The Marketing Funnel Explained: From TOFU to Advocacy

The Marketing Funnel Explained: From TOFU to Advocacy

That neat, cone-shaped marketing funnel diagram you see in every PowerPoint presentation is a lie.

It’s comforting fiction; we tell ourselves to impose order on the magnificent chaos of attracting human beings and convincing them to buy something. It promises a clear, predictable path from A to B.

But your customer doesn't live in a diagram. They live in the real world, where they get distracted by their kids, see a competitor's ad, ask a friend for a recommendation, and forget they visited your website.

The marketing funnel isn't a map of your customer's journey. It's a map of your tasks. And understanding that distinction is the difference between frustration and growth. 

The goal isn't to worship the model; it's to understand its psychology so you can build a system that works in the messy business reality.

What Is a Marketing Funnel (And Why Do People Swear By It?)

A marketing funnel is a model that represents the theoretical journey a potential customer takes, from the first moment they hear about your brand to the point they become a paying customer.

It's called a funnel because you have a broad audience of potential customers at the top. Some will drop off as they move through the stages, and only a smaller number will emerge at the bottom as buyers.

The most common, practical way to label these stages uses simple acronyms.

• Top of Funnel (TOFU): Awareness. This is where a person, who has a problem, first becomes aware that you exist as a potential solution. They aren't ready to buy; they're just gathering information.
• Middle of Funnel (MOFU): Consideration. Now, they're actively researching. They're comparing your solution to others, reading reviews, and figuring out who to trust.
• Bottom of Funnel (BOFU): Decision. They've decided to make a purchase. They just need to finalise their choice. This is where they look at pricing, request a quote, or sign up for a trial.

The concept is wildly popular for a simple reason: it gives us a feeling of control. It helps marketers and business owners organise their activities and justify their budgets. It's a simple story to tell your team or a bank manager. But a simple story isn't always the actual story.

Pet Peeve #1: The AIDA Model is a 125-Year-Old Antique

You can't talk about funnels for long before someone brings up AIDA. It stands for Awareness, Interest, Desire, and Action.

It's often presented as a timeless marketing principle. It's not. It's a historical artefact. Elias St. Elmo Lewis, an American advertising advocate, developed the concept around 1898. He tried to explain how a print ad or a door-to-door salesperson could guide a prospect's mind.

Think about that. This model was designed for a world without the internet, Google reviews, social media, and a thousand competitors just a click away.

The fundamental flaw in AIDA is that it assumes a passive customer. It frames the process as the marketer does to the prospect, pushing them from one state to the next. But modern customers aren't passive. They pull the information they need when they need it. They might see one of your blog posts (Awareness) and jump straight to your pricing page (Action). They might bounce between Interest and Desire for six months, reading every review site before they ever contact you.

AIDA is a valuable piece of history, but if it's the foundation of your modern marketing strategy, you're building on sand.

A Practical Look at the Funnel Stages (With Real-World Examples)

Forget forcing customers into boxes. A better way to use the funnel is as a framework to organise your marketing activities. Are you creating content for people who don't know you exist? Or for people who are about to make a decision?

Let's break it down.

Top of Funnel (TOFU): Getting on the Radar

The goal here is education, not a hard sell. You are trying to be the most helpful answer to a question your potential customer is asking. You're building awareness and subtle authority.

• Common Tactics: Blog posts answering common questions, Search Engine Optimisation (SEO) to appear in Google results, helpful social media updates, or instructional YouTube videos.
• Example (A Local Plumber): They write a blog post titled, “5 Signs Your Water Heater Is About to Fail.” Someone with a rumbling water heater searches Google, finds the article, and learns about the plumber's business for the first time. No selling has occurred.
• Example (A SaaS Company): A project management software company creates a downloadable PDF, “The Ultimate Guide to Remote Team Productivity.” They offer it for free, establishing themselves as experts in the space.
• Key Metrics: Your primary metric is reach. Think website traffic, social media impressions, and keyword rankings.

