We use
Engagement to rank your Google+ posts.
Latest Posts widget sorts posts by time of creation. Most recent posts are at the top.
Post Engagement is calculated using the sum of weighted user actions. We applied different weightings to actions. Because comments, for example, are more "valuable" than Plus Ones (Likes).
Post Engagement = Plus Ones x 1 + Reposts x 10 + Comments x 20
Last 100 posts will be used to calculate this metric.
