On-Page SEO Audit Tool
Run a free on-page SEO audit and beat your competitors. Enter your page and target keyword — the tool reads the live HTML, runs 75+ checks, tests links live, previews your Google result and compares you with up to 3 competitors. 100% free. No sign-up. Real data only.
Page blocks bots? Paste its HTML source instead
Open your page, press Ctrl+U (Cmd+Option+U on Mac), select all, copy and paste here. The URL above is still used for link and URL checks.
Only public websites are checked. Private/internal addresses are blocked for safety.
How to use
- Enter the page URL you want to audit and the keyword you want it to rank for.
- Optionally add up to 3 competitor pages that currently rank above you.
- Click Run Free Audit. You get a score out of 100, a "fix these first" list, the full 75+ check report, a Google result preview and — if you added competitors — a side-by-side comparison with the topics they cover that you are missing.
- Download the report as CSV, or save it as a PDF for clients and records.
What the audit checks
Meta tags and URL structure, heading order and keyword placement, content length, keyword density and readability, internal and external links (tested live, including broken and redirecting links), image alt text, formats and sizes, technical health (indexability, robots.txt, sitemap, canonical, HTTPS, compression, speed of the HTML download), AI-search readiness (AI crawler access, llms.txt, FAQ schema), structured data and trust signals, and social sharing tags.
The score measures on-page setup only. Rankings also depend on backlinks, domain authority and search intent — but on-page is the part fully in your control, and this tool shows you exactly where you stand against the pages beating you.
Frequently asked questions
What does the On-Page SEO Audit Tool check?
It runs 75+ on-page checks: title and meta tags, headings, keyword placement, content and readability, links (tested live), images, technical and indexing settings, AI-search readiness, structured data and social sharing tags — and scores the page out of 100.
Can I compare my page with competitors?
Yes. Add up to 3 competitor pages and you will see a side-by-side comparison of scores, keyword placement, content depth and structure, plus the topics and sections competitors cover that your page does not.
Is the On-Page SEO Audit Tool free to use?
Yes. It is completely free, like every tool on SEO Tools by metacalculator.org. There is no sign-up, no watermark and no hidden limits.
What if a page blocks automated checks?
Some sites block bots. Open the page in your browser, press Ctrl+U to view its source, copy the HTML and paste it into the tool — the audit then runs on the pasted source instead.
