Split Testing
Split testing, also called A/B testing, compares two or more versions of a page or element by showing each to a separate slice of traffic to see which performs best.
Split testing vs A/B testing
The terms are used interchangeably. Split testing emphasizes that traffic is split between variants, while A/B testing emphasizes comparing version A to version B. Both describe the same controlled comparison.
How it works
You define a goal, such as sign-ups, create a variant, and split visitors randomly so each version reaches a comparable audience. Once enough data accumulates to reach statistical significance, the better-performing version wins.
Split URL vs on-page tests
A split URL test sends traffic to two different page URLs, while an on-page test swaps elements within the same URL. Choose split URL for large redesigns and on-page tests for targeted element changes.
