Why are images for my posts on Google My Business missing?
As opposed to other social platforms, GMB does not show images for your shared links, unless you explicitly add your images for the post.
When scheduling your posts for GMB, you will need to add an image to your post and otherwise, your content will be posted without any image. This is a restriction of GMB and link previews are not shown unless you add an image to your posts.
