When it comes to conversions, knowledge is power.
Knowing exactly what your audience likes and what they'll be interested in is what helps you connect with them. The secret to more conversions is creating a website that speaks directly to your visitors, anticipates their needs, and guides them effortlessly towards clicking that button or filling out that form.
CRO testing helps you figure out just that. It tells you exactly what makes your audiences tick. By showing your visitors different versions of your webpages, CRO testing reveals exactly what makes them perform the actions you want them to.
In this article, we'll explore everything you need to know about CRO testing. We'll cover everything from the different types of tests you can run to the common challenges you might face and how automated testing with AI can make the entire process quicker and easier.
Key Takeaways
What is CRO testing?
CRO testing or Conversion Rate Optimization Tests are structured experiments you run on your website to figure out how to get more visitors to do what you want them to do, whether that's buying a product, filling out a form, or downloading a newsletter. You do this by comparing different versions of your website to see which one your audience connects with the best.
A CRO test isn't just about randomly tweaking things and hoping for results. It is a controlled experiment. You start with a hypothesis about what might be hindering conversions. Then, you create a variation of your webpage with the proposed change and show it to your audience while another segment sees the original version. You then see which version performs better.
The most common type of CRO test is the A/B test, where you compare two versions of a page. But there are other, more complex tests, like multivariate testing, that allow you to experiment with multiple elements at once.
Ultimately, a CRO test helps you understand user behavior. It reveals what resonates with your audience and what doesn't. This helps you make informed decisions about your website design, content, and overall user experience.
Types of CRO testing
There are many types of CRO tests you can choose from. To identify which tests you need to use, you need to first understand the purpose of each test and how it works.
1. A/A Test
The first type of test is an A/A test which is basically a control experiment. You test a page against an identical copy. It validates that your analytics, tracking, and A/B testing platform are functioning correctly. It also helps rule out any "novelty effect", where a change, any change, might temporarily influence user behavior.
For example, before launching a major redesign, you run an A/A test on your current landing page to ensure all tracking and conversion goals are accurately recorded. This prevents skewed results when you later test the new design against the old.
2. A/B Test (Split Test)
The classic A/B test is the most popular test for CRO. Here you compare two versions of a webpage: the original (control) and a modified version (variation). You change a single element in the variation, this could be a headline, button color, or image to isolate its impact on conversions. However, you can only test one variable at a time, which can slow down your testing velocity.
Imagine you suspect your call-to-action button's color is hindering conversions. In this case, you create a variation with a different color and run an A/B test to see which performs better.
3. A/B/n Test
A/B/n testing takes A/B testing a step further by comparing multiple variations of a page element simultaneously. Instead of just A and B, you might have A, B, C, and even D. This can help you quickly identify the best performing option from a wider range of choices, helping explain interactional relationships between variables. However, with more variations, your sample size per variation decreases and there is a higher chance of false positives.
For example, if you want to test three different headlines for your product page. An A/B/n test allows you to run all three variations against the original simultaneously. This can quickly tell you which one works best for your audience.
4. Multivariate Testing (MVT)
Multivariate testing (MVT) is like A/B/n but it lets you test multiple elements and their combinations on a page at the same time. This would look like changing the headline, image, and call-to-action button simultaneously, each with multiple variations. MVT helps you understand the interplay between these elements and identify the optimal combination. It saves time by testing multiple combinations concurrently.
5. Multi-Armed Bandit (MAB)
The last test type is the Multi-armed bandit testing which starts like an A/B/n test, but the traffic allocation between variations changes automatically during the test. The algorithm favors the better-performing variations and shifts more traffic to them while reducing traffic to underperforming ones.
This test uses an "explore and exploit" strategy to help you quickly converge on the best option. It's faster and more efficient than traditional A/B testing, especially when focusing on a single metric.
Common CRO testing challenges and how to avoid them?
CRO testing is essential for any business looking to improve its website and boost conversions. However, it's not always easy to get it right. There are several common challenges that can trip you up along the way. Let's explore these challenges and discuss practical strategies to overcome them.
1. Testing Without a Plan
It's easy to get excited about CRO testing and jump right in, but without a clear plan, you're likely to end up with confusing results and wasted resources. Without a plan, your testing efforts can become scattered and ineffective. You might end up testing random elements without a clear objective, leading to minimal impact on your bottom line.
How to avoid:
2. One-off testing
One-off testing refers to the practice of conducting a single test in isolation and then stopping, rather than testing consistently to get the full picture. One-off testing can provide limited insights because it doesn't consider the interconnectedness of different elements on your website. Changing one element can have unintended consequences on others, and you might miss out on opportunities to optimize the overall user experience if you're only focused on individual components.
