We were each trying to see who could be more pedantic. Not a real insult!That may or may not be true. My opinion is that, in this case, both parties are conducting a dialogue of the deaf. However, I don't think it does anyone much good to be insulting.
Scrambler is technically correct in both points but both cases are subject to provisios, such as the 'phone actually being switched on and the user visiting sites that are being tracked. Roger is correct, in that a reasonably large amount of searching via a tracking site, such as Google, is required for the predictive algorithms to build an accurate picture. The programs used, however, generally try to return some prediction, regardless of accuracy, and that prediction is sold to advertisers.
I discovered this while producing web activity statistical analysis for a large client.
