That such colleague, I am glad you are doing well in that company, however with all due respect I would like to add a couple of doubts and comments.
1. When providing you google adsense ads, what happens if you get banned? do they pay you or not?
2. Considering your last day when you made 30k impressions (if you have 4 ads it would be 7.5k visits), your profit for 7.5k visits was $ 5, that is, your CPM would be $ 0.66, something quite poor for Latam traffic for be honest with you.
3. Entering the web you see very little information in general about the web, there are instructions and how to register, something that does not give much confidence to say.
4. eCPM and CPM are different concepts, the first based on the added impressions and the other on the general visits, but both depend on the CTR and CPC of each ad, I think that this metric would be important for you to take into account, since if your traffic is MX or ES you should be generating more.
I leave these small comments for you to take into account and I think they will be useful for you.
