bg-szy SEO On-Page: Open Graph
Guides implementation of Open Graph meta tags for social media previews (Facebook, LinkedIn, Slack, Discord, etc.). Pages with proper OG tags get 2–3× more clicks than bare URL links.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Scope (Social Sharing)
- Open Graph: Facebook-originated protocol; controls preview card when links are shared on social platforms
The 4 Essential Tags
Every shareable page requires these minimum tags:
<meta property="og:title" content="Your Page Title">
<meta property="og:description" content="Your description">
<meta property="og:image" content="https://yourdomain.com/image.png">
<meta property="og:url" content="https://yourdomain.com/page">
| Tag | Guideline |
|---|---|
| og:title | Keep under 60 chars; compelling; match page content |
| og:description | 150–200 chars; conversion-focused |
| og:image | Absolute URL (https://); 1200×630px recommended |
| og:url | Canonical URL; deduplicates shares |
Recommended Additional Tags
| Tag | Purpose |
|---|---|
| og:type | Content type: website, article, video, product |
| og:site_name | Website name; displayed separately from title |
| og:image:width / og:image:height | Image dimensions (1200×630px) |
| og:image:alt | Alt text for accessibility |
| og:locale | Language/territory (e.g., en_US); for multilingual sites |
Image Best Practices
| Item | Guideline |
|---|---|
| Size | 1200×630px (1.91:1 ratio) for Facebook, LinkedIn, WhatsApp |
| Format | JPG, PNG, WebP; under 5MB |
| URL | Absolute URL with https://; no relative paths |
| Unique | One unique image per page when possible |
Common Mistakes
- Using relative image URLs instead of absolute https://
- Images too small or wrong aspect ratio
- Empty or placeholder values
- Missing og:url (canonical)
