Sundar Pichai said traditional search will gradually end up inside an agent layer. Not alongside it — within it. AI agents will perform tasks on behalf of the user, and the search query itself will stop being the entry point.
For a company that earns on ad clicks, the admission carries weight. Either Pichai is candid and Google is preparing a structural shift in its own business, or this is expectation management for investors and regulators.
What the agent layer does to traffic mechanics
An agent layer is a set of AI systems acting on behalf of the user: searching, comparing, booking, buying. The user states a goal. The agent executes it. Search results stay behind the scenes — the agent accesses them, but the human does not see them.
For media buyers and affiliate marketers, this changes the foundation. Organic CTR depends on a person choosing a link. When an agent makes the choice, it relies on structured data, ratings, API availability and machine readability. Not on titles and meta descriptions. SEO does not die, but it shifts: optimising for agent parsing is a different discipline from optimising for humans.
Google earns when a user clicks an ad. An agent does not click — it pulls data directly. If the agent layer absorbs search, cost per click as a monetisation mechanism loses meaning. Google will need to rebuild the ad model around agents: pay per API request, source prioritisation within agent responses, or something the market has not seen. For traffic buyers, CPC from organic and paid search may behave unpredictably over two to three years.
What it means for affiliate tracking
The CPA model rests on a specific user action. If an agent performs that action instead, attribution breaks down: whose conversion is it, and who earns the commission. Networks and advertisers building tracking on cookies and redirects will find that an agent cuts the chain. Server-side tracking and direct API integrations hold up better.
Offers with machine-readable feeds, structured conditions and open APIs gain an edge. An agent can process them without a manual user transition.
Pichai did not name timelines. That does not put the change far off. Google's agent products already exist and are entering search results. Schema.org markup becomes basic hygiene for agent readability, not an SEO option. Content built for user intent rather than keywords matters, because agents work with the goal, not the search term. AI Overviews and Search Generative Experience are already affecting CTR in certain geos.
The agent layer is not an abstract future. Pichai described it as a process already underway. Search does not disappear, but its place in the user journey shifts. Traffic from it will become more expensive or less predictable. Diversifying sources now has practical value.
