Slow website is a leaky bucket

Website speed is one key worry in eCommerce for two key reasons. Your marketing RoI drops as customers don't wait for the page to load and your brand suffers as customers hate slow sites

A slow website kills your eCommerce:

  • Your marketing RoI substantially drops as customers don't wait for the website to load
  • Your brand reputation suffers as customers hate slow sites

How did we conclude this? Let's look at the stats

  • One second drop in page load speed reduces the conversion by 26% (Source: Akamai)
  • 70% of consumers think website speed impacts their buying decision from any specific site (Source: Unbounce)
  • As page load time increases from 1 to 10 seconds, the probability of a mobile site visitor bouncing increases 123% (Source: Google/SOASTA Research)

How do we measure and optimize page performance?

Your best buddy here is the Google page speed tool (also called Google Lighthouse). Your website should score well (above 90%) here for both mobile and desktop. The tool measures the following aspects: Performance, Accessibility, Best Practices, SEO, and Progressive Web App. They are collectively termed Web Vitals
