Third-party data can help improve targeting by giving access to information about users outside your own website or app. This kind of data comes from outside sources and often includes details like user interests, online behavior, or buying habits. By using it, you can show your ads to people who are more likely to care about what you’re offering. For example, if you're promoting fitness gear, third-party data might help you reach people who often visit health and workout sites. It also helps you reach new audiences you haven’t connected with yet. Combining this data with your own can improve your results and reduce wasted ad spend. Has anyone here tried this approach before or thought about it?
