Rakuten Shopping steadily improves mobile performance throughout May

“It’s only been since Jan. 31 that Buy.com was rebranded Rakuten Shopping. Many challenges arise when a company changes its name and look. The last thing Rakuten Shopping needs to worry about while working to establish a new brand name in the market is having slow mobile commerce web site page loads or poor site availability, both of which turn off potential customers, says Ken Harker, mobile strategist at mobile and web performance management firm Keynote.”

I beg to differ, Mr. Harker! The LAST thing Rakuten Shopping needs to worry about is a wave of credit card fraud stemming from their poor web practices. That really turns off potential (and current/former) customers.
