Rich media is a type of digital advertising that uses interactive and engaging content to capture the attention of users. It can include a variety of elements such as video, audio, animation, and interactive features.

Rich media ads are typically more complex and require more resources to create than traditional banner ads, but they can be more effective at driving engagement and attracting attention. They are often used in display advertising and can be served through a variety of ad servers and demand-side platforms (DSPs).

There are many different types of rich media ads, including expandable banners, overlay ads, and in-banner video ads. On social media, rich media ads appear in a user's social media feed and may include interactive features such as polls, quizzes, or carousels.

Rich media ads can be effective at driving engagement and conversions, but they can also be more expensive to create and require more technical resources to implement. Advertisers should carefully consider the costs and benefits of using rich media in their campaigns.
