Tracking hundreds of millions of ad impressions on its network from September 14 to 18, Chitika compared the Web traffic generated by the the Kindle Fire HD and the Nexus 7.
Only five days after its debut, the Kindle Fire HD racked up 11 percent of all Kindle Fire ad impressions in the U.S. and Canada. That means the new model is doing nicely in comparison with its predecessor. However, the new Kindle Fire's initial adoption rate doesn't quite hold a candle to that of the Nexus 7.
Measured against all tablet traffic over the same week, the Kindle Fire HD's share was less than 1 percent. Although obviously low, that's similar to the percentage seen by Chitika for almost all new non-iPad tablets during their first week.
Looking strictly at the share of overall Web traffic, the Fire HD has so far grabbed a 3.5 percent slice, while the Nexus 7 leads with 68.5 percent. Eyeing the two tablets, Chitika believes the Fire HD has a lot of ground to catch up if it's to make any headway against the Nexus 7.
