The Who Targets Me browser extension

Data projects

  • Access crowdsourced political ad data (requires login) and Facebook spending data for any date range.


  • Get daily email notifications when the campaigns you’re interested in launch new Facebook ads, compare frequency and spending data without leaving your inbox.

Political ad data standards

  • Political ad data supplied by platforms lacks sufficient detail and does not follow a consistent format. This project proposes a standard format for this data. Adoption of such a standard would allow political ad data to be combined, compared and new tools built with it.


  • Explore visualisations advertising trends for political parties and candidates.


  • Shows how Trump and Biden targeted and optimised over 500,000 Facebook ads in the 2020 election campaign.


  • Where all of the code for our projects lives.

UK GE2019 Spend Race and Constituency Map

  • Two visualisations of political ad data from the 2019 UK election.

Ideas to explore

  • In-feed fact checking and flagging – making bad ads clearer to Facebook users
  • Advertiser blocking – to allow users to block single, or groups of, political advertisers
  • Expanding beyond Facebook – to provide a wider suite of tools to protect users from low-quality information online
  • Creating an archive of email and SMS campaigns – these are targeted information too.
