What is Multivariate Testing (MVT)?

Multivariate Testing, commonly known as MVT, is an advanced method used to test multiple variables on a website simultaneously to determine the best combination for improving conversion rates.

Unlike simple A/B testing where only one element is changed at a time, MVT allows for a more detailed analysis by changing several elements and observing how they interact with each other. 

This technique helps in understanding which variations of a webpage elements - such as images, text, or layout - work best together in converting visitors into customers. Businesses use MVT to make informed decisions about their website design and content, aiming to optimize the user experience and achieve better performance outcomes.

What are Multivariate Tests?

Multivariate (MVT) tests allow for the testing of multiple variables on a web page to determine the best combination for a desired outcome. These tests focus on identifying which variations perform the best in improving website effectiveness.

For instance, if a business wants to increase sales on an online store, it might change the layout, color, and text of the product pages. Traffic to these pages is divided among the different variations created during the test. This method provides a clear understanding of how different elements interact with each other and influence user behavior.

The scope of MVT extends beyond simple A/B testing, wherein only one variable is changed at a time. With MVT, they can explore numerous combinations of changes all at once. This approach helps businesses make informed decisions about their web design and content.

Difference Between MVT and A/B Testing

Multivariate Testing and A/B Testing are both used to optimize web pages by experimenting with different elements. They differ mainly in the way they handle variables and the complexity of the tests.

Multivariate Testing examines the effect of multiple variables changed simultaneously and how they interact with each other. It's used when a business wants to understand the relationship between various elements on a page.

A/B Testing, on the other hand, compares a control with a single variable change at a time, providing a clearer picture of the effect of that specific change. Let’s compare the main differences between these two testing methods:


Multivariate Testing (MVT)

A/B Testing

Variables Tested

Multiple variables changed at once

One variable changed at a time


High, due to various combinations

Lower, straightforward comparison


Understand how multiple changes interact

Understand the impact of a single change

Test Design

Requires a full factorial design to test combinations

Simple design with two versions: control and variation

Traffic Requirements

Higher traffic needed due to more variations

Less traffic can be sufficient for valid results

Result Analysis

More complex due to multiple factors

Why Need Multivariate Testing?

Multivariate Testing allows businesses to make data-driven decisions. By changing and testing multiple webpage variables at once, companies determine which combination maximizes user engagement or conversions.

The method differs from A/B testing, which compares just two versions of a webpage. MVT, instead, analyzes the effect of various element combinations, providing a better understanding of how they interact.

MVT testing requires a systematic approach due to the complexity of its variables. Each variation can affect user behavior differently, and knowing these outcomes helps optimize webpages effectively.

Planning an MVT Campaign

A well-structured MVT campaign begins by clearly defining what a business looks to achieve, determining how to measure success, and deciding which elements should be tested.

Setting Objectives

Objectives for an MVT campaign should be specific and measurable. They must align with overarching business goals such as improving the conversion rate or increasing user engagement. For example, you may strive to increase the sign-up rate for a newsletter or enhance the checkout process to boost sales.

Identifying Key Performance Indicators

Choosing the right Key Performance Indicators (KPIs) sets the foundation to evaluate the effectiveness of an MVT campaign accurately. Common KPIs may include conversion rates, click-through rates, or time spent on site.

These indicators should reflect the campaign objectives and enable a clear assessment of whether the changes positively impact user behavior.

Selecting Variables for Testing

The selection of variables for testing is important to the success of an MVT campaign. Variables could include different headlines, images, button colors, or calls to action. The choices should be informed by previous analysis or qualitative feedback, aiming to uncover actionable insights into which variations positively affect user interactions.

Data Collection and Analysis

MVT relies on tracking data and detailed analysis to make the best business decisions. Understanding the impact of different variables on user behavior is at the core of MVT.

Data Tracking

Data tracking in MVT involves monitoring user interactions with various page elements. Systems to collect user actions, such as clicks and time spent on a page, store and organize this information for review. Tag management solutions can facilitate this by ensuring consistent data capture across testing variations.

Statistical Significance

To determine the reliability of multivariate test results, one calculates the statistical significance. This measure indicates whether observed differences between page variations might be due to chance. A higher significance level suggests that results are likely reflective of actual user preferences, rather than random variation.

Analyzing Test Results

Effective analysis involves examining the performance of each combination against predetermined goals, such as an increase in sales or engagement rates.

Multivariate testing platforms generally provide a robust toolset that uncovers the interaction effects between tested page elements, revealing which combinations work best. Data management strategies pair with these platforms to sort through and interpret the layers of data produced by MVT.

Interpreting Test Outcomes

After running a multivariate test, you have to look at the data to see which changes made a difference. It's important to identify trends and understand how users interact with different elements.

Result Patterns

Patterns in the results indicate which element combinations improve performance. For example, if a webpage has been modified several times during testing, consistent improvements in user engagement or sales with particular variations can be considered a positive outcome.

Analysts create heat maps or click maps to visually represent user interactions, which can reveal strong performers and underachievers. Results should be segmented by different criteria, such as the type of audience, to gain more detailed insights into specific user groups.

Tables are an effective way to display complex data simply:

Best Practices in MVT

Adopting best practices in Multivariate Testing can significantly enhance the effectiveness of testing various elements on a digital platform. These practices help in understanding how different variables interact and their collective impact on user behavior.

Careful Approach

A well-defined strategy is imperative for successful MVT. It begins with setting clear objectives and identifying the elements to test - such as headlines, images, and calls to action. You should prioritize which elements could have the most impact and focus on those. 

It's advisable to determine specific goals or metrics for the test's success. This includes choosing one or two Key Performance Indicators (KPIs) that align with overall objectives.

Iterative Testing

MVT should be an ongoing process rather than a one-off experiment. Once the initial testing phase is complete, analyze the results and apply the insights to the next set of tests.

This iterative approach allows one to refine elements based on actual user data. Continuous testing can lead to incremental improvements, which often compound to generate significant enhancements over time.

Avoiding Common Pitfalls

To avoid potential obstacles, testers must avoid common mistakes such as testing too many elements at once, which can lead to inconclusive results. They should also ensure that their sample size is large enough to achieve statistical significance, enabling them to make data-driven decisions.

It’s important to recognize and avoid confirmation bias, where one might favor data that supports a preconceived notion. Lastly, delivering a consistent user experience across all variants is crucial to maintaining the integrity of the test.
