Does your website engage your audience and consistently convert visitors into loyal product users? Are your headlines, CTA buttons, and other site elements driving conversions? How can you know?
A/B testing tools take the guesswork out of your CRO efforts, letting you test different versions of your web pages to see which elements engage or confuse visitors, so you can make changes that delight and convert them into customers.
This type of software helps you run split tests and understand user behavior—how people react to alternative product versions, such as different website messaging and designs—giving you data you can use to create new features or pages and improve your existing ones.
But choosing the best A/B testing software for your business can be difficult, especially with so many options available. We rounded up 7 of the best A/B testing tools and give you 10 tips on how to choose the right one for your business, so you can eliminate guesswork and make data-driven decisions to improve the user experience (UX), perfect your product’s functionality, and boost website conversions.
7 best A/B testing tools to delight customers and boost conversions
To begin running tests, you need two types of A/B testing software: quantitative and qualitative A/B testing tools.
Quantitative A/B testing platforms show you
How many people responded better to a different version of your web page
The number of visitors who became leads or customers on a page variant
How many times a visitor clicked a call-to-action (CTA) button on different page variations
And qualitative A/B testing tools help you understand
Why your visitors take certain actions
How user behavior results in sign-ups, purchases, or other desired actions
Combining qualitative and quantitative A/B testing tool insights gives you a full picture of your users’ experience—you learn about the elements they find most interesting or frustrating and why, so you can make changes that positively influence their behavior and convert them.
Let’s go over the top A/B testing tools to incorporate into your workflow.
1. Contentsquare
Contentsquare (that’s us 👋) is an all-in-one experience intelligence platform that teams can use to monitor their site’s digital experience. With both quantitative and qualitative tools and capabilities, our platform allows you to add deeper insights to your A/B tests and understand the motivations behind user actions.
Contentsquare captures A/B test insights, showing you how people interact with different elements of your product. When you truly understand users' preferences and frustrations, you can make changes that positively influence their actions.
Contentsquare puts all of your most important A/B test statistics at your fingertips
How to use it: Contentsquare integrates with many well-known A/B testing solutions—like AB Tasty, Kameleoon, and Optimizely—but there are multiple ways to use Contentsquare for A/B tests without prior coding or technical expertise.
Use heatmaps to identify elements that convert or frustrate users
Heatmaps show you which elements of a web page people click on (or ignore) most frequently to inform your A/B testing hypotheses, so you can make changes that convert more users into customers.
Say you create a test in your A/B testing tool (like AB Tasty) to show two different variations of your product pages to different audiences. Instead of wasting hours figuring out exactly what to improve without the additional context, you can use Contentsquare’s zoning analysis to see which elements website visitors interact with the most on each test variant.
Contentsquare’s side-by-side analysis in a single view lets you quickly analyze and optimize A/B test performance
Understand customer journeys to uncover where users get stuck or convert
A visual customer journey analysis shows you how people progress from page to page, where they get stuck, or where they drop off during your experiments. For example, if you’re A/B testing two versions of your product pages, Contentsquare’s Customer Journey Analysis shows you exactly how users navigate each one. You’ll know which version is leading to more conversions and where visitors are hitting roadblocks, helping you make smarter changes.
The color-coded and intuitive dashboard helps you quickly spot the biggest opportunities to make improvements. Plus, you can compare journeys side-by-side, whether users come from different campaigns or traffic sources, to see how their behavior varies.
Journey Analysis in Contentsquare allows companies to see users progress through your site, page by page, from entry to exit
For example, RingCentral, a leader in AI-powered communications, had plenty of traffic on their website but struggled with low conversions. They needed a clearer view of user behavior to understand where visitors were dropping off.
They used Customer Journey Analysis to track how users navigate the site and found key areas for improvement, like their lead capture forms. By running A/B tests and using Contentsquare insights, they redesigned these forms and saw a 25% boost in conversions.

