Tip: if you paste only <head>, the results are still accurate for most checks.

How to use

      
Use it to audit the meta tags of a page when you have the HTML source.
  1. Open the page in your browser and view source.
  2. Copy the full HTML (or at least the <head> section).
  3. Paste it into the input box and click Check meta tags.
  4. Review warnings (missing/duplicate tags, length checks, robots/canonical issues) and copy the report if needed.

FAQ

    
Can I paste only the <head> section instead of full HTML?
Yes. Most checks (title, meta description, robots, canonical, OG/Twitter) work fine with just <head>.
Does this tool fetch a URL if I paste a link?
No. It doesn’t make network requests; it only analyzes the HTML you paste.
What title and description lengths should I aim for?
As a rough guideline, titles often work best around 30–60 characters and descriptions around 70–160, but SERP display can vary.
Why does it warn about a relative canonical URL?
Relative canonicals can work, but absolute URLs reduce ambiguity and are generally safer across tools and crawlers.
If robots is missing, is that bad?
Not necessarily. Many sites rely on default indexing behavior unless they need to block pages with noindex.
What does “multiple meta descriptions found” mean?
It means the HTML contains more than one meta name="description". Search engines may ignore duplicates or pick one unpredictably.
Does this validate correctness against Google rules?
No. It’s a practical checker that extracts tags and flags common issues; it’s not a formal standards validator.
