How to Build a Sales Funnel: Step-by-Step Guide

Every online business needs a system for turning strangers into customers. That system is a sales funnel — and if you don’t have one, you’re leaving money on the table.

The good news, however? You don’t need a marketing degree or a five-figure budget to build one. In this step-by-step guide, we’ll walk you through how to build a sales funnel from scratch, including the exact tools you need at each stage, common mistakes to avoid, and how to optimise for maximum conversions.

If you’re new to the concept, start with our guide on what a sales funnel is and why it matters. Already familiar? Let’s build.

What Is a Sales Funnel? (Quick Recap)

In simple terms, a sales funnel is the journey a potential customer takes from first discovering your business to making a purchase. It’s called a “funnel” because many people enter at the top (awareness), but only a fraction make it through to the bottom (purchase).

The classic stages are:

• Awareness — They discover you exist
• Interest — They engage with your content
• Decision — They evaluate your offer
• Action — They buy

Ultimately, your job is to guide people through each stage as smoothly as possible. That’s exactly what a well-built funnel does. For a deeper dive into each stage, see our complete sales funnel guide.

How to Build a Sales Funnel from Scratch: 7 Steps

Step 1: Define Your Target Audience

Before you build anything, you need crystal clarity on who you’re building it for. After all, a funnel that tries to speak to everyone converts no one.

What to do:

• Create a customer avatar. Document their age, job title, income level, goals, frustrations, and where they spend time online.
• Identify their primary pain point. What problem keeps them up at night? Your funnel needs to address this directly.
• Research where they hang out. Are they on LinkedIn, Instagram, YouTube, or searching Google? This determines your traffic strategy.
• Study the competition. For instance, sign up for competitors’ funnels. Note what works, what doesn’t, and where you can differentiate.

Tools for audience research: Specifically, Google Trends (free), AnswerThePublic (free tier), SEMrush (keyword and competitor research), and social media analytics on the platforms your audience uses.

Pro tip: Additionally, survey your existing audience or customers if you have them. Real answers from real people beat assumptions every time.

Step 2: Create an Irresistible Lead Magnet

A lead magnet is a free resource you offer in exchange for someone’s email address. In other words, it’s the bridge between “stranger” and “subscriber” — and it’s one of the most important elements of your funnel.

Effective lead magnet formats:

• Checklists and cheat sheets — Quick wins that solve a specific problem (e.g., “The 10-Point Sales Page Checklist”)
• Templates and swipe files — Ready-to-use resources they can plug into their business
• Free guides or mini ebooks — 5-15 pages covering a focused topic in depth
• Video training or webinars — Especially powerful for high-ticket offers
• Free trials or demos — Let the product sell itself
• Quizzes — Also highly engaging and interactive, with personalised results

The golden rule: Above all, your lead magnet must deliver a quick, tangible result. If someone downloads it and thinks “that was actually useful,” you’ve earned their trust — and consequently their attention for what comes next.

Tools for creating lead magnets: Canva (design), Google Docs (content), Beacon.by (ebook formatting). For delivery, most funnel builders like Systeme.io and ClickFunnels handle this automatically when someone opts in.

Step 3: Build a High-Converting Landing Page

Your landing page has one job: get visitors to hand over their email address in exchange for your lead magnet. Therefore, everything on the page should serve that single goal.

Elements of a high-converting landing page:

• A clear, benefit-driven headline. Tell them exactly what they’ll get and why it matters. For example: “Download the Free Sales Funnel Blueprint That Generated £50K in 90 Days.”
• Supporting subheadline. Then expand on the promise or address an objection.
• Bullet points of benefits. Not features — outcomes. What will they be able to do after consuming your lead magnet?
• A visual of the lead magnet. Include a mockup of your PDF, video thumbnail, or template preview.
• A simple opt-in form. Name and email are enough. Every extra field reduces conversions.
• Social proof (optional but powerful). For instance, testimonials, download counts, or trust badges.
• No navigation menu. Remove distractions — in particular, avoid any links that lead away from the page.

