01 · A/B testing

What to test first

Start where the most visitors are: the headline of your sales page. Then the offer on your upsell. Small copy changes on high-traffic steps pay off fastest.

  • Headline and hero image
  • Price and bundle framing
  • Upsell offer and discount

02 · A/B testing

Fair tests, clear results

A visitor is assigned a version once and keeps it, so returning visitors don't skew the numbers. Conversions and revenue are counted per variant.

  • Sticky assignment per visitor
  • Conversion rate per variant
  • Promote the winner in one click
