1) Smart pricing may reduce your earnings per click.
2) Advertisers who track referrals may block your site.
In the long run, it pays to remember that increased clickthroughs are valuable only if they're delivering qualified traffic to advertisers.
does it really matter about location?
One word: YES.
If you have a dynamic site, I suggest that you randomly switch all the pages between two locations (i.e. the same page will show layout A or B randomly)
This will compensate for other variations, such as Adsense roller-coaster, pages with higher CTR or CPC, etc.
Track each layout with a channel, and you will see the difference...
Leave it running for two weeks, ant then judge for yourself.
I had a 70% increase in revenues; there are other people who have an even stronger effect...
Here are my current actual stats (modified a little to stay within ToS) using dynamically-tested layouts as suggested above:
selectPageAdLayout(): calc VPM for NOWHERE is 41c
selectPageAdLayout(): calc VPM for LEFT is 86c
selectPageAdLayout(): calc VPM for RIGHT is 42c
selectPageAdLayout(): calc VPM for RIGHT_DROPPED is 61c
This VPM is a computed/blended eCPM of all the ads on a page including AS and non-AS ads.
So, LEFT (tower) wins hands down for me right now, though a slightly unusual right tower format is in the running too. (Note that there are also non-tower ads, which is why NOWHERE does not have an eCPM of zero!) Note also that these tower ads include a large chunk of non-AS CPM towers.
Please note that the numbers do change a bit, possibly due to ad blindness setting in for a particular layout.
