What this meta tag analyzer does

Meta Tag Analyzer reads the markup you paste and reports what search engines and social platforms will actually see. It checks the title and description lengths, canonical link, robots directives, language, viewport, heading structure, image alt attributes, Open Graph tags, Twitter card tags and JSON-LD blocks.

Every check includes the value found and a short explanation of why it matters. The analysis is deterministic and local: there is no crawler, no URL fetch and no guesswork about what a page contains.

Why use it

  • Catch a missing or duplicated title before publishing.
  • Check that shared links have an image and description.
  • Spot heading and alt-text gaps that hurt accessibility.

How to use it

  1. 1View source and copy the full HTML, or copy the contents of the head.
  2. 2Paste it into the analyzer.
  3. 3Work through the failing checks; each one names the missing tag.

Worked examples

Missing description

Input

<title>Example</title> with no meta description

Output

Warning: no meta description; search engines may invent a snippet.

Long title

Input

A title of 85 characters

Output

Warning: likely truncated in results; aim for roughly 50–60 characters.

Common mistakes

  • Auditing a single-page app's empty HTML shell instead of the rendered DOM.
  • Assuming a present title tag is unique across the site; uniqueness needs a crawl.
  • Adding every possible tag and slowing the head; only a few matter consistently.

Frequently asked questions

Does this fetch my URL?
No. Paste the HTML. Fetching a page would need a server-side crawler, and this tool is deliberately local.
How long should a title and description be?
Titles are usually around 50–60 characters and descriptions around 140–160, but Google rewrites both. The limits are guidance, not rules.
Will fixing these tags guarantee rankings?
No. Metadata affects how a page is represented and clicked, not whether it deserves to rank. Content, links and technical health matter more.
