How do we calculate conversion rate and revenue?

On the Metrics page, you can find Conversion rate and Revenue values.

How does that calculated?

When your customers add products to your cart directly from Quiz result page and make a purchase - those products' prices will be added as Revenue.
Revenue - is a real orders value generated by your Quiz. No magic numbers, what you see is what you get!

The conversion rate is calculated by dividing total orders created by the Quiz completions number and multiplying by 100.
For example: 50 orders created / 1000 Quiz completions * 100 = 5%
