All figures are web traffic (website visits); activity inside mobile apps is not captured by web measurement. Share = operator's percentage of the market's measured traffic. MoM = month-over-month change in visits, and the arrow by the rank shows the position change versus last month. Search = the operator's rank by search demand (Google Trends) among the operators shown — compare it with the traffic rank to see whether a brand is pulled by real demand or buys its traffic. Figures aggregate each operator's active domains, including mirror sites.
