Read your site the way AI crawlers do, and fix what blocks them.
A free six-lesson course for site owners, web agencies and in-house marketers who want AI assistants to read, cite and recommend a site. No code needed; each lesson ends with a task done on your own site using the free scan. It ends in a 20-question test; a pass earns a certificate anyone can check.

Version 2026-11
| # | Lesson | You leave able to | Time |
|---|---|---|---|
| 1 | Reach: who is knocking | Name the crawlers that matter and tell an edge block from a robots.txt rule | 10 min |
| 2 | robots.txt, the way crawlers read it | Read groups as RFC 9309 does and spot a rule that binds the wrong agent | 15 min |
| 3 | Read: machine files that parse | Check robots.txt, llms.txt and the sitemap on both hosts | 15 min |
| 4 | Quote: one business, one record | Make name, phone and address agree on the site, in the schema and in directories | 15 min |
| 5 | Saying what AI may do | Write a Content-Signal line and know what each value means | 10 min |
| 6 | Prove it and keep it fixed | Re-scan, read a signed answer, join the registry | 10 min |
Pass the test, get a code anyone can check
20 questions, pass mark 16, drawn from a bank of 60 so two attempts differ. Three kinds of question, all answerable from the lessons: read a robots.txt excerpt and say which group an agent obeys; read a scan result and name the stage that failed; pick the Content-Signal line that matches a stated policy.
The certificate names the person, the date and the course version, and carries a verification code checked at crawlcheck.io/certified/<code>, which shows those three facts and nothing else; no student data is published. It is a statement that the person passed the test, not a statement about any site, and it says so on its face. Valid for two years, because the crawler list changes.

Agencies: certify each person who works on client sites; the code goes on a proposal or a profile and the client checks it in one click.
