Generating inquiries from potential clients or customers is referred to as lead generation. As this is traditionally the first step in the internet marketing sales process, both quality and quantity are very important. Since you will have a certain number of leads that will be non-buyers, it is the leads that you have a higher probability of closing (qualified leads) that should be the focus of lead generation. As a result, being able to evaluate your lead generation initiatives becomes one of the more important steps in the process.
