User profile
A user profile consists of the cumulative characteristics of your target audience. You can use the profile to combine different criteria, such as user interests, income level, family status, and visits to specified locations. By serving ads based on characteristics, you can avoid spending your ad budget on non-targeted impressions.
Crypta technology lets you precisely target your audience. It analyzes users' online behavior and places them in groups. To do this, Crypta technology tracks the behavior of typical representatives of that group. For example, it looks at what words they use in search queries, what sites they visit, and what time of day they go online.
During the ad selection process, characteristics entered in the profile are combined (using the “AND” operator). The more characteristics you add to a profile, the lower your audience coverage.
