performance based advertising (Score 1)

> This inherent fuzziness is causing problems for commercial websites, especially online publications desperate to make money from Internet advertising... How can you charge for ads when it's nearly impossible to tell advertisers how many people will see them?' Then use performance based advertising - such as cj.com (or buyat.co.uk in the UK). You don't have to sell CPM (ie clicks) but instead get paid on results (eg. sales generated). This solution has been around for a long long time.
