What’s the difference between CRO and UX and why does it matter for your business?

What Is Conversion Rate Optimisation (CRO)?

Conversion Rate Optimisation (CRO) is the process of improving the effectiveness of your website or landing page in turning visitors into customers, leads, or other valuable actions. In simpler terms, CRO is all about getting more from the visitors who are already on your website by optimising different elements to increase conversions.

CRO focuses on improving measurable outcomes such as:

  • Sales: For eCommerce sites, converting visitors into paying customers.
  • Leads: For service-based businesses, converting visitors into sign-ups, form submissions, or consultations.
  • Engagement: For content or SaaS businesses, increasing interactions like sign-ups, downloads, or subscriptions.

The goal of CRO is to systematically test and optimise your website’s elements, such as CTAs, form layouts, copy, and navigation, to increase the percentage of visitors who take the desired action.

Key Strategies for CRO:

  • A/B Testing: Testing different versions of a page to determine which performs better.
  • Persuasive Copy: Crafting compelling and action-oriented copy that drives visitors to act.
  • Clear CTAs: Ensuring calls to action are compelling, obvious, and lead users to a specific action.
  • Social Proof: Including testimonials, reviews, and case studies to build trust.
  • Simplified User Journeys: Minimising friction in the path to conversion by streamlining processes.

Real-World Example: Let’s take a look at ASOS, a leading UK fashion retailer. By implementing A/B testing on its product pages, ASOS increased its conversion rates by experimenting with different product descriptions and images. By aligning the website’s elements with customer preferences, ASOS boosted engagement and sales without needing to increase traffic.

What Is User Experience (UX)?

On the other hand, User Experience (UX) refers to the overall experience a user has when interacting with your website or product. It encompasses everything from the ease of navigation to the feel of the interface. UX design focuses on ensuring that users can easily achieve their goals in a seamless and enjoyable way. The aim is to enhance user satisfaction and create a positive perception of your brand.

UX includes:

  • Navigation: Ensuring that users can find what they are looking for without frustration.
  • Design & Layout: Creating aesthetically pleasing and functional layouts that provide a pleasant browsing experience.
  • Content Accessibility: Ensuring that your website content is readable, easy to understand, and accessible to all users.
  • Mobile Responsiveness: Making sure the site performs well on mobile devices, which is crucial in the UK market, where mobile internet usage continues to rise.

UX design aims to make the user’s journey as intuitive and pleasant as possible, reducing frustration and barriers that could lead to abandoned sessions.

Key Principles of UX Design:

  • Consistency: The design elements should be consistent across the site to avoid confusion.
  • User-Centricity: The design should focus on the needs and preferences of the target audience.
  • Clarity: Clear labels, understandable navigation, and intuitive layouts are all part of good UX design.
  • Speed: Pages should load quickly, reducing user frustration and bounce rates.

Real-World Example: Apple provides a stellar example of UX design. Its website is simple, intuitive, and easy to navigate, making it easy for users to find products, check specs, and complete purchases. The company focuses heavily on reducing friction in the user journey, from product selection to checkout.

Key Differences Between CRO and UX Design

Now that we have a clearer understanding of both CRO and UX, let’s explore the key differences between these two crucial concepts:

1. Focus and Objective
  • CRO: The main goal of CRO is to increase the conversion rate. It’s highly metrics-driven, focusing on turning a higher percentage of visitors into customers or leads. CRO typically uses data-driven methods like A/B testing, heatmaps, and analytics to identify which elements of a webpage are hindering conversions and optimising them for better results.
  • UX Design: UX is broader in scope. It focuses on improving the overall experience of the user, ensuring that the website is easy to use, visually appealing, and meets the needs of the user. While UX design can lead to improved conversions, its primary focus is on user satisfaction, usability, and accessibility.
2. Approach
  • CRO: CRO often takes a more tactical approach. It involves detailed testing, analysis, and fine-tuning of specific elements like CTAs, copy, or page layout. CRO seeks quick wins by identifying elements that can be improved to boost conversions directly.
  • UX Design: UX design is more strategic and long-term. It focuses on creating a user-friendly experience from start to finish, considering the entire user journey, from first interaction to post-purchase engagement. UX design aims to create an emotional connection between the user and the brand through positive experiences.
3. Methods
  • CRO: CRO typically uses quantitative methods like A/B testing, funnel analysis, and analytics to track conversions and user behaviour. It’s about testing specific hypotheses and finding which design elements resonate best with users.
  • UX Design: UX uses both qualitative and quantitative methods, including user research, usability testing, persona creation, and journey mapping. UX design places a strong emphasis on understanding the user’s needs, motivations, and pain points before creating solutions.
4. Success Metrics
  • CRO: The success of CRO is measured by conversion rates, or the percentage of visitors who complete a desired action. This could include form submissions, product purchases, or newsletter sign-ups.
  • UX Design: The success of UX is measured by user satisfaction, usability scores, task completion rates, and other qualitative metrics like Net Promoter Score (NPS) or customer feedback.

How CRO and UX Complement Each Other

Although CRO and UX may seem like two distinct disciplines, they are deeply interconnected and should work together harmoniously. A great user experience often leads to better conversion rates, while optimising for conversions often enhances the overall user experience.

Here’s how they complement each other:

  1. Improved Experience Leads to Higher Conversions: A seamless and intuitive UX design reduces friction in the user journey, leading to higher satisfaction and increased likelihood of conversion. If users have a smooth and enjoyable experience, they are more likely to convert.
  2. Optimisation for the User Journey: CRO focuses on optimising specific parts of the website to drive more conversions. However, these optimisations should align with UX best practices to ensure they don’t disrupt the user experience. For example, a well-designed CTA that leads to a clean, easy-to-navigate checkout page will increase conversions without frustrating the user.
  3. Testing and Feedback Loop: Both CRO and UX rely on data to improve performance. UX design involves user research and testing to understand user needs, while CRO uses A/B testing to optimise elements for conversions. These two areas can feed into each other, creating a continuous feedback loop that leads to incremental improvements in both user experience and conversion rates.

Why CRO and UX Matter for Your Business

If your business is looking to thrive in a competitive market—especially in the UK where digital expectations are high—getting both CRO and UX right is essential. Here’s why they matter:

  1. Increased Conversions and Revenue: A well-optimised landing page or website can significantly increase your conversion rates, turning more visitors into customers and ultimately increasing your revenue. By focusing on both CRO and UX, you create a user-friendly experience that encourages action.
  2. Customer Retention: A great user experience ensures that customers are not only converted but also retained. Users are more likely to return to a website they find easy to navigate and enjoyable to use.
  3. Competitive Advantage: Companies that successfully implement both CRO and UX have a competitive edge. They offer a seamless experience that attracts and retains customers, making it more likely that users will choose their brand over competitors.

Understanding the difference between CRO and UX is critical for creating a website or landing page that not only meets the needs of your users but also drives conversions. While CRO focuses on optimising specific elements to increase conversions, UX design ensures that the overall user experience is seamless, intuitive, and enjoyable.

Both disciplines are essential for business success, and when done correctly, they complement each other perfectly. By improving both UX and CRO, you create a website that not only attracts visitors but also converts them into loyal customers.
