I tried to change to campaign optimizer, but since that day I got no impressions and clicks. And I visit the improvement oppourtunity page, it said can't offer me a proposal. Does anybody try the campaign optimize settings? How is it?
You need to have a certain expenditure before you start getting genuine help from Google employees i'm afraid. I looked at it, but deemed it as not that great. At the end of the day, there is no beating taking time to go through everything yourself. It it sounds too good to be true, it probably is!
I wouldn't bother with it. It seems to optimise revenue for Google by coming up with obscure key words and tells you to restart paused or deleted campaigns.
I have had Google recently optimize a number of our campaigns with some success. they have added more keywords, ad types and changed my CPC default bid. The outcome has been good and I have since been achieving a lower Cost per Conversion for these campaigns
