Choosing the optimal advertising campaign for a specific user

In an advertising system, an administrator can create multiple campaigns, each targeted at a specific audience segment (by gender, interests, age, etc.). The banner text can vary, and the task is to select the text option that best matches the characteristics of the current visitor (for example, using a 'male' version for men), thereby increasing the likelihood of a click. When a user opens the site, their data is sent to the server. It is necessary to implement a mechanism that, based on accumulated information, selects the most suitable advertising campaign for this user.
