The short version: A sales funnel is the path someone takes from noticing your business to buying from it, usually mapped in stages like awareness, interest, decision, and action. Most funnels lose over 90% of the people who enter at the top, and that’s normal, not a failure. The job of marketing isn’t to stop the drop off, it’s to make sure the people who do come out the other end are the right ones, buying at a price that makes the whole thing worth running.
What a sales funnel means, without the jargon
Picture a funnel in your kitchen, the wide top and narrow bottom kind you’d use to get oil into a small bottle. Marketing borrowed that shape decades ago because it’s a decent enough picture of what happens when you sell something. Lots of people come in contact with your business (the wide top), some of them get curious, fewer of them get serious, and a small number hand over money (the narrow bottom).
That’s it. That’s the whole concept. Everything else, the diagrams, the software dashboards, the seven-stage frameworks people sell courses on, is decoration on top of that basic idea.
A sales funnel isn’t a page. I still get asked this at least once a month by clients who’ve been told their “funnel” is broken when what they mean is their landing page isn’t converting. Those are different problems, and I’ve written a whole piece on why a landing page and a funnel aren’t the same thing because mixing them up costs people real money. A landing page is one stop on the journey. The funnel is the entire journey, from the first ad someone scrolls past to the email that gets them to buy again six months later.
The stages, and what happens at each one
Most marketers still use a version of the old AIDA model, built in 1898 by an advertising bloke called E. St. Elmo Lewis, which tells you something, this thing has outlasted the telephone becoming common in homes. It’s been renamed a hundred times but the bones haven’t changed much.
- Awareness: someone finds out you exist. A social post, a Google search, a friend’s recommendation, an ad. They don’t know you and they’re not looking for a relationship yet.
- Interest: they stick around long enough to learn something. They read a blog post, watch part of a video, follow your account. This is where most people quietly leave and never come back.
- Consideration or decision: they’re comparing you to alternatives, including doing nothing. This is where price, proof, and trust do the heavy lifting.
- Action: they buy, book a call, or sign up.
- Retention (the stage most people forget entirely): they come back, buy again, or tell someone else about you.
The stage nobody wants to talk about is retention, because it’s less glamorous than “get more leads,” but it’s where the actual profit sits. Getting a new customer typically costs five to seven times more than keeping one you already have, which is a stat that’s been floating around marketing circles for years and, in my own client work, holds up almost every time I’ve measured it.
A real funnel, with real numbers, from a webinar I ran
A few years back I ran a webinar to promote a small group coaching programme. I’ll give you the actual figures because vague percentages don’t help anyone build their own.
- 4,800 people saw the promotional post on LinkedIn and Facebook combined.
- 612 clicked through to the registration page (about 12.7%).
- 340 registered (55.5% of the clicks, a decent conversion rate for a free event page).
- 119 showed up live (35% of registrations, which is roughly the industry norm, live attendance is nearly always well under half of sign-ups).
- 14 booked a call after the webinar.
- 6 became paying clients.
Six people, out of 4,800 who saw the original post. That’s a 0.125% conversion from top to bottom. If you’d shown me only that final number without the stages, I’d have told you the campaign was a waste of time. But those six clients paid £1,800 each for the programme, which is £10,800 from a campaign that cost me maybe £200 in ad spend and a Tuesday evening. That’s the bit that gets lost when people obsess over the shape of the funnel instead of what’s happening at each stage and what it’s worth.
You can see a longer, more detailed breakdown of exactly what happens between each of these steps, with the traffic sources and drop-off points laid out, in this walkthrough of what a typical funnel looks like in practice.
How the mechanics work behind the scenes
Here’s what’s running underneath the stages, in plain steps:
- Traffic comes in from somewhere specific. Not “the internet,” an actual channel: a Google ad, an Instagram post, a guest podcast appearance, an email from a partner. Know which one, because they behave completely differently. Instagram traffic in particular can be unreliable if your bio link is broken or a story link expired, which is more common than people think and worth checking regularly (I’ve had clients lose weeks of traffic to a dead link and not notice).
- A page or piece of content captures attention and asks for something small. An email address, a follow, a download. This is the trade: you give value, they give contact information.
- A follow-up sequence builds trust automatically. Emails, retargeting ads, sometimes a text sequence. This is where most small businesses fall down, they capture the email and then send nothing, or send one badly written newsletter three months later.
