What on-page SEO analysis checks

On-page SEO analysis looks at the signals inside a single page that tell Google and AI engines what it is about and whether it deserves to rank. This tool scores 21 of them across five groups: titles and descriptions, headings and content, indexing and canonical, structured data and social tags, and links and speed. Every failed check comes with the fix.

How to use this SEO website tool

  1. Paste the full URL of one page, not just the domain. Start with your homepage or your top money page.
  2. Read the score and band. Anything below 65 has core gaps worth fixing this week.
  3. Work the failed checks top to bottom. Title, H1, canonical, and noindex problems matter most.
  4. Re-run after publishing. Results refresh every 6 hours per URL.

FAQ

What is onpage SEO analysis?

It is the review of elements on the page itself, such as title tag, meta description, headings, content depth, images, canonical, and structured data, to confirm search engines can understand and rank the page. Off-page SEO covers links and mentions from other sites.

Is this a free SEO analysis tool?

Yes. Every check and every fix is shown without an email address or account. It runs on the same page rubric SEMPITE uses inside paid audits, limited to 20 pages per day per visitor to keep it fast for everyone.

How is this different from a full website audit?

This scores one page's on-page signals. The SEMPITE Brand Audit covers the whole presence: site-wide crawl, Google Business Profile, backlinks, competitors, and whether ChatGPT and Google AI mention you, with a prioritized plan.

Why did a page with good content score low?

Usually a missing canonical, a duplicated H1, no structured data, or an accidental noindex. Those are quick fixes with outsized impact, which is why the rubric weights them heavily.

Does it execute JavaScript?

No. It reads the HTML your server sends, which is also what many crawlers and AI engines see first. If your titles and content only appear after JavaScript runs, that is a finding worth fixing.
