Hi....Sorry if this is a dumb question, but exactly which CTR is used in the whole Google AW matrix that determines ad position, etc.? Is it the overall campaign (all ad-groups combined) CTR avg. as a whole? Or, is it the avg. CTR of each specific ad-group? Or, is it the avg. CTR of each individual keyword and/or ad itself that determines position? F.Y.I., I have 1 local campaign with 18 ad-groups, each has an avg. of anywhere from 8-22 keywords with 4-12 ads (depending on # of keywords). A newbie just wondering. Thanks, Mark
