Can a page that has a high CTR or conversion rate be considered a poor quality landing page? In short, yes. Though the Quality Score incorporates the CTR of your keyword, when our system is specifically evaluating your landing page quality, it does not consider the CTR of your keywords or any conversion tracking or Google Analytics data in the account. Instead, it's focused on the actual content and relevance of your landing page to a user who clicks on your ad and ends up on your site. It is well worth noting that not all ads with a high CTR provide a good experience for users. For example, an ad may promote a new home for sale in San Francisco for the query 'San Francisco homes', but after clicking on the ad, the user is taken to a page that shows houses in Seattle. This is not a particularly good experience for the user -- but the ad itself could still be highly relevant to the keyword, and thus is likely to have a high CTR. http://payperclick-india.blogspot.com/
