Abstract: An online system presenting sponsored content items to users obtains information about quality of the sponsored content items from users to whom the sponsored content items are presented. For example, a user hiding a sponsored content item or reporting a sponsored content item to the online system describe quality of the sponsored content item. By correlating ratings of a sponsored content item by professional raters with a quality ratio of number of reports of the sponsored content item by users to a sum of number of times the sponsored content item was hidden and the number of reports of the sponsored content item, the online system trains a model to determine the quality ratio for sponsored content items based on characteristics of the sponsored content items. When selecting sponsored content items for a user, the online system penalizes or subsidizes a sponsored content item based on its determined quality ratio.
