Does anyone know how Compete and Quantcast get their data?
- pclark 17y agoi think they buy ISP data logs
- matt1 17y agoI think they have people to install their browser toolbars, which monitor the sites they visit. Their statisticians then extrapolate the trends to the entire population.
- jasonlbaptiste 17y agoI believe "quantified sites" embed a line of code and that becomes public on quantcast ie- public google analytics. Not sure what else they mash the data up with.