3. Not knowing your KPIs
Key Performance Indicators (KPIs) are the metrics that measure the success of your CRO efforts. Without clearly defined KPIs, you might make changes to your website, but how will you know if they're actually driving the results you want?
Without KPIs, you might focus on the wrong metrics or make changes that don't contribute to your overall business goals. It can also be difficult to measure the success of your CRO efforts if you don't know what you're measuring.
4. Small sample size
Small sample sizes are more susceptible to random fluctuations and outliers, which can skew your results and lead to inaccurate conclusions. You might mistakenly attribute a change in conversions to your test variation when it's actually due to chance or other external factors. What this means is that with unreliable results, you may end up implementing changes that don’t actually improve your CRO.
5. Not upholding testing timelines
It's tempting to end a test early when you see promising results, but patience is crucial in CRO testing. Prematurely ending a test can lead to inaccurate conclusions, missed opportunities, and ultimately, hinder your optimization efforts.
Early trends might not reflect the true impact of your test variation. Ending a test early can lead to false positives or negatives, where you mistakenly attribute a change in conversions to your variation when it's actually due to chance or other external factors.
How to conduct CRO testing (steps with examples)
Okay, as it might be clear by now, CRO testing is not just performing tests randomly. It's systematic, that helps you figure out what works. And just like any scientific method, there are steps to follow if you want to get reliable, meaningful results. Here's your guide to conducting CRO tests that deliver valuable insights and drive real improvements.
Step 1: Research
First things first. You want to conduct a test. Say you want to increase conversions by creating better CTA buttons or attract more engagement with catchier headlines. That’s great. But how do you know that this would actually work? Do you know for a fact that it is your CTA buttons that are hindering conversions?
This is where research comes in. It can help you answer questions like:
Research can take many forms:
Here’s how research would work:
Let's say you're an e-commerce business and you want to increase your add-to-cart rate. Through website analytics, you notice that a significant number of users are visiting your product pages but not adding items to their cart. You could then use heatmaps and session recordings to see how users are interacting with the product pages and identify any potential friction points.
You might discover that the "add to cart" button is not prominent enough, or that users are confused about product variations or shipping options. These insights would then inform your CRO test hypothesis and design.
Step 2: Design your CRO test
Now that you've done your research and have a solid understanding of the problem you're trying to solve, it's time to design your CRO test. This involves clearly defining your hypothesis, outlining your testing methodology, and determining your success metrics.
Hypothesis
A hypothesis is basically a statement you make about what you expect to happen in your test. It's an educated guess, based on your research, about how a particular change will impact user behavior and conversions.
Here's an easy formula to help you frame a hypothesis for your CRO test:
If [we make this change], then [this will happen], because [this is the reason based on our research].
For example:
If we change the color of the call-to-action button from green to red, then we will see an increase in click-through rates, because red is a more attention-grabbing color and our research suggests that users are currently overlooking the green button.
Remember that your hypothesis should always be specific, measurable, testable and data-driven.
Testing Methodology
Under testing methodology, you'd have to define the following factors:
Success Metrics
Clearly define the key performance indicators (KPIs) you'll be tracking to measure the success of your test. These might include:
Let's take inspiration from the ACT Fibernet case study. They wanted to expand their reach across India and increase customer acquisition through their Google search ads. In this case, their hypothesis would have sounded something like:
If we personalize the landing pages with city-specific content and offers, then we will see an increase in user engagement and conversions, because the content will be more relevant to each visitor's needs and interests, as indicated by our research on user preferences in different regions.
Now, using A/B tests powered by Fibr AI, they tested this hypothesis. The impact of personalization was evaluated based on KPIs such as:
Step 3: Build the test and variants
With your test designed, it's time to build the actual variations you'll be testing. For example, if you're testing a new call-to-action button, you'll need to create a variation of your webpage with the new button design. This might involve changing the button's color, size, text, or placement.
Make sure to test the new button on different devices and browsers to ensure it's visually appealing and functional across all platforms.
Now, creating many versions of a webpage can be tedious. Fibr AI's bulk creation tool makes it incredibly easy to create and implement different variations for your CRO tests. You don't need to be a coding whiz to experiment with different designs, layouts, and content. You can quickly generate and test multiple variations and start your testing.
Step 4: Run the test
Now it's time to launch your test. For this you’d have to set up your testing platform, configure your variations and monitor your tests to ensure everything is running smoothly. Here is what you need to set up:
Step 5: Analyse test data and make further changes
Once your test has run its course, it's time to analyze the data and draw conclusions. This involves interpreting your test results, identifying statistically significant differences, and determining the winning variation (if any).
Ensure your results are statistically significant before making any decisions. This means that the observed differences between your variations are likely due to real changes and not just random chance.
Also, don’t just rely on quantitative data. Use heatmaps, session recordings, and user feedback to understand why certain variations performed better than others.
