Website Meta Tag Checker
See exactly what meta tags, OG data and SERP snippet any page sends.
This check runs through this site's own server, so it works for any public URL — no CORS or browser restrictions.
How to use the Website Meta Tag Checker
- 1 Enter any public page URL and click Check meta tags.
- 2 Review the title, description, canonical, robots and other core tags with length hints.
- 3 Check the Open Graph and Twitter Card tables and the SERP and social share card previews.
Examples
- ▸ A title over roughly 60 characters or 600px is flagged "likely truncated" in the SERP preview, just as Google would cut it off.
Frequently asked questions
What does this tool actually check?
It fetches the page and parses the server-rendered HTML: the <title>, meta description, canonical link, robots and viewport tags, charset, favicon, the first three <h1>s, and all Open Graph / Twitter Card meta tags.
Does it work on any website, or only ones I own?
Any public URL — the check runs through this site's own server, not your browser, so there are no CORS or same-origin restrictions like a client-side fetch would hit.
Why don't you load my og:image directly in the preview?
The image URL is shown as text instead of being embedded, since it may point to a slow, private or unreachable host. You can open it yourself to confirm it loads.
Does this see JavaScript-rendered meta tags?
No — it reads the initial HTML response, the same way most crawlers and link-preview bots do. Tags injected client-side after hydration will not show up here even though a browser (or Googlebot, which does render JS) might see them.