Middle of Funnel (MOFU): Proving You're the Best Choice

Someone is now aware of you and is actively considering their options. The goal shifts from education to building trust and demonstrating why you are the superior choice.

• Common Tactics: Detailed case studies showing real customer results, webinars that showcase your product or service, customer testimonials and reviews, or a value-packed email newsletter.
• Example (A Local Plumber): Their website features a “See Our Work” gallery with high-quality photos and is backed by 150+ five-star Google Reviews. This social proof sells more than any brochure ever could.
• Example (A SaaS Company): They host a live webinar with a current customer who explains how the software solved a significant problem for their business. This is far more powerful than the company just discussing its features.
• Key Metrics: Now you're looking for engagement. This includes leads generated (like email newsletter sign-ups), how long people spend on your case study pages, and click-through rates on your calls-to-action.

Bottom of Funnel (BOFU): Closing the Deal

Your prospect is ready to buy. Your only job now is to make it as easy and frictionless as possible for them to give you their money. Any confusion or difficulty here will send them straight to a competitor.

• Common Tactics: A “request a quote” form, a free trial, a live demo, or a crystal-clear pricing page with a simple checkout process.
• Example (A Local Plumber): Their phone number is in the top corner of every single page of their website. Their contact form has only three fields: Name, Phone Number, and Problem.
• Example (A SaaS Company): They offer a 14-day free trial that doesn't require a credit card. This removes all risk for the user and gets them using the product immediately.
• Key Metrics: This is all about conversion. The most important metrics are your conversion rate (what percentage of visitors take action) and your Cost Per Acquisition (CPA).

Pet Peeve #2: The Funnel Doesn't End at “Purchase” (And That's Where the Money Is)

This is the single biggest—and most expensive—mistake companies make. They spend a fortune wrestling a customer through the TOFU/MOFU/BOFU stages, process the credit card, and then treat that customer like a stranger.

The data is painfully clear: acquiring a new customer is at least 5 times more expensive than retaining an existing one. The most profitable part of the funnel comes after the bottom.

There are two missing stages.

Stage 4: Retention (The Experience)

The goal here is to validate the customer's decision. You need to make them feel brilliant for choosing you. This is achieved by delivering an outstanding post-purchase experience.

• Common Tactics: A seamless user onboarding process, exceptional customer service that is fast and helpful, a high-quality product that does what you promised it would, or simple follow-up communication to ensure they're happy.
• Example (An E-commerce Brand): The customer receives their product in beautiful, branded packaging with a handwritten thank-you note. A week later, they get an automated email—not to sell them something else—but just to check in and see if they have any questions.

Stage 5: Advocacy (The Flywheel)

The ultimate goal is to turn your happy, retained customers into a volunteer marketing department. These people will leave glowing reviews, refer their friends, and defend your brand online.

• Common Tactics: Actively asking for reviews and testimonials, creating a referral program that rewards both the advocate and the new customer, featuring user-generated content on your social media, or building a community (like a Facebook group) for your best customers.
• Example (An E-commerce Brand – Gymshark): The activewear brand built a billion-dollar empire not just on good products, but by turning its customers into idols. They reposted photos of real people wearing their gear, creating a powerful social proof and desire cycle.

This post-purchase loop is so powerful that HubSpot famously re-imagined the entire funnel as a “Flywheel.” In their model, the momentum of delighted customers powers the acquisition of new ones. It’s a more innovative way to think about growth.

Pet Peeve #3: Your Customer Isn't a Ball Bearing in a Chute

The most dangerous part of the funnel lies in the idea of linearity. People don't move neatly from stage to stage.

Google's research team calls the modern reality “The Messy Middle.” It's the chaotic, unpredictable space between first becoming aware of a product (trigger) and actually buying it (purchase).

