Not all of your site visitors are ready to talk to your sales team or see a demo of your product. Someone at the beginning of the buyer's journey might be interested in an informational piece like an ebook or a guide, whereas someone who's more familiar with your company and near the bottom of the journey might be more interested in a free trial or demo.
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.
