Anybody have experience with Adwords? I went to a Google meetup the other day, and was inspired to give it a go again.

Let's say you create a campaign. If you then create 10 ads with a $10/day budget, does Google automatically try and figure out which ads perform the best, and therefore show only those ads? In other words, it behooves each person to try as many variations as possible, give a month to test things out, and then press on the best performers?

Just want to make sure my thought process is right here.

Thanks,

Sam
