About the Meta Tags Extractor
The Meta Tags Extractor fetches any public URL server-side and pulls out every meta signal — standard meta tags, Open Graph, Twitter Cards, canonical, hreflang, JSON-LD structured data, microdata, favicons, and web manifest links. Every tag is copyable individually, and the whole extraction can be exported as JSON.
It also renders live preview cards matching how Facebook, Twitter (X), LinkedIn, and Google will show the link when shared or ranked — so you can catch a broken image or truncated description before you publish.
Tag groups extracted
🏷️ Basic meta
description, keywords, robots, viewport, author, generator, theme-color, color-scheme, referrer.
📱 Open Graph
All og:*, article:*, book:*, video:*, music:*, profile:* tags. Open Graph is the shared standard for how a link previews on Facebook, LinkedIn, Slack, WhatsApp, iMessage, and dozens of other platforms.
🐦 Twitter Cards
All twitter:* tags (both name="twitter:*" and property="twitter:*" variants).
📘 Facebook / app IDs
fb:app_id, fb:admins, and related tags used by Facebook Insights and the Sharing Debugger.
🔖 Other meta
Everything else — http-equiv, itemprop, publisher-specific tags, custom namespaces.
🔗 Link tags
canonical, alternate (with hreflang), prev/next, RSS/Atom feeds, preload, prefetch, preconnect, DNS-prefetch, manifest, and all icon variants.
🖼️ Favicons & touch icons
Every <link rel="icon">, apple-touch-icon, and mask-icon, with resolved absolute URLs and previews.
📊 JSON-LD structured data
Every <script type="application/ld+json"> block, pretty-printed, with detected @type values highlighted. JSON-LD is what powers Google rich results — FAQ expandables, recipe cards, breadcrumbs, star ratings, video thumbnails.
📐 Microdata
Every itemscope element, grouped by itemtype. Microdata is an older format Google still reads.
Live preview cards
The tool renders four mockups: Facebook (large image + title + description), Twitter (summary card or large image), LinkedIn (matching Facebook's OG spec), and Google search result (URL + title + meta description). Fields fall back sensibly — Twitter uses twitter:* if set, otherwise og:*, otherwise page title.
These match documented platform rendering rules for the visible fields; actual live rendering may differ due to platform caching or image cropping. For definitive validation, use Facebook Sharing Debugger and Twitter Card Validator for a live share test.
Common uses
- Pre-publish audit — check every meta tag before hitting publish, catch missing OG images or truncated descriptions.
- Migration verification — after a redirect or CMS switch, confirm the new URLs carry the intended meta tags.
- Competitor research — see how competitor pages structure their meta, schema, and social previews.
- Debug rich results — extract JSON-LD blocks from a live page, paste into Google's Rich Results Test.
- Copy meta tags into a template — grab canonical or hreflang blocks from a reference site as a starting point.
Privacy & limits
Fetching runs server-side (must, for CORS), SSRF-guarded (private IPs blocked), 12 s timeout, 2.5 MB response cap, rate-limited to 20 requests per minute per IP. Nothing is stored — the report is returned to your browser and forgotten.
