Structured Data, Microdata, Rich Text, Rich Snippets and Schema.org
Structured data, rich text and microdata is a generic term for information that is "implemented" via hidden codes in the webshop.
The information is structured in a certain way to make it easier for robots to read. The information can be, for example, a product's name, price, description and customer reviews.
We use several different formats/structures to display data in the webshop, including OpenGraph and Schema.org. This means, for example, that customer reviews (if you use that feature) will be included in the structured data of your products and that Google can display ratings (stars) next to your search results.
See and set which data you want to use under "Settings > Search engine optimisation (SEO) > Structured data".
