Stop guessing. Learn how to run tests that produce reliable results and what to test first.

In this lesson you’ll learn to

  • I write hypotheses before testing
  • I test one main change at a time
  • I wait for enough conversions
  • I check lead quality, not just volume
  • I log every test

The process

• Find the problem (analytics, recordings, surveys).

• Write a hypothesis: “If we change X, Y will improve because Z.”

• Create one variation.

• Split traffic evenly and run until you have enough conversions.

• Implement the winner and record the learning.

What to test first

• Headline and offer.

• Form length and steps.

• CTA wording and placement.

• Proof and trust signals.

• Call vs form.

Avoid mistakes

• Stopping tests too early.

• Testing tiny changes on low traffic.

• Changing several things at once without knowing why it won.

• Ignoring lead quality — a variant with more but worse leads is not a winner.

Low traffic?

Test bigger changes, use qualitative research (recordings, interviews), and focus on best practices first.
