The first stage in the marketing funnel is known as the "top of the funnel" or TOFU. This is where customers are first introduced to your brand and begin to develop an awareness of your products or services. TOFU marketing strategies should focus on generating leads and building brand awareness. Tactics may include content marketing, search engine optimization, and social media outreach. The goal of TOFU marketing is to introduce potential customers to your brand and create a base of interested leads that can be further cultivated through subsequent stages of the marketing funnel.
