The IPM-score (Interactions per mille) is an expression of how dedicated your fans are.
We measure the average interaction rate per 1000 fans on posts in the last month.
The reason why IPM is an important indicator is that your fans' involvement has a significant influence on your Facebook page's EdgeRank. Edgerank is Facebook's way of assessing the overall performance of pages and can be compared to Google's PageRank. A good EdgeRank is, among other things, important to your Facebook page because it helps determine what share of your fans your posts reach.
