Which AdWords Bidding Options Do You Use?

When I started in PPC you could bid in one of 2 ways, by clicks or by impressions. Now there’s automatic and manual bidding… bidding for clicks, conversions, and impressions… bidding for a max or target CPA… using conversions to enhance click bids… . I’ve tested all of these different bidding options in my account but still can’t say which one works “best”.

I know certain situations where I prefer one over another, but wanted to get some feedback from you guys on which bidding options you are using. Below is a short survey about the different bidding options and please feel free to elaborate on your experiences in the comments section. The results will be published next week along with a post about using the bidding options in my accounts. Thanks!
