Website SEO Checker: Free SEO Score for Any Site

What the website SEO checker looks at

Unlike checkers that test a single URL, this one crawls the whole site from your sitemap and links, so it finds problems that only show up across pages, such as duplicate titles, orphan pages and broken internal links.

Internal links

Orphan pages, key pages with no contextual links, articles that link nowhere, and generic anchors such as "click here".

Broken links and redirects

Internal links that return 404 or point to redirects, and redirect chains that waste crawl budget.

Titles and meta descriptions

Missing, duplicate, too long or too short titles and descriptions, page by page.

Headings and content

Missing or multiple H1s, and thin pages that are too short to rank.

Technical basics

HTTPS, robots.txt, XML sitemap errors, pages missing from the sitemap, slow server response and very heavy pages.

Indexing signals

Noindex pages, missing or conflicting canonical tags and URL formatting issues.

Structured data

Product and Article schema, pages with no structured data, Open Graph tags and the html lang attribute.

Images and mobile

Images without alt text and pages missing the mobile viewport tag.

How your SEO score is calculated

Each issue has a severity: critical (for example broken links, missing titles or H1s), warning (thin content, redirects, missing descriptions) or notice (long titles, missing canonical tags). The score weighs each issue by its severity and by the share of pages it affects, so one broken link on a 200-page site costs far less than missing titles on every page.

The report sorts issues the same way, so the top of the list is always the work that will move your score and your rankings most.

What to do with your results

Fix critical issues on your most important pages first: home, top categories or services, and best-selling products.
Add the suggested internal links. Every report includes AI-written link suggestions for orphan and weakly linked pages, with the sentence and anchor text.
Rewrite weak titles and descriptions. Keep titles between 30 and 60 characters and descriptions between 70 and 160.
Track progress. Re-check after your changes, and connect the free SEO dashboard to see clicks and rankings from Google Search Console.
