Today, eCommerce leaders share a few common goals: to differentiate their brand, attract new consumers, create highly loyal customers, and generate new revenues and profits. 

It’s no easy task. To accomplish these goals, they must keep up with [emerging new trends in eCommerce](https://nacelle.com/blog/five-trends-for-2022?utm_source=blog&utm_medium=website&utm_campaign=theneedforsitespeed) and provide the very best online shopping experiences possible. While there are many different variables that go into creating ideal shopping experiences, one component stands out as a critical must-have: **building the fastest websites possible.**

Brands that ignore site speed, especially mobile sites, are missing out on a real opportunity to improve their business, especially in terms of valuable benefits faster sites can deliver:

1. Faster sites help consumers navigate the entire experience–from opening the home page to selecting the right product–and ensure more people actually reach checkout.
2. Faster sites have lower bounce rates. [Google](https://www.thinkwithgoogle.com/marketing-strategies/app-and-mobile/mobile-page-speed-data/) recently found that a 0.1-second improvement helped retail brands improve their bounce rates by 0.6%. 
3. Faster sites also encourage consumers to stay longer and make additional purchases, critical in increasing basket size and generating higher revenues and profits.

### **Site speed statistics **

In fact, site speed has a direct–and positive–correlation with the eCommerce metrics that tend to matter most, including conversion rates, average order value (AOV), customer loyalty, and ultimately, total sales.

Let’s take a look at key site speed statistics in a number of important categories.

### **Real challenges …**

- 47% of visitors expect web pages to load in two seconds or less ([Kissmetrics](https://blog.kissmetrics.com/wp-content/uploads/2011/04/loading-time.pdf)).
- 57% of consumers will leave a site if it takes more than three seconds to open. Of those 57% who leave, 80% will never return ([SmartInsights](https://www.smartinsights.com/digital-marketing-strategy/barriers-to-online-purchase/)). 
- 40% of consumers say slow speeds will cause them to visit a competitor’s website instead ([Neil Patel](https://neilpatel.com/blog/loading-time/)).
- A one-second delay in page load times results in a 7% reduction in conversions ([Kissmetrics](https://blog.kissmetrics.com/wp-content/uploads/2011/04/loading-time.pdf)).

### **… But real opportunities**

- A 0.1-second site improvement in retail led to an 8.4% increase in conversions and a 9.2% increase in AOV (Deloitte’s “[Milliseconds Make Millions](https://www2.deloitte.com/content/dam/Deloitte/ie/Documents/Consulting/Milliseconds_Make_Millions_report.pdf)”).
- Improving site speed by just one second per page load increases mobile conversion rates by 5.7% ([eCommerce SpeedHub](https://www.ecommercespeedhub.com/site-speed-standard)).
- Mobile sites that loaded in two seconds or less had a 15% higher conversion rate than the average mobile site ([Google](https://www.thinkwithgoogle.com/marketing-strategies/data-and-measurement/mobile-site-speed-conversion-statistics/)).
- Shoppers who experience fast mobile page loads consume more than twice the number of pages as those who wait for slower pages–critical since deeper visits are more likely to convert. ([eCommerce SpeedHub](https://www.ecommercespeedhub.com/site-speed-standard)).
- 95% of mobile users said a fast website would influence them to come back again ([Google](https://www.thinkwithgoogle.com/intl/en-154/marketing-strategies/app-and-mobile/need-speed-evaluating-perception-and-reality-speed-mobile-web/)). 
  
   

### **The chance to differentiate**

- Today the average mobile web page takes 15.3 seconds to load ([Google](https://www.thinkwithgoogle.com/marketing-strategies/data-and-measurement/mobile-site-speed-conversion-statistics/)). 
- The average U.S. retail website takes 6.3 seconds to display mobile content–more than double consumers’ expectations ([Google](https://www.thinkwithgoogle.com/marketing-strategies/app-and-mobile/mobile-page-speed-new-industry-benchmarks/)).
- As of July 19, the average mobile website has doubled in size in less than four years–a trend that is likely to continue [(HTTP Archive](https://httparchive.org/reports/state-of-the-web?start=earliest&end=latest&view=list)). 
  
   

### **What is the best way to improve site speed?**

Headless commerce is a proven way to create lightning-fast websites in order to meet and even exceed consumers’ expectations. Through the use of progressive web applications (PWAs), eCommerce teams can provide a user experience that is similar to a native mobile application. 

Most importantly, PWAs can have a significant impact on site speed and mobile-first functionality. Disruptors are building PWAs to capture the ROI that site speed improvements can generate while unlocking the future-proof potential of the modern commerce stack with Nacelle.

For example, Nacelle customer, Ballsy, decreased its page load speeds from 15.8 seconds to 1.4 seconds with a new headless PWA–leading to a 28% increase in conversions.
