I've heard grumblings from some on the AdSense side as well as some SEM's that unseasonably warm June weather coupled with the World Cup has slowed down overall search impressions/clicks/conversions by 20% in the month of June.
Anyone have any thoughts on whether or not the weather and th Cup are having such an impact?
I would always expect to see a summer downturn, 20% would not be out of the ordinary.
I would expect to see a drop of about 33% for the summer months (July/August) against Jan/Feb/Mar. It is just the nature of holidays and business, the June drop may be slightly affected by the weather and the world cup - but a lot of what I have seen is that match times are very low but you get a compensating effect before and after.
