I've always enjoyed fairly good RPM with Youtube monetization via adsense, but over the course of the past couple years my RPM has been slowly declining. November used to be a great month, with RPMs breaking $4 regularly. In 2011 (the good old days) I had days in December where I got $9 RPM with 100k views/day monetized with adsense. In 2012 they opened the floodgates and allowed everyone and their mother to become a partner and for me RPM has been decreasing ever since. Anyway, I'm still getting over 20k views/day but at $1 RPM or less per day it just doesn't seem worth it. My traffic mostly comes from several videos on the same subject (Science and Technology but with a little sex appeal) and the views are 95% men who are likely horny. Should I abandon adsense in favor of an adult affiliate offer or CPA network?
