Key takeaways

  • Most funnel problems are clarity, relevance or follow-up problems.
  • Fix the step with the biggest drop-off first.
  • Missing follow-up is one of the costliest and easiest mistakes to fix.

Strategy mistakes

  1. No single goal - fix: choose one conversion per funnel.
  2. Selling too early to cold traffic - fix: add a lead magnet or educational step.
  3. Lead magnet unrelated to the offer - fix: design it around the problem your product solves.
  4. Building before mapping - fix: draw the funnel on one page first.

Page mistakes

  1. Headline doesn't match the ad or link - fix: echo the promise that brought them.
  2. Too many calls to action - fix: one primary action per page.
  3. Forms too long for the value offered - fix: remove fields you don't use.
  4. Not tested on mobile - fix: complete every step on a phone before launch.

Follow-up and measurement mistakes

  1. No follow-up sequence - fix: at least a short welcome or quote follow-up.
  2. Slow response to enquiries - fix: instant acknowledgement and fast personal contact.
  3. No tracking per step - fix: set up conversion events and UTMs.
  4. Changing many things at once - fix: one change, measure, repeat.
