What Is Conversion Rate Optimization (CRO)?
Conversion rate optimization (CRO) improves a landing page’s ability to convert visitors into customers through analysis of user behavior and strategic design changes.
How does it work? CRO web design identifies areas where users encounter friction or confusion that may prevent them from taking action on your landing page.
Resolving these issues helps guide visitors toward completing specific goals, such as filling out a form, making a purchase, signing up for a service or downloading a resource.
What Is UI/UX Design?
UX UI design focuses on creating a seamless and enjoyable experience for website visitors. While often mentioned together, UI is actually a specialized subset of UX.
• UX (user experience) Design ensures the product is easy to use, intuitive and meets user needs. It covers everything from functionality to the overall flow of interactions, aiming to provide a smooth and satisfying journey.
• UI (user interface) Design deals with visual and interactive elements like buttons, menus and layouts. Its goal is to create an appealing and consistent design that enhances usability and complements the user experience.
How UI/UX Design Affects CRO
UI/UX design is critical to any CRO landing page strategy. When visitors arrive on a website, they usually have specific goals, such as finding information, purchasing or contacting the company.
A well-executed UX UI design helps them effortlessly achieve these goals, whether that be through improving site navigation, reducing load times or ensuring mobile responsiveness.
Here’s how you can integrate UX and CRO in your landing page strategy to build a high converting website:
• UX research identifies user behavior patterns. Analyzing how visitors interact with your site reveals where they drop off or hesitate, helping you make targeted improvements to boost conversions.
• UX insights guide CRO experiments. A/B testing becomes more effective when based on data from UX research. Understanding user behavior allows you to test meaningful changes that impact conversions.
• Good UX makes conversions feel intuitive. Reducing friction in the user journey ensures customers end up where they need to be. An intuitive, user-friendly site encourages visitors to convert without frustration.
• Consistent UX UI design builds trust. A cohesive design across pages fosters trust and credibility. Visitors are more likely to take action when the site feels professional and reliable.
• Micro-interactions create engagement. Subtle animations or feedback, like button clicks or hover effects, provide a more interactive experience that keeps users engaged and encourages them to explore further.
The Psychological Principles Behind a High Converting Landing Page
Understanding how your customers think, act and make decisions is key to good UI UX design and creating a high converting landing page.
Here’s how you can use key psychological principles to design effective, conversion-driven pages:
1. Hick’s Law: Simplify Choices to Reduce Decision Fatigue
Hick’s Law states that the more choices a person has, the longer it takes for them to make a decision. On a landing page, too many choices can overwhelm visitors, leading to decision fatigue and potential abandonment.
To optimize landing pages for conversions, simplify the options available to visitors. If you offer three subscription plans, for example, highlight the best option for users.
Shopify, a leading eCommerce platform, does this by placing a “Most Popular” tag on its most recommended plan. It also clearly lists the features in each package and specifies which option is best for solo entrepreneurs, small teams, growing businesses or large enterprises.
2. The Fogg Behavior Model: Align Motivation, Ability and Triggers
The Fogg Behavior Model states that three elements must converge for a user to take action: motivation (a reason to act), ability (ease of performing the action) and a trigger (a prompt to act).
On a high converting landing page, this means offering a compelling reason for the user to act (motivation), making the action simple and easy to perform (ability) and providing a clear prompt, such as a strong CTA (trigger). This alignment increases the chances of users following through on their intent.
Check out this low-friction, no-fuss CTA example from produce delivery brand Imperfect Food:
3. The Rule of Thirds: Guide Attention with Visual Hierarchy.
The rule of thirds is a design principle that helps create balance and visual appeal on a landing page. It divides the page into a grid of nine equal sections using two horizontal and two vertical lines.
These grid intersections act as focal points where key elements like headlines, images and CTAs can be placed to naturally draw attention and improve user engagement.
The top left intersection is where the eye scans first, receiving 41% of the visual attention. The bottom left intersection gets 25%, the top right intersection gets 20%, and the bottom right intersection gets 14%.
This means viewers are most likely to focus on the top left corner first and the bottom right corner last. Use this pattern to strategically place your most important elements in areas that attract the most attention.
4. Social Proof
Social proof is the concept that people are influenced by the actions, opinions and experiences of others. A high converting website design typically uses various types of social proof, including:
• Customer Testimonials: Quotes from satisfied customers sharing their positive experiences.
• Case Studies: Stories showing how your product or service solved a problem.
• Trust Badges: Certifications, awards or security seals to reinforce credibility.
• User Statistics: Metrics like “Trusted by 10,000+ customers” or “4.8-star rating from 500 reviews” that emphasize social approval.
Nori uses social proof well by displaying reviews from trusted publications, such as Forbes and The Daily Post.
They also used a star rating system and incorporated reviews from verified users.
5. Fear of Missing Out (FOMO): Create Urgency to Drive Action
FOMO is a powerful motivator that plays on people’s fear of losing an opportunity. You can optimize landing pages by adding elements that drive urgency, like countdown timers, limited-time offers, flash sales, exclusive memberships or low-stock warnings to encourage immediate action.
