Glossary of Internet Marketing Terms

The various terms that are used in internet marketing can be a bit confusing for newbies, so we're building a glossary of terms below:

CPA - Cost Per Acquisition. The cost to a company of acquiring a new customer. Many affiliate programmes pay out to the affiliate on a CPA-basis meaning that the affiliate is paid when they have enabled the company to acquire a new customer. E.g. the affiliate has promoted a car insurance company on their website, and a new customer has followed the affiliate link through to the car insurance website and signed up for a new car insurance policy.
