What is a heuristic evaluation

A heuristic evaluation is a method for identifying design problems in a user interface. In the case of an online store, a heuristic evaluation is performed to assess its usability and accessibility.  Often, the process is accompanied with guidelines (any set of heuristics) that help measure usability and facilitate the reporting of issues.

Jakob Nielsen’s 10 usability heuristics are recommended guidelines for performing a heuristic evaluation for any ecommerce website. This is mainly because of its comprehensive nature, based on an understanding of human behavior, psychology, and information processing.

In this post, we’re going to explore its benefits of a heuristic evaluation, how to perform it, challenges, and practical tips for implementation. Whether you’re an ecommerce business looking to improve your online store’s usability, or a UX enthusiast eager to learn more about the specific use of a heuristic evaluation in ecommerce, this article is designed to provide you with the essential knowledge and insights to get started.

Benefits of a heuristic evaluation in ecommerce

Usability issues are far more common and its impact is more far-reaching than most businesses realize. Heuristic evaluation is one of the most effective methods that can be applied to detect and resolve issues such as unclear or complex navigation, cluttered layouts, or bad error handling. Let’s look at specific examples of how a heuristic evaluation can be beneficial for your ecommerce.

Increased conversions

Heuristic evaluation can help ecommerce businesses increase conversions by identifying and addressing usability issues that may be preventing customers from completing transactions. For example, a checkout button that is not clearly visible can make it difficult for customers to find and complete their purchases, leading to a high bounce rate.  By resolving such issues, businesses can increase the likelihood of customers to take action and complete their purchases.

Cost savings

Another benefit of a heuristic evaluation is the cost savings it can provide. By identifying and addressing usability issues early on, ecommerce businesses can avoid costly rework or redesign. This is especially important because the negative impact of usability issues tend to amplify as an ecommerce platform scales up. A heuristic evaluation helps businesses save time and money, especially when done on a frequent basis.

Improved accessibility

Heuristic evaluation can also help ecommerce businesses improve accessibility by identifying and addressing usability issues that may be preventing customers with disabilities from using their websites. This not only ensures that their websites comply with accessibility guidelines, but also widens their customer demographic.

Enhanced Search Engine Optimization (SEO)

Heuristic evaluation can also help ecommerce businesses enhance their SEO by identifying and addressing usability issues that may be affecting their search engine rankings. A notable example is a website that has categories and subcategories that are difficult to navigate. Organizing categories and subcategories in a logical manner, as well as using clear and descriptive category names, are recommendations that can be guided through a properly executed heuristic evaluation. 

How do you perform a heuristic evaluation

In this section, we will explore the steps involved in performing a heuristic evaluation in ecommerce.

Step 1: Determine the scope and stakeholder requirements

The first step is to agree on the scope of the heuristic evaluation. Is it budgeted for the entire ecommerce website, or is there a business need to focus on one aspect of the user experience? The narrower the scope, the easier and more detailed the evaluation will be. 

Tip: It is usually recommended to keep the scope narrow or to break it down into several mini-projects, especially if you have a large, complex platform. There are a number of ways that you can break down the heuristic evaluation of an ecommerce website:

  • By task (e.g. search, navigation, registration)
  • By section (homepage, product listing page, account page)
  • By user group (if you have a diverse customer base)
  • By device type (desktop, tablet, mobile)

Step 2: Prepare resources

The second step is to determine how the findings and results are documented and compiled. If you do not come up with an efficient strategy for this, the subsequent evaluation will be haphazard and you may find difficulty extracting insights from the results.

Here are some options for documenting:

  • Spreadsheet (Excel or Google): Create a sheet for each evaluator to capture their observations for each corresponding heuristic. List guidelines and questions in these sheets so that evaluators know what to look for, and have two separate columns for issues and recommendations.
  • A digital whiteboard: Digital workspaces like Miro allow evaluators freedom to visualize issues that they encounter. You can include screenshots of your ecommerce pages and have evaluators place sticky notes of their analysis and recommendations.

Tip: Whichever tool your team uses for documenting, they should not be able to see each other’s evaluations until their own evaluation is complete. The reason being that you want them to capture independent observations that are not influenced by one another.

Step 3: Recruiting participants

The next step is to recruit participants who will test the website. This can include customers, potential customers, or even employees who have used the website. The goal is to recruit a diverse group of participants who will provide a range of perspectives on the website’s usability.

Tip: For teams and participants performing their first heuristic evaluation, they will need training on the usability heuristics used. Provide examples so that they will feel comfortable applying the heuristics to practical scenarios.

Step 4: Evaluation

With the people, tools and resources in place, the heuristic evaluation itself is ready to begin. During this step, it is recommended for evaluators to first get familiar with the ecommerce website and the task, from the point of view of a user. Once they are comfortable and have a good understanding of the task scope, they can start to look for issues.

Tip: As part of the evaluation process, evaluators should rate the usability issues they encountered. This can be done by rating usability issues on a scale of 1 to 5, with 1 being the most critical and 5 being the least critical.

Step 5: Consolidate issues and analyze results

Once the evaluation is complete, a team discussion should take place to analyze the results. This involves identifying the most common usability issues, prioritizing them based on severity and business impact, and developing both a short-term and long-term plan to address them. This may involve changes to the website’s design, content, or functionality.

Tip: Take this opportunity to review how well the evaluation process worked. What could be improved? What should the team prioritize in the next heuristic evaluation?

Challenges of a heuristic evaluation

While heuristic evaluations offer numerous benefits for ecommerce websites, there are also some challenges to consider when conducting this type of usability assessment. Understanding these challenges can help ecommerce teams navigate the process more effectively and get the most value out of their heuristic evaluation.

Choosing the right heuristics

One of the primary challenges is selecting the appropriate set of heuristics to evaluate the ecommerce website. The heuristics need to be tailored to the specific features and user needs of the ecommerce context, rather than relying on generic usability principles. Choosing the wrong set of heuristics can lead to missing critical usability issues.

Evaluator expertise

The effectiveness of a heuristic evaluation is heavily dependent on the expertise and experience of the evaluators. Evaluators need to have a strong understanding of both usability principles and the specific requirements of ecommerce user experiences. Less experienced evaluators may overlook important issues or misinterpret the severity of problems.

Scope and focus

Ecommerce websites can be large and complex, with many different pages, features, and user flows. Determining the appropriate scope and focus for the heuristic evaluation is crucial to ensure the process is manageable and provides meaningful insights. Evaluating the entire website at once may be overwhelming, while being too narrow in scope could miss critical usability problems.

Subjectivity and bias

Heuristic evaluations inherently involve a degree of subjectivity, as evaluators may interpret the same usability issues differently. Evaluator bias, based on personal preferences or experiences, can also influence the findings. Establishing clear evaluation criteria and having a diverse set of evaluators can help mitigate these challenges.

Integrating with other UX methods

While heuristic evaluations can provide valuable insights, they should not be used in isolation. Integrating heuristic evaluations with other user experience research methods, such as usability testing, can provide a more comprehensive understanding of the ecommerce website’s usability and user experience.
