My eCPM varies from $1 to $4 and all over the places every day. Is $4 CPM good? Is the 400% daily change normal? Is it because smart pricing? I have over 5K page view daily, so I think it is not random.
eCPM from $1~$4 daily is normal, nothing to worry about it. However, $1~$4 ecpm not a good result if you are not in low pay niche
Should I put more ads, to increase, say to $8 CPM, possible? I don't think I can change my niche much, only thing I can do is to increase CTR (more ads) but will that lower CPC?
My eCPM changes more than 400% all the time Adsense earning is not stable. One day, you will earn $1 from 30 clicks, and the next day, you may earn $1 from 1 click. CTR, eCPM etc change all the time.
