Website SEO checker: how your site looks to Google, in 30 seconds

Technical health, speed, content and AI readiness. No email required.

What the SEO checker looks at

About 30 checks in four groups — the same things I look at first when I audit a site by hand.

Server and security

HTTPS and the HTTP redirect, www vs non-www, response time, compression, security headers, mixed content.

Technical SEO

Reachable and indexable pages, robots.txt, XML sitemap, canonical tags, declared language, hreflang for multilingual sites, mobile viewport.

Content

Title tags and meta descriptions, a single H1, H2 subheadings, amount of text, internal links, image alt text, modern image formats, lazy loading.

AI readiness

Schema.org structured data, FAQ markup, Open Graph, access for AI crawlers (GPTBot, ClaudeBot, PerplexityBot) and llms.txt.

How to read the score

Above 80 the site is in good shape; 60 to 80 there is real room to improve; below 60 start from the action plan, which the checker sorts by impact.

What an automated check cannot see

A machine sees what a machine can see. It doesn't know why a competitor outranks you or which searches actually bring you customers. For that you need a person: ask for a free manual analysis or a full SEO audit. If you'd rather do it yourself, the blog has the DIY SEO check guide.

You can run the check again whenever you like: after every major change to the site, and in any case once a month. The report can be printed or saved as a PDF, so you can compare scores over time.

Frequently asked questions

Is the SEO checker really free?

Yes: no sign-up, no email, no trial limits. It's the calling card of my work.

How many pages does it check?

Up to 5 pages per site: the home page plus a sample picked from the sitemap to cover different sections, together with the domain's technical files (robots.txt, sitemap, certificate, security headers).

SEO check, SEO tester, SEO analysis: what's the difference?

They are different names for the same kind of tool: an automated check of how your site looks to Google. What changes is how deep it goes and whether it also tells you what to do: this check returns an action plan sorted by impact.

Can the check break anything on my site?

No. It reads your pages the way a visitor or Google's crawler would: it changes nothing and needs no access.
