Key takeaways

  • On-page SEO decides whether a search engine can understand and accurately display your page. It does not create authority you have not earned.
  • The two highest-leverage fixes are the page title and the meta description, because they decide whether a searcher clicks.
  • A score out of 100 is a way of ordering problems, not a measurement. Every tool calculates it differently.
  • Checking one page is usually enough to diagnose a sitewide problem. Metadata defects rarely affect the homepage alone.
  • The free result focuses on the homepage. It does not verify backlinks, rankings or whether Google has indexed every page.

What does a free SEO checker check?

This one checks five things on the page you submit:

Page title
Missing, duplicated, truncated past what Google shows, or still a theme default like "Home".
Meta description
Missing, over length, duplicated sitewide, or describing the company instead of giving a reason to click.
Heading structure
No H1, more than one H1, or headings used for styling rather than structure.
Commercial intent
Whether the page uses words buyers type, or only what the business calls itself internally.
Crawlable content
Whether your visible copy is in the served HTML, or only appears after JavaScript runs.

How do I check my website for SEO?

  1. 1

    Run the free check

    Open the On-Page SEO Tool above and enter your domain there. The check reports measured homepage findings.

  2. 2

    Read your own search results

    Search Google for site:yourdomain.co.uk. The titles and descriptions listed there are what you actually compete with.

  3. 3

    Fix titles and descriptions first

    Rewrite them so each one names the page subject and gives a reason to click. This is the highest-leverage change available.

  4. 4

    Repeat across the site

    Apply the same logic to every page. Above roughly twenty pages, this stops being viable by hand.

Found problems on your homepage?

The paid audit checks more pages and prepares recommendations you can act on. See current coverage and pricing in the On-Page SEO Tool.

What is a good SEO score?

There is no standard. Every checker calculates its score differently, so a number from one tool cannot be compared with another. Treat it as a way of ordering problems.

  • A site scoring 92 can still be invisible in search.
  • A site scoring 60 can be taking orders all day.
  • What matters is which pages carry which defects, and whether anyone searches for those pages.

Frequently asked questions

Is this SEO checker free?

Yes. Follow the link to the On-Page SEO Tool and enter your domain there. You can see an initial finding before entering an email to reveal the rest. No card or account is required.

Why do you ask for an email address?

The On-Page SEO Tool asks for an email to reveal the full free result and deliver the requested result. Marketing emails are an optional choice.

How many pages does the free check cover?

The free result focuses on your homepage. The paid audit covers more pages according to the plan you choose in the On-Page SEO Tool.

What does this checker not do?

It does not check backlinks, domain authority or rankings. A mobile speed score may be available in the homepage check, but it is not a full Core Web Vitals diagnosis.

Does a good score mean my site will rank?

No. On-page SEO removes a handicap. Ranking also depends on search demand, competition and your site’s authority.

Which website platforms does it work with?

All of them. The check reads your page over the public web, so it works on WordPress, Shopify, Squarespace, Wix, Webflow, Drupal, Adobe Experience Manager or a custom build. Nothing to install.
