My eCPM decreased 16% since Jan 16. Has anyone else experienced this since Jan 16?

[shogun_ro]

Yes, but I filtered some mfa's and back to normal now.

I have a large list of MFA sites but they have new domains every day.

[andrewshim]

yes... maybe abnormally normal fluctuations!

[jomaxx]

I get thousands of clicks every day and this kind of change is completely normal and expected. I can't even imagine how many impressions you'd have to serve up daily before a variation of 1/6 in your eCPM would be cause for alarm. Probably millions.

how do you check that they are MFA site?

I dont know but we used to have $1.3 - $2.5 eCPM all the way from last year, but now ever since mid January, all our CPM gone down to $0.1-$0.5. This gave us hard time as revenue is down 70%.

Anyone experiencing the same thing?

Is it ok to post the ecpm here? Mine is from $3.x to $2.x

4 or 5 days is too short a time frame to be doing performance metrics. I usually do these on a monthly basis.

I see something like this happening to me every month, but every month I kill off the MFA sites, kill all the advertisers that post phone numbers in their ads.

then I wait about 3 days, and I am almost back to normal, I figured that I am being smart priced after the clean up.

what I do next is place some more content and bang, I'm earning more than before.

also don't forget, as your site improves you get more visitors, your click rate drops a bit but your earnings increase. example I use to get 1000 page loads a day with a click rate of about 2% now I get about 3000 page loads per day with a click rate of .9%.

Now my goal is to improve my site and get more visitors and hopefully it will stabilize at .9% or improve. I'm shooting for 5000 page loads per day. then I will work on hot spots and other Google hints on how to improve your earnings.

Decreased by 16%? I didn't know they made fractions that low.
