Introduction to A-B Testing

A-B testing, also known as split testing, is a method used to compare two versions of a webpage or app against each other to determine which one performs better. This technique is crucial for making data-driven decisions that can enhance user experience and improve key performance indicators (KPIs).

What is A-B Testing?

A-B testing involves splitting your audience into two groups: Group A and Group B. Group A sees the original version (control) while Group B sees the modified version (variation). By analyzing the performance of these two groups, you can determine which version is more effective in achieving your goals.

Importance of A-B Testing

A-B testing is essential for optimizing user experience and increasing conversion rates. It allows businesses to make informed decisions based on actual user data rather than assumptions. This method helps in identifying what works best for your audience, thereby reducing risks associated with changes.
