in our yahoo account we received quality index as 4/5 for an adgroup in which we not received an single impression
on that ad. how it is possible. in most of our adgroup the average quality index as 3/5. how to get above 4/5 for every adgroup. we are using the insert keyword & special offers wording in the ad. in most of the adgroup we used the same ad which we used in adwords(google). in google we are getting the quality score as GREAT but not in yahoo.
what we need to do for getting high quality index in Yahoo?
