Do people find that their conversion rate on Google Adwords drops dramatically after Christmas.
In the Christmas rush I was converting at about 7% but since Christmas it has dropped week on week this month from 3.5% to just 1.5%. Obviously you get a drop in conversion but by 5.5%, wow.
Do others find this the norm. The site I currently work on is magazine subscriptions. If that helps.
I would start digging into site logs etc to see if you can find out what may cause this. Like keywordguru I would suspect affiliate related stuff but if you are not an affiliate your business should actually go up (I know some of my accounts went North after the affiliates get banner)
