Free SEO checker

The on-page basics that decide whether Google understands a page — checked on your homepage and on pages sampled from your sitemap, where duplicate titles and missing headings hide.

About a minute. No signup for the summary.

What this check looks at

Page titlePresent, and a length that is not cut off in search results.
Meta descriptionPresent, not duplicated, a length search engines show in full.
Main headingExactly one H1, and on the subpages we sample too.
Canonical linkSo duplicate addresses of the same page do not compete with each other.
robots.txtPresent, and not blocking what should be found.
sitemap.xmlPresent and readable; we also sample pages from it.
Structured dataJSON-LD that lets search engines show your product, organisation or FAQ as rich results.
Share previewOpen Graph title, description and image — what LinkedIn, Slack and X show when someone shares your link.
Page languageThe lang attribute search engines and screen readers rely on.
Image alt textsImages without a text alternative — invisible to screen readers and image search.
Amount of textEnough words for a search engine to understand what the page is about.
Mobile viewportThe tag without which phones render the desktop page, tiny.
SpeedHow fast your server answers, and Google PageSpeed Insights loading the page on a throttled mid-range phone and on a desktop: both scores, Core Web Vitals and the biggest wins in seconds saved.

Plus the rest of the 30+ checks — every scan runs all of them.

Why it matters

An SEO tool that reads only your homepage misses the most common problem: twenty pages sharing one title, or product pages without a heading. We take pages from your sitemap and compare them with each other.

Speed is part of it too — Core Web Vitals are a ranking signal, so the same scan asks Google PageSpeed for the phone and desktop numbers.

What it does not do

It does not count backlinks or estimate keyword rankings — that needs a crawler of the whole web. It tells you what on your own pages keeps them from ranking.

Questions

Does the SEO checker look at more than my homepage?

Yes. It reads your sitemap and samples subpages, looking for duplicate titles and descriptions, missing H1 headings and addresses that no longer answer.

Will it tell me my Google ranking?

No. Rankings and backlinks need data from crawling the whole web. This check covers what you control on your own pages: titles, descriptions, headings, canonical links, sitemap, robots.txt, structured data and speed.

Is it free?

Yes, the summary needs no signup. The full report with every fix asks for an email once.