Tools for building landing pages:

Systeme.io	Beginners & budget-conscious	Free (up to 2,000 contacts)

Step 4: Set Up an Email Nurture Sequence

Once someone opts in, your email sequence does the heavy lifting of building trust, demonstrating value, and moving them toward a purchase. In fact, this is where most of your conversions actually happen.

A proven 5-email welcome sequence:

1. Email 1 (immediately): Deliver the lead magnet. Send the download link, set expectations for what’s coming next, and remind them of the key benefit.
2. Email 2 (Day 1): Share your story. Why do you do what you do? Build a human connection and establish credibility.
3. Email 3 (Day 3): Provide additional value. Share a tip, case study, or resource related to their pain point. No selling yet.
4. Email 4 (Day 5): Introduce the solution. Now bridge from the problem to your paid offer. Frame it as the natural next step.
5. Email 5 (Day 7): Make the offer with urgency. Present your product or service with a clear CTA, deadline, or limited bonus.

Key principles:

• Write conversationally — as though you’re emailing one person, not a list
• Most importantly, every email should deliver value, even the sales emails
• Also use storytelling to make your points stick
• Keep subject lines short, specific, and curiosity-driven
• Finally, always include one clear call-to-action per email

Email marketing tools:

• GetResponse — Excellent automation features with landing page builder included
• ConvertKit — Popular with creators, intuitive visual automations
• Systeme.io — Built-in email marketing on the free plan (a great option if you want everything in one place)
• Kartra — Advanced behavioural triggers and lead scoring

Step 5: Create a Sales Page That Converts

Your sales page is where the transaction happens. As a result, it needs to overcome objections, build desire, and make the purchase feel like a no-brainer.

Essential sales page structure:

1. Headline: Address the biggest desire or pain point
2. Problem agitation: Describe their current situation and frustrations vividly
3. Solution introduction: Present your product as the answer
4. Features and benefits: List what’s included, but always tie features back to outcomes
5. Social proof: Testimonials, case studies, results, logos, or review scores
6. Pricing: Present clearly with anchoring (compare to alternatives or the cost of not solving the problem)
7. Guarantee: Remove risk with a money-back guarantee
8. FAQ section: Handle remaining objections
9. Final CTA: Restate the key benefit and make it easy to buy

Short-form vs long-form: Low-priced products (under £50) usually work well with shorter pages. However, high-ticket offers (£500+) typically need long-form sales pages that thoroughly address every objection.

Tools: ClickFunnels and Kartra offer dedicated sales page templates with built-in checkout. Leadpages works well for simpler sales pages with external payment processors.

Step 6: Add Upsells and Downsells

Interestingly, the real profit in a funnel often comes after the initial purchase. Upsells and downsells therefore increase your average order value without requiring more traffic.

What are they?

• Upsell: A higher-value or complementary offer presented immediately after purchase. For example: “You just bought our Sales Funnel Template Pack — want to add the Video Walkthrough Training for 50% off?”
• Downsell: Alternatively, a lower-priced option offered when someone declines the upsell. For instance: “Not ready for the full training? Get the Quick-Start Cheat Sheet for just £17.”
• Order bump: Similarly, a small add-on offered on the checkout page itself, like an extended licence or bonus resource.

Best practices:

• First, keep upsells relevant to the original purchase
• Limit to 1-2 upsell offers — because too many feels pushy
• Furthermore, use one-click upsells (no re-entering payment details) for maximum conversion
• Price upsells at 30-60% of the main offer
• Above all, always offer a “no thanks” option — never force the upsell

Tools: ClickFunnels, Kartra, and Systeme.io all support one-click upsell and downsell pages natively. This is a key feature to look for when choosing your funnel builder — see our best sales funnel builders comparison for a full breakdown.

Step 7: Test, Measure, and Optimise

Your funnel won’t be perfect on day one — and that’s fine. Nevertheless, the businesses that win are the ones that consistently test and improve.

