Google Base is a beta service being offered by Google, and it’s now known as the Google Merchant Center. Here you can upload your entire product data to Google so when people are trying to find your products in Google Product Search they’ll find it. Once you’ve done this, you can drive real buying traffic to your site; with the integrated API for Google Commerce Search you’ll also raise up your PageRank and online relevancy of your store and site. Remember to take advantage of Google’s adwords tools, so you can see what searches will bring you the most sales!
