Free SEO checker: your site as Google and AI assistants read it

What the checker reads

The checker visits your site the way a crawler does. It reads your homepage and 5 pages from your sitemap, and checks that up to 50 of your sitemap addresses still answer. Nothing is installed and nobody needs your password: it sees what any visitor, human or machine, can see.

What it finds is scored against 106 published checks, the same rubric our paid audit uses. Each check traces back to a rule Google, an AI company or a web standard has written down, and the rubric page lists every one of them with its source. A score you cannot trace is an opinion; this one you can audit yourself.

Two scores, because two machines are reading

Most free SEO checkers give you one number. We give you two, and we never add them together.

The Search SEO score asks whether Google can crawl, index and understand your pages. It covers:

• Crawlability (M1)
• Indexability (M2)
• Site health (M3)
• Rendering / JS dependency (M4)
• Structured data (M5)
• On-page & meta (M7)
• Social cards (M8)
• Images / media (M9)
• Internal linking & semantics (M10)
• Freshness (M13)
• Core Web Vitals / performance (M15)
• E-E-A-T / authority (M16)
• Sitemaps & discovery (M17)
• International / hreflang (M20)

The AI visibility score asks whether an AI assistant can reach your pages and lift a clear answer from them. It covers:

• Rendering / JS dependency (M4)
• Structured data (M5)
• Entity / knowledge graph (M6)
• Images / media (M9)
• Answer extractability (M11)
• Fact density / original data (M12)
• Freshness (M13)
• AI crawler access (M14)
• E-E-A-T / authority (M16)
• llms.txt (M21)

The two drift apart more often than owners expect. A site can rank well and still block the crawlers AI assistants use, or bury its prices and opening hours in images no machine reads. What people now call "AI SEO" is mostly the second score: can an AI crawler get in, is the answer stated plainly enough to quote, and does the site say clearly who stands behind it.

What the result tells you

You get both scores, from 0 to 100, and the issues the scan found, each with what it means for the customers you reach: a page Google cannot index is a page no searcher meets; an AI crawler turned away at the door is an assistant that answers without you.

The result names the problem and its consequence. The fix itself, written for your site, ranked by impact and effort, and proven by a re-scan once it is applied, is the work we do in the audit.

What no checker can tell you

No checker can tell you where you will rank, and no honest one will try. Nobody outside Google controls rankings, and nobody controls what an AI assistant says. A strong score means your site is easy to find, read and quote. Whether you are chosen still depends on what your competitors publish and on what customers ask.

The free scan also reads a sample. A broken page deep in a large site waits for the paid audit, which reads up to 300 pages. And the checks that read the words themselves, answer blocks and fact density, are built for English today: on a Traditional Chinese page their findings are less reliable, while crawler access, structure and speed work in any language.

After the scan

If the scores are what you hoped, keep the link and check again after your next redesign. If they are not, the audit gives you every finding on your own site with its evidence, and the ten fixes that matter most in the order to do them, in 3 business days. You can read a real report on our own site before you decide.

Questions about the free checker

Is the SEO checker really free?

Yes. There is no sign-up, no card and no trial that turns into a subscription. You type an address and get two scores. We earn our living from the audit and the work after it, for the owners who want their issues fixed.

Do you keep data about my site?

The free scan keeps no raw files: they are deleted once the scores are computed. We keep a short scan record, the domain and the time, to apply scan limits and stop abuse. The privacy page lists each item and how long it is kept.

Does it work on WordPress, Wix, Shopify or Squarespace?

Yes. The checker reads the public website, the same pages your customers see, so the platform underneath does not matter. Some platforms limit what an owner can change, and our install guides say per platform what can be fixed and how.

How is this different from other free SEO checkers?

Most stop at Google. Ours scores the same site a second time for AI assistants: crawler access, answers stated plainly enough to quote, and a clear owner behind the site. Every check is published with the rule it comes from.

Will a better score bring more customers?

It removes the reasons a machine cannot find or read you. It cannot make anyone choose you, and we never promise rankings, traffic or AI mentions. What we promise is measurable: each fix we write is re-scanned to prove it landed.
