Does Google traffic convert better for Adsense?

When G traffic lost, eCPM tanked

[whbiz]

I am one of the unfortunate webmasters who lost most of their traffic from Jagger. When my site lost 80% of Google traffic end September, my eCPM was cut in half as well as my CTR.

Which makes me think as to whether traffic from non-Google sources such as Yahoo (which became my biggest traffic source) are either not inclined to click as much. I can understand repeat visitors may ignore ads.

Are Google visitors the only ones likely to click on Adsense ads? Does smart pricing takes a bite more if your visitors are mostly non-Google referrals? How important is Google referrals to your Adsense income?

My Google traffic is back up in December. And guess what? My CPM is back up as well.

Anyone else see this thing?

I don't think it's as much to do with G traffic being better
MY GUESS and it is a guess is if pages / site is seen as poor for G algo then a similar algo is applied to adsense i.e. quality of adds in relation to page contents

only a guess from times when G does not like my sites and drops in serps seems to be corresponding drop in quality of adds

The advertisers being shown did not change during those times my site disappeared from the Google SERPs. So I don't think it was a result of sudden poor targeting. I think there's a deeper discount if visitors are coming other from G. Not sure, but can't think of anything else.

When my site lost 80% of Google traffic end September, my eCPM was cut in half as well as my CTR.

Let's assume for an easy example

search engine traffic 10% CTR
repeated traffic from book marks 1% CTR

So when You head
60 visitors from Google
20 visitors from other search engine
20 repeated visitors

expected CTR 8,2%

After the change where You lost 80% from Google
12 visitors from Google
20 visitors from other search engine
20 repeated visitors

expected CTR 6,2%

What could be the mathematics if you bring paid AdWords traffic?

[whbiz]

I wish that the above math was what happened. I would not mind so much a 25% decrease, but 50-60% decrease of both CTR and CPM really hurt. It felt like I was given a double whammy - not only your income was reduced because your traffic decreased, but CPM went down the tank as well. If my traffic decreased but CPM remained constant, then it wouldn't be as bad.

Remember you lost aol traffic as well. AOL visitors convert very well. Also you can only do a good study if you ranked in the same place for the same traffic. Maybe you ranked better in Google for high converting terms compared to low ranking terms in others. There are so many factors involved it is hard to tell for sure. Try to rank in the other se's for what you ranked for in Google and see if the ctr goes back up.
