When you share a RallyUp link on Facebook, you'll be able to see the title of your campaign and a corresponding image.
Facebook controls how often shared information is refreshed. This means that outdated information may appear if you share your link after making changes to your campaign’s image or title.
If you're seeing an outdated image or title, here's how to fix it:
Go to this URL: https://developers.facebook.com/tools/debug/sharing/
Copy the URL you want to share on Facebook.
Paste your link in the bar at the top and click debug.
Click “scrape again.”
You should now see the updated image and title when you share your campaign link again on Facebook.
