Free tools Run on your server, not mine agentforgepro.com

Plugins that check your site from inside it.

Every “AI visibility checker” runs from someone else's servers. That is a problem: when I measured fifty well-known brands, twelve of them refused my machine outright — not the crawlers, everything, including a plain browser. A remote scanner cannot measure those sites and will report a number anyway.

A plugin running on your own server, fetching your own pages, is never mistaken for a scraper. That is the whole idea.

AI Crawler Audit — WordPress

Can ChatGPT, Perplexity and Claude actually read your site?

Most tools read your robots.txt and stop there. That misses a failure they cannot see: your robots.txt says a crawler is welcome, and your CDN or a security plugin returns 403 to that same crawler anyway. Nothing warns you.

This plugin checks both. It fetches your home page once as each of eight crawlers and once as an ordinary browser as a control. If the browser gets 200 and a crawler gets 403 in the same minute from the same server, the block is in front of your site and editing robots.txt will not fix it.

Free, GPLv2 or later, no account, no API key, no telemetry. Every network request it makes goes to your own site and nowhere else — the source is 1,400 lines and the network calls are all in one file, so you can check that yourself.

What it reports

Findings are ordered worst first, and each one carries the raw measurement and a specific fix. There is a plain-text report at the bottom you can copy and hand to whoever maintains the site.

Installing it

In WordPress: Plugins → Add New → Upload Plugin, choose the zip, activate, then Tools → AI Crawler Audit and press the button. It takes up to a minute, because it makes about a dozen requests to your own site.

Two honest notes before you install it

This build does not update itself. A plugin installed from a zip has no update channel, so if I fix something you will not get it automatically. It is submitted to the WordPress.org plugin directory and is in the review queue; when it is listed, install it from there instead and updates arrive normally. I would rather say that than have you find out later.

Requires WordPress 6.0 and PHP 7.4 or newer. Tested on WordPress 7.1. If your host blocks outbound requests from your site back to itself, the live crawler checks cannot run and the plugin will tell you so rather than guessing.

Why these exist

I sell audits. A free tool that finds a real problem on your site is a better argument for that than any sales page, and if it finds nothing then you have learned something useful and cost me twenty minutes of compute.

The measurements behind the design are published: Readable, Not Quotable — fifty brands, what fraction actually block crawlers, and the much larger fraction that publish nothing a machine can quote.

Coming next

A Shopify version of the same engine is built and installs into a store. It is not listed yet. If you run a Shopify store and want to try it before it is, write to me.

I will not put anything on this page that promises to get you recommended by an AI. Nobody can honestly promise that — what gets a brand named is mentions across the web it already trusts, which is earned rather than installed. What a plugin can do is make you easier to read and easier to quote. That is real, and it is a different claim.
