Heyo Hawk!
In my case, I use the engagement rate to find out what kinds of activity did well. This also helps me to figure out what content works/does not work.
For example, since there’s an activity every day, maybe on day 2 or day 3 there was higher activity due to a trending topic. That means engagement was higher for these 2 days with X%.
In this case, I’d have to look at raw stats like page views, posts (dashboard) or topic stats (Likes, comments, views). It would be better if I had something like a consolidated metric to represent this data better.
