The Pro version Google Merchant Product Feed Plugin is perfect for medium sized stores with up to 30 products.
Unlike alternatives, Google Merchant Product Feed (Pro) allows you to decide whether product variants will be created as individual items within the feed. For example, if you sell a T-Shirt in Red or Blue in the size Small, Medium and Large items for each combination (Small Red, Small Blue, Medium Red, Medium Blue etc) will be created.
The Pro version also gives you the ability to map your custom attributes to Googles Variation Attributes such as Color, Gender, Size, Brand etc.
With the Pro version you can quickly and easily select multiple products to be included in your feed at a category level.
You will receive 3 months support with your purchase to ensure your installation is as easy as possible.
