Have you ever wondered who funds the online advertisements that are aimed at you? Whether it's due to your marital status, political beliefs, or profession in the oil sector, advertisers are tailoring their messages to different demographics. To promote accountability, consider using our browser extension, which collects the advertisements you encounter on platforms like Facebook and YouTube, all while ensuring your privacy remains intact. Known as Ad Observer, this tool integrates seamlessly with your web browser, allowing you to share the ads you see for inclusion in our public database. Additionally, you have the option to provide some basic demographic details to enhance our insights into the targeting practices of advertisers, but rest assured that we prioritize your anonymity and will never request identifying information. By participating, you contribute to a clearer understanding of the advertising landscape and the influences that shape it.
