Sales funnel: find the step where your website loses customers
Visitors arrive, few get in touch. A sales funnel shows you the exact step where they drop off. Here is how to measure it and what to fix first.

Your website gets visits, your analytics say so. But quote requests barely trickle in. Somewhere between a visitor landing and a form being sent, something leaks. A sales funnel, or conversion funnel, is simply a way of cutting that path into steps so you can see where.
The funnel, without the jargon
The most common model splits a customer's path into four moments: they discover your business, get interested, compare and decide, then act. Authors use different names (you will also see the AIDA acronym), but the idea is the same: at every step, some people stop. That is normal. The job is to spot the step where you lose more people than you should.
On a service business website, the funnel usually comes down to four very concrete steps:
- the visitor lands on a page (home, service, article);
- they read your offer, often including your prices;
- they start filling in the form;
- they send it.
If you remember one thing: each step has to be measured on its own. Otherwise you know you are losing customers, but not where.
Measure every step
Two common tools can do this without heavy development.
In Google Analytics 4, the funnel exploration shows how many people reach each step and the drop-off rate between steps. Google offers two modes: an open funnel, where people can enter at any step, and a closed funnel, where they must start at the first one.
Umami, the cookie-free analytics tool we use, also has a funnel report. You define steps (a page address or an event) in a fixed order, and it counts how many visitors get through each one.
Either way, steps 3 and 4 require two events on your form: "form started" and "form sent". It is a small change, but without it you will never see what happens inside the form itself.
The three most common leaks
When we look at these numbers on small-business sites, the same leaks keep showing up.
The form is too long. Nielsen Norman Group, a web usability research firm, recommends removing any field whose information can be collected later or obtained another way. It cites its own case: a form cut from six fields to two. Before asking for budget, headcount and timeline, ask yourself what you truly need to call the person back.
The next step is unclear. A convinced visitor who cannot find the button leaves. One main call to action per page, with a label that says what will happen, beats three buttons competing for attention.
The page is too slow. A visitor who is waiting is not reading your offer. We explained how to check your site's speed yourself in an earlier article.
Split the form instead of making it longer
On our own site, we chose a two-step form: email first, then the rest. The first step takes almost no effort, and the person has already moved forward when the next questions appear. Nielsen Norman Group also suggests showing only what the current task needs, even if that means spreading a form across several screens.
Splitting has another benefit: it adds a step to your funnel. You can see how many people give their email and then quit, which tells you exactly what to adjust in step two.
Where to start this week
Open your analytics tool and write down three numbers for the last 30 days: visitors, people who viewed your contact or pricing page, and forms sent. If you cannot get the second or third number, that is your first job: add the missing events.
Once you have the numbers, tackle the step with the biggest gap. One at a time, so you know what worked.
