What Is A/B testing?

A/B Testing

A/B testing, or split testing, is a method used to compare two versions of a web page or app to see which one performs better. Essentially, it’s an experiment where users are randomly shown different versions of a page, and statistical tools determine which version better achieves a specific conversion goal.

Conducting an A/B test allows for focused inquiries into website or app changes, gathering data on their effects. This approach removes speculation from website optimization, facilitating decisions based on data, thereby transitioning business dialogue from speculative to evidence-based. By evaluating the effect of alterations on key metrics, you can make sure each adjustment leads to beneficial outcomes.

Why A/B Testing Is Beneficial

A/B testing enables making incremental changes to user experiences while evaluating the effects on user behavior. It helps in forming hypotheses and understanding which modifications positively influence user interactions. Conversely, it can also disprove preconceived notions about the best user experience strategies.

A/B testing goes beyond resolving single issues or debates; it's a continuous process aimed at enhancing user experiences or achieving specific goals such as conversion rate optimization (CRO) over time.

For example, a B2B technology firm may use A/B testing to enhance the quality and quantity of sales leads from campaign landing pages by altering elements like headlines, form fields, and layout to increase engagement and conversion rates.

By isolating and testing individual changes, companies can identify the specific adjustments that impact visitor behavior. Over time, integrating successful changes can significantly enhance the user experience compared to the original.

A/B testing extends beyond web pages—it's also valuable in marketing and product development. Marketers can determine which ad copy garners more clicks, while product teams can assess how new features or changes affect user engagement.
