You have the option to pin up to a maximum of 3 posts to your profile, providing a quick reference for visitors to your page. The last post you pin will be displayed at the top of the list. Follow these steps to pin posts to your profile:
Click the ellipsis "..." to the right of your post.
Select 'Pin to your profile.'
If you've already pinned the maximum number (3) of posts and you attempt to pin another post, you'll receive the following pop-up message: "You can only pin up to three posts; pinning a new post will replace the oldest pin."
