Lesson 6: Enable demographics and interests reports
To begin, navigate to the Admin page. Then click Property Settings.
Under Advertising Features, toggle Enable Demographics and Interest Reports to “ON.” (Only users with Admin access can enable or disable this feature. You can manage this feature in any account where you have admin access.)
This will allow you to view data in your Demographics and Interests reports about the age, gender, and interests of your users.
Note that if you’ve just enabled this feature, it may take a day or two for data to appear in these reports. Also, the reports may not contain any data if your site traffic is very low or you apply a segment that is too small.
