A/B Testing
It is a method of comparing two versions of a webpage, app feature, or any digital experience to determine which one performs better.
What is A/B Testing?
A/B testing, also known as split testing, is a method of comparing two versions of a webpage, app feature, or any digital experience to determine which one performs better. By randomly showing users version A or version B and analyzing the results, businesses can make data-driven decisions rather than relying on guesswork or intuition. This methodology is widely used in product design, marketing, and UX to fine-tune user experiences and increase conversions.
The key to successful A/B testing lies in its simplicity: one change, one measurement. For example, you might test two different headlines on a landing page to see which gets more clicks. This controlled experimentation helps isolate the effects of specific changes.
Why use A/B Testing?
A/B testing enables startups and established businesses alike to validate ideas before making full-scale changes. Instead of overhauling a product based on internal opinions, you can run small, measured experiments to see what actually works. This reduces risk and encourages a culture of evidence-based decision-making.
The benefits of A/B testing include:
- Improved conversion rates through optimised designs and messaging
- Increased user satisfaction by tailoring experiences to real preferences
- Faster iteration cycles without large-scale overhauls
- Cost-effective learning by testing small changes with big potential impact
When to use A/B Testing?
Timing is key with A/B testing. It’s best used when you have a clear hypothesis to test and a measurable goal, such as increasing signups or reducing bounce rates. If you’re rolling out a new feature or redesign, A/B testing can validate its effectiveness before full deployment.
You should consider using A/B testing:
- When launching a new product page
- To test different pricing models
- To optimise email subject lines or call-to-action buttons
- Before investing in a full-scale redesign
It’s important to note that A/B testing requires a sufficient sample size to be statistically significant. As HubSpot highlights, small traffic volumes can lead to inconclusive results or misleading insights, so ensure you’re testing in the right context.

ou should run an A/B test until it reaches statistical significance, which depends on your sample size and the effect you're trying to measure. Typically, this means at least one to two weeks to account for day-of-week variations.
Our system can support you
Inconclusive results aren’t a failure. They're a signal that your hypothesis may need refining. You might need a larger sample size, a more impactful change, or to look at different metrics. Use what you’ve learned to iterate and run a better-informed test next time.
