Please note: We’ve changed the location of the ‘SEO‘ section. The principle in this video still applies, as you can still change the thumbnail for Facebook by clicking on the ‘Page Settings‘ button (next to the page name), and then click on ‘SEO Settings‘ tab in the window that pops up.
Solving the issue of the image not updating on Facebook…
If your image doesn’t update when you post the URL on Facebook, it might be because Facebook has cached the image it had previously. To force an update, visit https://developers.facebook.com/tools/debug/ and paste in your Squeeze Page URL.
That will force the image to update.
Then reload your Facebook page and try to share the URL again. It should have your new image.
