A meta tag preview tool inspects a webpage's HTML code to extract and validate social metadata (including og:title, og:description, og:image, og:type, og:site_name, and twitter:card). It generates pixel-accurate visual simulations of how your link appears when shared across Google Search (Desktop & Mobile), Facebook, Twitter/X, LinkedIn, Discord, Slack, Pinterest, and WhatsApp/Telegram.

The universal recommended size for an Open Graph banner image is 1200 × 630 pixels, maintaining a 1.91:1 aspect ratio. For Twitter/X Large Image cards, 1200 × 628 pixels (~2:1) is standard. For compact square summary cards, use a 1:1 square image (at least 300 × 300 pixels). Ensure image files remain under 5 MB in PNG, JPG, or WebP formats.

Google desktop search results allocate approximately 580 to 600 pixels of visual width for webpage titles (roughly 50 to 60 characters depending on letter widths). Meta descriptions are truncated after ~155 to 160 characters on desktop (and ~120 characters on mobile). Our tool provides real-time proportional pixel estimation and character meters to ensure headlines stay fully visible.

The SEO Health Scorecard audits 8 critical technical dimensions: Title presence and length (30–60 chars), Description presence and length (70–160 chars), Open Graph image availability with absolute HTTPS protocol, Twitter Card type configuration, canonical link validation, robots indexing directives, and author attribution, calculating an algorithmic 0–100 quality score.

The Open Graph protocol was established by Facebook and adopted broadly by LinkedIn, Slack, Discord, and Pinterest. Twitter/X uses its proprietary twitter:card, twitter:title, and twitter:image specifications. While Twitter falls back to og: tags if twitter: tags are missing, declaring both gives you fine-grained control over whether Twitter renders a full-bleed 1.91:1 hero banner or a compact thumbnail.

Social networks aggressively cache scraped metadata for days. When you update your website's meta tags, use the Official Platform Debuggers in our toolbar: Facebook Sharing Debugger, LinkedIn Post Inspector, and Pinterest Pin Validator to force their crawlers to re-scrape and purge stale cached preview images instantly.

Our Code Studio exports production-ready snippets across 8 architectures: standard HTML5 <head>, Next.js 14+ App Router metadata exports, Nuxt 3 useSeoMeta() composables, Remix / React Router v7 meta() arrays, React Helmet, SvelteKit <svelte:head>, WordPress PHP hooks, and Schema.org WebPage JSON-LD.

AI search engines like ChatGPT Search, Perplexity, and Claude ingest standard HTML title, meta description, and canonical tags to contextualize and cite web content in generated answers. Ensuring clean, descriptive metadata directly improves how autonomous AI agents summarize and reference your pages.

Yes! Use the 'Direct Builder & HTML Paste' studio tab to paste raw HTML <head> markup or type custom metadata directly. You can also upload a local image file from your computer or drag-and-drop it into the image dropzone to preview your social cards before pushing code to production.
