If you’ve ever posted a link from the same site on Facebook, you’ll sometimes notice that the preview image doesn’t match the data you know is on that site. To fix this, you’ll need to refresh your posts URL.
Why? you ask. Well, Facebook caches information that they took from their first scan of the page, and continues to draw on this information, until told to update!
Why doesn’t deleting and re-posting the link work? Facebook’s cache is holding that original scan the link, and will continue to give you and everyone else the same outdated preview.
How do you fix this???
There are three methods you can try to update Facebook’s cache, I have written one out here, with a link to the original article by John Doppler that showed me how to update it, as well as two more methods, which are a bit harder.
Step 1: Click the date and time stamp under your name at the top of the post.
Step 2: CLICK THE THREE DOTS In the upper right hand side of the post across From your name, and choose the “Refresh share attachment” option.
Step 3: Click Save
Step 4: Reload page and check!
