UX Performance Optimization for Web Services

I use my personal GitHub pages website as a testing ground for AltCSS. It's built purely using HTML, with AltCSS directly applying the native styles. So, it's super lightweight, embraces native HTML with zero overhead. The metrics reflect the same. Some trivia for frontend engineers. What do these metrics in the second screenshot actually mean? In short they are what we refer to as "Core Web Vitals". 1. First Contentful Paint (FCP): The time it takes for the first piece of content (like text, image, SVG, etc.) to appear on the screen after the page starts loading. The lower it is, the better UX and fast page loading. 2. Largest Contentful Paint (LCP): Time it takes for the largest visible element (like a big image, heading, or video) to render on the screen. Always make sure to check what's your largest element and what optimizations can be done. For example, if you are loading a big image, you can think of loading it in WebP format for supported browsers as it would load faster, decreasing the LCP value. 3. Total Blocking Time (TBT): The total time during which the main thread is blocked and the browser can't respond to user input (e.g., clicks, typing). Interestingly even the ChatGPT website suffers from a TBT issue where the input chat box is unresponsive on page load instance and can reload or empty out the instantaneous text you type. Shows how even a top traffic websites with the best engineers are not able to get it right. 4. Cumulative Layout Shift (CLS): Measures how much visible elements shift around as the page loads. This is not always a bad thing depending on your usecase. For example, I have added an artificial layout shift on the TechFlix landing page to a nice transition of loading and animation for better UX. Alternatively CLS is often very poor in most news websites due to "ads" and unnecessary popups that block content or shift the layout. 5. Speed Index: A score that represents how quickly visible content is populated during page load. This can be terrible for data intensive applications. A neat trick is to always statically serve the first batch of data that is to be shown on the screen. After the page loads and the user performs an action, you can update the data dynamically. For example if you have a table where you want to show the first 10 records on page load, don't make an API call. Instead, serve the first 10 records alone as direct static data. Only when the user goes to page 2, fetch from the API. If the user comes back to page 1, you can do a prefetch and cache that data (to ensure its fresh). Bottomline: Landing pages, Pricing pages, and Pages with key calls to actions and important data widgets must be optimized for the best web vitals to ensure better search indexing and UX for the end user. This often translates to a step percentage increase in CTA clicks, time spent on websites, etc.

A client spent over $400,000 on an app that barely worked. We took it over about 4 months ago. REALITY CHECK: Their previous dev team left them with: • Unstable codebase • Frustrated client and users • Monthly crashes • Zero scalability • Bleeding money Most agencies would rebuild from scratch. We did something different. Step 1: Deep dive technical audit Analyzed 50,000+ lines of code Found over 100 critical bugs Identified several security vulnerabilities Step 2: Strategic stabilization Fixed core functionality Patched security holes Optimized database queries Reduced load time by 73% Step 3: UX transformation Redesigned key user flows Simplified navigation Added performance monitoring Improved accessibility score by 89% Current status: • Zero downtime in 120 days • 94% reduction in user complaints • 40% faster load times • Platform ready for scaling Building from scratch can cost more. Smart optimization saves money. What we learned: Technical debt compounds like financial debt. Early fixes prevent costly rebuilds. User experience drives retention. Speed matters more than features. We're now building their next phase. Faster. Better. More scalable. Your software should work for you, not against you. Agree? Like and share your rescue story below.

The Secret to Winning at Web Performance Optimization? Teamwork! After years in the web performance game and chatting with tons of customers, I've had a 💡 moment: The number one ingredient for nailing web performance optimization? It's all about different teams working together, especially UX and performance folks. This really hit home recently when I was talking to a customer about their web performance journey. They shared a golden nugget they've picked up along the way: When you knock down the walls between UX, IT, and performance teams, you get a much more well-rounded approach to making your website awesome. Here's their recipe for success: 1. Learning Together: They kicked things off by giving their UX team a crash course on Largest Contentful Paint (LCP), helping them see how their design choices can make or break this super important metric. 2. Bringing More Minds to the Table: This teamwork has snowballed to cover other Core Web Vitals like Cumulative Layout Shift (CLS). Now, the performance crew works hand-in-hand with UX to strike the right balance between looking good and running smoothly. 3. Show, Don't Just Tell: They use heat maps to highlight the most-clicked areas and pair this with performance stats to figure out what to fix first. This visual approach helps the UX team really get their heads around the performance data. 4. Tackling Problems as One: By getting UX involved in performance chats, they're solving tricky issues like unexpected layout shifts caused by translated text — a problem that needs both design smarts and tech know-how. The end result? Better performance that doesn't sacrifice user experience, and vice versa. Here's the takeaway: The best websites come from teams joining forces, with everyone bringing their A-game to the table. So, how about you? Are you encouraging this kind of teamwork in your company? If not, what's standing in your way? #frictionless

Slashed a Webflow site's load time from 6.2s to 1.8s Client's reaction: "How did you do this without rebuilding?" The secret? 5 unconventional optimizations. Here's the full breakdown 👇 The site was beautiful but slow. Killing their Google rankings. And losing mobile visitors. The unexpected culprits: → Oversized background images → Unoptimized CMS queries → Multiple font families → Heavy custom code → Nested interactions Here's exactly what we did: 1. Images: → Converted to AVIF → Added lazy loading → Removed unused assets 2. Interactions: → Combined similar ones → Used CSS where possible → Removed scroll-based triggers 3. Code cleanup: → Removed jQuery dependencies → Merged custom scripts → Minified everything The results shocked everyone: → Mobile speed: 1.8s → Core Web Vitals: All green → Mobile conversions: +27% → Bounce rate: -41% Best part? No design changes are needed. Want the same speed gains? DM "Speed Check" for a FREE performance audit.

The most overlooked aspect of UX: performance. Did you know 53% of users abandon a site if it takes longer than 3 seconds to load? We live in a world where your users expect things NOW. A fast-loading, well-designed site can make all the difference between losing a potential customer and making a sale. Improving your site’s speed and user experience can be easy. Try these 3 tricks: • Compress images: Large image files can slow down load times. Use formats like WebP and tools like TinyPNG to compress images without losing quality. • Limit animations: Fancy animations might look cool, but too many can cause slow loading and distract users from their journey. Keep it sleek and purposeful. • Use lazy loading: This technique delays the loading of non-essential content until it’s needed, speeding up initial page load times. At Orizon, we help companies create lightning-fast, intuitive platforms that keep users engaged and coming back for more.
