Single-page meta tag audit
Every meta tag on the page, graded and ready to fix.
Paste a URL. MetaTagAuditor fetches the page server-side, reads its <head>, and returns a prioritised list of what's missing, what's truncated and what to paste in its place.
Try it on a public page
- example.comThe IANA reference page — a deliberately bare document.
- developer.mozilla.orgMDN's own meta element reference, a thoroughly tagged page.
- nextjs.orgA modern framework homepage with full Open Graph tags.
These run live against the real page when you open them, so the result reflects whatever those sites ship today.
18 checks, in <head> order
- html lang
- charset
- viewport
- title
- description
- robots
- canonical
- og:title
- og:description
- og:image
- og:url
- og:type
- twitter:card
- twitter:title
- twitter:image
- favicon
- h1
- img alt
What you get back
- The current value
- Exactly what the page returned for each tag, in monospace, including the character count where length matters.
- Why it matters
- One plain sentence per issue — the kind you can paste straight into a client email without rewriting.
- The replacement tag
- Copy-ready markup for every failing check, pre-filled with the page's own URL and copy where possible.
MetaTagAuditor reads the HTML a plain HTTP request returns. It does not run JavaScript, so tags injected on the client after load will not show up. How it works in detail.
