About the Meta Tag Analyzer

Meta Tag Analyzer extracts every SEO-critical meta tag from a page's HTML and grades it against modern best practice. Paste the source of any page (right-click → View page source) and the tool parses the <head> with the browser's built-in DOMParser, pulls the title, description, canonical, robots directive, viewport, language, Open Graph (og:title, og:description, og:image, og:url), Twitter Card, structured-data JSON-LD blocks and the page's primary H1. It then reports each tag as a ticked or flagged checklist, with length warnings — Google currently shows up to 60 characters of the title and ~155 characters of the description on desktop search results.

How to use

Right-click your page in the browser and choose View page source.
Copy the HTML and paste it into the analyzer text area.
Click Analyze to see a ticked / flagged report of every SEO tag.

Benefits & key features

Cross-check on-page SEO in seconds — no install, no signup.
Title and description length warnings catch CTR-killing issues.
Verifies presence of canonical, robots, OG and Twitter tags.
Zero upload — the HTML stays in your browser.

Pro tip

For sites that render via JavaScript, paste the rendered HTML (devtools → Elements → copy outerHTML on <html>) rather than the static source.

Why choose toolsfy for Web & SEO tools?

On-page SEO is still 80% of the ranking battle and can be audited in 30 seconds — yet the typical SEO SaaS wants $49/month to tell you your meta description is 204 characters long. toolsfy's SEO utilities compute the same signals in your browser, against the HTML you paste, with zero account friction and zero data leaving your device.

Common use cases

Freelance SEOs running a quick pre-launch audit on a client's landing page before it hits production search results.
Publishers generating a validator-friendly sitemap.xml for a new subdomain in under a minute, without firing up an XML editor.
Developers producing a spec-correct robots.txt for a staging environment so crawlers stop indexing QA URLs by accident.

Frequently asked questions

Do these tools crawl my website?

No. Paste the HTML you want to analyse — the tool parses it locally and returns a report. Nothing is fetched by toolsfy.

Is the advice up to date with Google's current guidelines?

Length budgets (60-char titles, 155-char descriptions), canonical rules and sitemap schema reflect the latest Google Search Central documentation.

Can I export the SEO report?

Every analyser has a Copy-to-clipboard button that produces a plain-text summary ready to paste into a client email or a ticket.
