This agentic SEO checker fetches your site the way AI agents such as ChatGPT and Perplexity do, without running JavaScript, and reports what they can and cannot read. It looks at your homepage, robots.txt, llms.txt, your sitemap and your about, contact, privacy and pricing pages, then gives a score out of 100 with a fix for each gap. It is free and needs no signup.
How to use the agentic SEO checker
- 1Type your site's address in Website to check, such as example.com. The checker reads the whole domain, so a page address works too.
- 2Press Check, or hit Enter, and wait a few seconds while it fetches your pages.
- 3Read the grade and the Essential and Recommended counts beside it. Essential checks carry 80 of the 100 points.
- 4Work down the list. Each check that failed or passed in part says what the checker found and, under What to do, how to fix it.
- 5Press Copy fix prompt to copy the open checks as one set of instructions, then paste them into a coding agent or send them to whoever looks after your site.
- 6Make the fixes, publish them, then check the site again to see the score move.
When to use it
- You want to know whether ChatGPT can even open your pages before you worry about why it suggests other businesses.
- You moved your site to a page builder or a JavaScript framework and want to know if AI agents can still read it.
- Your developer asks what to change for AI search and you want a list they can work through.
- You added an llms.txt file or structured data and want to confirm agents can find and read it.

- Fail: No navigator.modelContext or document.modelContext tools and no toolname forms in the homepage or its 8 script bundles.
Every essential check passes: the AI agents get the full homepage, robots.txt lets them in, the text loads without JavaScript and missing pages answer 404. All four open items are recommended, so together they cost 2 points. The site is read as a software product because it declares SoftwareApplication structured data, which is why the API, MCP and WebMCP checks run at all; a business site is never graded on them. The address gap is a fact only the owner can supply, and the fix prompt says so rather than inventing one.
How the score is built
| Part | Points | What it checks |
|---|---|---|
| Essential | 80, shared equally | AI agents reach the full homepage, robots.txt lets AI search agents in, the content loads without JavaScript, missing pages answer 404, no redirect tricks, landmarks and headings, real buttons, links and labelled form fields, and real contact details. Software products also need an OpenAPI spec and an MCP server. |
| Recommended | 20, shared equally | llms.txt and its links, when-to-use guidance, markdown on request, structured data about the business, its profiles and its address, canonical and share tags, prices an agent can find, about, contact and privacy pages, a dated sitemap and pages short enough to read in one go. |
| Bonus | Up to 5 | Signals that help when present and cost nothing when missing, such as a Link header, a markdown copy of the homepage and, for software products, agent and MCP discovery files. |
Grades run A+ at 97 and up, A from 90, B from 80, C from 70, D from 60 and F below that. A check the checker could not measure, such as a request your server refused, shows as Not measured and leaves the score.
