Hi DP members, Has anyone had experience running split tests experiments using the Adwords ACE system? I have run a few recently to experiment for an account set-up for my blog. Finding them useful for adjusting bids on some key terms for instance a bid of 10% less often seems to equate to little loss in total number of clicks or eve impressions. Keen to hear from the experiences of others and if users are finding other significantly useful applications for this testing platform? Thanks
