Lucid nailed it with “But mainly, for ads to appear at the top, your QS needs to be 7 or more and of course, your ad rank – QS times bid – has to place you there.”
Advertisers must have a Quality Score of 7 or higher for their ads to appear in the top ad positions. If you do not see ads in the Top ad position it is because of none of the advertisers, with the top 3 ad rank scores, have quality scores of 7 or higher.
