Every fraction of a second your store takes to load costs you real money in lost conversions, higher bounce rates, and lower search rankings. This comprehensive data resource compiles 50+ sourced statistics quantifying the precise financial impact of page speed on ecommerce performance, with specific benchmarks for Shopify stores. > **Key Statistic:** Every 1-second improvement in page load time increases conversion rates by 5.2% on average. A 0.1-second improvement in mobile site speed increases conversion by 8.4% for retail and 10.1% for travel. For a store generating $100K/month, a 1-second speed improvement generates $5,200/month ($62,400/year) in additional revenue.