Key metrics to track:

Metric	What It Tells You	Good Benchmark
Landing page conversion rate	% of visitors who opt in	20-40%
Email open rate	Subject line effectiveness	30-50%
Email click-through rate	Content relevance & CTA strength	3-7%
Sales page conversion rate	Offer & copy effectiveness	1-5%
Upsell take rate	Upsell relevance & pricing	10-25%
Cost per acquisition (CPA)	Profitability of traffic source	Varies by niche

What to A/B test first (in priority order):

1. Headlines — The single biggest lever on any page
2. Call-to-action copy and button colour — Small changes, outsized impact
3. Lead magnet offer — If opt-in rates are below 20%, test a different lead magnet entirely
4. Email subject lines — Test length, personalisation, and curiosity hooks
5. Pricing and offer structure — Payment plans vs one-time, bundling, bonuses
6. Page layout and length — Test removing or reordering sections

Tools: Google Analytics (free) for traffic and conversion tracking. ClickFunnels and Unbounce have built-in A/B testing. Clickmagick for advanced link tracking and attribution.

7 Common Sales Funnel Mistakes (and How to Avoid Them)

1. Skipping audience research. Building a funnel without knowing your audience is like writing a letter to “whom it may concern.” So do the research first — even a few customer interviews can transform your messaging.
2. Making the lead magnet too generic. “Free ebook” isn’t compelling. Instead, be specific about the outcome: “The 5-Step Checklist to Double Your Landing Page Conversions This Week.”
3. Too many form fields. In fact, every additional field you add to your opt-in form reduces conversions by roughly 10%. Stick to name and email — you can always segment later.
4. Selling too soon. If your first email after opt-in is a hard pitch, expect high unsubscribe rates. Therefore, build trust and deliver value before asking for the sale.
5. Ignoring mobile users. Currently, over 60% of web traffic is mobile. If your landing page and emails don’t look great on a phone, you’re losing the majority of your audience.
6. Never testing anything. “Set it and forget it” is a myth. On the contrary, the highest-performing funnels are constantly being tested and refined. Start with headline tests — since they have the biggest impact.
7. No follow-up for non-buyers. Someone who didn’t buy today might still buy next month. Consequently, set up a long-term nurture sequence for leads who don’t convert immediately.

Frequently Asked Questions

How much does it cost to build a sales funnel?

You can build a basic sales funnel for free using Systeme.io’s free plan, which includes landing pages, email marketing, and sales pages for up to 2,000 contacts. Alternatively, paid tools like ClickFunnels start at $97/month and offer more advanced features. Overall, most small businesses spend between £0 and £200/month on funnel tools.

How long does it take to build a sales funnel?

A simple lead generation funnel (landing page + email sequence) can be built in a weekend. However, a more complex funnel with sales pages, upsells, and automation typically takes 1-2 weeks. Either way, the key is launching quickly with a minimum viable funnel and improving over time.

Do I need a website to build a sales funnel?

No. Most funnel builders like ClickFunnels, Systeme.io, and Kartra host your pages on their platform. You can connect a custom domain later, but it’s not required to get started.

What is the best sales funnel builder for beginners?

Systeme.io is our top pick for beginners because it’s free to start, includes all essential features (funnels, email, courses), and has a gentler learning curve. For those with more budget, ClickFunnels offers more templates and advanced features. See our full comparison of the best funnel builders.

How do I drive traffic to my sales funnel?

The most common traffic sources are: SEO content (blog posts targeting buyer-intent keywords), social media (organic posts and stories), paid ads (Facebook, Google, TikTok), YouTube (tutorials and reviews), and partnerships (guest posts, podcast appearances, joint ventures). Start with one channel, master it, then expand.

What conversion rate should I expect from my funnel?

Typical benchmarks: landing page opt-in rates of 20-40%, email open rates of 30-50%, and sales page conversion rates of 1-5%. These vary widely by industry, offer price, and traffic quality. Don’t compare yourself to “gurus” claiming 80% conversion rates — focus on improving your own numbers over time.

Can I build a sales funnel without email marketing?

Technically yes, but we strongly advise against it. Because email is where most funnel revenue is generated, removing it means you’re relying on a single touchpoint to convert cold traffic into buyers — which rarely works for anything beyond impulse purchases under £20.

What’s the difference between a sales funnel and a marketing funnel?

They’re often used interchangeably. Strictly speaking, a marketing funnel covers the full journey from awareness to consideration, whereas a sales funnel focuses on the conversion stages (decision and purchase). In practice, however, most online businesses build one integrated funnel that covers both.
