Open Graph and Twitter Card Metadata: How Link Previews Work

When you share a URL on social media, messaging apps, or Slack, these platforms fetch the URL's HTML and extract structured metadata from `<meta>` tags in the `<head>` to generate a visual preview card. Open Graph Protocol (introduced by Facebook) uses `og:title`, `og:description`, `og:image`, and `og:type` tags. Twitter Cards use `twitter:card`, `twitter:title`, `twitter:description`, and `twitter:image` tags — with fallback to OG tags if Twitter-specific tags are absent.

Each platform has different display rules: Facebook truncates titles at ~55 characters and descriptions at ~65 characters. Twitter's large summary card requires a 2:1 aspect ratio image (1200×628px recommended). LinkedIn displays OG tags with slightly different truncation rules. Slack uses a simpler text+image layout. Getting preview metadata right matters for click-through rates — research consistently shows that compelling preview cards significantly outperform links that render as plain text.

Our tool fetches the target URL's HTML and parses all relevant meta tags, rendering platform-accurate mockups of how the page will appear on each platform — saving you from needing to share the URL on each platform individually to see how it looks.

Common Use Cases
1

Verify blog post social previews

Check how a newly published article will appear when shared on Twitter, Facebook, and LinkedIn before promoting it.

2

Debug missing or incorrect OG tags

Identify when og:image is missing, og:title is truncated incorrectly, or Twitter Card type is misconfigured.

3

Test landing page social media appearance

Ensure new product pages and campaign landing pages display compelling preview cards before launch.
