Why businesses need developers to run effective A/B tests

A/B testing can be a complex process that requires technical expertise, time and resources to run effectively

Introduction

As a business owner or marketer, A/B testing is an essential tool to optimise your website and improve your conversion rates. It allows you to test different variations of your website or landing page to determine which design, messaging, or layout resonates better with your target audience. However, A/B testing can be a complex process that requires technical expertise, time and resources to run effectively.

In-house A/B testing challenges

Many businesses that are new to A/B testing often face common challenges, such as selecting the right testing tool, creating meaningful hypotheses, designing effective variations and analysing the results.

One of the most significant challenges that businesses face when running A/B testing experiments is the technical aspect. Not all business owners or marketers have the coding skills or technical knowledge required to set up and run A/B tests correctly. Complex A/B testing experiments may require more advanced technical knowledge, making it difficult for businesses without dedicated in-house developers to implement.

There is a big risk that inexperienced users may set up and implement their A/B tests incorrectly, leading to inaccurate or unreliable data, which can ultimately impact the effectiveness of their website optimisation efforts.

Leveraging developer expertise for effective A/B testing

A developer can bring a wealth of technical expertise and experience to your A/B testing efforts. They can help you select the right testing tool for your needs, create effective variations, set up and implement your tests, and some developers may even be able to help you analyse the results to identify actionable insights.

Additionally, a developer can help ensure that your A/B tests are properly integrated with your website or landing page, minimising any potential negative impacts on user experience or website performance.

Let me bring it to life for you
Here are some examples of what a developer can bring to the table when running A/B tests, that a non-developer may struggle with:

Customisation
Developers can create custom variations that are not available in an A/B testing tools' standard library. For instance, creating a unique design, colour scheme, or layout, that aligns better with the website's branding or user preferences. An example of such a customisation could be creating a unique variation that displays a different CTA (Call-To-Action) button on a websites product page.

Advanced tracking
Developers can help set up advanced tracking tools to track specific user interactions on your website. For instance, creating custom event tracking using Google Analytics, allowing you to track user behaviour, such as clicks, scrolls, and form submissions. This level of tracking is beyond the capability of most A/B testing tools.

Technical integration
Developers can help integrate A/B testing tools with the websites backend or third-party tools, such as CRM systems, email marketing platforms, or eCommerce platforms. For instance, integrating with Shopify, allowing you to run tests on product pages, shopping carts, or checkout pages. This integration requires technical knowledge beyond the expertise of most non-developers.

Complex experiment setups
Developers can help set up and run complex A/B tests that require more advanced technical knowledge. For instance, a test to compare two different algorithms for personalised content recommendations on a website. Such tests involve coding a complex algorithm, testing it against another algorithm, and analysing the results to determine which one performs better. This type of experiment requires a high level of technical expertise that most non-developers do not possess.

Shameless plug

A/B testing is a crucial tool for optimising your website and improving your conversion rates. However, it can be challenging to implement and manage, especially for businesses without dedicated in-house developers.

By working with a technical agency, such as Daydot, you can access the expertise and resources you need to run effective A/B tests and achieve your website optimisation goals.
