A/B testing: Optimise your conversions and user experience
A/B testing, also known as split testing, is a powerful method for optimising websites, apps, and marketing campaigns. It involves comparing two versions (A and B) of a webpage, app feature, or ad creative by showing them to different segments of your audience. By analysing how each version performs, you can identify which one drives better results, whether that's increased conversions, higher click-through rates, or improved user engagement.

They should be proficient in using A/B testing tools and have experience designing and implementing tests across various platforms. Excellent analytical and communication skills are crucial for interpreting results and presenting actionable insights.