- An offer gets presented at the right moment. Not immediately. The data across most of my clients’ funnels shows the sweet spot for a first offer sits somewhere between the third and seventh touchpoint, not the first.
- The sale happens, and the relationship either stops or continues. This is the fork that decides whether you’re building a business or just running one-off transactions forever.
None of this happens by magic or by hope. It happens because somebody, or some software, moves each person along automatically based on what they do. That’s the whole point of a marketing automation tool, it tags a person the moment they click, watch, or buy, and sends the next relevant thing without you sitting there manually doing it. I use ActiveCampaign for most of my own funnels, though HubSpot and Keap do similar jobs at different price points and complexity levels.
The bit most people don’t want to hear
Here’s the uncomfortable part. A funnel doesn’t fix a weak offer. I’ve built beautifully structured funnels, gorgeous emails, perfect timing, for products that nobody particularly wanted, and they still didn’t sell. The funnel just got people to say no faster and more efficiently.
I had a client in 2023 who spent nearly £4,000 on funnel software, copywriting, and ad spend for a digital course that, honestly, wasn’t different enough from a dozen free YouTube playlists covering the same ground. The funnel worked exactly as designed. Traffic came in, the sequence sent, people opened the emails at a healthy 38% rate. Almost nobody bought. The funnel wasn’t broken. The offer was.
Most people selling “funnel fixes” won’t say this because it’s more comfortable to sell you a better funnel than to tell you your product needs work first. But the order matters: get the offer right, then build the funnel around it, not the other way round.
Where sales funnel management fits into all this
Once you’ve got more than one funnel running, or your business relies on a steady flow of leads rather than occasional bursts, you need to manage the thing rather than just build it once and hope. That means watching conversion rates between each stage, spotting which one is leaking hardest, and fixing that specific stage rather than rebuilding everything from scratch every time numbers dip. I go into what that looks like day to day, including which metrics matter and which ones are vanity numbers, in this piece on sales funnel management and why every business needs it, even small ones with a handful of clients.
If you’re on the other side of this, building funnels for other people rather than your own business, there’s a decent living in it. I’ve written about the practical side of that, including pricing and how to package the service, in how to sell sales funnel design as a service, which is worth a look if you’re a freelancer or agency owner wondering whether it’s worth specialising in.
Building your first funnel without overcomplicating it
If you’re starting from nothing, here’s what I’d build, in order, rather than the twelve-stage diagrams that get thrown around on LinkedIn:
- One traffic source you already understand, not five you’re guessing at.
- One landing page with one offer and one call to action, not three competing for attention.
- A five to seven email sequence that teaches something useful before it sells anything.
- One clear offer, priced so the maths works even at a low conversion rate (do the sum on paper first, like I did with the £10,800 from six people).
- A simple way to track the numbers at each stage, even a basic spreadsheet counts, so you know which part needs attention.
That’s a working funnel. Everything after that is refinement, not reinvention.
Frequently asked questions
What’s the difference between a sales funnel and a marketing funnel?
In most conversations the two terms get used interchangeably, and honestly the distinction rarely matters in day-to-day work. If you want a technical split, a marketing funnel usually covers everything up to the point someone considers buying, and a sales funnel covers the point where a person or a piece of software actively pushes them toward payment. Most small businesses run both stages as one connected system anyway.
How many stages should a sales funnel have?
There’s no fixed number, and anyone insisting on exactly seven or nine stages is usually selling a framework. Three works fine for simple products: awareness, decision, action. Complex or expensive offers, coaching programmes, B2B software, high ticket services, tend to need more stages because people need more touchpoints before they trust a bigger price tag.
Why do most sales funnels have low conversion rates?
Because that’s how funnels are supposed to work. A top-to-bottom conversion rate of 1 to 3% is common and healthy for cold traffic. The number that matters isn’t the overall percentage, it’s whether the people who reach the bottom are paying enough, and often enough, to make the traffic and effort worth it.
Do I need software to run a sales funnel?
Not at the very start. You can run a basic version with a free landing page tool and a manual email list of a few dozen people. Once you’re sending more than a couple of hundred emails a month or trying to track behaviour across several stages, a proper marketing automation tool earns its cost quickly in saved time and better timing.
