I'm using Conversion Optimizer for most of my campaigns. I've been actively split testing new ads to improve performance. However, since Conversion Optimizer has been turned on I haven't paid too much attention to the performance of my Keywords, since Conversion Optimizer takes this into account when trying to meet my CPA bids. Should I still be looking at the performance on the keyword level, and how do you recommend managing keywords if Conversion Optimizer is being used? Thanks!
