Google has expanded support for Regional availability and pricing (RAAP) in Google Merchant Center. RAAP is now generally available in 86 countries, with 22 of those now supporting postal code-level targeting.
RAAP allows advertisers to set different pricing and availability based on a customer’s location by overriding national settings. This update helps businesses tailor offers with greater precision, especially in markets with regional pricing differences.
Countries with postal code-level support include the US, UK, Germany, India, Brazil, and Japan. This more granular control lets advertisers apply pricing strategies to specific regions within a country.
