Increase in CPM

[mike schmitz]

I am not sure why this is happening but I have one site that gets about 40K unique people a day. I have had Adsense on the site for over a year. The CPM for the most part is flat when you look at the stats month to month.

When we launched a second site (the one that is in my profile), we noticed that our CPMs on our first site increased. When we stop sending traffic to our new site and therefore the %of Adsense traffic is mostly on our old site, it's CPM goes back down.

Just to be clear - I am only referring to the CPM on the first site and not the second.

Anyone had any experience of flucuating CPMs when you addded Adsense links to another site?

Quite a few publishers have had experience with fluctuating CPMs even if they haven't added new sites.

Im talking dramatic increases tied exactly to when I start showing Adsense ads on another site.

Your new site must be getting a lot of traffic from search engines. Which is a main reason in increase in CPM.

Hi Mike-

My thought would be, the conversion rates on your new site are good enough that when that site is actively sending clicks to advertisers, and the clicks convert, it's increasing your payout percent due to Google's smart pricing.

Just my theory. :)

So, does this mean that Google's smart pricing collects and reports data regarding an Adsense publisher's performance? I mean, how can Google measure the quality of the clicks your site sends to advertisers (in terms of conversion rates etc.)? Does that mean Google adjusts the payout percentage according to a publisher's individual performance?

Yes I have noticed on a couple of sites a small image saying Google stats. Dunno for sure if it tracks conversion etc.

Yes, google tracks conversions by setting a cookie into the clickies (if you will) browser and then once he/she reaches a certain point on the advertisers site it records it as a conversion. In return telling the adversiter who may or may not use smart pricing to increase its payout to the publisher.

The advertiser may or may not use conversion tracking for its own purposes, but the advertiser doesn't get to set the "smart pricing" discount. Only Google can do that.

It is puzzling for sure - if I turn up the traffic to my site (profile) one at more than $1k per day - it really seems to change the mix on my adsense CPM for the site that I am not advertising.