The biggest resource benefit to me of Contentsquare is time. To get that level of insight and to drive that many beneficial tests we’d really need another 3 full time members of staff, but by using Contentsquare we can drive insights across the whole digital team.

Use session replays to compare user behavior on different versions of a page
Session replays allow you to review different versions of a page you're A/B testing, so you can see how users interact with each and determine which is more effective.
Contentsquare’s Session Replay integrates directly with heatmaps and Voice of Customer (VOC) tools to give you even more context behind user behavior.
Sort Contentsquare replays by frustration level to uncover user pain points
Use surveys to find out why users aren’t taking certain actions
The Contentsquare surveys capability lets you capture in-the-moment feedback during experiments.For example, during an A/B test, you can use Contentsquare to create a survey that pops up after users spend a certain amount of time on the different versions of your product pages.
Your survey should ask questions like:
If you could change anything on this page, what would it be?
What could we do to improve?
What is stopping you from purchasing today?
The answers will help you better understand how users interact with your product pages and where they may encounter issues.
If you want to accelerate the process, use one of our survey templates or sit back as our AI-powered research software automates and quantifies user issues with AI summary reports, sentiment analysis, and automated tags.

How to pick the best A/B testing software for your business
Choosing the best A/B testing tool for your business helps you uncover the insights you need to start delighting and converting your audience into leads and paying customers.
Here are 10 tips to help you decide:
1. Identify your needs
Before choosing any A/B testing software, ask yourself, "What kind of tests do I want to run? What features do I need? What is my budget?" These questions narrow down your options, so you can select an A/B testing software compatible with your business goals.
2. Ensure the tool has the features you need
Look for A/B testing software with various features that allow you to gather quantitative and qualitative user data. The more relevant features the software provides, the more insight you'll have into the product experience to create delight for different user personas.
3. Consider the level of expertise required
Your A/B testing tool should be user-friendly and easy to use, even for non-technical users. Look for software that has an intuitive user interface and clear instructions so you can create, run, and analyze A/B tests quickly and with ease.
4. Evaluate integrations
Your A/B testing software should integrate with your existing tech stack, which includes your website platform, CRM, and analytics tools (like Google Analytics). Choose a tool that integrates seamlessly with your existing tools to reduce disruptions and simplify data management.
5. Check pricing and scalability
Consider the A/B testing software’s pricing structure, including additional fees for add-on features or increased traffic volume. Look for software that offers transparent pricing with no hidden fees or surprises, and choose a tool that’s easy to scale, especially if you expect significant traffic or user volume growth.
6. Read reviews and compare features
Research the software vendor's reputation and read user reviews—from product managers and marketers—to learn about other brands’ experiences with the tool. Compare A/B testing features and pricing to other tools to understand the software’s strengths and weaknesses, and to make an informed decision.
7. Test the tool before committing
Consider A/B testing tools with a trial period or a free software version that lets you test the software before purchasing it to ensure it meets your needs.
8. Look for customer support and training
Choose A/B testing tools with excellent customer support and training resources. Look for software vendors who offer detailed documentation, video tutorials, and responsive customer support.
9. Ensure it has analytics and reporting features
Your A/B testing software should provide detailed analytics, reporting, real-time data, and easy-to-understand insights. Look for a tool with clear visualizations, heatmaps, recordings, and statistical significance indicators.
10. Prioritize security and compliance
Consider the software's security features and compliance with data privacy laws such as GDPR, CCPA, or HIPAA. Ensure your A/B testing software is hosted on a secure platform with adequate safeguards to protect your data and users’ privacy.
Combine digital experience insights with A/B test results to increase your site’s conversion rates
A/B tests tell you which version of your website or product performs better in terms of conversions, but they don't provide insight into why users behave the way they do.
Using digital experience insights from tools like heatmaps, surveys, and session replays helps you understand why users prefer one version of your site over another. And when you deeply understand user behavior, you identify areas they struggle with on your site quicker, prioritize the changes likely to have the most impact, and create more customer delight.
