Google is the source of nearly 97 percent of all iPhone search traffic, a combination of searches via the Safari toolbar and the Google home page, plus Google's app, according to a new report from advertising network Chitika Research.
Chitika concluded that "if you consider the Google App and Safari to be different sources, Google controls the top two iPhone search engines."
According to the report:
Essentially, the Google App can stand on its own as the second largest search engine on the iPhone. Yahoo! registers as the next search engine behind Google, but its 2.25% falls short of the Google App's reach. Bing is difficult to gauge, as traffic from the Bing app cannot be tracked at this time. However, comparing the number of ratings for the Bing and Google apps in iTunes, Bing traffic could be anywhere between 1% and 4%. At the highest estimate, all of Bing's traffic is still only about half of the Google app.
The Google App accounts for 8.68 percent of Google's iPhone traffic.
