Case Study: Large Auto Parts Retailer avoids an 8% drop in purchases with SiteSpect

Large Auto Parts Retailer - Customer Case Study

A large auto parts retailer set out to improve inventory transparency and the customer experience, experimenting with clearer messaging by changing its “Add to Cart” button to “View Details.” The challenge was to know whether this shift would help sales or unintentionally harm conversion.

An A/B test revealed the “View Details” variation caused an 8% drop in completed purchases. Because the change was validated (and rejected) through testing, the retailer avoided a sitewide rollout that would have reduced revenue—turning the negative result into a strategic win.
