Here is the CPM (cost per 1,000 impressions) comparison on Trump campaign ads vs. Clinton campaign ads. Given the recent discussion about pricing, we’re putting this out to clear up any confusion. The chart shows that during the general election period, the Trump campaign paid slightly higher CPM prices on most days.
Prices depend on factors like size of audience and campaign objective; campaigns had different strategies. We want to share more campaign data with researchers, but we’ll need campaigns’ permission, which we’re working on getting.
We’ll be making data like this plus more available to the public when we launch our ads transparency tool in the spring.
