## Why Isn't My OG Image Updating?

Social platforms cache link previews aggressively to reduce server load. After updating your OG tags, you'll need to manually clear each platform's cache.

Cache invalidation is unreliable

Platform cache clearing is flakey and may not work consistently. You may need to try multiple times or wait for the cache to expire naturally.

### Facebook

Caches for approximately **30 days**. Force refresh via the [Facebook Sharing Debugger](https://developers.facebook.com/tools/debug/). Click "Scrape Again" to fetch fresh data.

### Twitter/X

Caches until you request a re-scrape via the [Card Validator](https://cards-dev.twitter.com/validator). Note: The validator UI was removed but the API still works.

### LinkedIn

Has a particularly sticky cache. Clear via [Post Inspector](https://www.linkedin.com/post-inspector/). May take up to 7 days for cache to fully refresh.

### WhatsApp

Preview style varies by client version and context - some show **square (1:1)** crops, others show full **1.91:1** cards. No official cache clearing tool - cache typically refreshes within 24-48 hours. For best compatibility, use `1200x600px` with important content centered.

### Pro Tips for OG Images

- Use **1200x600px** for optimal display across platforms
- Keep important content in the center 800x400px safe zone
- Use absolute URLs for og:image (relative URLs won't work)
- Add cache-busting query params when updating: `?v=2`

## Frequently Asked Questions

<details>

<summary>01 ### What is a social share debugger?

</summary>

A social share debugger lets you preview how your links will appear when shared on platforms like Twitter, Facebook, LinkedIn, and Slack. It checks your Open Graph (OG) tags and Twitter Card meta tags to ensure your content displays correctly with the right image, title, and description.

</details>

<details>

<summary>02 ### Why isn't my image showing when I share on Twitter?

</summary>

Twitter caches your page's meta tags. If you updated your og:image after sharing, Twitter still shows the old image. Use this debugger to clear Twitter's cache by clicking "Clear Cache" next to the Twitter preview. Also ensure your image meets Twitter's requirements: minimum 120x120px, maximum 5MB, and accessible via HTTPS.

</details>

<details>

<summary>03 ### How do I clear Facebook's OG cache?

</summary>

Facebook caches Open Graph data for about 7 days. To force a refresh, use Facebook's Sharing Debugger or this tool's "Clear Cache" button. Note that Facebook requires og:image to be at least 200x200px (1200x600px recommended) and accessible without authentication.

</details>

<details>

<summary>04 ### What Open Graph tags do I need?

</summary>

The essential OG tags are og:title, og:description, og:image, and og:url. For better results, also include og:type (usually "website" or "article"), og:image:width, og:image:height, and og:site_name. Twitter also uses twitter:card, twitter:title, and twitter:image for Twitter Cards.

</details>

<details>

<summary>05 ### Why do LinkedIn and Slack show different previews?

</summary>

Each platform has its own cache and rendering rules. LinkedIn and Slack both cache link previews for about 7 days. This debugger shows you exactly what each platform will display. To refresh Slack, use the [Slack URL Debugger](https://api.slack.com/tools/debug/url).
