Abstract: A system and method are provided for assessing an effectiveness of Internet marketing campaigns, and for providing data gathered thereby to subscribers. The assessment data can be gathered in concert with, for example, private sector partners. Different marketing methods are tested, compared, and evaluated for effectiveness in reaching customers. Equations are provided for calculating such values as probability of conversion of a sale and of a success of a marketing campaign, based upon such factors as user anxiety and external motivation. The data can be used to improve a marketing campaign, and also to inform a subscriber base of techniques found to be effective in Internet sales.
