Practical guide to open graph cache refresh: formulas, workflow, implementation pitfalls, and a direct execution playbook with OG Preview Tool.
Go to tool
Visual Open Graph tag editor for social networks.
You updated your page's OG image. You paste the URL into Slack and... the old image appears. Facebook shows the old title. LinkedIn ignores your changes entirely. This is OG caching, and every platform does it.
When a platform first fetches your URL, it scrapes the meta tags and caches the result. Facebook caches OG data for approximately 24 hours. LinkedIn caches for about 7 days. Twitter caches until you explicitly purge it. Telegram caches until the chat message is re-sent.
During this cache window, no matter how many times you update your meta tags, the old preview persists.
Facebook Sharing Debugger:

Twitter/X Card Validator:

Paste your URL and submit. Twitter fetches fresh data and shows you the preview.
LinkedIn Post Inspector:
https://www.linkedin.com/post-inspector/
Paste your URL, click Inspect. LinkedIn purges its cache and fetches new data.
If the tools above don't work, append a query parameter to your og:image URL:
<!-- Before -->
<meta property="og:image" content="https://site.com/og.jpg" />
<!-- After -->
<meta property="og:image" content="https://site.com/og.jpg?v=2" />Platforms treat og.jpg?v=2 as a new URL and fetch it fresh. Increment the number each time you update.
og:image points to HTTP. Many platforms silently refuse HTTP images.og:image URL redirects (301/302), some crawlers give up after 1-2 redirects. Use a direct URL.Test your current OG setup in OG Preview before sharing. For size specs, see OG Image Sizes 2026.
