I am confused. I have several website on different topics. My CPM always varies from a 1-5 on average (yes, sometimes i do get bigger and sometimes smaller). My question is: How is it that i always have this steady (for years) CPM and suddenly it drops for one day. For example: yesterday i had CPM anywhere from a $1-$6 and just few below the $1. Today i have anywhere from 0.5-0.34. How ? Why? I would understand the change in one topic but all websites ? Sounds like something fishy going on with Google. Lately i have this dropping day more and more often. What is going on ?
Same with me. I have only been with adsense six months but my revenue went down 65% or more so far for Jan compared to any other month. Everyone on the official adsense forum is asking the same thing... What happened? I had around 2.5ecpm average which was fine with me. Now I can't get to $1ecpm for an entire day. I have All US traffic. 70% organic. Impressions up, Clicks up, visitors up....earnings down. I thought the first week it was seasonal but now, not so much. I think 1 of 2 things are happening here. Maybe both. 1. Google changed something. Algorithm, Smart pricing, not enough testing an update, policy change...something. I mean if we get paid less, so do they... 2. Advertisers are broke. Economy sucked in some more companies. Christmas is gone. It seems like everyone who had good traffic is down. I sure do hope it comes back though. Today Google has "Site Maintenance" maybe they will fix it.
I have the same problem in January. Ecpm fell 50% from those of December. But last couple of days have seen minor increases. I just hope that they can be normalized soon. Losing lots already.
If there are so many confusing things going on, dont you think Google should announce their changes and fix all the confusions ?
This month my traffic and eCPM is up and I am looking to get one of my highest if not the highest month on record. So its not everyone
