I've just found a pretty cool resource I wanted to share with you: the easiest way to add emojis to your Facebook posts.
Here's the URL: https://www.piliapp.com/facebook-symbols/
It shows you a list of colourful emojis you can copy-paste in a snap. Simply click on the emoji you want to copy and it will be added to a "copy box" at the top of the page. Then if you click copy, the whole sequence is copied to your clipboard and you can paste it into your Facebook post. Voilà!
Inserting emojis into your Facebook posts will usually boost the engagement of your readers by enhancing the X-factor of your copy.
