Meta tags checker

You ship a page, share the link, and the card comes up blank — wrong title, no image, the old description from three rewrites ago. Paste the URL here and see exactly what Google and the social scrapers read: title, meta description, canonical, Open Graph, Twitter Card — with a live preview of how the link will actually show up.

Free and anonymous. Fair-use limit: 10 checks per hour per IP.

What meta tags are, and which ones earn their place

Meta tags live in the <head> of a page. Visitors never see them, but search engines and social platforms read them to decide how your page appears in results and in shared links. Get them wrong and the page still works — it just shows up looking careless, or not the way you intended.

Most of the head is noise. These are the tags that change what people actually see:

  • Title tag: the clickable headline in Google results and the browser tab. The single most important tag on the page.
  • Meta description: the snippet under the title in search. Google may rewrite it, but a good one still wins more clicks than a blank.
  • Canonical: tells Google which URL is the real one when several show the same content. Wrong canonicals quietly bury pages.
  • Robots: a noindex here keeps the page out of Google entirely. Worth checking before you wonder why a page never ranks.
  • Open Graph & Twitter Card: the title, description and image used when the link is shared on Facebook, LinkedIn, Slack or X. No og:image means no thumbnail.

What this tool can't tell you: whether the copy is any good, whether the page is fast, or whether Google has indexed it. For a fuller on-page review try the on-page SEO checker; for structured data, the schema markup validator.

How to use it

  1. Paste the page URL — a page you just shipped, or one whose share preview looks off.
  2. Read the two previews: the Google result and the social card show you what searchers and social platforms will actually display.
  3. Scan the checks: title and description length, missing canonical or viewport, a stray noindex, gaps in your Open Graph tags.
  4. Expand the full tag list to copy any value, or grab the whole set as CSV.

Frequently asked questions

What meta tags does this read?

The title tag, the html lang attribute, the canonical link, charset, and the standard meta tags: description, keywords, robots, viewport, author, theme-color and generator. It also reads the full Open Graph block (og:title, og:description, og:image, og:url, og:type, og:site_name and the rest) and the Twitter Card block (twitter:card, twitter:title, twitter:description, twitter:image). Anything else in the head is grouped under Other.

Why does the social preview look different from the Google preview?

They read different tags. The Google preview uses the title tag and meta description. The social card uses Open Graph first, then Twitter tags, then falls back to the plain title and description — which is exactly how Facebook, LinkedIn, Slack and X resolve them. If a page has no og:image, the social preview shows no image, because that's what people would actually see when they share the link.

Are the length warnings official Google limits?

No. Google doesn't publish a character limit for titles or descriptions — it truncates by pixel width, which varies by device. The 30–60 characters for titles and 70–160 for descriptions are widely used rules of thumb that keep most snippets from being cut off. Treat a warning as a prompt to look, not a hard failure.

Does it render JavaScript?

No. It reads the raw HTML the server returns, which is what most crawlers and social scrapers see first. If a page injects its meta tags with JavaScript after load, this tool won't see them — and neither will many social scrapers, so a missing tag here is worth knowing about.

Is this an SEO audit?

No. This tool extracts meta tags and flags a few common mistakes. For a broader on-page review — headings, image alt text, internal links, indexability — use the on-page SEO checker. For structured data specifically, use the schema markup validator.
