Using Bufferapp and analyzing Google+ posts:
- Even if there is no huge visible interaction on a post, the click through rates are astonishing.
The app collects all the clicks, also from reshares because of the bit.ly link shortener I use.
I sometimes repost the good content posts and being able to do it from the app's Analytics part, the link stays the same and collects further data. Even posting / scheduling the exact same post on Facebook is possible.
