, dashboard widget.
