• Retargeting by interaction with advertisement. Collect users who have seen your promo post, liked it or shared it with their friends, have seen your commercial, etc.
• Look-alike audiences. Create a look-alike audience using the look-alike technology. A special algorithm will analyze your source database and find VK users who are behaving in a similar way right now.
• Dynamic retargeting. Show ads to users with exactly the same products or services categories as they have viewed on your website or in a mobile application. This tool requires fine tuning, however, it will individualize your ad to the highest possible extent and, therefore, make it most effective.
