Conversion Rate Impact Data
The relationship between page speed and conversion rate is well-documented and consistent across studies:
| Load Time | Avg CVR (Desktop) | Avg CVR (Mobile) | Relative Performance |
|---|---|---|---|
| 0-1 second | 3.8% | 2.7% | Baseline (best) |
| 1-2 seconds | 3.5% | 2.4% | -8% to -11% |
| 2-3 seconds | 2.9% | 1.9% | -24% to -30% |
| 3-4 seconds | 2.4% | 1.5% | -37% to -44% |
| 4-5 seconds | 1.9% | 1.1% | -50% to -59% |
| 5+ seconds | 1.4% | 0.8% | -63% to -70% |

How much does page speed affect conversion rate?
Every 1-second improvement in page load time increases conversion rates by 5.2% on average. Pages loading in under 2 seconds convert 2.4x higher than pages loading in 5+ seconds. A site loading in 1 second has a 2.5x higher conversion rate than a site loading in 5 seconds. For a store generating $100K/month, a 1-second improvement translates to $5,200/month in additional revenue.
What is a good page load time for Shopify stores?
A good page load time for Shopify stores is under 3 seconds. The median Shopify store loads in 3.8 seconds on mobile. Top-performing stores load in under 2 seconds. Google considers pages loading in under 2.5 seconds (LCP) as having "good" Core Web Vitals. Stores in the sub-2-second category see 15-25% higher conversion rates than stores in the 3-5 second range.
How does page speed affect bounce rate?
Page speed has a dramatic effect on bounce rate. Pages loading in 1-2 seconds have an average bounce rate of 9%. Pages loading in 3 seconds see 32% bounce rate. At 5 seconds, bounce rate jumps to 38%. At 6+ seconds, 53% of mobile visitors leave. Each additional second of load time increases bounce rate by approximately 5.6 percentage points.
Does page speed affect SEO rankings?
Yes, page speed is a confirmed Google ranking factor. Google's Core Web Vitals (LCP, INP, CLS) directly influence search rankings. Sites passing all Core Web Vitals thresholds see 24% lower bounce rates from organic search. Pages in the top 10 search results have an average LCP of 1.8 seconds. Mobile page speed is particularly important as Google uses mobile-first indexing.
How much revenue does slow page speed cost?
A 1-second delay in page load time costs the average ecommerce store 7% of conversions, 11% fewer page views, and 16% decrease in customer satisfaction. For a store generating $500K annually, a 1-second improvement would generate an additional $35,000/year. Amazon famously calculated that every 100ms of latency cost them 1% in sales. Walmart found every 1-second improvement generated 2% more conversions.
