I do, however, see declines in late fall, at a time when e-commerce sites are likely to booming with the approach of the Christmas season.
Seasonal spikes and dips vary from site to site, since they're influenced by topic and the audience's mindset.
Why? I suspect it's the post holiday blues, credit card catch up from Christmas, mid winter vacations, etc. In other words many different reasons from many different people, each person having their own reason.
If it's CPC, wouldn't the system automatically reduce spend when there are fewer people clicking?
To some extent, but advertisers go on vacation, too. Mom-and/or-pop advertisers may simply take a few days off from advertising while they visit Grandma, go skiing, or get drunk in Cancun.
