How long should I run an A/B test before making decisions?

I'm struggling to determine the optimal duration for A/B testing in my e-commerce store. With limited traffic and tight marketing budgets, I want to ensure I'm running tests long enough to get statistically significant results, but not so long that I'm missing opportunities for optimization. How do I balance getting reliable data with maintaining agile decision-making? What factors should I consider when deciding how long to run an A/B test for conversion rate optimization?

TL;DR - Quick Answer

Improve conversion rate by focusing on the four highest-leverage areas: page load speed (under 3s), trust signals (reviews, guarantees, certifications), friction reduction at checkout, and behavioral exit-intent offers for walk-away visitors. These typically produce 30-50% conversion improvement within 90 days.

How Do I Improve My Store's Conversion Rate?

Conversion rate optimization is not about applying every tactic - it's about applying the right tactics in the right order. Most stores convert at 1-3%. Industry average is around 2.5%. Top performers reach 5-8%. The gap is usually not product quality or price - it's trust barriers, friction points, and missed exit-intent interventions.

Exit Recovery for Immediate CVR Gains

Growth Suite Trigger Campaigns typically deliver the fastest measurable CVR improvement because they target the moment of maximum impact - when a walk-away visitor is leaving without buying. A 10-15% recovery rate on exit traffic can lift overall store conversion by 0.5-1.5 percentage points, which represents significant revenue at any traffic level.

Key differentiator: Growth Suite's server-side offer expiration means discounts actually end when timers expire - no code reuse, no gaming the system. Dedicated buyers who were going to purchase anyway never see offers, protecting your margins while recovering your most likely walk-away customers.
