11 Best A/B Testing Tools in 2021 (Ranked and Reviewed)

By Hanson Cheng

August 19, 2021


A/B testing is a powerful tool that marketers use to improve conversion rates. The first step in A/B testing is finding the right tools for your business.  

There are many different A/B testing software tools on the market, but not all of them are created equal. 

A/B testing tools can range from simple split tests to complex multivariate tests.  

One test can be as basic as just testing two versions of a headline. Whereas a complex test would involve different variables such as page layout, text color, and advertisement placement.

To do that we've put together the top testing tools on the market and ranked them according to features, usability, and price. 

However not every customer is the same so it's important to choose the best conversion rate optimization platform that makes the most sense for your business.

What are the Best A/B Testing Tools on the Market?

Here you'll find my list of the best A/B testing tools to boost conversion rates.

Optimizely is an A/B testing tool, visual editor, and personalization engine that uses data to build better experiences. They offer A/B tests for web pages, mobile apps, emails, and more. It has been used by some of the biggest companies in the world like Airbnb, Amazon, and Google.  

Optimizely works by allowing you to have complete control of your web pages and mobile apps. You can create experiments in a few minutes without code or IT support. 

Even though it may seem like a complex testing platform, it is actually quite user-friendly and allows you to get highly advanced targeting of your audience in real-time. 

One of the best features of Optimizely is that they're simple and can be streamlined with templates from start to finish.

Key Features

  • Personalization of your content. This can help boost engagement. It allows you to address the needs of specific audiences and easily tailor the message to suit their needs.
  • Customize messages to ensure your clients are getting the right information at the right time. Tests can be updated in a few clicks with no coding required. This makes it easy to update your A/B test without needing any help from IT specialists.
  • Inbuilt reporting dashboard that provides insights into your experiments and tells you whether they're successful or not. You'll know what works best for each audience segment so that you can make an educated decision about future versions of the product or landing page layout.
  • Drag and drop visual editor for email campaigns to customize color schemes, build content blocks, and more. Customize your next email with this unique tool that provides a drag-and-drop interface so you can choose from predefined layouts like newsletter or preheader text block.
  • Multivariate testing can help identify from all the data, what change (if any) affects your website's performance so that it keeps improving the user experience and converting visitors into customers.

Optimizely doesn't display any pricing on their website and is available upon request. They are obviously targeting bigger brands here and that comes with an enterprise price tag but we're not talking about basic tools here. 

Optimizely is a leading program that uses multivariate testing to optimize websites. By making changes to multiple pages and then analyzing the results, it can determine what tweaks will yield improved conversion rates for each website visitor type.

Do you want to increase your conversion rates?

AB Tasty is a personalization platform that helps businesses drive more conversions and a faster ROI. They offer the most complete suite of tools for marketers, including email marketing, website personalization, customer segmentation, and CRM integration.

AB Tasty will help you create personalized content for each individual visitor on your site with their powerful A/B testing tool. You can also use their advanced analytics to see how different segments are interacting with your website or app so you can optimize it accordingly. 

AB Tasty's goal is to help you make better decisions about what content to show customers based on their interests and behaviors online.

  • Tools like AB Tasty provide you with an inbuilt reporting dashboard that quickly lets you know which variants of a page or product are the most successful from your test results.
  • Conduct multiple experiments through split URL testing.
  • Multivariate tests and split testing as standard.

Even though AB Tasty is one of the most feature rich A/B testing tools on this list, they do work with enterprise brands, and as such you'll need to contact their sales team to schedule a meeting. 

After a recent update, many new types of testing features are now available. One such feature is the interesting funnel testing feature which enables you to experiment with changes across multiple pages at the same time without affecting conversion rates or success metrics on your other pages.

The different plans you can choose from are included in the comparison table below.

As you can see their plans are extensive and include plenty of features, so you can choose the best one.

You may have been hearing a lot about AI-powered marketing, so it’s time to see what it can actually do for you.

Adobe Target is the first and only platform that combines artificial intelligence with personalization tools and automation at scale, so marketers can deliver personalized experiences across every channel, from the web to mobile to TV. And they don’t just provide insights, they also provide solutions on how to implement them in your business.

