7. Speed Up Your Experience

Real-World Case Studies: Better Design = Real Results

1. HubSpot: CTA Optimization

• HubSpot changed from a generic call-to-action of “Download” to a value-based call-to-action of “Get your free guide” and lead generation increased by 121%. 
• The change was purely the text of the call-to-action was updated, the size of the call-to-action was increased, and it was a color that wasn’t as similar to the surrounding elements; drawing the users eye.

2. Airbnb: Making the UX Easier

• Airbnb redesigned their booking flow on both the app and website. The redesign simplified the user experience and reduced steps in the reservation process. 
• They also added better color palettes, image designs, and layouts in general. The results? 25% more completed bookings from when the process just required fewer steps, as well as an ability to tell visual stories within their content.

3. Walmart: Load Speed Optimization

• Walmart did a series of performance tests across their web properties and found that for every 1 second improved load time, there was a 2% gain in revenue. 
• Designers focused on keeping pages as simple as possible, reducing file sizes, and allowing the calls-to-action that they really cared about, above the fold.

4. Basecamp: New Homepage redesign

• Basecamp’s team completed work on a website redesign of their homepage by providing the user with clarity: clearing clutter, making the messages sharper, enhancing visual hierarchy, etc. 
• This led to an increase of 14% in sign-ups within the first week of the new version releasing.

5. Trello: Visual Demos

Trello added a short explainer video as well as some visual interactive elements to their product pages. The two changes led to an increase in time-on-page and a not less than 20% increase in conversion rate.

Conclusion: Design for Conversions, Not Just Looks

Good design isn’t decoration, it’s persuasion. It grabs attention, builds trust, and guides action. From mobile responsiveness to CTA placement, every design decision can either lift or limit your conversion potential.

Take action

• Audit your landing pages for visual clarity and hierarchy.
• Use A/B testing tools to fine-tune your CTAs, colors, and layouts.
• Keep user psychology at the core of every creative decision.

Remember: The fastest path to more conversions isn’t more traffic, it’s better design.
