When creating lookalike audiences on Mail.ru, what *primarydata source determines the quality and accuracy of the audience expansion?

When creating lookalike audiences on Mail.ru, the *primarydata source that determines the quality and accuracy of the audience expansion is the seed audience. The seed audience is the initial group of users from which Mail.ru identifies common characteristics and patterns to find similar users. A high-quality seed audience is one that is representative of your ideal customer base and contains accurate and complete data. If the seed audience is small, poorly defined, or contains inaccurate data, the resulting lookalike audience will also be of poor quality and may not effectively target potential customers. For example, a seed audience composed of users who accidentally landed on your website or who are not genuinely interested in your product will result in a lookalike audience that is unlikely to convert. Therefore, selecting a seed audience that accurately reflects your target customer profile is paramount for ensuring the quality and effectiveness of your lookalike audience campaigns.
