Tracking Chrome for iOS Adoption in the Mobile Market

The purpose of the Chrome for iOS Adoption Tracker is to highlight the share of Web use for Chrome on the iOS ecosystem. To determine the respective web browser shares on iOS, Chitika Insights performed an analysis of the unique iOS impressions seen originating from Safari, Chrome, and Other browsers within the Chitika Ad network. To determine the usage share of each browser, a user agent analysis is conducted across incoming impressions. The following paragraphs further detail the methodology behind the Chrome for iOS Adoption Tracker published by Chitika Insights:

Impressions:

Sample: This study was conducted across a full range of hundreds of millions of impressions from the Chitika Ad Network; coming out of the US and Canada.

Determination: The web browser of an impression can be determined through analysis of the user agent. All user agents of personal computing devices pass a string similar to this (in this case, we are using a desktop impression):

Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11

Reporting:

Top Pie Chart: The percentages reported in the top pie chart represent an aggregate share of Web traffic across all browsers on iOS, with a six hour delay to ensure maximum continuity within the data. These percentages are simply the count of each particular group (Safari, Chrome, and Other) divided by a total count of all Web traffic observed.

Line Chart: The line chart highlights the use of web browsers on iOS across an hourly basis. For each hour, the methodology is the same as in the pie chart, except shown using a time series. For example, if Chrome impressions made up 10% of all iOS impressions on July 12th at midnight, and 11% at July 13th at midnight, the chart would highlight this growth (and show all of the hours in between).
