One way that our Facebook Political Ad Collector recruited people to participate was by partnering with a coalition of academic researchers to pay survey participants to install our plugin. This got us a much more diverse user base in terms of politics, geography, age and race – and therefore we got a much more diverse set of political ads.

As a bonus, we got survey data about these survey participants’ demographics, which I used to find the most-seen ad (from Tom Steyer, urging Trump be impeached) and the ads seen by the least polarized audience (ads from the AARP).

This post wrapped up the Facebook Political Ad Collector project for 2018.
