The Marketing Funnel Explained, With a Worked Example
Updated · By Robert Breen
The problem
Dana runs marketing for a 12-person bookkeeping firm. The website got 4,000 visits last month, up 30%, yet new clients stayed flat at 6. Her boss asks whether to spend more on ads. Dana cannot say, because she does not know where the visitors are dropping off.
What you’ll be able to do
By the end you will be able to sketch any business’s funnel on one page, put a number on each stage, find the stage that loses the most people, and know which fix belongs to which stage before you spend another dollar.
The funnel in one sentence
A marketing funnel is the path from "has never heard of you" to "paying customer", split into stages so you can count how many people reach each one. It is drawn as a funnel because every stage has fewer people than the one before.
Most teams use three stages. Awareness: people see you (an ad, a search result, a post). Consideration: they visit, read and compare. Conversion: they take the step that matters, such as booking a call or buying.
Dana’s funnel, with numbers
| Stage | What counts | Last month | Rate to next stage |
|---|---|---|---|
| Awareness | Search and ad impressions | 96,000 | 4.2% click through |
| Visit | Website sessions | 4,000 | 1.5% book a consultation |
| Lead | Consultation booked | 60 | 10% sign |
| Customer | Signed engagement | 6 | n/a |
Read it top to bottom. 96,000 impressions became 4,000 visits, which became 60 consultations, which became 6 clients. Each rate is the next number divided by the current one: 4,000 / 96,000 = 4.2%, 60 / 4,000 = 1.5%, 6 / 60 = 10%.
Find the leak before you spend
The question is not "which number is small?" (the bottom of every funnel is small). It is "which rate is worse than it should be?". For a professional-services site, booking rates of 2% to 5% of visits are common. Dana’s 1.5% is the weak stage. Her click-through rate is fine and her close rate of 10% is in line with similar firms.
So more ad spend would mostly buy more visitors who do not book. The cheaper fix is in consideration: a clearer booking page, a price range on the site, testimonials near the booking button. Lifting the booking rate from 1.5% to 3% would double clients to 12 with the same 4,000 visits.
Which channel and metric belong to each stage
| Stage | Typical channels | Metric to watch |
|---|---|---|
| Awareness | Paid social, display ads, SEO for broad topics | Impressions, reach, cost per thousand impressions |
| Consideration | Search ads, blog posts, comparison pages, email | Click-through rate, bounce rate, pages per session |
| Conversion | Landing pages, retargeting, sales calls | Conversion rate, cost per acquisition |
Common funnel mistakes
Judging a channel by the wrong stage. A brand-awareness campaign will never show many direct sales; judge it on reach and cost per impression. A retargeting campaign should be judged on conversions.
Counting different things at each stage. If "visits" is sessions but "leads" includes phone calls that never touched the site, the rates mean nothing. Write down exactly what counts at each stage.
Ignoring time lag. A business client may click in March and sign in May. Compare rates over a window long enough for most people to get through.
Check your understanding
Dana’s site gets 4,000 visits and 60 consultations. What is the booking rate?
Show the answer
1.5%. 60 / 4,000 = 0.015, which is 1.5%.
Which stage should Dana fix first?
Show the answer
Consideration: get more visitors to book. Her booking rate (1.5%) is below what similar sites see, while click-through and close rates are normal. Fixing the weakest rate gives the biggest gain for the least money.
A brand-awareness video campaign shows almost no direct sales. What should you judge it on?
Show the answer
Reach and cost per thousand impressions. Awareness campaigns work at the top of the funnel. Judge them on how many of the right people they reach and at what cost.
