In affiliate programs, sites that send you traffic and visitors, have to be paid on the basis of per click or other parameters (such as number of pages visited on your site, duration spent, transactions etc). Most common contractual understanding revolves around payment per click or clickthroughs. Affiliates use tracking software that monitors such clicks using a redirection measurement system. The validity of affiliate programs in boosting your link analysis is doubtful. Nevertheless, it is felt that it does not actually do any harm. It does provide you visitors, and that is important. In the case of some search engines re-directs may even count in favor of your link analysis. Use affiliate programs, but this is not a major strategy for optimization.
