Within the Mail.ru ecosystem, what is the *most directmethod to exclude users who have already converted from seeing further acquisition-focused advertisements?

The most direct method to exclude users who have already converted from seeing further acquisition-focused advertisements within the Mail.ru ecosystem is to create an exclusion audience based on conversion tracking and then apply this exclusion audience to your acquisition campaigns. Conversion tracking involves using the Mail.ru Pixel or server-side tracking to record when a user completes a desired action, such as making a purchase, submitting a form, or signing up for a newsletter. Once conversion tracking is set up, you can create a custom audience of users who have triggered this conversion event. This audience represents those who have already converted. To prevent these users from seeing acquisition-focused ads, you then apply this 'converted users' audience as an exclusion audience to your campaigns that are aimed at acquiring new customers. By excluding this audience, you ensure that your acquisition budget is not wasted on users who have already completed the desired action, and you can instead focus on reaching new potential customers. This ensures a higher return on investment (ROI) and a better user experience by avoiding irrelevant advertising.