In that space, people bounce around. They might:

1. See one of your Instagram ads (TOFU).
2. Forget about you for three weeks.
3. Read an article on a third-party review site that mentions you (MOFU).
4. Visit your pricing page and then leave (BOFU).
5. Get an email from you a week later because they signed up for your newsletter ages ago (MOFU).
6. Finally, click a link in that email and purchase (BOFU).

What does this messy reality mean for you? It means you can't rely on one channel. Your brand must be consistently helpful and credible across multiple touchpoints. It's not about forcing someone down a predetermined path. It’s about being the best answer whenever and wherever they happen to be looking.

This is where a cohesive brand and an innovative digital marketing strategy become non-negotiable. You can't be everywhere, but you must show up in the right places with a consistent message.

How to Build Your First, Ugly Marketing Funnel

Forget perfection. Let's get practical. You can map out a basic, functional funnel in an afternoon.

Step 1: Define Your Customer's Problem. Stop thinking about your product. Think about their pain. A person doesn't wake up thinking, “I need to buy a quarter-inch drill bit.” They think, “I need to hang this picture.” Your marketing starts there.

Step 2: Map Their Journey (Backwards). Start at the moment of purchase and work your way up.

• What do they need to buy from you? A “Buy Now” button or a “Request Quote” form. That's your BOFU.
• Before they click that, what do they need to believe? That you're credible and the best choice. They need to see testimonials or case studies. That's your MOFU.
• Before they look for proof, how would they even find you? They'd search Google for a solution to their problem. They need to find a helpful blog post or video. That's your TOFU.

Step 3: Choose ONE Channel for Each Stage. Don't try to master 10 platforms at once. Start small.

• TOFU: Write three helpful blog posts that answer your customers' top three questions.
• MOFU: Create a straightforward page on your website with your three best customer testimonials and some photos of your work.
• BOFU: Make sure your contact page is dead simple and your phone number is easy to find.

Step 4: Measure One Simple Metric. Don't get lost in analytics. Track one number that matters. It could be the total traffic to your blog posts, the number of clicks on your “testimonials” page, or the number of contact forms submitted—just one.

Step 5: Add the “After-Sale.” Plan for what happens after the transaction. Draft a simple email template you can send one week after a sale, asking if they're happy and (if they are) gently asking for a review. This alone puts you ahead of 90% of your competitors.

Your Funnel Isn't Working. Now What?

The funnel model can be a diagnostic tool when things aren't working. Find the leak.

• Problem: No Traffic (Leaky Top). If nobody is visiting your site, your TOFU is broken. You need to work on your SEO, create more relevant content, or find better ways to promote it.
• Problem: Traffic but No Leads (Leaky Middle). If people visit but never contact you, your MOFU is broken. Your website might be confusing, you lack social proof like reviews, or your message may not be compelling.
• Problem: Leads but No Sales (Leaky Bottom). If you get inquiries but can't close them, your BOFU is broken. Your pricing could be unclear, your quote process too slow, or your final offer isn't strong enough.
• Problem: Sales but No Repeat Business (No Bottom!). You are completely ignoring retention and advocacy. Your post-sale experience is likely nonexistent or poor.

Fixing these leaks often comes down to clear communication and professional design. If your website is confusing or untrustworthy, it's poisoning the entire system. Getting an expert opinion can save you a fortune in the long run. Feel free to request a quote if you think your website is the source of the leak.

Final Thought: Ditch the Funnel, Build a System

The marketing funnel diagram is tidy. Business is not.

Use the stages—TOFU, MOFU, BOFU—as a simple way to organise your marketing tasks. It's a helpful checklist.

But don't believe your customers follow that neat path for a second. They are chaotic, well-researched, and sceptical. Worship them, not the diagram.

Your goal is not to build a perfect, linear funnel. It's to create a reliable system where every part of your marketing—from the headline on your homepage to how you answer the phone—works together to earn a customer's trust. Build a system that makes them feel so smart for choosing you that they can't help but tell everyone they know. That's a funnel that works.
