What is GS1 SmartSearch Schema markup and why should e-commerce sites use it?
By now most of us should be familiar with Schema Product markup which can be leveraged for listings on e-commerce sites.
The benefits of implementing this are serving up your product data in a structured format that is search engine friendly and has the potential to gain rich results such as product rich snippets and rich cards for your product pages.
Now there is a more advanced way to implement Schema Product markup which provides the benefits mentioned above and can also help your products gain additional visibility. Called GS1 SmartSearch, this advanced structured data type includes customer-facing attributes related to food, beverage, tobacco and healthcare, as well as to clothing and footwear.
GS1 SmartSearch also allows you to highlight more elements than a normal Schema Product markup such as Global Trade Item Number (GTIN) details which can help improve the discovery of your products.
