When shoppers search for the best deals online, they want to know the full cost of an item -- including the cost of shipping. In fact, we’ve seen that unexpected shipping costs are a common reason for users abandoning their online shopping purchases. That’s why we’ve been focused on making it even easier for you to showcase the right shipping cost to online shoppers, when they’re ready to buy.
Carrier-calculated rates in
Google Merchant Center are an easy and convenient way to set up accurate shipping rates if you use one of the
supported carriers. In the US, several major carriers recently announced that they’ve begun applying dimensional weight pricing when calculating the rates of their shipments. With this change, package pricing not only factors in the weight of the package, but also its dimensions.
To help you show accurate shipping rates for your items, we’re introducing support for dimensional weight shipping rates in Google Merchant Center. This update lets you define the dimensions of your packages used in shipping taking into account the length, width, and height of a package -- in addition to the weight you already provide.
We’ve created three new attributes that you can add to your product data to provide the dimensions of shipping packages for an item: ‘shipping length’, ‘shipping width’, and ‘shipping height’. Starting today, when you include these attributes, Google will calculate carrier-calculated shipping rates for supported carriers by taking into account dimensional weights. This ensures that calculated rates reflect dimensional shipping rates to provide users with the most accurate costs.
To learn more about dimensional shipping, visit our
Help Center article, and select ‘United States’ at the top.
