Facebook: Trump paid higher ad rates than Clinton during campaign

Facebook is pushing back on a claim that was quoted by Hillary Clinton on Twitter that her presidential campaign was systematically charged more than twice that of the Trump's presidential campaign for advertising rates on Facebook. The company supplied data Tuesday showing that during the general election period, the Trump campaign paid slightly higher rates on most days rather than lower as has been reported.

Why it matters: Advertising prices for programmatic advertising (advertising that is sold through a pricing auction automatically) depend on a campaign's objectives, like targeting, audience size and type of ad used. The Trump campaign and the Clinton campaign clearly used different advertising tactics on Facebook's platform, resulting in different average rates.
