Behavioral targeting is a marketing strategy that uses data about a user's online behavior to deliver personalized advertisements. This data can include browsing history, search queries, and interactions with websites. By analyzing this information, advertisers can tailor their messages to match the interests and preferences of individual users, increasing the likelihood of engagement. This approach relies on cookies and tracking technologies to gather insights about user behavior. As a result, when users visit different websites, they may see ads that reflect their previous online activities. This method aims to enhance the effectiveness of advertising campaigns and improve the overall user experience.
