The Search Agency looked at the top 100 web-only retailers based on Internet Retailer’s Top 500 list of e-commerce sites in order to evaluate how they’re handling mobile. Specifically, they wanted to see if these sites are more mobile-ready than others.

They found that a shockingly small amount of them (9) were using responsive design, which is what Google apparently prefers. 59 of them used dedicated mobile sites, and the rest simply used desktop sites.

“The average load time for all companies was 2.99 seconds, significantly greater than Google’s recommended 1 second,” the firm says. “The average score was only 2.808 out of 5. The companies with the highest scores were Nasty Gal, eBags, and Zazzle.”

“Sites that ranked higher on the list tended to be more female-oriented businesses,” it adds. “For instance, the highest scoring industries were jewelry, health/beauty, and accessories/apparel.”

It’s worth noting that Google supports sites with dedicated, separate mobile versions just fine. You can read more about mobile optimized sites from the search engine here.
