The latest Spree Commerce version comes with a fully responsive and easily customizable frontend built for mobile devices in mind. It was designed from scratch implementing several UX best practices (advanced caching techniques, SEO with structured data, Open Graph social preview, Retina optimized images, Srcset fallback to low-res images, images lazy loading, SVG images, and icons). As a result of several types of optimizations, the new Spree UX scores very highly[6] in Google Lighthouse testing, even on low-performance hosting options and with poor mobile internet connections. This potentially leads to more organic search traffic, more conversions, more sales, and more value brought by Spree to the business owners.
