Meta Tag Analyzer
Analyze and preview your page meta tags
The Meta Tag Analyzer inspects a page's title, description, canonical, Open Graph, Twitter, robots, and related tags, then scores what it finds with a weighted checklist. Use HTML mode for draft markup or URL mode to inspect a live public page. Pasted HTML stays in your browser, while URL mode fetches returned HTML through Tool-web's server.
Paste mode stays in your browser. URL mode sends the URL to Tool-web's server, which fetches the page over HTTPS so it can be analyzed.
How to Use
- Choose HTML mode to paste markup or URL mode to fetch a live page
- Enter the HTML or public URL you want to inspect
- Click "Analyze"
- Review the weighted SEO score, extracted tags, and issue list
- Copy or download the plain-text report if you need to share it
Features
- HTML paste mode plus live URL fetch mode
- Weighted SEO score with pass/fail checks
- Extracts title, description, canonical, Open Graph, Twitter, robots, and language tags
- Flags duplicate or missing tags and title/description length issues
- Copy and download report actions
Tips for getting Meta Tag Analyzer right
- Use HTML mode before launch and URL mode after launch to catch publishing mismatches
- Cut descriptions at around 160 characters so search snippets do not truncate mid-thought
- Check the missing-tag cards as well as the score — one absent canonical can matter more than several minor warnings
- Re-run the audit after deployment to confirm the live page matches the source you intended to ship
HTML paste mode vs URL mode
| Mode | Best for | What to remember |
|---|---|---|
| HTML | Auditing a draft before deployment | Runs entirely in your browser because you paste the markup directly |
| URL | Checking what a live public page returns | Uses Tool-web's server to fetch the page HTML first |
Worked example: diagnosing a low score
Paste a page with a 73-character title, no canonical link, and no og:image. The analyzer scores the page, highlights the title-length issue, warns about the missing canonical, and lists the absent social tags so you know exactly what to fix in the head.
Real-World Use Cases

- Include primary keywords naturally in both title and description
- Add Open Graph tags for every public page on your site
- Use HTML mode before launch and URL mode after launch to compare intended markup with the live page
Common Mistakes to Avoid
- Writing meta descriptions longer than 160 characters
- Using duplicate title tags across multiple pages
- Ignoring Open Graph tags for social media visibility
- Not including target keywords in meta descriptions
- Forgetting to update meta tags when page content changes
Troubleshooting
- If tags aren't showing in search results, check for crawl blocks in robots.txt
- For social media issues, use the platform's debug tool to validate tags
- If URL mode returns unexpected markup, confirm the page isn't relying on a blocked private resource or unusual client-side rendering
- Verify canonical URLs are set correctly for duplicate content pages
- Clear social media cache after updating Open Graph tags
Frequently Asked Questions
Can I analyze any website?
What meta tags does it check?
Does URL mode store the page I fetch?
Privacy & Security
Paste mode analyzes HTML entirely in your browser. URL mode asks this site's server to fetch the page you enter so meta tags can be extracted — fetched pages are not stored, and requests are rate-limited.
