How A-B Testing Works And How Can It Help Your Small Business?


How A-B Testing Works -- And How It Can Help Your Small Business

Wondering how A-B testing works in a small business?  A-B testing is a great way to compare online marketing strategies or tools to see which one is working better. It’s a cost effective way of pitting everything from web pages to email campaigns against each other so you get the best ROI. Using this method, you’ll get the numbers and statistics to see what needs to be changed out, tweaked or left alone.

Here’s How A-B Testing Works in a Small Business

Let’s say you’re putting together a website for your small widget business. You’ve sourced a few different designers and got two excellent mock-ups. Your torn between the two but need to make a choice.

A-B testing allows you to keep your emotions in check and use empirical data to make a decision. You’ll need to start by splitting the website traffic between the two candidates.

Then, once the data starts flowing in, you can start to see which website designer’s work is performing best. With this example, you’ll also need to herd the numbers toward certain corrals that matter to you. For example, you might use metrics like the conversion rate and the bounce rate of both designers before making a final decision.

The metrics that you use often depend on what you’re testing. However, there are a few common ones.

Bounce Rate

In a nutshell, making a good first impression is what this metric is all about. That’s why you need to include it. If people are looking at your landing page(s) and leaving right away, it’s a big red flag you need to look at.

Exit Rates

These tell you the story of the visitors that get past the landing page but still decide to leave.  If visitors are dropping off at a certain page, you know where to start work.

Engagement Metrics

These are averages that help to bring everything into focus. Taking a look at the averages can show you which pages need to be tweaked.

Like anything else you use for small business marketing, there are some do’s and don’ts when it comes to A-B testing.

A Few A-B Testing Don’ts

Don’t test one item and then the other. For example, if you’ve got two email campaigns to choose from, testing one in September and one in October will skewer the results. Running both at the same time ensures the subjects or traffic is consistent.

Don’t be in a rush. You’ll be getting lots of information once you start one of these tests. The trick is not to end the experiment too early. Using only a few visitors over a short period of time wont give you enough data to make the right choices. Here’s a calculator that will help you decide how long the test should be.

A Few A-B Testing Dos

There are some best practices you should follow.

Be consistent. If you’re testing a Call To Action across several pages, it should designed the same across them all. Changing the design from page to page will skewer the data.

De several tests. The chances are you’ll make a few mistakes on your first A-B test. To get a template you can use, you’ll need to work on refining the techniques you use. For example, you can test several variants at once or even design your own approach. Get a few good ideas here.

Maximizing A-B Testing Success for Small Businesses

A-B testing, also known as split testing, is a powerful tool for optimizing your online marketing strategies and improving your ROI. To ensure you make the most of this method, consider the following tips:

  • Clearly Define Your Objectives
    • Before starting an A-B test, establish clear and specific objectives. What do you want to achieve with the test? Define your key performance indicators (KPIs), such as conversion rate, click-through rate, or bounce rate.
  • Test One Variable at a Time
    • To obtain accurate results, focus on testing one variable at a time. Whether it’s the design of a landing page, the subject line of an email, or the placement of a call-to-action (CTA) button, isolating variables ensures you know exactly what’s causing changes in performance.
  • Use Statistical Significance
    • Ensure that your test results are statistically significant before drawing conclusions. Running tests with insufficient data can lead to inaccurate decisions. Various online tools and calculators can help you determine the sample size needed for valid results.
  • Segment Your Audience
    • Different audience segments may respond differently to your variations. Consider segmenting your audience based on demographics, behaviors, or preferences. Tailor A-B tests to specific segments to better understand what works for each group.
  • Regularly Monitor and Analyze Data
    • Don’t wait until the end of a test to check results. Regularly monitor the data and make adjustments as needed. If one variation is significantly outperforming the other early in the test, it may be worth ending the test early.
  • Ensure Consistency
    • Maintain consistency in design and messaging across all test variants. Changing other elements while testing one variable can lead to skewed results. Keep everything else constant to accurately attribute changes to the tested variable.
  • Implement Continuous Testing
    • A-B testing is not a one-time effort. Continuously test and refine your marketing strategies. As you gather insights from previous tests, apply them to future campaigns for ongoing improvement.
  • Document and Learn
    • Keep a detailed record of your A-B tests, including the hypotheses, variations, and outcomes. Documenting your tests allows you to learn from past experiments and avoid repeating mistakes.
  • Consider Mobile Responsiveness
    • With the increasing use of mobile devices, ensure that your A-B tests account for mobile responsiveness. Test how variations perform on different screen sizes and devices to cater to your mobile audience effectively.
  • Seek Professional Guidance
    • If you’re new to A-B testing or want to maximize its potential, consider consulting with professionals or agencies experienced in data-driven marketing. They can provide valuable insights and guidance to help you achieve your marketing goals.

