Amazon has finalized a deal with EU antitrust regulators to settle concerns that its use of non-public data undermines rivals, announcing new measures to level the playing field for sellers in its marketplace.

Through the agreement announced on Tuesday, the US tech giant will treat all sellers equally and make rival products more visible on Amazon’s “buy box,” which generates the majority of purchases on the site.

Amazon will also create a second buy box that displays alternative offers for consumers who decide that speed of delivery is less important to them.
