Help ProPublica find out how politicians are targeting you online.
1. If you spot a small blue triangle icon on any online political ad, or the words "Ad Choices," take a screenshot of the ad.
2. Then click on the blue triangle or the words "Ad Choices" to find out which company showed you the ad. Take a screenshot of that, too.
3. Email the screenshots to us at email@example.com. Please include the full URL of the page where you saw the ad.
If the ad asks you to "learn more," visit a website, donate, or sign a petition, please send us a screenshot of that site or petition, as well. (The page where the ad sends you may also be targeted to what advertisers know about you.)
