Facebook made ad transparency open to the public in May 2018. The Ad Library is a searchable database of all ads that are currently running on Facebook and Instagram. The Ad Library allows anyone to see the ads that are being run by businesses, organizations, and individuals, as well as the targeting information that is being used to reach those ads.
The Ad Library was created in response to concerns about the use of social media for political advertising. In the lead-up to the 2016 US presidential election, there were concerns that foreign actors were using social media to spread misinformation and propaganda. The Ad Library was intended to help people understand who is paying for political ads on Facebook and Instagram, and how those ads are being targeted.
The Ad Library has been praised by some for its transparency, but it has also been criticized for its limitations. For example, the Ad Library does not include ads that are run by political campaigns, and it does not include ads that are run by foreign actors. Additionally, the Ad Library only includes ads that are currently running, so it does not include ads that have been run in the past.
Despite its limitations, the Ad Library is a valuable tool for understanding the use of social media for advertising. It is important for people to be aware of the ads that are being run on social media, and the Ad Library can help people to make informed decisions about the ads that they see.
