How to measure the success of upsell and cross-sell campaigns
Before implementing an upsell or cross-sell strategy, your organization should establish a baseline of its metrics, which can include:
Average purchase value (APV) - The average amount a customer spends each transaction.
Average volume per transaction/units per transaction (UPT) - The average number of items in each transaction.
Customer lifetime value (CLV) - The total amount a customer has spent with the company over time.
Customer retention - The percentage of customers who are still active. Assess this number one month, three months, and six months after a customer’s last purchase.
Next, your team should define what success looks like.
Companies often have data that suggests what an ideal customer is. For example, customers who buy at least three different products have higher retention rates, or customers who spend at least $50 on each purchase are more likely to recommend the brand.
Targeted cross-sells and upsells can keep customers in your ideal range and help your organization reach its goals. Whatever your metric is — maybe you want to increase customer lifetime value or retention, or both — determine a starting point and set a goal based on your company’s larger business objectives.
Your efforts may yield complementary customer engagement boosts, too. For example, you may notice a lift in email open percentage, the number of reactions and comments on social media posts, or more positive customer reviews.
Experiments are essential for testing individual campaign elements and measuring the success of your upselling or cross-selling approach. Aim for a sample size of at least 100 customers who receive a cross-sell or upsell offer and at least 100 who don’t. If the two groups look the same after the test, then your team should try something different or experiment elsewhere.
