What defines a Multi-directional Expanding (MDE) ad in comparison to standard ads?

The defining characteristic of a Multi-directional Expanding (MDE) ad is its ability to expand in response to its position on the page, which allows for a more dynamic and engaging user experience. Unlike standard ads, which typically occupy a fixed space and do not adjust their visual footprint based on the surrounding content or user interactions, MDE ads can adapt and grow in multiple directions. This capability enhances their effectiveness by capturing more attention and providing opportunities for additional content or calls to action within the ad itself.

In contrast to the other options, which focus on limitations or fixed characteristics of ad types, the essence of MDE ads lies in their flexibility and responsiveness. Standard ads do not have the same expanding capabilities, which can result in less user engagement compared to MDE ads that evolve based on their context on the webpage. Expanding based on positioning allows MDE ads to better integrate with the overall design of the site and can lead to improved visibility and interaction rates.
