Does having a site with duplicate content but within your own site have a difference on the Quality Score? e.g. you have 10 pages and they all largely have the same content, but you are sending traffic to page 1,2...10 from the same adwords account. This content is not on any other site. Thanks, Jon
The Quality Score will not be affected negatively if you have several of the same keyword in different points of the same account. The keyword will share the same quality score for the whole account even it is repeated in different points of the account. it is exactly the same if you put all 10 pages ads on a same adgroup that has this repeated keyword (the quality score resulting is an average of the quality score on the different ads for that keyword along the account, giving different power depending on the impression for each ad ). it don't makes no difference also if the different landing pages are on the same site or different sites.
