User-Generated Content

User-Generated Content (UGC)

Content created by users rather than brands, including reviews, photos, and videos shared on social platforms.

技術的詳細

User-Generated Content affects how content appears when shared across social media platforms. Social platforms use link preview crawlers that fetch and parse meta tags from shared URLs. These crawlers cache aggressively — changes may take hours to propagate. Each platform has its own debugger tool (Facebook Sharing Debugger, Twitter Card Validator, LinkedIn Post Inspector) for previewing and clearing cached link previews. Properly configured social metadata can increase click-through rates by 30-50% compared to links without preview images.

```html
<!-- User-Generated Content: social markup example -->
<meta property="og:title" content="Page Title">
<meta property="og:description" content="Description for social sharing.">
<meta property="og:image" content="https://example.com/image.png">
```
