The biggest news hitting online advertising circles in the last few days (though notably absent from the Adwords blog itself) is that Google is removing something that has been present in Adwords since day 1 - right hand side ads. Right hand side ads (traditionally ad positions 4 through to 8 on the Search Results page) were traditionally the bastion of advertisers who had tight Cost per Conversion/Acquisition limits - here on the right hand side, advertisers could bid low and know that even though they may not get click volume, they could get profit from these cheaper clicks. Why would Google remove the ability for advertisers to execute this perfectly valid strategy?
