Per-Use Revenue Sharing for Publishers
Will Bryk, CEO of Exa, on building search for AI agents
This points to a very different business model for AI search, where the search engine is less like an ad marketplace and more like a usage meter for information. In that setup, an app pays each time it asks for web knowledge, the search provider tracks which sources helped answer the request, and some of that revenue can flow back to publishers whose content actually did the work. That is much closer to software infrastructure pricing than classic search ads, and it gives publishers a direct economic reason to make content that agents want to retrieve and cite.

Exa is already sold this way. Customers like Ecosia pay on a query based plan, around $300,000 per month in one deployment, which means the economic unit is not an ad impression but a paid retrieval call inside another product. That makes source level payout technically imaginable because usage is already metered at the query level.

The closest market analogue is licensing and publisher programs. OpenAI has signed content deals with publishers like Condé Nast and Guardian that emphasize attribution and paid access to journalism, and Perplexity has built a publisher program around licensing and new publisher revenue streams. The missing step is moving from fixed partnership deals to automatic per use revshare.

This model also changes what content wins. Exa describes its index as a curated subset of higher quality pages, and customers use it to pull full text from large numbers of results for agents and summaries. If AI search rewards the sources that repeatedly supply clean, relevant answers, publishers start optimizing for usefulness to machines and humans, not just clicks from headlines.
Over time, AI search is likely to split into two layers. One layer sells query volume and retrieval to apps and agents. The other layer signs or automates payouts to the content owners that make those answers possible. If that market matures, the strongest search engines will not just rank the web, they will become the payment rails between applications and publishers.
