You build a website, but does it offer the best user experience for optimum conversions? Without the right UX/UI best practices in place, even the most visually appealing sites can suffer from low impressions, poor CTRs, and weak engagement. A lot of it comes down to the front-end designers and developers who fail to factor in key UI/UX metrics, and your business ends up with a mildly aesthetic but otherwise cluttered site.
Inconsistent design, confusing navigation, or unresponsive layouts can quietly undermine user trust, lower engagement, and hurt conversions. Great UI/UX design, on the other hand, is not just about aesthetics — it is about performance, accessibility, responsiveness, and alignment with user behavior.
In this article, we break down 10 essential UX/UI best practices that can transform your website into a high-performing, user-first platform. These are the same principles Altumind follows to help clients build digital experiences that engage, convert, and retain.
Top 10 UX/UI Best Practices
1. Performance: Slow page loads diminish user experience (UX) and increase bounce rates. You must optimize your Core Web Vitals — CLS, FID, and LCP — optimize your database, compress multimedia assets, and use a Content Delivery Network (CDN). Minify CSS, JavaScript, and HTML, reduce server response time, eliminate render-blocking resources, and regularly audit site performance using tools like Lighthouse or GTmetrix.
2. Responsiveness: Frustration from poor mobile experiences leads to drop-offs. Ensure a mobile-first, intuitive design using responsive frameworks like Bootstrap or Tailwind. Optimize for multiple screen sizes, adjust typography for readability, use scalable images and icons, and prioritize essential content for smaller screens.
3. Images: Images breathe life into a webpage, but when used randomly, can bloat the same and diminish user experience. Use icons and visuals meaningfully, use proper formats (JPEG, PNG, WebP, or AVIF), compress images using TinyPNG or ImageOptim, cache images, and reduce dimensions. Avoid using large resolution images unnecessarily, enable HTTP/2 for faster loading, preload key images, use sprites to reduce HTTP requests, try adaptive device-specific delivery, and finally audit image assets and remove unused files.
4. Accessibility for all users: Make your website inclusive. Add descriptive alt-text, transcripts, semantic HTML, and accessible forms. Follow the latest WCAG guidelines. Consider screen reader compatibility, readable color contrast, and structured headings. As Design should not just work for most it should work for everyone.
5. Call-to-Actions (CTA): CTAs get users to buy or drop a lead for your business. So, you want them to be clear and concise. Keep them short & relevant, use action-oriented text such as “Get Started,” “Claim Your Offer,” etc., and maintain consistency across the page, avoid clutter, and have more whitespace instead. Optimize CTAs for mobile devices, position them strategically, and place primary CTAs above the fold. Always A/B test them to arrive at the best converting one.
6. Forms: Keep forms short and user-friendly. Minimize the number of fields, auto-format entries, and use clear validation cues. Consider multi-step flows for complex data and tailor forms for mobile entry. A well-designed form is the difference between a lost lead and a conversion.
7. Whitespace: Whitespace reduces cognitive overload, leading to higher engagement. Whitespace enhances readability and improves user focus. Maintain consistent spacing, avoid clutter, and balance visuals with text and leave sufficient margins between sections and to the left and right of the page content.
8. Videos: Videos are a great way to captivate resources, but they tend to get a bit heavy on the page resources. So, avoid auto-playing videos, only preload the metadata, use compressed formats, implement lazy loading, and optimize thumbnails. Keep load time in check and prioritize usability across devices.
9. Pop-ups: Pop-ups are a great asset for catching user attention and highlighting offers but can disturb user experience. So, limit the number of intrusive pop-ups per session, minimize heavy animations, compress text and image assets in it, make them responsive, use lightweight pop-up scripts, reduce HTTP requests, and use succinct messaging in pop-ups. Further, defer loading non-essential elements, avoid auto-play videos, prefetch resources for critical ones, and update outdated frameworks or libraries used in them.
10. Textual Content: Content is good for SEO and for readers but stick to some hygiene standards. Keep content concise, structured, and SEO-optimized. Use readable fonts, break text into digestible sections, and maintain brand tone. Clear content enhances both usability and discoverability. Further, localize content for multilingual websites, add metadata, use descriptive anchor text, left-align body content, and center-align headings, and fact-check the content.
Final Thoughts: UX/UI Best Practices
Your website is your digital identity, and the UX/UI is the personality and voice that shape how your site is perceived, not just by bots/crawlers for SEO but mainly by users. A bad sitewide UX/UI can leave a terrible first impression, ultimately affecting your branding, revenue, and profits.
