In plain terms: a sales funnel has five core stages, awareness, interest, consideration, intent, and purchase, followed by a sixth stage almost nobody talks about, which is what happens after someone buys. Most businesses lose more revenue in the gap between “interested” and “ready to pay” than they ever lose on the top end, and that’s the bit worth fixing first.
The stages, in order, without the jargon
I’ve built funnels for training companies, e-commerce brands, and solo consultants who thought a funnel was something only tech companies needed. It isn’t. Every business that has ever made a sale has run one, whether they drew it out or not. Here are the stages as I use them with clients:
- Awareness: someone finds out you exist
- Interest: they look closer and decide you’re worth their attention
- Consideration: they compare you against alternatives, including doing nothing
- Intent: they show a buying signal, a demo request, a call booking, an add to basket
- Purchase: money changes hands
- Retention and advocacy: they come back, or they tell someone else to buy from you
You’ll see this called AIDA in older marketing books, awareness, interest, desire, action. Some agencies stretch it to seven or eight stages to justify a bigger invoice. The number of boxes on the diagram matters far less than understanding what your buyer is doing at each point, which I go into in more detail in this explanation of what sales funnels are and how they work in marketing.
Stage 1: Awareness
This is the top of the funnel, where the widest part of the diagram lives and where most of the marketing budget goes. It’s a LinkedIn post, a Google ad, a podcast mention, someone finding your website through a search. At this stage, the person has a problem, or a want, but they don’t necessarily know you exist, and they definitely don’t trust you yet.
The mistake I see constantly here is businesses trying to sell at this stage. You wouldn’t propose marriage on a first date. Awareness content should answer a question or solve a small problem, not push a discovery call. A client of mine, a bookkeeping firm in Kent with three staff, used to run ads that said “Book a free consultation” straight to cold traffic. Cost per click was fine, around 90 pence, but almost nobody clicked through to book. We swapped the ad to a free downloadable checklist on year-end tax deadlines instead. Same budget, same audience, but the click-through rate on the ad nearly doubled and we started building a list instead of shouting into the void.
Stage 2: Interest
Now the person knows you exist and they’re curious enough to give you a bit more of their time or their details. This is where email signups happen, where someone follows your business page, where they read a second blog post instead of bouncing after the first. They’re not ready to buy. They’re deciding whether you’re worth continuing to pay attention to.
This stage lives and dies on trust signals. Case studies, client numbers, before-and-afters, a face on the About page instead of a stock photo. I’ve watched businesses skip straight from a cold ad to a sales page and wonder why nobody converts. There’s a whole missing stage in between where people just want to see that you’re real and that you know what you’re talking about.
Stage 3: Consideration
This is the stage where your prospect is comparing. Not always comparing you to a direct competitor either, often they’re comparing your solution to doing nothing at all, or to solving the problem themselves badly and slowly. This is the stage most funnels are weakest at, because it requires patience and most businesses want a sale within a week of first contact.
Email nurture sequences live here. Retargeting ads live here. Webinars live here. If you sell anything over a few hundred pounds, expect this stage to take weeks, sometimes months. B2B software deals over £5,000 a year commonly take three to six months from first contact to signed contract, according to data widely cited by sales research firms like Gartner. If your funnel assumes everyone decides in 48 hours, you’ve built it for the wrong kind of purchase.
Stage 4: Intent
This is the stage where someone shows you, with an action rather than a click, that they’re close to buying. They book the call. They add the item to their basket. They ask about pricing directly. They request a proposal. This is the most valuable stage in the entire funnel because these people have already self-selected as serious, and it’s also the stage most badly mishandled.
Here’s a specific number worth knowing: a study of B2B lead response times by the Harvard Business Review found that companies which contacted a lead within an hour of a form submission were nearly seven times more likely to qualify that lead than companies who waited even 24 hours. I’ve seen this play out with a client, a small events company, whose demo request form sat unread for two to three days at a time during busy weeks. We put a simple auto-response and a same-day call-back rule in place. Nothing clever, just speed. Their close rate on demo requests went from around 15% to 34% within two months, with no change to the offer itself.
Stage 5: Purchase
The stage everyone talks about, the actual transaction. Card details entered, contract signed, invoice paid. It looks like the finish line, and in most funnel diagrams it’s drawn as the bottom point, but treating it as the end is where a lot of businesses quietly bleed money. If you want a full worked example of how these five stages play out with real traffic and real conversion percentages from top to bottom, I’ve broken one down step by step in this walkthrough of what a typical sales funnel looks like.
Stage 6: Retention and advocacy
Here’s the uncomfortable bit that most funnel articles leave out entirely, probably because it’s less exciting to write about than ad targeting. The purchase is not the end of the funnel, it’s the middle. What happens after someone pays you determines whether your entire funnel becomes profitable or stays a cost centre forever.
