A/B Testing Guide

A method of comparing two versions of a webpage or app against each other to determine which one performs better.

The Concept

A/B testing (also known as split testing) involves showing two variants of the same web page to different segments of website visitors at the same time and comparing which variant drives more conversions.

Control (A)

Sign Up

Current Version

VS

Variant (B)

Get Started

New Version

The Process

  1. Analyze Data

    Use analytics to identify pages with high drop-off rates or low conversion. Find the problem areas.

  2. Formulate Hypothesis

    Make a prediction. "If we change the CTA color to blue, more users will click it because it stands out more."

  3. Create Variations

    Design the 'B' version. Keep changes focused. If you change too many things at once, you won't know what caused the difference.

  4. Run the Test

    Split your traffic randomly. Ensure statistical significance by running it long enough to get a reliable sample size.

  5. Analyze Results

    Did the variation outperform the control? If yes, implement it. If no, learn from it and iterate.
