One thing we have just found in our logs which has explained a lot - have you all heard of the mj12bot?
Just found this is spidering all of our nofollow links which explains our strange increases in traffic at random times of the day without the correlating sales increase.(traffic monitored through the nofollow which we always considered to be real people)
The bot has been blacklisted to try and get some clean figures.
