Paste a page's HTML to instantly audit its meta tags — title, description, canonical, robots, Open Graph and Twitter Cards — with length checks and clear pass/warn/fail grades. 100% in your browser — nothing is uploaded or stored.
Paste HTML source, not a URL — the analyzer cannot fetch external pages (that keeps it private and instant). Build tags with the Meta Tag Generator first if you need to.
🔒 Everything runs in your browser. Your HTML is never uploaded, logged or stored.
The Meta Tag Analyzer reads a page's HTML and audits every important SEO tag for you — the title, meta description, canonical, robots directives, charset, viewport, Open Graph and Twitter Card tags. It checks each one for presence and correct length, then gives a clear pass, warning or fail grade and an overall score, so you can spot exactly what to fix.
It is part of the SERP & Content Analysis group in our free SEO Toolkit, and it is the natural partner to the Meta Tag Generator — build your tags there, then verify them here. Refine titles with the SERP Snippet Preview and check focus with the Keyword Density Analyzer, and review heading structure with the Heading Structure Checker. Everything runs in your browser — your HTML is never uploaded or stored.

A graded checklist of every important meta tag.
The analyzer parses the HTML you paste and inspects the meta tags that matter most for search and social. It confirms each tag is present, checks lengths against recommended ranges, and warns about issues like a missing viewport or a noindex robots directive. The result is a prioritised report card plus an overall score, so you know exactly where to focus. It is part of the SERP & Content Analysis group.
| Tag | What's Checked | Ideal |
|---|---|---|
| Title | Present and length | 30–60 characters |
| Meta description | Present and length | 120–160 characters |
| Canonical | Present | Self-referencing URL |
| Meta robots | Index vs noindex | Indexable |
| Charset | Present and value | UTF-8 |
| Viewport | Present and responsive | device-width |
| Open Graph | title, description, image | All three |
| Twitter Card | Present | twitter:card set |

Fetching another website from the browser is blocked by cross-origin security, and a server-side fetch would mean sending your URL to us. Pasting the HTML keeps everything local and private, and lets you analyze staging pages, password-protected pages and drafts that a URL fetcher could not reach.
Each tag carries a weight based on its SEO importance — the title and description weigh most. A passing tag earns full marks, a warning earns half, and a missing or failing tag earns none. The weighted total is scaled to a 0–100 score, so it reflects both completeness and quality.
They are sensible guidelines, not hard rules. Google measures titles and descriptions in pixels, not characters, so actual truncation depends on the characters used. The character ranges here are a reliable proxy; for precise width, use the SERP Snippet Preview tool.
No. The HTML is parsed locally in your browser with the built-in DOM parser. Nothing you paste is uploaded, logged or stored, so the tool is safe for confidential and unpublished pages.

Everything about analyzing your meta tags.
It parses the HTML you paste and audits the key SEO meta tags — title, description, canonical, robots, charset, viewport, Open Graph and Twitter Card. It checks presence and length, grades each tag pass, warning or fail, and gives an overall 0–100 score so you know what to fix.
Yes, completely. There is no cost, no sign-up and no limit on how many pages you check. The tool runs entirely in your browser, so there are no server costs and nothing to pay for.
Browsers block fetching other websites for security, and a server fetch would mean sending us your URL. Pasting the HTML keeps everything local and private, and lets you analyze staging pages, drafts and password-protected pages a URL fetcher could not reach.

Aim for roughly 30–60 characters for titles and 120–160 for meta descriptions. These are guidelines, not hard limits — Google truncates by pixel width, not character count, so use the SERP Snippet Preview for exact width.
Yes. It looks for the core Open Graph tags — og:title, og:description and og:image — and flags any that are missing, plus the twitter:card tag. These control how your links look when shared on social platforms.
Yes. If the meta robots tag contains noindex, the analyzer flags it with a warning, since that keeps the page out of search results. This helps you catch pages accidentally blocked from being indexed.
