'Cross Channel' report shows you a general overview of activity proportions and posting density in different social networks
By comparing the level of engagement with your posting density, you can understand which social channels are the most effective and which are the least effective
For example, based on this chart we can see that most of the activity comes from Facebook (high Conversation, Amplification, and Applause rates),
but if we take a look at Posts, we'll see that only a tiny fraction of posts comes from Facebook, and most of them comes from Twitter
So we post a lot in Twitter but gain most of the response from Facebook, where we post much less
Then maybe we need to change our posting policy to focus more on Facebook, as it seems to be a much more effective channel for us than Twitter
