With a looming threat that Google will punish sites that do not strictly comply with its specific mobile guidelines, one SEO firm decided to pull out the Fortune 100 list and test everybody on it, using Google's benchmark. Only a half-dozen companies passed (I'd argue it was only five as one of the six was Google itself). No surprise: None of them were retailers. This we didn't see coming, though. One of the worst performers was Amazon (NASDAQ:AMZN).
Most of the retailers did OK, including Walmart, CVS, Costco, Home Depot, Target, Walgreen, Lowe's, Best Buy and Sears. The grocery chains (Kroger, Safeway and Supervalu) did poorly, but mobile commerce is generally a low grocery priority. Then we get back to Amazon, the retailer—let alone e-tailer—that has generally made all matters tech a huge priority. Amazon got beaten up on the ratings partially because the spreadsheet said it didn't have a true mobile site. But it seems to have a true mobile site—a very nice-looking one, too. They do, but it's apparently not done in the way that Google has in mind.
