One of the most frequent words I say when talking about data is monitoring.
We monitor CPC, CPA, ARPU etc for each marketing campaign every day to make sure we make the best value from our marketing investment. When our business is growing and we have many channels, hundreds campaigns in each it’s quite hard to monitor all these time lines. It can totally drive one crazy.
The high level metric to monitor that our business is doing good is to look at marketing spend, revenues or any other metric in the last hour, 24 hours, week or month.
