In a recent post, Microsoft extolled the virtues of using its behavioral targeting service profiling mobile phone users. It explained that “campaigns can target individuals based on their online behaviour, including the sites that they visit, the actions they take and the terms they enter into search engines. In the US behavioural targeting on mobiles has already delivered increases in click-through rate of 215% for the fashion and beauty sector, 97% for airlines and 76% for auto advertisers.”
