Meta Tag Analyzer

Paste page HTML to extract and audit the title tag, meta description, robots, canonical, viewport, Open Graph and Twitter tags with length checks. Local only.

What is the Meta Tag Analyzer?

The Meta Tag Analyzer reads pasted page source and lays out every SEO-relevant tag in one table: title, meta description, robots directives, canonical URL, viewport, charset, html lang, plus the full set of Open Graph and Twitter Card tags.

  • Extracts title, description, robots, canonical, viewport, charset and lang
  • Full Open Graph and Twitter Card tag listing
  • Character-length checks against practical SERP limits
  • Missing-tag warnings for the elements that cost traffic
  • Works with full pages or just the <head> block
  • 100% client-side — paste source, nothing fetched or uploaded

How to use the Meta Tag Analyzer

  1. 1

    Open your page in a browser and view its source (Ctrl+U or Cmd+Option+U).

  2. 2

    Copy the HTML — the <head> section is enough — and paste it here.

  3. 3

    Scan the table: green rows are fine, amber rows need attention, red rows are missing.

  4. 4

    Fix the flagged tags in your template and re-paste to verify.

About the Meta Tag Analyzer

The Meta Tag Analyzer reads pasted page source and lays out every SEO-relevant tag in one table: title, meta description, robots directives, canonical URL, viewport, charset, html lang, plus the full set of Open Graph and Twitter Card tags. Each row gets a status — present and healthy, too long, too short, or missing entirely.

Length checks use the ranges that matter in practice: roughly 50–60 characters for titles and 120–160 for meta descriptions before search engines truncate or rewrite them. Missing-tag warnings cover the elements that cost real traffic when forgotten, like the canonical and the description.

Paste the HTML from view-source — this analyzer works on pasted markup only and never fetches a live URL. Everything runs 100% locally in your browser, so staging pages and unreleased templates are safe to check; nothing is uploaded.

Frequently asked questions

What meta tags matter most for SEO?

The title tag and meta description drive your search snippet; the canonical prevents duplicate-content dilution; robots controls indexing; and viewport is required for mobile-friendliness. Open Graph and Twitter tags do not affect rankings but control how links look when shared, which affects clicks.

How long should my title tag and meta description be?

Titles display in full up to roughly 50–60 characters, descriptions up to roughly 120–160 — beyond that engines truncate by pixel width. This analyzer flags lengths outside those ranges; for exact pixel measurement use our dedicated title and description length checkers.

Does Google still use the meta keywords tag?

No — Google has ignored meta keywords since 2009, and Bing treats it as a spam signal at worst. If the analyzer finds one on your page, it is safe (and slightly tidying) to delete it. Time is better spent on the title and description.

What does a missing canonical tag mean?

Without a canonical, search engines pick which URL variant to index when duplicates exist — with parameters, trailing slashes or www differences all counting as variants. A self-referencing canonical on every page is a cheap insurance policy and this tool warns when none is present.

Why paste HTML instead of entering a URL?

This analyzer has no server and browsers cannot read third-party sites, so a URL fetch is impossible by design. Pasting view-source output is quick and lets you audit pages that crawlers cannot reach: staging environments, password-protected pages and local builds.
