Which audience targeting option allows advertisers to reach users based on their activity on Facebook?

Behavioral targeting enables advertisers to reach users based on their specific actions and activities on Facebook. This includes tracking user behavior such as website visits, app usage, and interactions with content. Advertisers can harness this data to create customized ads that resonate more effectively with users who have shown particular interests or behaviors, thereby increasing the chances of engagement and conversion.

Demographic targeting focuses on characteristics such as age, gender, and location, while interest targeting relies on users' stated interests and affiliations. Geographic targeting hones in on the users' physical location but does not account for their behavior on the platform. Behavioral targeting uniquely captures the nuanced engagement of users, making it a powerful tool for advertisers looking to optimize their campaigns.
