How to A/B Test Your Sales Funnel

In the world of digital marketing, data is king. It's the compass that guides our strategies, the fuel that drives our campaigns, and the yardstick by which we measure success. One of the most powerful tools in our data-driven arsenal is A/B testing, a simple yet effective method for optimizing every aspect of your sales funnel. By comparing two versions of a webpage, email, or other marketing material, you can identify which one resonates more with your audience and drives more conversions. But how exactly do you conduct an A/B test? Let's delve into the process.

Understanding A/B Testing

A/B testing, also known as split testing, is a method of comparing two versions of a webpage or other user experience to see which performs better. You compare two webpages by showing the two variants, let's call them A and B, to similar visitors at the same time. The one that gives a better conversion rate, wins!

It's a direct, uncomplicated way to test changes to your webpage against the current design and determine which one produces better results. It's all about testing one version of a particular element against another version of the same element.

Why A/B Testing is Important

A/B testing allows you to make more out of your existing traffic. While the cost of acquiring paid traffic can be huge, the cost of increasing your conversions is minimal. A/B testing can be used continuously to keep improving a given experience, improving a single goal like increasing the conversion rate of a page over time.

It can also be used to test major changes, like a complete redesign of a page or a new headline. It's important to keep in mind that the changes you make are always hypotheses (e.g., "Changing the color of the CTA button from green to red will increase conversions") and A/B testing will prove or disprove these hypotheses.

Setting Up Your A/B Test

Setting up an A/B test involves a series of steps that ensure the test's success. These steps include selecting a testing tool, choosing what to test, setting your goals, and creating your variations.

There are several A/B testing tools available, including Google Optimize, Optimizely, and Visual Website Optimizer. These tools will randomly show one of your test variations to each visitor, and then track the visitor's interaction with your site.

Choosing What to Test

When deciding what to test, consider the elements that could have the biggest impact on your goals. These might include headlines, subheadlines, paragraph text, testimonials, call to action text, call to action buttons, links, images, content near the fold, social proof, media mentions, and awards.

It's also important to consider the location of these elements on your page. Elements above the fold (the part of the page that's visible without scrolling) will be seen by more people, and therefore have a bigger impact on your results.

Setting Your Goals

Your goals are the metrics that you're using to determine which variation is more successful. For example, if you're testing a product page, your goal might be to increase the number of people who add the product to their cart.

When setting your goals, be specific. Instead of aiming to "increase conversions", aim to "increase conversions by 15%". This will make it easier to determine if your test was successful.

Creating Your Variations

Once you've chosen what to test and set your goals, it's time to create your variations. These are the different versions of your page that you'll be testing against each other.

When creating your variations, only change one element at a time. This is known as "isolated testing", and it's important because it allows you to pinpoint exactly which changes had an effect on your visitors' behavior.

Running Your A/B Test

After setting up your test, it's time to start running it. During this phase, your A/B testing tool will collect data on how visitors interact with each variation of your page.

It's important to run your test for a sufficient amount of time to ensure that your results are statistically significant. This means that the results are not due to chance, but are a true reflection of the differences between your variations.

Interpreting Your Results

Once your test has run for a sufficient amount of time, it's time to analyze the results. Your A/B testing tool will provide you with data on how each variation performed in relation to your goals.

If one variation significantly outperformed the other, then you have a clear winner. If the results are close, you may want to run the test again or test a different element.

Implementing Your Findings

After interpreting your results, it's time to put your findings into action. If one variation was clearly more successful, implement that change on your site.

Remember, A/B testing is a continuous process. Even after you've made one improvement, you can continue to run tests and make further improvements. This is the key to a truly optimized sales funnel.


A/B testing is a powerful tool for improving your sales funnel. By systematically testing different variations of your site, you can identify what resonates with your audience and drives conversions.

Remember to be methodical in your testing, changing only one element at a time and running your test for a sufficient amount of time. With patience and persistence, you can use A/B testing to significantly improve your sales funnel and boost your bottom line.
