Build-to-order (BTO) vehicle ads are now serving in a limited capacity in nine countries, according to the latest Google Ads help documentation.
BTO ads are operational for a small percentage of traffic in the United States, Germany, France, Netherlands, Italy, Spain, United Kingdom, Australia, and Canada. Advertisers in other regions can still upload BTO ads, but they will not be served until the format becomes available in their specific country.
The landing requirement for these ads has also changed from the initial configurator step to the one that matches the attributes submitted in the data source, enhancing targeting precision for customizable vehicles.