It costs roughly five times more to acquire a new customer than to keep an existing one, a figure that’s been repeated by Harvard Business Review and marketing researchers for years because it keeps proving true across industries. Yet I still walk into businesses where the onboarding email is an afterthought, there’s no follow-up at day 30, and nobody has ever asked a happy customer for a referral or a review. That’s not a marketing failure, it’s a funnel design failure. If retention and referral aren’t built in as a formal stage with its own emails, its own check-in calls, its own review requests, you’re rebuilding your entire funnel from stage one every single month instead of letting stage six do half the work for you.
A real funnel, with real numbers, front to back
To make this concrete, here’s an anonymised version of a funnel I set up for a small training business selling an £800 online course. Over one quarter:
- Awareness: 14,000 people saw the ad or organic content
- Interest: 620 clicked through to a free guide landing page (roughly 4.4%)
- Consideration: 340 downloaded the guide and entered a five-email nurture sequence (about 55% of clickers)
- Intent: 58 booked a discovery call from the nurture sequence (17% of the 340)
- Purchase: 21 became paying customers (36% of the calls)
Nine months earlier, before we restructured the funnel around these six distinct stages, that same ad spend produced roughly the same amount of traffic but only 6 customers a quarter, because there was no interest stage at all, people went straight from ad to a hard sales page, and no consideration stage, because there was no nurture sequence to build trust before the call. Same budget, more than triple the customers, purely from respecting that people move through stages at their own pace rather than the pace the business wants.
Where the diagram lies to you
Funnel diagrams are drawn as neat, one-directional triangles, and that’s the part I’d push back on. Real buyers move sideways and backwards constantly. Someone reads your case study (consideration), goes quiet for six weeks, comes back through a Google search (looks like awareness again), rereads your pricing page (intent), and then books a call after seeing a testimonial pop up on your site (back to consideration). The funnel isn’t a straight pipe, it’s closer to a maze that most people wander in and out of before they buy, and different types of sales funnels handle that wandering differently depending on whether you sell a £30 product or a £30,000 contract.
This matters practically because it means your job isn’t to force people down a straight line. It’s to have the right content and the right offer ready at whichever stage they show up at, however many times they loop back through.
How to map these stages onto your own business this week
You don’t need software or a consultant to start. You need a piece of paper and an honest look at your own data.
- Write down every place a stranger currently finds out you exist (that’s your awareness stage, list them all, even the ones you’re embarrassed about)
- Look at what happens immediately after someone clicks through, is there anything asking for their name and email, or do they land straight on a sales pitch
- Check how long it takes someone from “interested” to being contacted by a human, if it’s more than a few hours you’re losing intent-stage leads right now
- Look at what happens in the 30 days after someone pays, is there a plan, or does it just stop
If that audit feels overwhelming or you can’t tell where your own leaks are, that’s exactly the sort of thing sales funnel management is meant to solve, it’s the ongoing discipline of watching these numbers between stages rather than building a funnel once and hoping.
And if you’re still not convinced a formal funnel is worth the effort for a small business, it’s worth reading through what happens to revenue and customer consistency when there isn’t one, which I’ve laid out plainly in why a sales funnel matters and what happens without one.
The stage nobody wants to admit is the problem
If I’m blunt, and I usually am, most businesses don’t have an awareness problem. They have plenty of traffic, plenty of followers, plenty of people who’ve heard of them. What they don’t have is a consideration stage or an intent stage worth the name, no nurture sequence, no speedy follow-up, nothing built for the person who’s interested but not ready today. So they keep pouring more budget into the top of the funnel, chasing more strangers, when the leak has been in the middle the whole time. It’s a far less glamorous fix than a flashy ad campaign, and that’s exactly why it gets ignored.
Frequently asked questions
How many stages does a sales funnel have?
Most models use five to six stages: awareness, interest, consideration, intent, purchase, and retention. Some agencies split these further into seven or eight labels, but the underlying buyer behaviour, discovering you, trusting you, comparing you, showing intent, paying, and staying, doesn’t change with the number of boxes.
What is the most important stage of a sales funnel?
Intent, the moment someone shows a genuine buying signal like booking a call or requesting pricing, is the stage most businesses mishandle worst, and it’s also the one with the highest use, since studies on lead response times show contacting a lead within an hour can make it seven times more likely to convert compared with a next-day response.
Do all sales funnels follow the same order?
No. Real buyers loop back and forth between stages, rereading pricing pages, revisiting testimonials, or Googling you again weeks after first contact, so the neat one-way diagram is a teaching tool rather than an exact map of how people behave.
Does the sales funnel end when someone buys?
No, and treating purchase as the final stage is one of the most common and costly mistakes in funnel design. Retaining and referring customers costs roughly a fifth of what it costs to win a new one, so a funnel without a formal retention and advocacy stage forces a business to rebuild demand from scratch every single month.
