Website SEO Score Checker

Enter a web address to run the check

  • Checks one page per run; it doesn't crawl the site.
  • No result is shown if the page can't be fetched.

How to use the website SEO score checker

  1. 1Enter the page address and press Audit page.
  2. 2Read the Checklist score and the counts of passes, warnings and problems.
  3. 3Work through Fix first: problems come before warnings, heaviest checks first.
  4. 4Open Full checklist with evidence to see what was found for every check, such as the exact title text and its width.

Example: the sample page (illustrative URL)

Input
https://www.example.com/baking/sourdough-starter/  (the tool's sample HTML, served with Brotli, 310 ms TTFB)
Output
Checklist score 82/100 (71 of 87 points) · 15 passed · 5 warnings · 1 problem · 5 notes

Fix first:
Problem  og:image: relative URL “/images/starter.jpg”
Warning  Title tag: ~724 px, likely truncated
Warning  Meta description: 46 characters, short
Warning  Visible text: 27 words
Warning  Heading structure: jumps from H1 to H3; empty H2
Warning  Image alt attributes: 1 of 1 image has no alt

Computed by the tool's checklist on the sample HTML with the response details shown. A real URL's result depends on what its server returns.

What the audit checks

Our server requests the page as a crawler would, then checks what it received:

  • Indexability: HTTP status, redirects, robots meta, X-Robots-Tag, canonical.
  • Title and description: present, unique in the page, estimated pixel width.
  • Content and headings: H1, heading order, amount of visible text.
  • Links and images: internal links, empty links, alt attributes, image dimensions.
  • Structured data: JSON-LD present and parseable.
  • Mobile and document: viewport, lang, charset, favicon.
  • Speed basics: server response time, compression, HTTPS.
  • Social sharing: Open Graph and X card tags.

Each check shows its evidence, so you can verify it yourself.

How the score is calculated

Every scored check has a weight. A pass earns the full weight, a warning half, a problem nothing; notes aren't scored. Score = points earned ÷ points available × 100.

WeightChecks
10HTTP status, robots meta tag, X-Robots-Tag (when it blocks), title tag
6Meta description, viewport
5H1
4Canonical, visible text, HTTPS
3Heading structure, links, image alt, structured data, server response time, og:image, redirect chains of 2+ hops
2Single title, page language, HTML compression, empty links, og:title, og:description
1Single description, charset, favicon, twitter:card

The score summarises this checklist. It isn't a Google metric and doesn't predict rankings.

Indexability: robots, canonical, status

These checks carry the most weight because any one of them can keep a page out of search entirely: a non-200 status, a noindex in the HTML or in an X-Robots-Tag header, or a canonical pointing somewhere else. If the address redirects, the audit runs on the final URL and lists the hops; two or more redirects in a row cost points. If the page can't be fetched at all, the tool shows the error and no score, rather than a misleading number.

Content and headings

The audit counts the words in the HTML body and flags pages under 150 words, a point where the HTML may be a JavaScript shell or a thin page. That isn't a Google rule; there's no minimum word count. It also checks for one descriptive H1 and headings that go down one level at a time. For the full outline use the heading checker, and for titles and social tags in more detail, the meta tags analyzer.

Prioritising fixes

Fix first lists problems before warnings, heaviest first. A reasonable order of work:

  1. Anything that blocks indexing (status, noindex, canonical).
  2. Title and description, which shape how the result looks.
  3. Headings, content and internal links.
  4. Structured data, images and social tags.
  5. Speed: the audit only measures the HTML response; run the website speed test for Core Web Vitals.

Then validate structured data with the schema markup validator.

What happens to the address I enter?

To check a URL, our server requests the address you enter and returns the result to you. We don't store the pages we fetch or keep a list of the addresses you check. Like any website, our hosting provider keeps short-lived technical request logs for security. See the privacy policy.

Questions about the website SEO score checker

Is an SEO score a Google ranking factor?

No. Google doesn't compute or use any SEO score. This score summarises our checklist so you can track fixes; the individual checks and their evidence are what matter.

Why do SEO checkers give different scores?

Each tool chooses its own checks and weights. Ours are published on this page, so you can see exactly why a page scored what it did.

Does it crawl my whole site?

No. It audits the one URL you enter. Run it on your most important templates (homepage, a category, a product or article) to find site-wide issues.
