What Is A/B Testing?
Also known as split testing, A/B testing is comparing two different versions of a digital asset; this could be an email, advert, web page, even a call to action. The result will show which one is performing better.
The process is carried out by splitting your audience into two, or more, groups. The two different digital versions, version A and Version B, are seen by the split groups (only one group will see one version). Tracking can then be carried out based on specific metric performances; click-through rates, engagement levels and most important, conversions.
This is an incredibly powerful practice.
Why A/B Testing Matters in 2025
Brands are under more pressure, as digital space becomes more competitive, as they need to create content that creates an impact and wants to be seen. A/B testing has become more valuable than ever, and here is why:
Data-Driven Decisions Beat Assumptions
The idea of what ‘should’ work is a strong opinion by Marketers, though the consumer can be full of surprises, which is why using A/B testing works. It removes the bias by putting real behaviour at the centre of decision making.
Example: You might think that a big red button will work better than a smaller green one? Testing this with the audience will give you the real data.
Improved Conversion Rates
The smallest changes can make noticeable improvements in performance of PPC ads to landing pages. A tweaked headline or stronger CTA could significantly boost your conversion rate.
A/B testing helps you ensure that you squeeze the most out of your ad spend, especially with paid digital campaigns where every click and impression costs you money.
Enhanced User Experience
This is not just about conversions, it is about creating a smoother experience for your users. You can identify what is keeping your visitors engaged in your content for longer, by testing the different layouts, content length and flows, and navigation ease.
For an e-commerce business, this can mean high value orders and less abandoned baskets.
What Can You A/B Test?
Almost anything can be tested in your toolkit. Here are some examples:
- Email campaigns: subject lines, send times, design, CTAs
- Web pages: headlines, images, button placement, copy length
- Landing pages: form fields, social proof, layouts
- Paid ads: visuals, ad copy, target audiences
- Social media posts: captions, hashtags, posting times
TP: Test one variable at a time, so you understand what is driving the different performance metrics.
Best Practices for A/B Testing
See the below tips for how to get the most out of your tests:
- Have a clear goal: Know what, and why, you’re testing. Whether it’s to increase sign-ups, to reduce bounce rate, or to boost engagement.
- Test one thing at a time: Changing too many variables can muddy your results not knowing which change is making which impact.
- Use a large enough sample size: Ensure that your test reaches enough people to gain credible and reliable insights.
- Run the test long enough: Let it run for a few days, or longer depending on weight of traffic, to avoid misleading data.
- Analyse and act: Review the data, identify the greatest positive impact, and implement the changes…then test again. Continuous improvement is the goal.
