Qualifications to join ad auction

With YDN, ads go through “Ad Auction” and delivered in order of “Auction Rank”: higher auction rank has higher position. Auction rank is determined on bid for ad group / ad, and ‘ad quality’. Therefore, low ‘ad quality’ may result in ads to be not delivered.

See the page below for how ad auction works.

Cost Per Click (CPC)*

CPC* is determined based on bid on ad group / ads along with ‘ad quality’. Therefore, when the ‘ad quality’ is high, you can expect lower click cost.
*For video ads, it refers to cost per view.
