When a leading retailer of environmentally friendly detergent and dishwasher pods partnered with Addison Applications for Conversion Rate Optimization (CRO), we recognized an opportunity to further enhance their already successful online shopping experience. Their shipping rate seemed high for users who didn't meet the free shipping threshold ($10 dollar shipping on orders less than $29). We wanted to test a lower shipping threshold, while measuring the impact on Conversion Rate, revenue, and shipping profit. The results showed a 6.6% increase in conversion rate across the board, an increase in orders below the free shipping threshold of 49%, which meant that shipping revenue was flat. This was a huge win for getting new customers to try the product, and increase revenue significantly.
