A/B Testing / Split Testing
Splitting traffic 50/50 between original control (A) and variant (B) differing by one variable
In Simple Words (Zero Jargon):
Showing Version A (original page) to 50% of visitors and Version B (with a new headline or button) to the other 50% to see which makes more sales.
Why It Is Critical
Test only one variable at a time in standard A/B tests so you know exactly which element drove the lift. Always run tests for full 7, 14, or 21-day cycles to capture weekday vs weekend consumer variations.
'A test that feels like it is winning after two days is not a result - it is random noise that happens to be pointing in a direction you wanted to see. Never declare a winner without full weekly cycles and statistical significance.'
What You Get: Proof that a website change genuinely increased revenue rather than a coincidence mistaken for a win.
