Silly Question About CPM

   This is a silly question but what factors determine CPM?  I realize it's based on how much advertisers are willing to pay but are ads taken out on a daily basis? I'm just trying to figure out why my CPM varies so much from one day to the next.

      In addition to what has been said here, I personally believe that topic has a lot to do with CPM counts.  For example, topics that more people read would be more likely to have more advertisers bidding to post their ads on those hubs.
      
      If I write about purple turtles, an advertiser is unlikely to care much if his ad shows on that page, but if I write about a diet that is new and has been proven to work, tons of advertisers will want their ads to show on those pages, especially if they sell products that would complement losing weight.

   Just a guess but I would imagine new ads are taken out all the time and that CPM is based on an average so a new ads would affect it in either direction. Perhaps moreso on the downside if people see they can list for less and really drive it down fast. Almost like a stock market. That's what I tell myself anyways. Haha.

   Only staff can give you a definite answer if the ads are billed monthly or if they are daily bids. But, it definitely has something to do with the demographics of your traffic and I assume it also has something to do with how long the ads are being viewed and the number of ads actually being clicked.

      Okay so since traffic and clicks would change daily then CPM would likewise change?  Then is it the average of each person's view or each hub do you think? Either way it must be pretty complex as the ads change based on the viewers  so every article could have countless ads depending on their preferences.  Maybe I'm making this out to be harder than it is and the actual equation is far simpler.
      Edit:  I realized from the report that it must be averaged across articles for each author.

         Yes, it is averaged across all articles for the author.

            My understanding is that the total income is added up and then divided by the number of impressions.  There is no real "average" being taken although the end figure is the same as if it were.

   The ad revenue is now achieved by auction in addition to simple AdSense, using EBDA and Header Bidding. That can make advertisers pay more for ad space since they have to outbid one another. The auctions can cause fluctuations too. I talked to a fellow from SayMedia about it when I was at the Maven conference, but I also posted explanations about each one back in October...

   Good question. If anyone has a crystal ball, please share how we can crack the CPM.