You know you want more customers, but you're not sure how to get them or where they are going next? Well, with their AI-powered tools and machine learning algorithms, you can find out exactly who your audience is and what they care about most. 

You can then serve up content that resonates with their needs. That's why brands like Nike rely on Adobe for all of their digital marketing campaigns.

Pricing for Adobe Target is available on application through their website, but if you've already got most of the Adobe marketing package then it offers easy integration between programs. 

This may not be the prettiest user dashboards or quite as easy to navigate compared to other tools such as VWO and Convert, but it's the impressive machine learning that makes it a big hit with enterprise brands.

If you've been looking for a way to make your website more personalized and engaging, but don't have the time or budget to do it, then Google Optimize is a free tool that helps you create personalized experiences and run website tests.

Optimize is used through the Google Chrome extension, whereas Google 360 is the paid version that can test multiple variations of a page. 

It’s easy to use, so you can get started in minutes. You don’t need any coding skills or complicated software, just your creativity and imagination. Plus it's completely free!

With Google Optimize, you can test different layouts of your pages to see what works best for your audience. You can also A/B test headlines, images, buttons, and more to find the perfect combination for conversion rates. 

With Google's new Personalization Engine, it will help you personalize the content on the go based on who visits your site. A bit like showing them their favorite products when they visit a product page.

Key Features

  • Easy integration with Google Analytics.
  • A free option for multivariate testing and A/B/n split testing.

This is a good starting point for those businesses looking to get familiar with what A/B testing and split testing, in general, has to offer before diving into more expensive testing tools. 

Enterprise brands will find that it may be better to sign up for the Google Analytics 360 suite of products which automatically includes Optimize 360, but if you're just starting out this split testing tool has everything you need.

Kameleoon is a full-stack personalization platform that helps marketers, developers, along with product teams to boost engagement and conversions. They have helped companies like Coca-Cola, Nike, and Spotify increase their revenue by over $1 million in just one month.

While you don't necessarily need any technical experience to get started with Kameleoon, having some sort of knowledge with CSS and Javascript will be useful for advanced modifications. 

With their A/B testing toolkit, you can create personalized experiences for each of your customers without having to code anything yourself. You can also use our analytics dashboard to see how different versions of content perform against each other so you know which ones are the best performers.

Key Features

  • API integrations to help you get started quickly with any app or website.
  • Easy to understand reporting interface.
  • Connect third-party analytics tools such as Google Analytics and AT Internet.
  • A smart visual editor that saves you time and minimizes mistakes.
  • Powerful split testing AI algorithms.

Pricing is tailored to your exact requirements. 

A truly enterprise piece of software, Kameleoon is designed to be intuitive and easy to use. It's rare for an enterprise CRO tool to have this design quality but you'll feel the benefits every time you use it. The best thing about its UX is that new team members find it effortless too, enabling them to get started on their projects right away.

Oracle Maxymiser is the leading marketing automation platform for digital marketers.

We help you create personalized and relevant customer experiences across all channels, including websites, mobile apps, email campaigns, and more. Our powerful technology helps you deliver better results with less effort.

With our intuitive interface and robust feature set, it’s easy to build a campaign that will engage your customers on every channel they use from web pages to emails to social media posts. We have everything you need to measure success at your fingertips including reporting tools that provide deep insights into how well your campaigns are performing so you can make adjustments as needed.

  • Predictive insights with heatmaps to see how your customers interact on the page.

Pricing is only available through submitting a form. However, similar to Adobe, if you have the Oracle suite of products it will make sense to seemingly connect Maxymiser to the cloud. 

Oracle's system is not perfect, but it does have some great features. For example, the length calculator provides a beneficial estimate on how long tests need to run before reaching statistical significance and there is no flickering or broken content when they do run.

Freshmarketer combines all the tools you need to run a successful marketing campaign in one place. Making it easy for marketers of any skill level to set up and manage campaigns across different channels.

Marketers everywhere are always looking for new ways to stay ahead on their game, which is why Freshworks created an automation platform designed specifically with today's marketer in mind.

