THE MOTLEY FOOL - Feb 10 - Investors considering MeetMe stock should watch: monthly active users (MAUs) and average revenue per user (ARPU). MeetMe will need to continue growing both to stay relevant against its competitors. 8M MAUS (after Skout's acquisiton) is a respectable amount for the size of the company, which has ~200 employees. The thing investors really need to watch, though, is whether or not the company can significantly grow MAUs without acquisitions. In the Q2 and Q3 2016, MeetMe was able to increase its MAUs by 32%. Investors should keep a close eye on the Q4 report due out in March to see if the company is able to keep up this pace. MeetMe also needs to make money from each user. In Q3, ARPU grew to $3.19, a modest increase of 5% YOY. MeetMe serves up ads in its app and says that its advertising cost-per-thousand (CPM) increased 47% YOY in Q3. Meetme also intends to launch in-app purchases for its upcoming live video streams from within the MeetMe app.
