A/B testing is a popular digital marketing strategy used by conversion specialists when trying to improve website conversion. This test involves a side-by-side test of two or more options to find which one performs better than the rest.
Let’s understand A/B testing, its types, benefits, and examples to ensure every beginner who hasn’t tried A/B testing can get off to a good start.
What is A/B testing?
The A/B testing is a comparison of two or more cases only to find out which works better than the other one. The purpose of an A/B testing campaign is to uncover the better-performing option out of all.
It’s a powerful analysis strategy used in online advertising, email marketing, social media publishing, website conversion, and several other areas.
The goal of an A/B testing campaign is to see which option outperforms the other one.
For instance, a brand does side-by-side testing of two Facebook ad units under the same ad set. It can see which ad unit performs better than the other one by comparing the ad results.

Types of A/B tests
Three types of A/B testing are widely popular in the digital marketing space:
1. Split testing
Split testing is a type of A/B testing in which a user creates a new version of an existing landing page, logo, or banner ad and compares it to the original to determine which one achieves better performance metrics. It works best when the user wants to overhaul the entire design of a landing page without altering the current version.
2. Multivariate testing
Multivariate testing is yet another useful A/B testing type that allows marketers to examine multiple variables simultaneously to identify the most effective combination of elements on a page. Unlike A/B testing, which focuses on testing one version against another, MVT involves creating numerous variant pages where different elements, such as headlines, images, buttons, and text) are altered. This A/B testing type is more complex and data-intensive as compared to the previous one.
3. Multi-page testing
Multi-page testing plays around with specific elements, such as the call-to-action button, and analyzes their impact across several pages within a user journey. It comes in handy when users want to understand how modifications to a consistent element affect user interactions and conversions throughout the entire funnel.
Role of A/B testing in marketing
Let’s understand the role of A/B testing in marketing and find out what difference it can make along the way:
- A major role of A/B testing is to provide undeniable evidence based on the data to make marketing or branding decisions. The process enhances user experience and optimizes marketing strategies. For instance, businesses can test different headlines, images, call-to-action buttons, or overall layouts to see which elements resonate most with their audience.
- 58% of companies use A/B testing for optimizing their conversion, whereas 35% of companies plan to use A/B testing for conversion optimization. Furthermore, 60% of the brands believe A/B testing is crucial to conversion optimization.
- One of the important roles of A/B testing in digital marketing is risk mitigation. Before implementing broad changes across an entire user base, companies can test on a smaller scale to ensure the modifications will have the desired positive impact. This approach minimizes potential negative effects on user engagement and conversion rates.
- A/B testing also fosters continuous improvement on the website or application. By regularly conducting such tests, businesses can keep up with evolving user preferences and market trends, thereby maintaining a competitive edge. This iterative process helps in fine-tuning engagement strategies on the website or app to incrementally boost performance over time.
- It’s crucial for personalizing user experiences. By analyzing which versions work best for different audience segments, marketers and conversion experts can tailor their content and offerings to meet specific needs and preferences, resulting in a better response from the target audience.
Benefits of A/B testing
A/B testing strategy has been around for years. There are numerous benefits of applying the A/B testing strategy that have helped brands and marketers increase attention and sales over the years. Here are the six of many benefits of A/B testing:
1. Get more user engagement
User engagement means how long users stick around when they visit a website or open an app. The longer the users stay, the higher the chances of sales. One of the benefits of A/B testing is that it can significantly improve the user engagement of a company.
A/B testing ensures that the business gets to choose the better versions of the website or app layout, color scheme, CTA color and text, landing page copy, and other elements.
2. Skyrocket conversion rate
Marketers and conversion experts always A/B test different sections of the website or landing page. Their ultimate goal is to increase the conversion rate of the business. Therefore, they make all necessary changes to test things out until they find the best combination.
The website or app elements that play a vital role in improving the conversion rate are call-to-action, website copy, headlines, colors, fonts, layout/design, etc. Undoubtedly, A/B testing is crucial to increasing conversion rates regardless of the industry.
3. Decline in the bounce rate
Bounce rate is the percentage of visitors that quickly leave the website or page without taking any noticeable action on the platform. No wonder digital marketers strive to reduce the bounce rates of their sales pages at any cost. Therefore, they tweak all sorts of things, for instance, the sales page design, layout colors, website fonts, CTA text, etc.
The purpose is to stop people from bouncing off the site without engaging with the site or app. A/B testing helps them figure out which combination of CTAs, colors, page designs, and website copy performs better than the others.
4. Low cart abandonment
Cart abandonment is a pain point for many e-commerce businesses and online retailers. Businesses use different engagement and remarketing tactics to reduce cart abandonment.
One of the perks of A/B testing is that it could impact the conversion process and eventually reduce cart abandonment. Businesses can A/B test the pricing model, UI/UX, CTA buttons, color scheme, and website copy just to see how this experiment works out for them.

Do’s When Running an A/B Test
Here we go:
- Define clear goals: Establish specific, measurable objectives before starting the A/B test to ensure meaningful results and start on the right foot.
- Segment your audience: Properly segment your audience to ensure that the test groups are representative and comparable.
- Run tests simultaneously: Conduct the tests at the same time to avoid seasonal or time-based biases. Otherwise, the results might not be accurate.
- Use sufficient sample size: Ensure your sample size is large enough to yield statistically significant results. No one wants to make their A/B look irrelevant.
- Test one variable at a time: Focus on a single element (e.g., headline, CTA) to accurately attribute changes in performance. It will also help you portray the results more clearly.
Don’ts of running an A/B Test
- Changing test parameters halfway through: Avoid altering the test setup or criteria once the test has started to maintain integrity. Any alteration, delay, or pause during the process might ruin the gist of the A/B test.
- Ignore the importance of randomization: Ensure random assignment of participants to eliminate selection bias. Ignoring randomization would be a huge mistake.
- Relying on short-term data: Avoid making decisions based on data collected over too short a period; let the test run its course.
- Testing multiple variables simultaneously: Testing several changes at once makes it difficult to determine which one caused the effect.
- Overlooking external factors: Consider external influences like holidays or market trends that might skew results.
