Funnel leak calculator
See which step of your funnel is losing the most people.
Find your leak
Example numbers are filled in. Replace them with last month's.
How to read your result
Every funnel gets narrower as it goes. Clicks turn into fewer enquiries, enquiries into fewer calls, calls into fewer sales. The calculator divides each step by the one before it and marks the lowest percentage.
That lowest percentage is where to look first. It isn't always the problem, because the first step of most funnels has the lowest rate anyway. The most useful thing you can do is run this every month and compare it with your own past numbers.
What to do with each leak
- Clicks to enquiries is low: check whether the page matches the promise in your ad, loads fast on a phone, and makes the next step obvious.
- Enquiries to calls is low: check how quickly you reply. An enquiry answered the next day is often already gone.
- Calls to customers is low: listen to your calls, and check whether the ad is bringing the right people.
Why fix one step at a time
Change three things at once and you won't know which one worked. Change one, measure it, then move to the next.
