“Does your content Quality Score impact your search Quality Score?
Since this is especially important, we want to make sure that everyone sees the answer to this question, and that answer is ‘No.’ Performance on the content network will not impact your search Quality Score, and vice versa.
Are you applying landing page quality to publisher sites in the content network?
No, this change is focused on improving the quality of ads (and their landing pages) that we serve across the content network. If an advertiser is not providing a high quality user experience on the page to which their ad links, then their ads may stop showing on sites in our content network.”
