Meta Tag Checker
Inspect any URL's title, meta description, H1, Open Graph, Twitter Card, canonical, hreflang, robots meta and schema.org types. The signals search engines and social platforms actually read.
What this tool checks
- Title tag — what shows as the blue link in search results
- Meta description — the snippet under the link
- H1 heading — primary on-page topic signal (and how many H1s exist)
- Canonical URL — your declared master version of the page
- Open Graph — Facebook, LinkedIn, WhatsApp link previews
- Twitter Card — X/Twitter link previews
- Schema.org JSON-LD types — structured data declarations
- Hreflang — international/multilingual alternates
- Robots meta — index/noindex/follow/nofollow directives
Common questions
Is this really free?+
Yes. No card, no email collected, just hit submit. Rate-limited per IP to keep it usable for everyone.
What if my URL needs login?+
We can only see what a search-engine crawler sees — public, unauthenticated content. Pages behind auth won't return useful results.
Can I check competitors' pages?+
Yes. Anything publicly accessible. That's part of the point — see what they're doing differently.
What's the difference between this and the full Flatline audit?+
This tool reads tags. The full audit grades them, plus runs PageSpeed, scoring everything into a 0-100 Visibility Score with a prioritised fix list.
