Question

how does a business assess the impact of their referal program on revenue? positive reviews number of referred customers number of customers sharing invites percentage of total purchases by referred customers

Explanation:

To assess the impact on revenue, we need a metric that directly relates to the revenue contribution from referred customers. "Positive reviews" reflect sentiment but not revenue. "Number of referred customers" and "Number of customers sharing invites" show activity but not revenue impact. "Percentage of total purchases by referred customers" directly ties referred customers' spending to overall revenue, so it's the best metric.

Answer:

Percentage of total purchases by referred customers
