What Is the Marketing Funnel and How Does It Work?

The marketing funnel is a model that describes the journey a potential customer takes from first encountering your brand through to making a purchase. It’s shaped like a funnel because many people enter at the top — becoming aware of you — but only a portion move through to the point of buying.

Understanding the funnel helps you create the right content for the right people at the right moment. A visitor who has never heard of you needs something different from someone who is actively comparing you to a competitor. Treating both the same way is one of the most common marketing mistakes.

The three stages: TOFU, MOFU, BOFU

Top of funnel (TOFU) is the awareness stage. People here have a problem or question but may not know your business exists. The content that works at this stage is educational and broadly useful: blog posts, guides, social media content, videos, and podcast appearances. The goal is to attract attention and be helpful — not to pitch your services.

Middle of funnel (MOFU) is the consideration stage. People are now aware they need a solution and are evaluating their options. Content that works here includes comparison guides, detailed case studies, webinars, email sequences, and in-depth how-to articles. You’re building trust and demonstrating that you understand their situation.

Bottom of funnel (BOFU) is the decision stage. People are ready to buy and are choosing between a shortlist that probably includes you and one or two competitors. Content here includes testimonials, free trials, demos, proposals, and clear pricing pages. The job is to remove the final doubt and make it easy to say yes.

Building content for each stage

Most small businesses have plenty of BOFU content — their services page, contact form, and maybe a few testimonials — but little or nothing at the TOFU and MOFU stages. This means they can only attract people who are already ready to buy, which is a small and competitive slice of the market.

Adding TOFU content — a blog, a YouTube channel, social posts answering common questions — brings in people earlier in their journey. Over time, as they consume more of your content, they move through to consideration and eventually decision. This is the principle behind content marketing: earning attention rather than paying for it every time.

Email marketing is particularly effective at moving people from MOFU to BOFU. Capture email addresses with a useful lead magnet at the TOFU stage, then nurture those subscribers with a series of emails that build trust, share expertise, and gradually introduce your services.

Measuring funnel performance

Each stage of the funnel has its own metrics. TOFU metrics include organic traffic, social reach, and content views. MOFU metrics include email open rates, return visits, and time on page. BOFU metrics include enquiry rates, conversion rates, and cost per acquisition.

If you have strong traffic but low enquiries, the bottleneck is likely in the MOFU stage — people are finding you but not being persuaded. If you get plenty of enquiries but few convert to sales, the bottleneck is at BOFU. Identifying where people are dropping off tells you where to focus your attention.
