Frequently asked questions

What is a meta tag analyzer?

A meta tag analyzer fetches a webpage and reads the HTML head section to extract all meta tags — title, description, Open Graph, Twitter Card, robots directives, and more. It lets you verify what search engines and social platforms see for your page.

Can it analyze any URL?

It can analyze any publicly accessible URL. Password-protected pages, pages behind login forms, or those that block server-side requests may not return full data.

How is the SEO score calculated?

The score is based on presence and quality of key tags: title, meta description, canonical URL, viewport, Open Graph tags, and Twitter Card. Each contributes a weighted amount to the total score out of 100.

What is the ideal meta description length?

Google typically displays 120–160 characters of a meta description. Keeping yours in this range helps ensure it is not truncated in search results.

Does this tool store the URLs I analyze?

No. The analysis is performed on-demand and the results are not stored anywhere. Each request is independent and private.

Do I need to install anything or sign up?

No. The Meta Tag Analyzer runs in your browser and needs no extension, download or account — just paste a URL and analyze.

What meta tags does it check?

It reports the title and meta description with length guidance, the canonical URL, robots directive, viewport and charset, plus the Open Graph and Twitter Card tags used for social sharing previews.

Why do some tags show as missing?

Either the page genuinely does not include them, or it blocks server-side fetches so the full HTML head could not be read. Public, directly-accessible pages return the most complete results.
