Google Quality Score Fact of the Day:
Posted by Dan Friedman, Google Product Marketing Manager November 17, 2008
“Showing up in a higher position will not benefit your Quality Score. Although higher-ranked ads may typically earn better clickthrough rates, Quality Score is normalized to compensate for performance differences resulting from ad position.”
Note: Sure, CTR is normalized but there are still potential quality score advantages to bidding higher when launching new campaigns, especially if you think you have a quality landing page and offer.
More clicks = more visitors = more potential conversions and a proven conversion rate will lead to a higher quality score faster.
And a positive feedback loop follows, higher quality score = cheaper clicks, and a higher ad position, which once achieved will mean better adwords margins.
