As many retailers look to incorporate the mobile web into their marketing and ecommerce efforts, many have let their standalone websites fall by the wayside. It's pivotal that merchants devote their full attention to all areas of their online presence to ensure the best customer experience.

According to a new report from Compuware Gomez, Overstock.com took high honors in regards to the consistency of its website. On Internet Explorer, the page loaded with the average variation of 0.78 seconds, meaning the retail brand was largely providing users with the same experience. Macys.com was top dog when it came to Firefox, with a consistency score of 0.53 seconds.

"The average Internet Explorer consistency score among the 22 retailers measured in March was 1.25 seconds," Compuware Gomez says, Internet Retailer reports. "The same group of retailers produced an average Firefox score of 1.81 seconds."

Load speed is critical when trying to make the best impression on internet shoppers. Separate studies from Google have found that slow loading speeds can turn customers away even before they see the website, which is why the search engine uses load speed as a signal for determining search rankings.
