An SEO score summarizes how well a page is set up for search engines. Ours comes only from checks we run on your live page: whether it can be indexed, whether the title and description are the right length, whether it has one clear H1, enough text, alt text, internal links, structured data, HTTPS and a mobile viewport. Every check you fail comes with a fix.
What we check
| Group | Checks |
|---|---|
| Indexing | HTTP status, noindex, canonical tag, HTTPS, redirect chains |
| Title and description | Presence, length, repeated brand names |
| Content | One H1, heading order, word count, image alt text |
| Links | Internal links, links without text |
| Social and structured data | Open Graph, Twitter/X card, JSON-LD validity |
| Technical | Mobile viewport, language, server response time, HTML size, favicon |
| Keyword (optional) | Title, H1, description, first 100 words, URL, H2s, usage |
How to raise your score
- Fix the red items first. A missing title, a noindex tag or no H1 hurt more than a long description.
- Write for the reader. A clear title, one main heading and a complete answer to the searcher's question do most of the work.
- Link your pages together. Related pages should link to each other with descriptive link text.
- Check again after changes. The score updates as soon as your page does.
Frequently Asked Questions
We read the page and run each check: indexing, title, meta description, headings, word count, image alt text, internal links, social tags, structured data, HTTPS, mobile viewport, language, server response time and HTML size, plus keyword placement if you enter a keyword. Each check has a weight. A pass counts fully, a warning counts half and a failure counts zero. The score is the share of the weighted checks the page passes.
No. The score measures whether the page itself is set up well. Rankings also depend on your content's quality and relevance, links from other sites, competition and search intent, which no single-page check can measure.
Every tool picks different checks and weights. Ours only uses things we can measure on your page right now; we do not estimate traffic or domain authority. Read the individual checks rather than comparing numbers across tools.
Yes, if the page targets one. With a keyword we also check whether it appears in the title, H1, meta description, first 100 words, URL and H2 headings, and how often it is used.
We measure how long your server takes to send the page to us, the first response only. Tools such as PageSpeed Insights measure the full page load in a browser, including images and scripts.
No. We read the page when you click the button, send the results to your browser and keep nothing. The tool is free with no sign-up; each visitor can run a limited number of checks in a short period.
