Why is My Google AdSense eCPM Tanking?

AdSenseIt appears Google is heavily compensating for my increased traffic with significantly lower eCPM these days. It is about 60% of what it was a month or two back. Why does Google penalize for increased traffic? Any thoughts? Or does it expect us to give the traffic to someone else like YPN for example?

Any ideas?

My wishlist for Google is that it should make its AdSense share explicit. It allays the fear that it isn’t unfairly depriving us.

Higher CTR may not translate to higher eCPM.
eCPM = CTR X Average Payment per Click X 10

So eCPM is directly dependent upon average payment per click. And even with constant or increasing CTR, your payment may go down because Google is paying you lower per click.

What matters is CTR. Higher CTR = higher eCPM. Traffic and visitors have NOTHING to do with eCPM unless the percentage of people clicking stays the same.

Well I don’t think it is just that. Up to last year my site was making around $110/month, not much but not bad. Since the end of last year I noticed a disturbing trend, the monthly payments dropped down to $50-60/month and now it is down to a pathetic $36 1!!! traffic is the same, site has more info, visitors stable.

I am beginning to believe Google is not giving as much AdSense revenues as before but it escapes me WHY. I am seriously looking for alternatives.

I’ve been curious about that as well. I’ve had a significant uptick in traffic over the last couple of weeks in part thanks to your Translator plugin. However, I’ve been seeing a drop in eCPM as well. Today seems better so I’m not sure if its Google making an “adjustment” or just the types of ads my niche has had available to it. I’ll be keeping an eye on it. I just wish YPN was a stronger alternative. I’ve tried it in the past and it was rather pathetic.
