Website SEO Analyzer

Enter any page URL and this free website SEO analyzer fetches the live page and audits its on-page fundamentals: an overall SEO score out of 100, a pass/fix checklist covering the title tag and its length, the meta description, the H1 and heading structure, image alt-text coverage, internal and external link counts, canonical and viewport tags, HTTPS, word count and structured data — plus the raw numbers behind every check. It is an honest first-pass audit: the same checks an SEO runs in the first five minutes on a new page, automated. Run it on your own pages before publishing, or on a competitor's page to see what they are doing right.

How to use this tool

  1. Paste any public page URL.
  2. Click Analyze this page.
  3. Read the score and the PASS / FIX checklist.
  4. Work through the fixes in priority order, then re-run.

Worked example

A local services page scores 62: no meta description, three H1s and half its images missing alt text — a one-hour fix list, in order, from a ten-second check.

Frequently asked questions

What does the SEO score actually measure?

Thirteen on-page checks, weighted by importance: title presence and display length, meta description presence and length, exactly one H1, presence of H2 structure, image alt coverage, canonical tag, mobile viewport, HTTPS, HTML language, Open Graph tags, structured data, page size, and a minimum body word count. It deliberately measures only what can be verified from the page itself. Backlinks, site authority, Core Web Vitals timings and keyword rankings need other tools — a 100 here means "technically well-built page", not "guaranteed to rank".

What is a good score, and what should I fix first?

Above 85 is a well-finished page; 60–84 is typical of real-world pages with a few fixable gaps; below 60 usually means fundamentals are missing (no description, multiple H1s, no alt text). Fix in this order: anything blocking (noindex is checked elsewhere in the meta checker, HTTPS), then title and H1 (the strongest on-page signals), then description and canonical, then alt text and structure. The checklist output is already sorted roughly in that priority order.

Why do image alt coverage and headings matter so much?

Alt text is how search engines "see" images: it drives image-search traffic, supports the page's topical relevance, and is an accessibility requirement for screen-reader users. Heading structure is the page's outline — one H1 stating the topic, H2s dividing it into sections — which helps engines understand what the page covers and powers features like jump links in results. Both are cheap to fix and commonly neglected, which is why the analyzer weights them visibly.

Can this analyzer check my whole website?

It analyzes one page at a time — deliberately, because on-page problems are page-specific: the homepage passing says nothing about a neglected services page. Check your homepage, your main money pages and any page you are about to promote. For a full-site crawl with hundreds of URLs you need a desktop crawler; for the pages that actually earn money, this focused check plus the fixes it lists is the practical 95%.
