Top 15 A/B Testing Tools in 2025

Table of Contents

A/B testing has a key place in every marketing expert’s armory. Even if you think you’ve got great marketing instincts, there’s only one way to know whether your ad, landing page, or entire website could be performing better…

…and that is to conduct A/B testing.

Using hard data to make decisions will always outperform “gut feelings” in the long run.

A/B testing tools are essential for conversion rate optimization (CRO), as they help improve customer experience and increase conversions through data-driven insights.

In this article, we’ll explore the importance of having a great A/B testing tool and help you figure out which of the many A/B testing tools is best for your unique needs.

Let’s get started!

Why do you need an A/B testing tool?

While it is possible to conduct A/B testing (also known as split testing) manually, there’s really no reason to do so. Manual A/B testing has many limitations: it’s resource-intensive, lacks scalability, and leaves you open to human error.

Nowadays, the best A/B testing tools have incredibly advanced features and are easy to use. Whether you want to run multiple tests or investigate whether your personalization features are working well, there’s an A/B testing tool for you.

Here are four benefits of using a full-stack experimentation platform for your online business.

1. Data-driven decision making

As we mentioned in the intro, running tests on your marketing campaigns helps ensure that you’re making decisions based on data.

When you analyze user behavior and gain statistically significant results from your A/B testing, you can gain deep insights about which marketing messages and tactics resonate with your target audience.

2. Improved conversion rates

Using A/B testing tools can help you fine-tune everything from landing pages and product pages to your checkout processes.

Even small changes to details like the color of a call-to-action button or the wording of a headline can have huge impacts on your conversion rates.

3. Enhanced user experience

A/B testing helps you identify elements of your website and customer experience that may frustrate or confuse users, thereby improving user engagement by allowing businesses to experiment with different design elements and features.

Whenever a potential customer is unsure of what step they should take next or struggling with website functionality, they’re likely to close your website and never return again.

4. Revenue growth

By optimizing your website and marketing campaigns based on test results, you’re more likely to generate higher revenue.

When you test variations of your website to see which performs best, you’re going to be making more revenue from the same amount of traffic that already hits your website. That’s the magic of conversion optimization!

What makes a great A/B testing tool?

Here are some key features that can take an A/B testing tool from being simply OK to outstanding.

1. User-friendliness

An A/B testing tool should have an intuitive user interface, allowing users to easily set up experiments and view their results.

Since many ecommerce stores have multiple people working on their campaigns, tools that allow for easy collaboration provide an advantage.

2. Reliability

It should go without saying, but you want to make sure that the A/B testing tool you chose doesn’t have issues with bugs and glitches. 

Not only can buggy software make you unsure about whether to trust your test results, it can also interfere with your sales and product launches. It’s always a good idea to check whether customer reviews of the A/B testing tools you’re considering mention issues with reliability.

You also want to make sure that all the data your testing tools collect is trustworthy. The A/B testing software you use should be compliant with the GDPR and any other local regulations.

3. Scalability

An A/B testing tool should be scalable, which means that it can accommodate a growing number of experiments and visitors without sacrificing performance or data accuracy.

As your business grows, you’ll have to launch split tests more regularly, and you don’t want to run into any limitations.

Depending on the size of your business, it might be worth shelling out for an enterprise price tag if you get access to an excellent experimentation platform that will serve your needs for a long time.

4. Robust data analysis

The best A/B testing tools feature experimentation capabilities that allow you to conduct advanced testing. If you want to deliver a personalized customer experience to your customers, for example, then you need to use a tool that’s capable of tracking advanced segmentation. 

Other complex tests you can benefit from include funnel tracking (A/B testing the entire customer journey), visitor behavior tracking (analyzing mouse movements and clicks), and statistical analysis (such as a statistical significance calculator).

FAQ

What are the major types of A/B testing?

In essence, A/B testing (or split testing) is about comparing two versions of a webpage, the “A” version and the “B” version, to see whether one outperforms the other.

There are also other types of testing, including:

  1. Multivariate testing: Here, you create multiple variations of a few different elements on a page to find the best combination.
  2. Split URL testing: It tests entirely different web pages (URLs) against each other, which is useful for testing major design or content changes.
  3. Sequential testing: This involves testing a series of variants sequentially, with each variant being compared to the best-performing one so far. It’s used to make changes to a live website gradually.

How do I choose an A/B testing tool?

There are many A/B testing tools on the market, which can make it difficult to know which is the best one for you. When choosing an A/B testing tool, you should consider the following factors:

  • Make sure it offers the features you need, like multivariate tests or cohort tests for personalization.
  • Read reviews to find out how easy it is to use and whether it fits your team’s skills.
  • Check whether it integrates with your other tools, like Google Analytics or email platforms.
  • Keep your budget in mind and consider how pricing can change as you grow.
  • Investigate whether the tool has a responsive customer support team.
  • Make sure it follows data rules and keeps data safe.

What is the typical duration for an A/B test?

This can vary, but A/B tests generally run for one or two weeks. The key is to balance getting enough data for reliable results without making the test too long.

What happened to Google Optimize?

Google Optimize, Google’s A/B testing and web optimization platform, was officially sunset on September 30, 2023. Google decided to discontinue both Google Optimize and Optimize 360 as part of a broader shift in its product offerings. Google stated that it intends to integrate more testing and web experimentation capabilities directly into Google Analytics 4 (GA4) in the future, although a direct replacement for Google Optimize has not been announced as of now.
