Online Sales Funnel - How It Works and How to Build One
Online Sales Funnel - How It Works and How to Build One
TL;DR
A sales funnel has 3 stages: TOFU (awareness - blog, video, social), MOFU (consideration - retargeting, email, case studies), and BOFU (decision - landing page, direct offer). Ideal budget split: 60-70% TOFU, 20-25% MOFU, 10-15% BOFU. Without a funnel, you're selling cold with high costs.
An online sales funnel is the path a potential customer takes from "I don't know you" to "I'm buying from you." Most businesses make one mistake: they jump straight to the sale without the intermediate stages. The result: high customer acquisition costs and low conversion rates.
What's a Funnel and Why Does It Matter
Picture a funnel. Many people enter at the top (visitors). Few come out at the bottom (customers). Between the two are stages people pass through gradually: they learn about you, get interested, evaluate, and finally buy.
Without a funnel: you run "Buy Now!" ads to cold people who don't know you. Conversion rate is under 1%, cost per customer is high.
With a funnel: you bring people through stages, give value at each step, and when they reach your sales offer, they're ready. Conversion rate is 5-15%, cost per customer drops.
The 3 Funnel Stages
TOFU (Top of Funnel) - Awareness
Goal: People learn you exist and that you have something relevant for them.
Content: Blog posts, educational videos, social media posts, infographics, podcast episodes. Content that solves a problem or answers a question without selling anything directly.
Channels: Facebook/Instagram Ads with awareness or traffic objective, SEO/blog, YouTube, TikTok, Google Display Ads.
Metrics: Reach, impressions, site visits, video views, engagement.
Budget: 60-70% of total marketing budget.
MOFU (Middle of Funnel) - Consideration
Goal: People who already know you evaluate whether you're the right solution.
Content: Case studies, comparisons, webinars, detailed guides, email sequences, video testimonials, demos. Content that demonstrates your expertise and results.
Channels: Email marketing (nurture sequences), Facebook/Google retargeting (on site visitors), YouTube remarketing.
Metrics: Email open rates, click-through rates, time on site, pages per session, lead magnet downloads.
Budget: 20-25% of total marketing budget.
BOFU (Bottom of Funnel) - Decision
Goal: Convert the interested person into a paying customer.
Content: Specific offer, free consultation, discount, trial, live demo. Content that removes the last objection and makes saying "yes" easy.
Channels: Retargeting hot audiences (visited pricing page, started checkout, opened proposal), email final sequence, direct sales call.
Metrics: Conversion rate, cost per acquisition, ROAS, close rate.
Budget: 10-15% of total marketing budget.
The Biggest Mistake: Selling to Cold Audiences
Running a "Book a Consultation" ad to people who've never heard of you is BOFU content served to a TOFU audience. It can work, but it's expensive. You're asking someone to commit before they trust you.
The funnel approach: first show them a useful blog post (TOFU), then retarget with a case study (MOFU), then retarget again with a consultation offer (BOFU). By the time they see the offer, they've already seen your expertise twice.
Practical Funnel Examples
Dental Clinic:
- TOFU: Blog post "5 Signs You Need a Dental Checkup" + Facebook ad driving traffic
- MOFU: Retarget blog readers with a video testimonial from a patient
- BOFU: Retarget video viewers with "Free Initial Consultation - Book This Week"
Marketing Agency:
- TOFU: Educational video "3 Google Ads Mistakes Wasting Your Budget"
- MOFU: Retarget with a case study showing 200% ROI for a similar business
- BOFU: Retarget with "Free Campaign Audit - See Where You're Losing Money"
E-commerce:
- TOFU: Instagram Reels showing the product in use
- MOFU: Retarget with user reviews and comparison content
- BOFU: Retarget with discount code + free shipping offer
How to Build Your First Funnel (Minimum Viable Funnel)
- Create one piece of valuable content - a blog post or video that solves a real problem
- Run a traffic ad to a relevant audience driving them to that content
- Set up retargeting on everyone who consumed the content (visited the page, watched 50%+ of the video)
- Create a conversion offer and show it only to the retargeting audience
- Set up email capture somewhere in the process (lead magnet, newsletter, consultation request)
- Build a 3-5 email nurture sequence for captured leads
Total cost: your content creation time + $300-500/month ad spend. That's a working funnel.
