landing page evaulation
I had a confusion in mind. Say for example i have 4 campaigns each targeting for the same country and rest components ad groups,ads and keywords are same for 4 campaign. Now how the search query will trigger ads and for which campaign.
example:- If the keyword is "blue jeans" then which ad would trigger for the campaign 1,2,3, or 4. Might be it will show the ad of campaign having similar keyword but good average position. and the quality score is also different for same keyword.In campaign one the qs is 7 and in campaign 3 it is 10.
Re: landing page evaulation
It is a mistake to use the same keywords in more than one AdGroup, much less in more than one campaign, all targeting the same geographic area. Only one ad from your account can show, so the campaign/adGroup/keyword with the highest AdRank will always get the impression. AdRAnk = QS * Max CPC bid.
Get rid of the low QS keywords, keep only the highest QS keyword.
Best of Luck!
