Logo that displays next to web URL
Hello,
This may be a very simple question. When I post my URL on Facebook, it comes up with 9 thumbnails I can select to display next to my URL. However, none of these thumbnails are my logo. They're all the logos to companies I have posted on my website. How do I add an optional thumbnail that populates when I paste my URL?
While I'm at it, how do I set a Favicon??
Thanks!
