In order to make the most out of your ad campaign, it is highly recommended to display the ad for the longest possible time to allow for the ads exposure to be optimized.
Our ad partners use algorithms to determine the best ads to show to the best audience while also creating a good user experience which is a continuous process of trial and error.
Therefore, the longer you continue running the same campaign, the more effective and successful the campaign will become since the algorithm will attempt to show your ad to the audience who is most likely to purchase your book.
