Meta Tag Analyzer

Available

Analyze a web page’s SEO metadata: title, meta description, canonical URL, robots directives, hreflang, viewport and every other meta tag, with length checks and a search-result preview.

Analyze a page

The HTML is read as the server delivers it; tags added later by JavaScript are not seen.

Metadata report

Fetch a page or paste its HTML to see its title, description, canonical, robots directives and all meta tags.

How it works

The page’s HTML is parsed (never executed) and its metadata is extracted: title, meta tags, link relations such as canonical and alternate, and the html lang attribute. Lengths and common mistakes are checked. Paste mode analyzes HTML entirely in your browser; fetching a live page needs the NetTools server.

What matters most

  • Title: unique per page, describes the content; shown as the headline in search results and browser tabs.
  • Meta description: not a ranking factor, but often used as the snippet, so it affects clicks.
  • Canonical: tells search engines which URL to index when the same content is reachable at several addresses.
  • Robots: noindex keeps a page out of search results. It only works if crawlers may fetch the page (not blocked in robots.txt).

Safeguards & responsible use

  • Fetches only public http(s) pages with the same SSRF protection as the Redirect Checker, reading at most the first 2 MB of HTML.
  • Scripts are never executed; pasted HTML is parsed inertly in your browser and not uploaded.
  • Per-client rate limits; pages are not stored.

Frequently asked questions

How long should a title and description be?

Search engines truncate by pixel width, so there is no exact limit. Titles of roughly 30–60 characters and descriptions of 70–160 characters usually display in full.

Does the meta keywords tag help?

No. Major search engines ignore it.

Why does the analyzer show different tags than my browser?

It reads the HTML as delivered by the server. Tags added later by JavaScript are not seen, and some sites serve different HTML to automated requests.
