Here in the UK we have found a new Google ad with a drop-down box, right on top of the other ads, for a certain very popular comparison (am I permitted under the TOS to say which one?)which means that there are now four ads at the top, and in the SERPs only the first three are above the fold. Anyone else seeing this?
I've heard that this has already caused a 20% increase in CPCs. The writing is on the wall for price comparison sites. I wonder how many of them realise that their Adwords spend is feeding the monster which will eventually destroy them?
