Google Data Studio Custom Conversion Rate
I need to build a custom conversion rate wioth the following informations:
- I have a custom dimension (traffic on a specific website category) that can take two values
- and the same information (ie website product category) at a product level
I'd like to divide the number of orders where the product category=xyz by the number of sessions where the website category=xyz in order to build a ecommerce conversion rate for each of my two top level categories.
But I can't find a way to do this by using one or several calculated fields.
Would someone be able to help me ?
Thanks in advance