Designing Effective A-B Tests

Designing effective A-B tests is crucial for obtaining reliable data to inform your marketing decisions. A well-designed test ensures that the differences in performance between two variations can be attributed to the changes made, rather than external factors. Here’s how to design an effective A-B test:

  • Define Clear Objectives: Before starting, determine what you want to achieve with your A-B test. Are you looking to improve the conversion rate, reduce bounce rates, or enhance user engagement on a specific page? Having a clear objective will guide your test design and help you measure success.
  • Identify Variables: Select the element(s) you want to test, such as headlines, call-to-action buttons, images, or page layouts. It’s crucial to test one variable at a time to clearly attribute any differences in performance to that specific change.
  • Create Variations: Develop two versions of your asset: the control version (A), which is the current version, and the variation (B), which includes the change you’re testing. Ensure that the variations differ only in the variable being tested.
  • Select Your Audience: Decide on the segment of your audience that will participate in the test. This could be all visitors to a particular page or a specific user segment. Consider randomizing the assignment of visitors to each variation to avoid selection bias.
  • Determine Sample Size and Duration: Use statistical tools to calculate the sample size needed to achieve statistically significant results. Also, decide on the duration of your test, considering factors like your website’s traffic volume and the expected difference in performance between variations.
  • Choose the Right Tools: Select A-B testing software that fits your needs and integrates well with your website’s technology stack. Many tools offer features like audience segmentation, real-time data analysis, and integration with analytics platforms.
  • Launch and Monitor: After setting up your test, monitor it closely to ensure it’s running as expected. Be prepared to make adjustments if technical issues arise.

By following these steps, you can design A-B tests that provide valuable insights into how different elements impact user behavior and conversion rates.

Once your A-B test is complete, analyzing the results accurately is essential to make data-driven decisions. Here’s how to approach the analysis:

  • Review Test Objectives: Revisit your initial objectives to ensure your analysis focuses on the right metrics.
  • Check Statistical Significance: Use statistical analysis to determine if the observed differences between the control and variation are statistically significant. This usually involves calculating the p-value and comparing it to a predefined significance level (often 0.05).
  • Calculate Effect Size: Beyond statistical significance, assess the effect size, which measures the magnitude of the difference between variations. This helps you understand the practical significance of the test results.
  • Analyze Secondary Metrics: Look at how the test impacted secondary metrics that weren’t your primary focus. This can provide additional insights into the effect of the tested changes.
  • Segment Results: Break down the results by audience segments, such as new vs. returning visitors or mobile vs. desktop users, to uncover more nuanced insights.
  • Draw Conclusions and Plan Next Steps: Based on the analysis, decide whether to implement the tested changes, run additional tests, or explore alternative hypotheses.
  • Document and Share Findings: Record the test setup, results, and conclusions for future reference. Share the insights with relevant stakeholders to inform broader marketing strategies.

Future Trends in A-B Testing

The field of A-B testing is rapidly evolving, driven by advances in technology and shifts in consumer behavior. Here are some future trends to watch:
