The marketing funnel is condensing. Buyers are going from discovery to purchase within a single conversation with AI, and if your brand isn't included in that recommendation, you need to get in front of the buyer quickly. 

Evertune's AI Retargeting, built in partnership with Index Exchange and The Trade Desk, lets brands reach high-intent buyers at the exact moment they click out of an AI conversation to verify a recommendation on the open web.

What is AI retargeting?

AI retargeting is the practice of identifying the exact URLs that AI models cite in their responses, then running programmatic advertising on those articles to reach buyers as they click through to learn more.

When AI models like ChatGPT respond to a purchase-related query, they frequently cite sources. Roughly 12% of users click through to those cited URLs (Gener8). That click is a critical touchpoint in the consumer journey, a moment when a buyer is navigating from an AI conversation to the rest of the internet in their purchase path. It's a measurable, high-intent moment.

Why AI retargeting matters for marketers

The audience clicking through on cited sources is demonstrating purchase intent by validating the sources that AI learned from. This behavior signals a fundamental shift in how purchase decisions are verified. And it creates a concrete opportunity: brands can now identify and reach buyers at this exact instant of consideration, on the exact URLs that AI models cite.

How Evertune's AI Retargeting works

The workflow is simple:

  1. Identify: Evertune runs trackers across your category to surface the URLs AI models cite most frequently. This isn't a proxy for intent. It's derived directly from what AI is actually recommending to buyers in your space, across specific prompts or an entire category.
  2. Connect: Evertune shares those source lists directly to Index Exchange to create Private Marketplace deals (PMPs) accessible on any DSP, and to The Trade Desk to create contextual targeting categories. 
  3. Activate. Your media team launches programmatic campaigns on those exact URLs. When a buyer clicks out of an AI conversation and lands on a cited source, your ad is already there.

Ready to reach buyers where the AI conversation ends?

AI retargeting puts your brand in front of high-intent buyers at the exact moment they step from an AI recommendation to the open web. Evertune identifies the sources AI trusts, connects that intelligence to your programmatic infrastructure and makes the activation straightforward. Book a demo to see how it works for your category.
