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. Click "Scrape Again" to fetch fresh data.

Twitter/X

Caches until you request a re-scrape via the Card Validator. Note: The validator UI was removed but the API still works.

Has a particularly sticky cache. Clear via Post Inspector. May take up to 7 days for cache to fully refresh.

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.
