Case Study: U.S. Auto Parts achieves measurable revenue gains from faster page speeds with Blue Triangle

U.S. Auto Parts - Customer Case Study

U.S. Auto Parts, a leading aftermarket auto parts retailer with three eCommerce brands and more than $300M in revenue, needed to understand how site performance was hurting conversions and where to focus fixes. Despite using tools like New Relic and WebPageTest, Sheng-Te Yang and his team could not quantify revenue impact—so they turned to Blue Triangle and its revenue-opportunity dashboard, deployed quickly via the Blue Triangle tag in Tealium Tag Manager.

Blue Triangle helped prioritize page-level optimizations in dollar terms, identifying the Shopping Cart and Home Page as highest priority, then guided fixes: removing or deferring non‑essential third‑party content and optimizing slow back-end files. The result was a 4-second improvement in DOM Interactive (from ~9s to ~5s), back-end file load improvements of 35% and 49%, and measurable incremental revenue realized within two months—outcomes delivered and validated by Blue Triangle.
