Despite Kindle Fire, Nexus 7 Sales 98% of Tablet Traffic Still Coming from the iPad

I've written about this before: the discrepancy between tablet shipment/sales and traffic figures. On the one hand you have the IDCs and Gartners of the world reporting tablet "shipments," showing iPad rivals gaining. On the other are the companies reporting the actual traffic they're seeing, which indicates the iPad still dominates all other tablets by a huge margin. 

IDC's Q2 market share data (based on "shipments") argue the iPad has a 68% global share. That's up slightly from Q1.

However, earlier today, digital publishing platform Onswipe put out some data that show that the iPad's share of traffic generated was about 98%. This finding was based on analysis of almost 30 million impressions on 1200 sites earlier this month. 

 

The iPad's nearest traffic competitor, according to Onswipe, is the Galaxy Tab with 1.53% of tablet traffic. 

Ad network Chitika has previously published similar numbers. Earlier this summer Chitika found, based on millions of impressions on its ad network, that the iPad "accounted for 94.64% of all tablet-based traffic." The nearest competitor, again the Samsung Galaxy Tab, had "a lackluster market share of 1.22%."

So while Kindle Fire and other tablet devices (e.g., Samsung Galaxy Tab) have sold millions of units, for some reason these devices are not showing up in the traffic logs of publishers. That could well change in the coming quarter with better Kindle Fire devices and the success of the Nexus 7. But for now there appears to be a strange gap between device sales/shipments and traffic figures being generated by tablets.
