UX/UI Design: how to convert your visitors into customers
Why UX/UI design is crucial for your conversion
A beautiful but difficult-to-use website does not convert. The difference between a visitor who buys and one who bounces often comes down to the 3 seconds after arrival.
UX/UI design is not visual glitter — it is a science: the art of guiding the user toward the action they want to take, without friction. At Kreatech, we have seen sites increase their conversion by 40% simply by reorganizing the user journey.
1. Fundamental principles of UX Design
Clarity first
The user must understand within 5 seconds:
- Who are you? (Logo + tagline)
- What do you offer? (Value proposition)
- What do you want me to do? (Main CTA)
Visual hierarchy
Use size, color and white space to guide attention:
- Main title: Large size, contrasting color
- Subtitles: Smaller, secondary color
- Body text: Small size, readable
- CTA: Strong contrast, well spaced
Consistency
The same elements must behave the same way everywhere:
- Same color palette (2-3 colors max)
- Same typography (2 fonts max)
- Same spacing and padding
- Same icons for same actions
2. Web Ergonomics: the art of user flow
Intuitive navigation
The user must never wonder "How do I get there?"
- Horizontal or sticky menu for quick access
- Breadcrumbs on deep pages
- Visible search engine if >50 pages
- Footer with important links (legal notice, contact, FAQ)
Mobile First
60% of traffic comes from mobile in Morocco. Your site MUST be mobile-optimized:
- Readable text without zooming
- Spaced buttons (minimum 44x44px)
- No intrusive popups
- Well-visible hamburger menu
- Form in 1-2 pages max
Loading speed
Every second counts. A page that takes more than 3 seconds to load loses 40% of visits.
- Compress images (TinyPNG)
- Minify CSS/JS
- Use caching
- Lazy-load images below the fold
3. CTA (Call-To-Action): where and how to place them
Golden rules for CTAs:
- Placement: Visible without scrolling (above the fold) + end of content
- Action text: Imperative verb. E.g.: "Request a quote" instead of "Submit"
- Color: Strong contrast with the background (if blue background → orange/red CTA)
- Size: Large enough to be clickable (mobile = 44px min)
- White space: Space around so it "breathes"
4. Forms: how not to lose 70% of your prospects
Fewer fields = more conversions
Each additional field reduces conversions. Example:
- 1 field: 100% conversions
- 3 fields: 80% conversions
- 5 fields: 60% conversions
- 7+ fields: 35% conversions
Simple and effective optimizations
- Clear labels: No hidden label in placeholder
- Real-time validation: Immediate feedback on invalid email/phone
- One column: No 2-column layout on mobile
- Visible button: No scrolling needed to see the submit button
- Consent checkbox: Clearly visible, not pre-checked
5. A/B tests for continuous optimization
Don't guess — test!
Elements to test first
- CTA color: Green vs Orange vs Red (impact: +15%)
- CTA text: "Request a quote" vs "Get a free consultation"
- Form length: 3 fields vs 5 fields
- Form placement: Sidebar vs embedded in content
- Main title: Different value propositions
Tools for A/B testing
- Google Optimize: Free, integrated with Google Analytics
- Optimizely: Premium, powerful for large volumes
- VWO (Visual Website Optimizer): Good value for money
6. The most common UX/UI mistakes:
- ❌ Autoplay videos without user control
- ❌ Intrusive popups that appear immediately
- ❌ Too many colors (loss of consistency)
- ❌ White text on light background (no readability)
- ❌ Slow or hidden navigation
- ❌ Too many ads/banners (lower conversion rate)
Conclusion
UX/UI design is not an option — it is a business strategy. Every pixel has an impact on your conversion.
Start with analysis: measure your bounce rate, your user journey (with Hotjar), identify bottlenecks. Then test, optimize, measure again.
At Kreatech, we have seen small Moroccan SMEs triple their conversion just by applying these simple principles. Your turn!
