What Is the SEO Health Score?

It runs the main on-page checks in one go - title, meta description, canonical, headings, structured data and image alt text - and combines them into a score with a list of fixes.

When to Use It

For a quick on-page SEO review of an important page.
To compare pages before and after changes.

How to Use It

Enter the page URL.
Work through the recommendations, starting with missing items.

Understanding the Result

A high score means the on-page basics are in place. Rankings also depend on content quality, links, speed and search intent, which on-page checks cannot measure.

Limitations

One page is checked at a time. Each item has its own detailed checker in this category.

Frequently Asked Questions

This focuses specifically on on-page SEO fundamentals (title, meta description, canonical, headings, structured data, image alt coverage); the Performance Health Score instead evaluates loading speed and technical infrastructure factors - both contribute to overall search visibility in different ways.

Missing or poorly-optimized title/meta description tags and images missing alt text are among the most frequently found issues, since they're easy to overlook, especially on pages generated automatically by a CMS template.

No - on-page fundamentals are necessary groundwork, but rankings are also heavily influenced by content quality, backlink profile, and competition for the specific keywords being targeted, none of which this on-page check evaluates.

Prioritizing the highest-impact items first (missing title/meta description, missing H1) generally makes sense, but addressing the full list over time genuinely does compound into a stronger overall on-page foundation.

Re-checking after any significant content update, template change, or CMS migration is good practice, since any of those can inadvertently introduce or remove elements this score depends on.
