Earlier this year, Google made a significant change to its Shopping search tab in the U.S. to allow the service to primarily feature free product listings selected by Google’s algorithms, instead of paid ads. Building on that change, Google is today introducing a shift to free product listings in the main Google Search results page in the U.S. Before, it would only showcase sponsored links in its “product knowledge panel.”

This panel appears when a Google user searches for a product that has matching listings on e-commerce website. But until now, those links were paid ads. Google says, starting this summer, these panels will instead feature free listings.
