Case Study: Large Auto Parts Retailer achieves order protection (avoids 8%+ order decline) with SiteSpect

Large Auto Parts Retailer - Customer Case Study

A large auto parts retailer discovered that inventory shown on its product listing pages was often out of date, while product detail pages displayed accurate stock. The team hypothesized that changing the listing-page call-to-action from "Add to Cart" to "View Details" (and in one variation also hiding the inventory icon) might drive more completed orders by sending shoppers to the accurate detail pages.

They tested two variations—one that hid the inventory icon and replaced "Add to Cart" with "View Details," and one that kept the icon but changed the CTA—and both decreased orders by over 8%. The results prompted the brand to shift focus to optimizing product detail pages, avoided a larger potential loss, and reinforced the importance of testing new feature and design releases.
