Clearly, there has been a huge change in the traditional buying process. In fact, according to Forrester, buyers might be anywhere from two-thirds to 90% of the way through their buying journey before they even reach the vendor. The reason this is happening more and more is because buyers have so much access to information that they can delay talking to sales until they are experts themselves.
In marketing, lead generation is the initiation of consumer interest or enquiry into products or services of a business. Leads can be created for purposes such as list building, e-newsletter list acquisition or for sales leads. The methods for generating leads typically fall under the umbrella of advertising, but may also include non-paid sources such as organic search engine results or referrals from existing customers.
