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.
