The Google Product Feed extension allows you to easily configure data to be added to your Google Merchant Centre feed.
Currently this will allow your products to appear in Google’s product search. However please note that Google are currently transitioning Google product search to Google Shopping. In order to appear in Google Shopping store owners will have to submit a compatible feed to Google Merchant Centre and also purchase Product Ads for their products.
The extension allows you to control which data is added to your Google Merchant Centre feed explicitly. You can also set store-wide defaults against the store, specific categories or provide information on specific product pages.
This extension is compatible with the CSV Import Suite extension should you wish to bulk import product data.
