Store speed and conversion: what the data shows
Shopify analyzed performance data from its ecosystem to explore the relationship between site speed and conversion rates. The study found a clear correlation between faster load times and interactivity with higher conversion, while layout stability showed less impact. Although speed is important, the report acknowledges it is one of many factors influencing ecommerce success.
- ▪Nearly 80% of Shopify stores meet all Core Web Vitals thresholds according to Chrome User Experience data.
- ▪For every 100 milliseconds slower a store loads, conversion tends to be about 3.5% lower.
- ▪For every 32 milliseconds slower a store responds to interactions, conversion tends to drop by about 1.5%.
- ▪Cumulative Layout Shift (CLS) showed less correlation with conversion compared to other Core Web Vitals.
- ▪The analysis controlled for outliers and other performance metrics to isolate the impact of each speed factor.
