Para mim a pergunta devia ser "inbound and outbound lead generation": Lead generation, or lead gen is a marketing tool used, particularly in internet marketing, to generate consumer interest or inquiry into products or services of a business. Leads can be generated for a variety of purposes - list building, e-newsletter list acquisition or for winning customers. There are many tactical methods for generating leads. These methods 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. Businesses strive to generate 'quality' leads. Quality is usually determined by the propensity of the inquirer to take the next action towards a purchase.
