How I Selected the Best A/B Testing Tools
Maybe you’re wondering how I selected the best A/B testing tools? To build this top 10 list, I evaluated and compared a wide range of split testing software with positive user ratings.
After determining my long list of suitable apps, I further honed my list by using the selection criteria below to see how each platform stacked up against the next one. I also drew on my years of online marketing experience to pinpoint the features that add a lot of value.
Selection Criteria
Here’s a short summary of the main selection and evaluation criteria I used to develop my list of the best A/B testing tools for this article:
Ease of Use
The A/B testing software you choose should be easy to use and navigate. You don’t want to spend a lot of time trying to figure out how to set up and run tests. That’s why I selected software with a user-friendly interface with clear instructions.
Statistical Significance
The software should have a reliable statistical analysis engine to determine whether your results are statistically significant. Without statistical significance, you won’t know whether your test results are reliable or not.
Multiple Test Types
I chose software that allows you to run different types of tests, such as A/B tests, multivariate tests, and split URL tests. This will give you more flexibility to test different aspects of your website or mobile app and confirm different types of hypotheses.
Reporting and Insights
The software should provide comprehensive reporting and insights into your test results. I selected software that offers easy-to-read reports, visualizations, and recommendations for how to improve your website based on your test results.
Software Integrations
Any good A/B testing tool will have integrations with popular marketing, beta test management software, and business software tools. These are essential to getting the best value from the data delivered by the split-testing tool.
Pricing
I expect any software application to offer multiple pricing plans to suit the needs of different users. Each tool should be affordable with respect to the volume of traffic being tested. I also recommend taking advantage of a free trial to get your hands on the software before you commit.
A/B Testing Tools: Frequently Asked Questions
Split testing is incredibly important but not always easy to get right. Here are the questions I most frequently receive on this topic:
What is an A/B/n test?
An A/B/n test is a type of experiment where more than two variations of a website, email, or advertisement are tested against each other to identify the version that performs best. It allows businesses to compare multiple variations of a single element to find the best option, rather than just two. A/B/n testing can help marketers and ecommerce vendors fine-tune their digital marketing efforts by testing multiple variables and achieving better results.
What main features are included in A/B testing software?
A/B testing software typically offers the functionality to create and manage multiple tests simultaneously and the ability to define test variables and traffic allocation. Other features may include statistical analysis of test results, and comprehensive reporting and insights.
How does page flickering affect A/B testing?
Page flickering can significantly affect A/B testing results by creating a poor user experience that skews user behavior and impacts the test validity. Page flickering occurs when test variations take too long to load, causing the original version of the page to appear briefly before the test variation is displayed. This creates confusion for users, causing them to behave differently than they would on a fast-loading page.
When is Google Optimize shutting down and why?
Google Optimize 360 will no longer be available after 30 September, 2023. Experiments and personalizations can continue to run until that date. This move is part of Google’s larger effort to migrate its analytics and testing features to the new Google Marketing Platform, which offers more advanced and streamlined features for marketers.

A/B testing tools are essential for marketers looking to optimize their website, email campaigns, and other digital marketing efforts. With a wide range of options available, businesses can choose the tool that best meets their needs and goals, whether they’re looking to test a single element or multiple variables. By using A/B testing tools, you can make data-driven decisions that improve your online presence, generate more leads, and increase conversions.
