Social networks
It depends on each social network. There are metrics that give you a broad idea of how your brand's interactions are going, as well as formulas that, when applied, will give you results that will serve you exponentially.
Facebook. You can tell if your interactions are going well on this social network by the number of likes on the fan page, posts, shares, reach and reactions.
There are two formulas that can give you an idea of your engagement rate. One of them is the linear formula which is:
Engagement rate = likes + comments + shares / reach of the post or page
There is also the weighted formula, which goes like this and depends on your strategy; that is, if you value likes or shares more:
Engagement rate = likes + 2* shares + 3* comments / reach of the post or page
Twitter. You can find out your level of interaction on this platform by checking the number of retweets, mentions, likes, reach, followers and unfollows.
Just like on Facebook, there is a linear formula to measure engagement:
Engagement rate = favorites + retweets + mentions / reach of the tweet or profile
And a weighted formula:
Engagement rate = favorites + 2* retweets + 3* mentions / reach of the tweet or profile
On the other hand, it is important that you take into account how many follows and how many unfollows you have during periods of time that you can determine and thus see if the content you are producing truly attracts the attention of Twitter users.
