Welcome to the fifth installment in our six-part blog series where we discuss the CRO tools and techniques essential to success in the Research stage of your CRO programme. (If you’ve missed out on the previous blogs in this series, see the 5 Types of CRO Research Tools, Surveys, Maps, and A/B Tests.) This series is based on our infographic, ‘The Periodic Table of CRO Success Factors’. This week we’re delving into an important – but often misunderstood – CRO technique: heuristics.
Before we get started, let’s look at what heuristics is – and isn’t
Derived from the Ancient Greek word for ‘find’ or ‘discover’, Wikipedia defines heuristics as “any approach to problem solving, learning, or discovery that employs a practical method not guaranteed to be optimal or perfect, but sufficient for the immediate goals.”
This broad explanation has left much room for misinterpretation of the term, and whilst heuristics is not a data-driven approach, it isn’t based on subjective opinions either. In the context of CRO optimisation, heuristics is best thought of as a process whereby a website is evaluated using a framework of pre-determined criteria.
The outcome of your heuristic evaluation is only as good as your framework
To get the most out of your heuristic review, you need to provide your reviewers with criteria they’ll use to analyse your site. This ensures that findings aren’t marred by bias, subjectivity or a reviewer’s “tunnel vision”. In the context of CRO, the most frequently-used elements of a heuristic framework are: motivation, value proposition, relevance, incentive, distractions, and anxiety and friction.
These six criteria seek to address every aspect of the purchasing process, and the behaviour that facilitates (or hinders) it
Your customers are motivated to buy by an inherent need – whether consciously or subconsciously. Since the end goal of the CRO process is to match this behaviour as closely as possible, your heuristic evaluation needs to begin here. Focus on your visitors’ motivations and needs when evaluating the site - you should have already collected survey data, so have this information at the ready.
A compelling and convincing value proposition persuades customers to buy from you as opposed to clicking away to one of your competitors. As mentioned in the book I co-authored with Johann Van Tonder, COO of AWA, ‘E-commerce Website Optimization’, this concept is vital in the overall CRO process, and your review team should spend time answering these questions:
- “Is the value proposition easy to understand?”
- “Is it conveyed clearly?”
- “How does it fare compared to the expectations of our customers”
- “How does it fare against the value propositions of our competitors?” and crucially,
- “Does it convey how our product or service will fulfill the needs of our customers?” (We discuss this heuristic principle in more detail in the book mentioned above.)
This heuristic is used to determine whether your brand’s message is in line with your specific target market and their associated buying behaviour, challenges and needs. Your review team needs to determine whether these key messages are consistent, clear and convincing throughout their time on your site.
Your review team needs to establish the ways your site, or aspects of it, are incentivising conversion. They need to answer questions like: How does your site incentivise purchasing behaviour? What are the aspects used to do this? Is an incentive, like a discount code, strong enough to convert? Can these incentives be communicated more clearly?, and so on.
Getting – and keeping – the attention of your customers long enough for them to convert is crucial. In a world where distractions abound, you need to make sure that no site elements are unwittingly distracting visitors from completing a purchase. As such, evaluators need to identify any site elements that are drawing attention away from conversion.
Anxiety and Frictions
As pointed out in the book, the heuristic principles anxiety and friction “are negative forces that get in the way of conversions, even when a user is highly motivated and everything else falls in place.” There’s a subtle difference between the two: while anxiety is an intangible emotion, existing solely in the mind of a visitor, frictions are site features that make the purchasing process difficult to complete.
To get the most out of your heuristics review, it’s important to keep the following guidelines in mind
The ideal number of reviewers is between three and five. If you’re short on staff, ensure you use at least two people to prevent subjective bias and ensure all conversion issues are identified.
Encourage your team to collaborate: this saves you time and avoids duplicate reviews. It also allows for the objective discussion of issues and the most prudent way to address them.
Use a framework that contains the six principles outlined above. As we mention in our book, without these fixed criteria, your heuristic evaluation is “simply an “expert review”, which generally only scratches the surface compared with a systematic heuristic evaluation.”
Before your group evaluation begins, issue reviewers with a comprehensive brief
This should contain the following:
- The URL of the site, or of the individual pages that need review
- Target market personas
- A list of the heuristic principles mentioned above
- Buying scenarios as dictated by your personas
- Specific tasks each evaluator needs to complete
- The device they need to use
Heuristics form a crucial CRO technique that will help you to further optimise your site on a granular level. That said, successful CRO is a continual process that requires a scientific approach.
