X (formerly known as Twitter) bases its ads on a combination of factors, including things you've viewed, clicked on, interacted with, and your overall activity on the platform. Here’s a breakdown of how it works:
Activity-Based Ads: X tracks your interactions on the platform, such as tweets you've liked, accounts you follow, and content you engage with. This data is used to serve ads that align with your interests.
Behavioral Targeting: If you've clicked on certain ads or engaged with specific types of content, X is likely to show you similar ads in the future. This includes retargeting, where ads follow you after you've visited a particular website or shown interest in certain products.
Personalized Ads: X uses information from both on-platform activity and off-platform data sources. This includes websites you’ve visited outside of X, especially if those websites are linked to your X account or you’ve opted into personalized ads.
Random Ads: While the majority of ads are targeted, you may still see some ads that seem random. These could be based on broader audience categories rather than your specific activity.
You can control some of these ad settings by adjusting your privacy and personalization settings in the app.
