We broke down the numbers behind those posts, including how many clicks they got each month and how much they cost. We thought it would be interesting, though, to also pull out the most popular ads that were introduced each month to get a broad sense of which advertising efforts were actually effective. Below, the ad campaigns initiated in each month from June 2015 to August 2017 that received the most overall clicks. The people purchasing the ads were often specific in where they wanted the ads to run and whom they wanted to target, usually based on political views or racial identity. Notice, though, that none of the most popular ads are specifically political, talking about Hillary Clinton or Donald Trump.
