How to read your funnel
A sales funnel is a series of steps, and each one loses some people. Revenue is simply visitors multiplied by every step's conversion rate, multiplied by the value of a sale.
Ways to lift each step
- Opt-in: one clear offer, a stronger lead magnet and fewer form fields.
- Booked call: instant follow-up by email and SMS, plus a calendar on the thank-you page.
- Sale: reminders before calls, case studies, and a simple guarantee.
FAQs
What is a good funnel conversion rate?
It varies by offer, but landing pages often convert 10 to 30% of visitors to leads, and 20 to 40% of booked calls typically close. Compare against your own history first.
Which step should I fix first?
Usually the step with the lowest conversion rate, because improvements there multiply through every step below it. The calculator highlights it for you.
Why does improving one step raise revenue by the same percentage?
Funnel steps multiply. If one step converts 20% better, everyone below it grows by 20% too, so revenue rises by the same share.
Can you build the funnel for me?
Yes. PlanB Digital designs and builds complete funnels, from landing pages and lead magnets to email follow-up and checkout.
