Valve has explained the Steam algorithm troubles that led to smaller games losing traffic. It started with an early October bug that made the “More Like This” section of pages go haywire in favor of “the most popular games on Steam,” and while Valve fixed that shortly after, it kept a change that factored in sales and wishlist popularity—altering which games saw traffic to their pages as a result. It also tested a new algorithm around the same time period, which ended up showing “fewer products to a subset of customers.” Valve says, however, that traffic “recovered” toward the end of October as a result of further changes and “has stabilized since.”
