Definition of ab testing
A/B testing, also known as split testing, is a marketing strategy that involves comparing two versions of a webpage, email, or advertisement to determine which one performs better in terms of conversion rates, engagement, or other desired metrics. This method allows marketers to make data-driven decisions by testing variations of design elements, copy, or calls-to-action, and analysing the results to optimise their campaigns. By identifying the most effective version, marketers can improve their overall marketing efforts, increase customer satisfaction, and ultimately boost their return on investment.
An example of ab testing
Here is an example of how it works:
Growth Method wants to test the effectiveness of two different pricing plans for their SaaS platform. They create two variations of their pricing page:
Variation A: A three-tiered pricing plan with a Basic, Pro, and Enterprise option.
Variation B: A two-tiered pricing plan with a Standard and Premium option.
They randomly assign 50% of their website visitors to see Variation A and the other 50% to see Variation B. Over the course of a month, they track the number of sign-ups for each pricing plan and the overall revenue generated from each variation.
At the end of the month, they analyze the data and determine which pricing plan variation led to higher conversions and revenue. Based on the results, they decide to implement the winning variation as their new pricing plan.
How does ab testing work?
AB testing works by comparing two or more variations of a marketing element, such as a webpage, email, or advertisement, to determine which version performs better. Marketers randomly assign their audience to different groups, each exposed to a different version of the marketing element. They then measure the performance of each version based on a specific goal, such as click-through rates, conversions, or sales. By analysing the results, marketers can identify the most effective version and implement it in their campaigns, ultimately improving their overall marketing strategy and return on investment.
