You’ve finished a great blog entry. You share it to Facebook – and then realize there’s a typo in the headline, or you forgot to add an image. You cancel the Facebook share, fix the blog, update it, and share it to Facebook again. The headline still has a typo, or the image is still missing. The page has updated, the link goes to the updated page, but the preview on Facebook did not update. What happened?
Facebook does not automatically refresh link summaries and images, so if something changes on a page that has been shared to Facebook, the link preview might not update to show the change. It does not matter whether you shared it or someone else did. For example, you might share a link to a newspaper story, and see a description and image on your Facebook feed that is from an earlier version of the story.
Fortunately, there is an easy way to force Facebook to refresh the link summary and image.
- Make sure you are logged into Facebook.
- In a new tab, go to this page: https://developers.facebook.com/tools/debug/og/object/
- Enter the URL for the item you want to share.
- Click the button that says “Fetch New Scrape Information.”
- Facebook refreshes and displays all the data it has about the shared item, including an updated summary and image. You can close this tab.
Now you can share the post, and this time the link preview will be current.
