What does this tool check?
What problems does this find?
The issues this check most often surfaces on real sites:
- Missing or duplicate title tags and meta descriptions
- Broken heading hierarchy or multiple H1s on a page
- Missing canonical tags, Open Graph, or structured data
What do I do after the check is complete?
These are the basic SEO details on your page — the title search engines show, the description, the headings, and more. Here's what's set up well and what needs attention.
- 1
Start with the pages that matter commercially
Work down the list in order of how much you care about the page, not how bad the number looks. A flagged page nobody needs to find is not worth an hour of your time.
- 2
Fix the cause, not the symptom
Most findings here are structural: a page is unreachable, under-linked, or competing with another page. Adding one contextual link from a strong, relevant page usually fixes more than editing the page itself.
- 3
Re-run this check to confirm the fix landed
The check is free and takes a couple of minutes. Re-crawling after a change is the only way to know it worked — and the full audit tracks the difference between crawls for you.
Why on page seo checker matters for SEO
On-page elements — title tags, meta descriptions, headings, canonicals, and structured data — control how your pages appear in search results and how clearly engines understand what each page is about. They're the foundation every other SEO effort builds on: get them wrong and even great content and strong links underperform. The good news is they're quick to fix and entirely within your control, which makes on-page issues some of the highest-leverage problems to clear first. This check focuses your main page, while a full account audits every page so nothing slips through.

What is on-page SEO?
On-page SEO covers the elements on a page you can optimise directly: the title tag, meta description, headings, URL, canonical tag, social meta, structured data, and content. Getting these right helps search engines understand and rank your pages.
Does this check the whole site or one page?
The free check focuses on your primary page's on-page elements while crawling your site for structure. A free account runs the full on-page audit across every page, alongside the internal-link and authority analysis that sets RankForge apart.
What does the full audit add?
The free check shows what passes and fails. A free account unlocks the exact fix for each issue, every page audited, a client-ready PDF, and weekly re-crawls.
