The marketing funnel is a strategic B2B lead generation tool - both for marketing and sales teams to use to classify leads, enhance the nurturing strategy, and more effectively measure conversions. Marketing funnels can be made up of many different stages specific to your individual B2B business but most include some version of the following six sales funnel stages:
Prospect
Lead
Marketing Qualified Lead (MQL)
Sales Qualified Lead (SQL)
Opportunity
Client
The marketing qualified lead and sales qualified lead classifications are the most important designations when it comes to the B2B lead nurturing strategy
