A/B Testing Best Practices

Overview

A/B testing lets you compare two or more versions of your landing page to find what converts best. GetLaunchDay's built-in A/B testing makes this effortless.

Setting up an A/B test

Open your project and go to **A/B Tests → New Test**

Select what to test:

- **Headline** — Enter 2-5 headline variations

- **Full page** — Create 2-3 page variants

- **CTA** — Test different button text or color

- **Pricing** — Test different price points

Set **traffic split** (default: 50/50)

Click **Start Test**

GetLaunchDay automatically splits traffic and tracks conversions per variant.

When to stop a test

**Minimum 200 visitors per variant** — Don't pick a winner too early

**95% confidence** — The green badge means the result is statistically valid

**At least 7 days** — Avoid day-of-week bias

Common tests to run

Headlines

Test benefit-first vs. feature-first vs. question-based headlines:

"Save 3 hours every week on meal planning" (benefit)

"AI-Powered Meal Planner for Busy Families" (feature)

"Tired of deciding what to cook every night?" (question)

CTAs

"Join the waitlist" vs. "Get early access" vs. "Reserve my spot"

Orange button vs. blue button

Social proof

With testimonials vs. without

"10,000 founders trust us" vs. "Featured in TechCrunch"

Pricing

$29/mo vs. $39/mo (test willingness-to-pay using fake-door)

Mistakes to avoid

**Testing too many things at once** — Change one variable per test

**Stopping too early** — Wait for statistical significance

**Ignoring segmentation** — Mobile and desktop users may behave differently

**Not documenting results** — Keep a testing log for institutional knowledge
