It's a world of contradictions. A while ago Facebook faced a consumer backlash for its Beacon programme, which stored users behavioural data so that it could serve targeted adverts.
So I was surprised to hear that 56% of respondents to a new survey said their social networking experience would be better if marketers pushed more targeted ads (full story).
This reflects the experience of online marketers, particularly in the email sector. Targeting your marketing activitly according to premission and preferences creates huge efficiencies and it also helps to build a relationship with your customers. Get it right most of the time and they'll start to trust your ads - image that!
