At this point in time, the field is flooded with solutions. Finding a proper A/B testing tool isn’t the problem anymore. Now, the problem is choosing the right one.
If you work in conversion optimization – whether at an agency, in-house, or as a consultant – you almost certainly run A/B tests.
Though you could hire someone full time to sift through and analyze the pros and cons of each tool, it’s easier to learn from the experience of others and make a decision based on that.
To help you with that, we’ve assembled a list of the most popular a/b testing tools and corresponding reviews from A/B testing experts to help you in your decision making process.
Without further ado, here are the top A/B testing tools used by experts (click below to navigate to a specific tool):
- AB Tasty
- Adobe Target
- Dynamic Yield
- Google Optimize
- Sentient Ascend
AB Tasty is a reasonably priced and simple to use tool that serves as a good starting point for companies just starting in conversion optimization.
AB Tasty offers A/B testing, split testing, multivariate testing, and funnel testing capabilities. Using AB Tasty’s visual editor, you are able to quickly put together variants and tests and receive real-time reports with confidence levels on your goals. At the same time, you have full control of testing through advanced targeted scenarios, allowing you to trigger tests based on URL, geolocation, demographics, etc. You are also able to enrich the platform’s data by integrating existing data from CRMs and DMPs.
Chloe O’ Keeffe, Associate Conversion Consultant at Conversion.com, shares some pros and cons:
The basic starter plan rounds out to $249/month and includes 50,000 unique tested users and carryover of unused credit.
Adobe Target is a popular enterprise tool that combines targeted testing and personalization.
Adobe Target walks you through a three-step workflow where you first create the variant, then target the variant based on visitor segmentation, and lastly customize your goals and settings for the test. Based on this emphasis of targeting, it should come as no surprise that Adobe Target’s most exciting feature is automated personalization.
Target’s self-learning algorithm continually and automatically adjusts itself to make associations between visitor behavior and content in order to give you the best results possible. Real-time adaptation of content can help you better meet the needs of diverse visitors.
Here’s a review from Sean Patterson, a Digital Analytics and Optimization Consultant at Conversion.com:

Apptimize is a testing tool focused on mobile optimization and is a perfect choice if mobile is an important platform for your business.
Apptimize offers you a full control visual editor where you’ll be able to rapidly create new variants and target them at different user segments. You’ll also be able to add dynamic variations and code blocks that support Objective-C, Swift, Java, HTML5, Xamarin, and React Native. Their randomized experiment methodology also ensures your experiments will return statistically significant results.
We sourced reviews for Apptimize from G2Crowd. Here’s an anonymous review talking about some things they liked about Apptimize:
It’s easy to set up and track tests. The code needed to implement the tests is straightforward. It integrates with Localytics.
And here’s a review discussing some disappointments:
“The real-time changes that we can deploy are acutally limited in the scope – so, not all of our original goals can be met with this tool. Also, we have to plan in advance what sections of parts of our app we would like to change, and only after that we can start using this feature, which means that there is a lag/delay between the time that we want to change something and the time when it actually becomes a reality. For example, with our sprint structure this delay can be as long as 3 – 4 weeks.”
Apptimize starts at $995/month and supports up to 100,000 monthly active users. You can also request a custom plan based on your needs.
ChangeAgain.me provides a visual interface to Google Experiments for A/B Testing.
A good solution for those companies that already have Google Analytics and want to try split testing.
They bill based on the number of tests you run, not the number of visitors as other split testing solutions do.
No coding skills necessary. You can launch new tests with a point-and-click visual editor
Conductrics is an advanced tool that offers methods from AB Testing blended with Machine Learning to deliver optimal experiences, for each user, automatically.
You can use it as either a server-side or client-side tool, and you can pretty much customize it in anyway you’re trying to use it.

- Creation of custom actions enables us to bridge the gap between our online and offline tests by injecting code changes directly onto the page.
- The test segmenting features are very robust, actions can be triggered by device, ip, cookie, audience type and at specific times of day allowing us to test whatever we want, when we want.’
And some cons:
- “We’re not using all the features of the tool, there’s so much to choose from it’s sometimes overwhelming. The support team however are superb and have always been able to help.

Optimizely is one of the most popular, WYSIWYG experimentation tools and a go-to choice when working with any size company.
At the root of it, Optimizely is focused on web experimentation and personalization. They offer easy-to-use A/B and multi-page experimentation and supports experimentation across platforms (web, mobile web, iOS, Android, etc.) and shows you results in organized formats using their user-friendly Stats Engine.

Diane Leung, Associate Consultant at Conversion.com, shares her thoughts:
Optimizely’s Pay As You Go is a good way to go if you’re just starting out and costs $49 for every 1,000 monthly unique visitors you test on. Even if the same visitor sees many experiments, the visitor is still only counted once.
Qubit is a testing platform focused around personalization, making it one of the strongest segmentation tools on the market.

- “Great A/B test ideas based on both quantitative and qualitative evidence.
- The Qubit consultants and engineers we have worked with have an excellent ‘can do’ attitude.
- Excellent communication and clarity on test results.”
From the same review, the cons are:
- “There is room for improvement on the velocity of getting new tests developed and QA’d.
- I would like to see improvements to the exit survey interface to make it easier to flag, categorise and disseminate feedback to different areas in the business.
- Depending on the test/experience it can add extra weight to page load times and cause ‘flicker’.”

Sentient Ascend is a new generation testing tool that merges machine learning algorithms with conversion optimization.
The concept is simple, genetic algorithms can find optimal combinations of design choices faster and with greater accuracy than humans can. By isolating the best local maximum, the machine assembles the highest performing segment and pushes forth optimal personalization solutions. Of course, this also means you can test all of your ideas at once and see evolution in action.
Here’s Guido Jansen from Euroflorist explaining some pros and cons of the tool:
Viljo Vabrit, Managing Director at CXL Agency, wanted to point out a few issues with the tool as well:
- “You can’t edit active tests. If there’s a small bug or something breaks due to a change in the control you either stop the experiment and create a new one or contact the support and hope they can make the change for you as soon as possible. Same also goes for the changes related to audience and URL targeting.
- QA-ing everything is a pain. And I am not talking about going through the thousands or even millions of possible combinations. Just previewing a specific combination requires you to understand the complex query parameter logic in place.
- The visual editor can be quite slow and crashes occasionally, sometimes with all of your changes.”
Pricing for Sentient Ascend is available on request.
SiteGainer is a company that offers a full suite of conversion optimization tools, including A/B testing, multivariate testing, personalization, heat maps, popups, and surveys.
