i just started a new campaign....a pretty popular one at that. i used methods very similar to what i saw everyone else doing, but with pretty much zero success. i used very targeted keywords, tight ad groups, good ad copy, good CTR, ...but im barely getting any conversions. i dont get how other people are getting #1 and #2 positions and are making conversions and money. at the very least i should be getting a few conversions...a little profit...what is going on here?
