CRO patterns

20 evidence-based interventions, each with published CVR lift ranges, the conditions where it works, the conditions where it backfires, and explicit ethical notes (because some patterns slide into dark-pattern territory if implemented carelessly).

Lift-range honesty

Lift ranges come from published A/B-test studies — VWO, Optimizely, Baymard, Mixpanel, real practitioner case studies. Your funnel is not their funnel; treat ranges as orientation, not promises. The patterns that work everywhere are the friction-reduction ones (guest checkout, transparent pricing). The patterns that backfire most often are urgency + scarcity when implemented dishonestly — see each pattern’s ethical notes.
