To show your program on Google, you need:
a program that meets Google's editorial and participation criteria
a supported country: Australia, Brazil, Canada, France, Germany, India, Italy, Japan, Mexico, the Netherlands, South Korea, Spain, the UK or the US
products listed through at least one of free listings, Shopping ads, free local listings or local inventory ads
Watch out: you can only select one supported country per Merchant Center account. In Japan, only point programs are supported.
For marketplaces: you can only set up the program in countries where you already show products. To add a country, first add it to one of your product sources.
