SEO Validation
Validation Report
Enter a page URL, then click Validate.
⚙️How it works
Enter an https:// page URL or paste its raw HTML. The tool analyzes the page locally using DOMParser and checks important SEO elements, including:
- Title length
- Meta description
- Canonical URL
- Keywords
- H1 and H2 headings
- Open Graph and Twitter cards
- JSON-LD structured data
- Robots meta tag
- Sitemap link
- Image alt text
Each check is marked Pass, Warn, or Fail, with an overall SEO score and recommended fixes.
🔒Privacy
The page is fetched directly in your browser whenever possible, and nothing is stored. If browser security blocks the request, the tool may use a public CORS relay to retrieve the page.
For complete privacy, paste the raw HTML instead. The HTML is then analyzed locally without being sent anywhere.
💡Tips
- Use an
https://URL for the most reliable results. - If fetching fails, paste the page’s raw HTML and run the analysis again.
- “Meta keywords present” may show a warning because Google stopped using meta keywords for ranking in 2009. This is informational, not necessarily an error.
- Fix Fail items first, then address Warn items to improve the score.
