Quick Tool Overview

The Meta Tag Analyzer takes a page's HTML and audits every tag that describes it: title, description, canonical, robots, viewport, charset, language, the Open Graph set, the Twitter card set and the icons. Each is measured and marked, missing tags are listed with the markup to add, and nothing is fetched — so staging and password-protected pages work.

About the Meta Tag Analyzer

Paste the HTML of a page — the head alone is enough — and every tag that describes it is pulled out and checked: title, description, canonical, robots, viewport, charset, language, the Open Graph set, the Twitter card set and the icons. Each is measured, and what is missing is listed alongside what is there.

The checks are the ones that actually change something. A title measured in pixels rather than characters. A canonical that is relative, or that points at a different host. A robots tag that says noindex on a page you meant to rank. Two title tags, which happens more often than anyone admits and leaves Google to pick. A missing viewport, which affects how mobile results render. Because nothing is fetched, this works on a staging build, a page behind a login, or a template you are still writing.

Key features of the Meta Tag Analyzer

Every tag that matters

Title, description, canonical, robots, viewport, charset, language, Open Graph, Twitter and icons.

Duplicate tag detection

Two title tags or two canonicals leaves Google to choose. Both are found and reported.

Measured, not just listed

Lengths are given in pixels and characters against the real SERP limits.

Missing tags with the fix

Anything absent is listed with the markup to paste, rather than as a bare complaint.

Works on unpublished pages

No fetch means staging, local builds and pages behind a login all analyse fine.

How to use the Meta Tag Analyzer

  1. 1

    Copy your page source

    View source on the page and copy it, or copy just the head element — either is enough.

  2. 2

    Paste it in

    The tags are parsed out in your browser. Nothing is sent anywhere, so staging pages are fine.

  3. 3

    Read the report

    Each tag is shown with its value, its measured length and a pass, warning or fail.

  4. 4

    Fix what is flagged

    Missing tags are listed with the markup to add, so you can copy the fix straight out.

Frequently asked questions

Because a browser cannot fetch another site's page without that site allowing it, and building a server that could would mean sending your URLs to us. Pasting the source keeps everything on your machine and works on pages a fetcher could not reach anyway.
