Google Product Search is an automatic feature which is turned on when Google thinks you're searching for a product. You may see normal web results for some way down the page, then a row of results for that product from different online shops.
You can also turn it on by clicking 'Shopping' in the filters you will see on the left hand side of the screen whenever you conduct a search.
Product Search is a great way to give your products more exposure, even (or especially) if you have a successul online shop with a stream of visitors, as it can put your products above similar products in search results, where you may not be above them in 'natural' search.
What's more, Google has just made some great improvements to product search:
- multiple filters (left hand side) allow you do narrow your search down, even by category (Google tries to understand the categories your product sits in; it may not always get it right, but it's pretty close)
- you can go to a single product and click 'compare prices' to see its availability in different stores
- you can add products to a 'shopping list' (this doesn't place it in the store's basket; rather, this is like a wish list, and you can go back to your list any time and follow the links to the relevant online shop).
So if you're selling online, why wait? It's easy to set up, and if you need help, that's why we're here.
