What does the free check test?
Nine things, all of them verifiable by hand: title, description, main heading, sitemap, indexability, canonical URL, live AI search access, business markup, and content without JavaScript.
Every one is something you could confirm yourself with a terminal and ten minutes. Nothing is estimated and nothing is a proprietary score — it's the same code that runs a paid client audit.
- Title and description
- — Whether they exist, and whether they're the length that survives being shown in a result.
- One H1
- — Exactly one main heading. Zero is common on template sites; four is common on page builders.
- Sitemap
- — Whether a usable XML sitemap exists and returns pages rather than an error.
- AI crawler access
- — Whether robots.txt blocks OAI-SearchBot, Claude-SearchBot or PerplexityBot. Training crawlers are not scored.
- Indexability and canonical
- — Whether the page accidentally says noindex, and whether its canonical points back to the URL being checked.
- LocalBusiness markup
- — Whether your address, hours and phone are present as structured data.
- Content without JavaScript
- — How much of the page is in the HTML before scripts run, which is all some crawlers ever see.
