Question: Is there a way to build interactive ads that follow users as they scroll, without relying on third-party data or audience information?

If you want to build interactive ads that track users as they scroll without using third-party data or audience information, Cavai is a good choice. The platform lets brands create personalized, conversational ad experiences for display, mobile and native ads. Its Conversational Bubble and Conversational Video features are designed to increase engagement and sales while protecting privacy with anonymous insights.

Another good option is LensAI, an AI-based advertising platform that analyzes video and image content to place ads within that content. LensAI's in-image and in-video ads are less intrusive and more relevant, targeting content instead of user-level identifiers.
