Abstract: An online system receives advertisements from advertisers and reviews the advertisement for compliance with policies enforced by the online system. The online system computes scores for each advertisement based on an expected revenue from presenting various advertisement and/or interactions with various advertisements and orders advertisements for review based on their scores. If a predicted time for the online system to review an advertisement is greater than a threshold amount of time, the online system allows the online system to be evaluated for presentation to users. As the online system receives interactions with the advertisement, the online system may modify the score for the advertisement and modify the order of the advertisement for review based on the modified score.
