Hey people, I have a question here, my eCPM drops from day-to-day, and sometimes, it drops during the day. Like, this morning it says 37$ CPM, but by now (night time), it's at 8$ ish. Anybody knows why?
That happens to me too I have seen it up at around $80 but always finishes at under $1! I always figured it just averaged out over the day but I don't really know.
that is a very high ecpm, must be mean high paying keywords and extremely high CTR. I wouldn't complain if I was getting an $8 cpm.
It is because as the day goes on advertisers run out of the daily budget and the lower paying ads get higher placement thus bringing down the average cpm
