Search engines also provide lead generation options. Any business with a website can appear on a search engine listing for related searches, and visitors can then click a link and be taken to that company's website. However, some search engines also offer a pay-per-click lead generation option. The search engine posts a link to the company's website at the top of the search results form, making it much more likely that prospective customers will choose to visit that website. However, when a visitor does click the link the search engine charges that company a small fee, as opposed to the free 'general' listings.
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.
