A sales funnel is the journey a potential customer takes from the moment they first learn about your business to the point where they make a purchase. Each stage of this journey requires a different message, a different type of content, and a different objective.
The problem? Most businesses focus exclusively on the top of the funnel — getting traffic. They invest in ads, SEO, and social media, but have no system to turn visitors into leads and leads into customers. The result: money spent on traffic that never converts.
In this guide, we show you how to build a complete funnel from scratch, with the right tools at each stage. This isn't abstract theory — it's an actionable plan you can implement immediately.
The Funnel Framework: TOFU → MOFU → BOFU
Before you start building, you need to understand the 3 stages of any sales funnel. Each stage has a distinct purpose and requires specific tactics:
TOFU (Top of Funnel) — Awareness
Goal: attract the attention of the right audience. People don't know you yet and may not even realize they have a problem you can solve. Tactics: blog posts, social media content, paid ads, SEO, educational content.
MOFU (Middle of Funnel) — Consideration
Goal: turn visitors into leads and nurture the relationship. People know they have a problem and are exploring solutions. Tactics: lead magnets (ebooks, checklists), email nurture sequences, webinars, case studies, in-depth content.
BOFU (Bottom of Funnel) — Decision
Goal: convert leads into paying customers. People are ready to buy but need a final push. Tactics: sales pages, demos, free trials, testimonials, limited-time offers.
The critical mistake most businesses make is jumping straight from TOFU to BOFU — trying to sell immediately to a visitor who just discovered them. Without the MOFU stage, your conversion rate will always be low.
Building TOFU: Attract the Right Audience
The top of the funnel has one purpose: to get the right people on your radar. Not just any traffic — relevant traffic from people who could become customers. There are 3 main channels for TOFU:
Organic content (Blog, Video, Social Media)
Create articles that answer the questions your potential customers are asking. Guides, tutorials, resource lists — anything that helps them understand the problem they have. Optimize your content for SEO to attract long-term organic traffic.
Paid acquisition (Google Ads, Meta Ads)
Paid ads are the fastest way to generate TOFU traffic. Google Search Ads capture people with search intent, while Meta Ads (Facebook and Instagram) work excellently for awareness and reaching new audiences.
SEO and organic traffic
Search engine optimization is the long-term investment. Optimized blog posts, category pages, and evergreen content generate consistent traffic without recurring cost-per-click expenses.
Recommended TOFU tool: Unbounce
Unbounce lets you create lead capture landing pages quickly, without a developer. It includes built-in A/B testing, smart traffic (automatically routes visitors to the highest-converting variant), and templates optimized for lead generation. Ideal for turning TOFU traffic into MOFU leads.

You have traffic. Now you need to turn visitors into leads and build a relationship with them until they're ready to buy. MOFU is the stage where you offer value in exchange for contact information, then nurture that relationship through relevant content.
Lead magnets (ebooks, checklists, free tools)
Offer something valuable in exchange for an email address. A PDF guide, a checklist, an online calculator, a template — anything that solves a concrete problem for your audience. The lead magnet must be directly related to the product or service you sell.
Email nurture sequences
After capturing a lead, don't try to sell immediately. Send a sequence of 5-7 emails that educate, provide value, and build trust. Share case studies, offer practical tips, and position yourself as an expert in the field.
Webinars and demos
Webinars are extremely effective for B2B and complex services. Offer a free 30-45 minute session that solves a specific problem. At the end, present your solution as the logical next step.
Recommended tool: ActiveCampaign
ActiveCampaign is one of the most powerful email marketing and automation platforms available. It includes built-in lead scoring (assigns points to contacts based on their actions), visual automation sequences, advanced segmentation, and a built-in CRM. Perfect for the MOFU stage where you need to nurture leads and qualify them automatically.

Your leads are qualified, they trust you, and they're almost ready to buy. Now you need a flawless conversion experience that eliminates any remaining hesitation. Here are the key elements of an effective BOFU:
Optimized sales page
A good sales page answers every question and objection the prospect might have. Structure: clear problem statement, your solution, concrete benefits (not features), social proof, guarantee, and a strong call-to-action. Every element should push the visitor toward a decision.
Urgency and scarcity (used ethically)
People naturally procrastinate on decisions. Limited-time offers, limited spots, or bonuses available only for a short period accelerate the decision. Important: the urgency must be real, not fabricated. People can sense inauthenticity.
Social proof and testimonials
Reviews, case studies, concrete numbers (customers served, results achieved), client logos. Nothing convinces better than stories from other customers who had the same problem and got results. Video testimonials have the greatest impact.
Payment and checkout optimization
The payment process should be as simple as possible. Reduce the number of steps, use short forms, offer multiple payment options, display security badges, and have a clear return policy. Each additional form field reduces conversion rate by 10-15%.
Recommended BOFU tool: Kartra
Kartra is an all-in-one platform for building complete funnels. It includes a landing page builder, email marketing, checkout and payment processing, membership sites, and analytics — all in one place. No need to integrate 5-6 different tools. Ideal for entrepreneurs and small teams who want a complete funnel without technical complexity.
Try KartraFunnel Metrics to Track
Each stage of the funnel has its own specific metrics. If you don't measure, you can't optimize. Here's what to track at each level:
| Stage | Key Metrics |
|---|---|
| TOFU | Total traffic, Click-through rate (CTR), Cost per click (CPC), Reach |
| MOFU | Lead conversion rate, Email open/click rates, Engagement, Cost per lead |
| BOFU | Sales conversion rate, Average order value (AOV), Customer acquisition cost (CAC), ROI |
The most important metric that few businesses track: stage-to-stage transition rates. What percentage of TOFU visitors become MOFU leads? What percentage of MOFU leads become BOFU customers? These rates tell you exactly where your funnel is losing people.
Common Funnel Mistakes
Even a well-designed funnel can fail if you make one of these common mistakes:
- ●No clear value proposition — if visitors can't understand in 5 seconds why they should choose you, they leave
- ●Too many steps in the funnel — each additional step loses 20-40% of people. Simplify as much as possible
- ●No follow-up for non-converters — without retargeting and recovery emails, you lose leads permanently
- ●Ignoring the mobile experience — over 70% of traffic comes from mobile. If your funnel isn't mobile-optimized, you're losing money
- ●Inconsistent messaging between stages — if your ad promises one thing and the landing page says another, trust disappears instantly
