After launching five years ago in the United States, Apple’s search advertising service finally arrived in mainland China this week.

The feature, called Apple Search Ads, lets developers bid on an advertising slot based on users’ keyword search in the App Store, similar to how Google search ads work. JPMorgan previously estimated the giant’s annual ad revenue could top $11 billion by 2025, though the forecast didn’t have a breakdown for the search ad business.
