Primary Open Graph tags
Google Chat uses standard OG tags only – no platform-specific tags:
| Tag | Used for |
|---|---|
og:title |
Preview title (bold text) |
og:description |
Description below the title |
og:image |
Preview image |
og:url |
Canonical URL |
og:site_name |
Site name above the title |
Fallback behavior
When OG tags are missing:
| Missing tag | Falls back to |
|---|---|
og:title |
<title> element |
og:description |
<meta name="description"> |
og:image |
No image shown |
og:site_name |
Domain name |
Custom Chat app link previews
Google Workspace developers can build Chat apps that provide custom link preview integrations via the Google Chat API – rich, interactive cards with buttons and structured data. This is a separate system from OG tag-based previews and requires the Google Workspace Developer Console.
Recommended minimal setup
<meta property="og:title" content="Your Page Title">
<meta property="og:description" content="A brief description of the page">
<meta property="og:image" content="https://example.com/image.jpg">
Google Chat renders a compact card with the title, description, and image alongside the message.
