I've just accepted a position as a marketing analyst at Ellos (a Swedish e-commerce company). My main responsibilities will be to model customer behaviour in order to direct campains more effectively. Or, as Wikipedia states it:
I just wonder if anyone here works in a similar position and maybe give some recommendations or just ramble about it 
Wikipedia said:
"Consumer marketing research is a form of applied sociology that concentrates on understanding the preferences, attitudes, and behaviors of consumers in a market-based economy, and it aims to understand the effects and comparative success of marketing campaigns."