Freshmarketer provides a user-friendly interface for creating A/B testing and split URL tests. The WYSIWYG editor simplifies the process of designing these types of experiments, but you can also take advantage of their reporting features to view results in real-time.

Freshmarketer is a great option for newcomers or online businesses with modest needs who want to enter the world of conversion optimization.

As an entry platform into Conversion Optimization, it provides small and medium-sized enterprises (SMEs) with moderate requirements access to sophisticated solutions in this rapidly evolving field.

Zoho PageSense is a two-in-one conversion optimization and personalization platform with some of the lowest entry prices in the game. The Zoho team doesn’t restrict pricing on its plans so you get access to everything that their cutting-edge, low-cost platform has to offer.

Your fee will depend on how many monthly visitors your website or business generates per month but rest assured, it won't be more than $10/month for up to 10 million visits!

Key Features

  • Set website goals and measure their performance.
  • Heatmaps that show you where to place important features from where your customers are scrolling.
  • A/B Testing.
  • Split URL testing.

One of the easiest plans to go through in this list. Zoho Pagesense has three very affordable plans for you to choose from. Of course, you'll save more (20% off) by paying yearly rather than monthly.

The plans all scale depending on how many monthly visitors you get but they range from 10,000 all the way up to 1 million monthly visitors.

In these plans below, we'll look at the base rates for 10,000 monthly visitors.

What's included:

  • 3 projects. 
  • 6 months data retention. 
  • 20 custom dimensions.
  • 20 goals.

Plus, at this price point, there are few other options that offer comparable benefits so I wholeheartedly recommend PageSense to SMEs or entrepreneurs looking to start their own company.

A/B Testing Tools FAQ

How do you perform an A/B test?

To perform an A/B test, you need to establish a goal and create A/B variants. An A/B variation is the different versions of an element that are being tested in order to see which one performs best. 

You'll then need to run a test that consists of two or more variations, where elements on each page can be changed, such as design changes, pricing change for products, content changes, and A/B testing.

How do you decide between A/B Testing Tools?

There are many factors to consider when deciding between A/B testing tools. The first is the number of conversions you're willing to lose in order to gather accurate data. 

The next is your goals. A website A/B test might focus on increasing the conversion rate, while a mobile app A/B testing tool may improve customer retention or engagement.

You'll also need to consider which A/B testing tools are the easiest for your team to use and how much of a time commitment A/B testing is for your team.

What is A/B testing in digital marketing?

A/B testing is a method for comparing two versions of something to identify the better one. A common A/B test in digital marketing is an A/B split test, where marketers create two or more variations of content and ask visitors which version they prefer through on-site polls (click here). 

The goal of A/B testing is to catch people's attention so they'll buy the product or service. A successful A/B test could lead to increased customer retention rates, reduced marketing costs, and increased conversion rates.

What is multivariate testing or split testing?

Multivariate testing is A/B testing on a bigger scale. It is when you want to A/B test more than two variations of content so that you can have an educated decision about future versions of the product or landing page layout. 

With standard split testing, if conversion rates are low and your goal is increased customer retention, you may want to A/B test different variations of your landing page in order to determine which layout resonates best with customers.

What are A/B testing platforms?

A/B Testing platforms are A/B testing tools that are designed to work on a website or mobile app. A lot of A/B testing platforms provide A/B split tests, but not all do. 

An A/B split test is when you create two or more variations of a page and ask visitors which version they prefer.

Bottom Line

A/B testing is an important tool for marketers to use when they want to increase conversions. It allows you to get better insight into what your customers like or don’t like and the best way of getting them engaged with your product, service, or content. 

Plus it helps you avoid wasting time on strategies that just won't work. It's crucial to focus on user behavior and how it affects your business. 

If you're after some other tools I suggest you look at Unbounce and SiteSpect. 

In this list, we’ve covered the top testing tools for just about every possible need you could have, from free options to enterprise solutions and easy-to-use optimization tools that are available right now. 

You can't go wrong with any of these platforms but it's important to find a solution tailored specifically for your needs.
