PBP is sort of a cross between a traffic generator and a multi-level marketing scheme, only without the threats that MLM traditionally entails. You’re not absolutely required to sign up under someone, though the program does cost money on a monthly basis. You’re granted access to traffic generation tools, as well as other promotional information and training. The MLM comes in with their referral commissions, which many people use more than the marketing tools themselves. There’s a sizable commission for enrolling new members, as well as seeing them succeed.
Web analytics is the measurement of the behavior of visitors to a website. In a commercial context, it especially refers to the measurement of which aspects of the website work towards the business objectives of Internet marketing initiatives; for example, which landing pages encourage people to make a purchase. Notable vendors of web analytics software and services include Google Analytics, IBM Digital Analytics (formerly Coremetrics) and Adobe Omniture.
