What is the Prebid.js RTD Adapter?

The Prebid.js RTD Adapter is a Real-Time Data module that integrates with Prebid.js to provide contextual targeting signals. It analyzes page content in real-time and delivers IAB-compliant taxonomy classifications, brand safety scores, and sentiment analysis to bid requests-all without using cookies or tracking users.

How does it help with cookie deprecation?

As third-party cookies are phased out, advertisers need alternative targeting methods. This adapter provides privacy-first contextual signals by analyzing the content of the page rather than tracking user behavior. It's fully compliant with GDPR, CCPA, and other privacy regulations.

What is the latency impact on header bidding?

Content is analyzed ahead of time and the results are cached, so in the auction the module reads stored signals. Prebid's auctionDelay setting caps how long the auction waits for them; if they are not ready, bidding proceeds without them. We have not published a latency benchmark for the module, so measure it in your own stack.

Does it support video content analysis?

Yes, the adapter supports multimodal content analysis including text, images, and video. For video content, it can analyze thumbnails, metadata, and transcripts to provide accurate contextual classification.

How do I integrate it with my existing Prebid setup?

Install the package via npm (@mixpeek/prebid), then add it to your Prebid.js RTD module configuration. The adapter automatically enriches bid requests with contextual data. See the GitHub repository for detailed integration guides and code examples.