Here’s an example from Iconica:
Another CRO UX best practice that builds FOMO is using exit intent popups like what OptinMonster did here:
An exit intent popup appears when visitors are about to leave your site. It offers a final chance to engage them, helping reduce cart abandonment, grow email subscriptions, generate leads and improve website engagement.
10 Tips on How to Optimize Landing Pages for Higher Conversions
Now that you know the basics of UI UX design and its role in creating a high converting website design, let’s break down a few CRO web design practices to take your landing page to the next level.
1. Offer Something Valuable
Every landing page should present a clear, valuable offer in exchange for the desired action. Offering too many choices can overwhelm visitors. Stick to one clear offer that aligns with their goals, whether it’s a discount, free consultation or downloadable resource.
Pages with multiple offers can reduce conversions by up to 266% (Mailchimp).
2. Write a Headline That Promises Value
Your headline should grab attention and communicate the benefits of your product or service. Visitors need to know they’ve landed in the right place and that your offer meets their needs.
For example, instead of a generic headline like “Welcome to Our Website,” use something like “Save 50% on Business Essentials Today” to immediately convey value.
3. Eliminate Distractions
Landing pages are designed with a single goal: converting visitors. Remove navigation menus, external links and any unnecessary elements that might pull users away. A clean, distraction-free CRO web design keeps visitors focused on your offer, increasing the likelihood of conversion.
4. Make Your CTA Impossible to Miss
Your CTA should clearly tell visitors what to do with action-oriented language like “Get Started” or “Download Now.” Use contrasting colors to make the button stand out and position it prominently on the page.
To draw attention to your form, add a directional cue, such as an arrow or line, in the header pointing toward it. This subtly guides users to your conversion goal.
5. Use Testimonials and Reviews to Build Trust
Social proof, such as reviews, testimonials or trust badges, helps build credibility and trust with visitors. People are more likely to believe feedback from other customers than claims made by a business.
Adding real testimonials or showcasing statistics like “Trusted by 10,000+ Customers” reassures visitors they’re making the right choice.
6. Optimize UI UX Design for Mobile
Almost 96.2% of global users access the Internet via mobile phones (Statista). To optimize landing pages for mobile:
• Responsive Design: Create layouts that automatically adapt to different screen sizes and orientations.
• Simplified Navigation: Use a straightforward navigation structure, like a hamburger menu, to easily access various sections of your site.
• Optimized Touch Targets: Ensure buttons and links are large enough and well-spaced for effortless tapping on touchscreens.
• Fast Load Times: Compress images and optimize code to maintain quick loading, even on slower mobile networks.
• Readability: Use larger fonts and proper line spacing to make text easy to read on small screens.
• Minimize Pop-Ups: Limit pop-ups, as they can be frustrating and hard to close on mobile devices.
• Test your landing page on various devices to ensure a seamless and enjoyable user experience.
7. Include the Lead Form Above the Fold
Place your lead form or an anchor link above the fold, ensuring it’s visible when visitors land on the page. This makes it easy for prospects to convert immediately without needing to scroll. Consider a form layout that scrolls with the user to keep the conversion point accessible.
8. Reduce Page Load Times
Page load speed is a confirmed ranking factor for both desktop and mobile. Google states that pages with slow load times are less likely to rank well in search results.
To improve page speed:
• Optimize images: Compress and resize images to reduce file size while maintaining quality.
• Minimize HTTP requests: Reduce the number of scripts, images and stylesheets that need to load.
• Enable browser caching: Store data locally on users’ devices to speed up repeat visits.
• Use a Content Delivery Network (CDN): Distribute content across multiple servers to serve data from locations closer to users.
• Optimize code: Minify CSS, JavaScript and HTML to reduce file size and remove unnecessary code.
• Leverage asynchronous loading: Allow elements like JavaScript to load without delaying the rest of the page.
9. Create Accessible UI/UX Design
An accessible UI/UX design ensures your website can be used by all visitors, including those with disabilities. Accessibility is essential for inclusivity, improves overall usability and is key to creating a high converting website design.
Here are some CRO UX best practices for creating accessible content and design:
• Use Alt Text for Images: Provide descriptive alternative text for images to assist users who rely on screen readers.
• Use Color Contrast: Ensure text and background colors are distinguishable for users with visual impairments.
• Simplify Navigation: Enable keyboard navigation for all interactive elements to accommodate users with motor limitations.
Add Scalable Fonts and Clear Headers: Use easily adjustable fonts and structured headings to make content readable and navigable for users with cognitive or visual impairments.
• Provide Captions and Transcripts for Multimedia: Add captions to videos and transcripts for audio content to support users with hearing impairments.
• Use Clear and Simple Language: Write in a way that’s easy to understand for many users.
10. A/B Test Everything
Even if you follow CRO UX best practices, what works for one audience might not work for another. A/B testing allows you to experiment with different elements on your landing page to see which performs best.
To conduct A/B testing:
• Test One Element at a Time: Focus on a single variable, like a button color or headline, to isolate its impact on conversions.
• Define Clear Goals: Identify specific metrics to measure, like click-through rates, form submissions or purchases.
• Gather Enough Data: Run tests long enough to ensure statistically significant results before making changes.
• Refine Based on Insights: Use the results to optimize landing pages and continually improve their performance.
