Improving Checkout Page Load Time

As a Frontend developer it is also important to prioritize performance optimization to ensure the web applications load quickly and provide a smooth user experience. Here's a breakdown of key techniques used for frontend performance optimization: Minification and Compression: Minification involves removing unnecessary characters (such as whitespace, comments, and unused code) from source files to reduce file size. Compression techniques like gzip or Brotli further reduce file sizes by compressing text-based resources like HTML, CSS, and JavaScript before transmitting them over the network. Smaller file sizes lead to faster download times and improved page loading speed. Image Optimization: Images often contribute significantly to page weight and load times. Optimizing images by compressing them without sacrificing quality, using appropriate image formats (such as WebP or JPEG XR), and implementing responsive image techniques (like srcset and sizes attributes) can dramatically improve performance. Additionally, lazy loading techniques delay the loading of off-screen images until they are needed, reducing initial page load times. Caching Strategies: Implementing caching strategies like browser caching, CDN caching, and server-side caching can reduce server load and speed up subsequent page loads. Leveraging HTTP caching headers such as Cache-Control and Expires allows browsers and intermediaries to store and reuse previously fetched resources, minimizing network requests. Asynchronous Loading: Loading JavaScript and CSS files asynchronously prevents them from blocking the rendering of the page, allowing critical content to display faster. Techniques like defer and async attributes for script tags and media attributes for stylesheet links enable asynchronous loading while ensuring proper execution order and avoiding render-blocking behavior. Code Splitting and Bundle Optimization: Code splitting involves breaking down large bundles of JavaScript or CSS code into smaller, more manageable chunks that can be loaded on-demand. Tools like Webpack offer features for code splitting, tree shaking (removing unused code), and optimizing bundle size, helping reduce initial load times and improve runtime performance. Critical Path Optimization: Identifying and optimizing the critical rendering path, which includes the resources necessary to render the initial view of a webpage, is crucial for improving perceived performance. Prioritizing the loading of critical resources (such as CSS and JavaScript required for above-the-fold content) and deferring non-essential resources can accelerate the time to first meaningful paint and enhance user perception of speed. #frontenddevelopment #performanceoptimization #webdevelopment #javascript

The Truth About Website Speed Tests Most tools are lying to you. Want to know why your site's still slow? Because you're using the wrong tools... In the wrong way... And focusing on the wrong metrics. Let me show you what actually works: ✅ The Only Speed Tools That Matter Forget the fancy dashboards. These are your new best friends: → Google PageSpeed Insights (Because Google actually uses this) → GTmetrix (For the technical deep dive) → WebPageTest (For real-world testing) Everything else? Nice to have, but not essential. ✅ The Metrics That Actually Impact Revenue Stop obsessing over "page load time." Focus on these instead: → Largest Contentful Paint (LCP) Must be under 2.5 seconds → Time to First Byte (TTFB) Keep it under 200ms → Cumulative Layout Shift (CLS) Below 0.1 or customers bounce ✅ The Action Steps That Work Most tools give you a list of 50+ things to "fix." Here's what actually moves the needle: ✨ Compress those massive images ✨ Upgrade your cheap hosting ✨ Use a solid CDN ✨ Enable browser caching ✨ Lazy load everything else Real companies saw real results... A Brisbane e-commerce site: • Cut load time from 6.2s to 1.8s • Reduced bounce rates by 21% • Boosted conversions by 14% ✅ The Monitoring That Matters Don't trust single tests. Test from multiple: • Locations • Devices • Time periods Because one good score doesn't mean your site's actually fast. The Truth? Your website speed is probably worse than you think. But here's the good news: You don't need perfect scores. You need real-world performance that: • Keeps visitors engaged • Reduces bounce rates • Drives more sales Stop chasing perfect scores. Start chasing perfect performance. Because in 2025... Speed isn't just about fast loading. It's about faster revenue. Do you agree? :)

