Which ad format is characterized by its ability to deliver ads relevant to a user's interests?

Online Behavioral Advertising (OBA) is characterized by its ability to deliver ads that are specifically tailored to a user's interests. This ad format utilizes data collected from a user's online behavior, such as their browsing history, search queries, and interactions with content across various websites and platforms. By analyzing this information, advertisers can create targeted advertisements that align with what the user is more likely to engage with, thereby increasing the relevance of the ads.

This approach not only enhances the effectiveness of the ads but also contributes to a more personalized user experience. When users see ads that resonate with their interests and needs, they are more inclined to engage with them, leading to better conversion rates for advertisers. OBA is a pivotal concept in digital marketing as it helps optimize the advertising spend by focusing on the audience that is most likely to respond positively.

In contrast, interstitial ads are typically full-screen ads that appear at transition points during a user's interaction with an app or website, but they do not inherently focus on user interests. Banned ads refer to advertisements that violate policies or regulations and are not relevant to the concept of user interest targeting. Static ads are fixed advertisements that don’t adapt based on user behavior, lacking the dynamic and personalized element that defines OBA.
