One year in social media terms can be an eternity. Loads of changes have happened since then, new updates that can make your measurements old. Thanks to you all, and specially to Juan Luis Azkarate and Lugha, who opened an interesting conversation around this matter on the previous post, we’ve tried to find the best and latest formula.

On the old post we talked about the following ways to calculate the rate of fans’ and followers’ engagement on Facebook and Twitter:

Formula to calculate the engagement rate on Facebook - Social With It

Formula to calculate the engagement rate on Twitter - Social With It

However, since then Facebook have added some new metrics that actually make the calculation easier, such as PTAT (People Talking About This). This value that you’ll easily find among your Stats on your Facebook fan page is the result of Likes+comments+posts in a given day.

The updated version of this formula, according to Socialbakers adds the number of posts published in the page during a given day:

Formula engagement Facebook - Social With It -

“Likes+comments+shares” can be replaced for the PTAT metric of that given day. But what happens then if what you want to calculate is a longer period of time? Well, our reader Juan Luis Azkarate proposed this formula:

Formula engagement Facebook in a month - Social With It

Bear in mind that the result is not totally accurate but an approximation. For a deeper and most detailed metric, you could use the Facebook statistics and download it into an Excel document or buy a tool that can give you this data.

What don’t you check this formula and let us know how well it works? We’ve already checked it and we love it! But if you know a better one, please share it with us on comments!
