#7: eBay, 27.1 million+ mobile visitors per month
Online auction giant eBay (NASDAQ:EBAY) admittedly has moved way beyond being a virtual garage sale. There are true e-commerce merchants and used-car sales making the tech company cash, as well as the very profitable PayPal arm paving the way. It’s worth noting, too, that while 27.1 million visitors were sent to eBay via mobile, about 82% came from eBay’s custom app. A few people apparently still are surfing, but eBay clearly is making inroads via software — something that could bode very well as it looks to use PayPal to redefine mobile payments.
