Many members choose to add rich snippet code to their online store. How can you test if this code is placed correctly?
Test the correct placement of the Rich Snippet code
To test the correct operation, you can use Google's Rich Results test.
1. In the "URL" field there, enter the URL of the page you want to test (for example, www.webwinkel.nl or www.webwinkel.nl/product).
2. Click on "TEST URL."
3. When you see a green text with green check mark (Page is eligible for rich results), then everything is set correctly.

Common errors
In many cases we see that this error message is caused by the use of an old "Data-vocabulary" code, which is officially no longer supported by Google as of April 6, 2020. When the error message is caused by such an old code you once got from us, we recommend to remove this code and use the rich snippet through the WebwinkelKeur sidebar option.
Proper placement rich snippet code no longer causes "Google Stars"
By activating the "rich snippets via the WebwinkelKeur sidebar" option, review information is structurally passed on to search engines like Google. Google only no longer uses this information to display stars, you can read all about that in the blog about Google's policy change. However, it is still useful to activate this option, since other search engines can still display stars and Google can use the information within its algorithm.
