I've found a lot of Adwords spend to be very expensive and unprofitable over the last year and so have had to stop that, or at least trim it considerably.

What has surprised me is that the volume of keywords being searched doesn't seem to change that much, but the number of conversions does. People must spend their life searching for stuff even though they know they aren't going to buy.