🚨 Founders, PMs & Marketers Reminder: if you're focused on CAC, creatives, and funnels, but ignoring site/app performance, you're paying for it but you just don't know it. 🧨 Speed is still the silent killer of conversion. Some 2025 data: ⚡️ 63% of users bounce if a page takes over 4 seconds to load (Portent, 2025) 📱 A 1 second improvement on mobile drives a 3% lift in conversions (Google/SOASTA) 💸 Sites that load in 1 second convert up to 5x better than those that load in 10 (Deloitte Digital) If your checkout is 2 to 3 seconds and your competitor’s is sub-1, you're losing customers before they even click. 📊 Where things stand in 2025 Site/App performance is no longer just a dev concern. It’s a growth lever. Reducing mobile load time by just 1 second boosts conversions by nearly 6% and cuts bounce by 9% (Deloitte Digital, 2025 update) Even a 1 second delay can cause a 7% drop in conversions (Think with Google) Google still recommends a 2–3 second load time for best-in-class e-commerce performance 🛒 Checkout friction still hurts Cart abandonment is stuck around 70% and checkout lag is a major factor (Baymard Institute) BigCommerce data shows frictionless flows meaningfully improve conversion Click-to-Pay has been shown to shave 20 seconds off the process, cut fraud by 91%, and lift conversion by around 10% ([Business Insider, 2025]) 💬 What I keep seeing Plenty of teams are sitting on 2 to 3 second load times in the most critical funnel points—checkout, onboarding, trial setup. It feels fast enough, but it’s driving up CAC and suppressing conversion. In some cases, cleaning up performance delivered a better CAC drop than any new campaign. 🔧 Where to look right now 📏 Audit your load times on mobile and desktop 📉 Clean up image weight, unused JS, API delays 📈 Run a correlation between load speed, conversion, and CAC—you’ll likely be surprised 💡 Bottom line Speed still converts. If your CAC is creeping and everything else looks solid, your load time might be the leak. Sometimes the fix isn’t another ad. It’s shaving a few hundred milliseconds off your flow.

Yesterday, an e-commerce client asked how to increase site speed without losing their marketing tracking. Here's our approach. This client is a $100M+ online retailer with a complex channel mix. Thus, they have lots of marketing pixels onsite. Our recommended approach: 1.) Remove libraries and pixels no longer needed. Audit your existing pixels and events. Disable any pixels/events that are no longer needed. Check for errors and fix any broken pixels. 2.) Tag Managers Move all 3rd party javascript (libraries/pixels) into a tag manager. Tools like GTM, Tealium, Adobe Launch benefit primarily help with data governance and standardization. However, tag managers can also minify and cache 3rd party libraries, reducing page load times. Additionally, they often have OOTB capability to set the priority (sequence) of the tags, more on this below. 3.) Server-side tagging Many ad platforms can receive events server-side vs. clientside (through javasript in the browser). Examples include Meta, Google, TikTok. This can take some of the load off the browser. There are good 3rd party tools for this, including Blotout and Elevar. Server-side tracking has the added benefit of restoring signal to the ad platforms. More conversions to the ad platform will result in better optimization and reduced ad spend. 4.) Sequencing Less-important libraries This is a biggie. If pixels aren't required for the page render, have your web-dev team defer them later in the page. This can also be done in the tag manager. Most tag managers load tags asynchronously by default. That means they load in parallel and won't block other resources from loading. Full-service performance optimization tools like Yottaa can automatically sequence the libraries and calls (very good but not cheap). In summary, I'd tackle in this order: - Remove any pixels/libraries you no longer use/need - Move all 3rd party pixels to a tag manager (GTM) - Fix broken pixels - Optimize the load order of the libraries (sequencing) - Setup server-side tracking for ad platforms if available What else would you add? #measure #digitalanalytics #marketinganalytics #ecommerce

In 2025, stop losing customers to slow load times with this 4-part speed checklist: 1. Keep your site lean → Oversized media files slow everything down. Optimize or compress them. → Clean up legacy tags, fields, or data you no longer need. 2. Prioritize loading resources → Too many scripts loading at once? Spread them out smartly. → Identify lagging scripts and decide if they’re worth it. 3. Audit your apps → Remove unused apps. → Look for lighter or API-based solutions. 4. Schedule regular check-ups → Tools like Google Lighthouse can pinpoint what’s slowing you down. → Small optimizations every quarter keep your site running smoothly. These can be small tweaks, but they can definitely create happier customers and better conversions. Anything I missed? Feel free to share your new year checklist for your brand! PS - here’s a little reminder: if you’re on Shopify, use their CDN to help load images faster or optimize them.

If your landing page takes longer than 3 seconds to load, fix these 3 things. (3 secs is the standard before a user bounces) 1) Bloated scripts: Every plugin, tool, script or unnecessary line of code you run on your website adds "weight". The more it carries, the slower it will load. 2) Huge images: Resize and compress or use next-gen formats. Pro tip: Your CDNs should automagically have a way to turn all the images on your website to a next-gen format and have it load faster. It's a matter of a setting. Ask your dev about it. 3) Lazy-load what isn’t critical. After you assess your scripts from step 1, maybe there's an important script but it doesn't need to load right away. Ex. Your chatbot. Have it load a little later. This makes the most critical scripts run first and then loads the rest, making your website load fast. --- If you want to see what's slowing your website down, run a Lighthouse test (Google it or run it in Inspect on Chrome). It will give you a pretty detailed report for free. Fix the technical debt. Then worry about your hero headline. Because if the page doesn't load fast enough, it doesn't matter if you have the best-written website on the planet.
