Past 2 days I have 20% more traffic, but CPM dropped?

I have the same CTR even after the traffic boost but my CPM dropped by about 30%. The ads are the same but I see the CPC has dropped by a lot.

 

Happens, It's only a few days so it should bounce back.

 

I have had this happen before many times. The CPC drops and never recovers.

 

Greetings ,

Same for me . Does it happen sometimes ? or regularly ?

 

It is quite normal. When I have high CTR, my CPM will drop. But it is not all the time. Adsense's blog says that they will maximize our earnings, and call us to trust them.

 

I got same click compare to last months but i got 50 % $ less compare to last months !!! what going on have you notice this !

 

even my CTR has suddenly drop....in fact its become nil even as traffic has increased!!
