Social media is meant to be just that, social. Like when we are having a chat with our mates and can't wait to share news of a bargain, the great workmanship of a tradesman, or a joke! You judge the popularity of the discussion by the response. If everyone laughs at your joke, you know it was funny, yes?
Same goes with content.
The most prized response on Facebook is the share, second is a comment, and third is a like. You can get even more mileage when someone likes the post that has been shared. This shows up in your Insights as a like on the share as opposed to a like on the post. It's a pretty high prize or achievement
Be an Activist
So whether you are using Facebook for business or personal, be active. If you see something you like or appeals to you, respond. Don't stay silent. Make our efforts worthwhile.
Aim for good engagement
Good engagement means you have hit the target! Good work!
