A slow Shopify store is a leaking revenue pipe. We audit, diagnose, and fix every performance bottleneck — delivering sub-second load times that boost your SEO rankings, conversion rates, and customer experience.

Google's research shows that 53% of mobile visitors leave a page that takes longer than 3 seconds to load. For an eCommerce store doing $50K/month, a 1-second delay can mean $12,000+ in lost annual revenue.
Every additional second of load time directly reduces your conversion rate. A store loading at 4 seconds is hemorrhaging revenue compared to a sub-second competitor.
More than half of your mobile traffic — which is likely 70%+ of your total traffic — will leave before they even see your products if your store is slow.
Google uses Core Web Vitals as a ranking signal. Stores that pass all three metrics see measurable improvements in organic search visibility.
Our clients see an average 2.1x conversion lift after optimization. Speed is one of the highest-ROI investments you can make for your store.
Convert to WebP/AVIF, implement responsive srcset, lazy load below-the-fold images, and compress without visible quality loss. Typically saves 40-60% of page weight.
Remove unused app scripts, defer non-critical JS, tree-shake dead code, and break up long main-thread tasks. Most Shopify stores have 30-50% unnecessary JavaScript.
Inline above-the-fold CSS, async load the rest, eliminate render-blocking stylesheets, and reduce CSS specificity bloat from accumulated theme edits.
Refactor expensive Liquid loops, reduce nested for-loops, optimize collection filtering, minimize template rendering time, and eliminate redundant section loads.
Audit every installed app for performance impact. Remove unused apps, replace heavy apps with lightweight alternatives, and consolidate functionality where possible.
Implement font-display: swap, preload critical fonts, subset unused characters, self-host Google Fonts, and eliminate Flash of Invisible Text (FOIT).
Audit and defer analytics, chat widgets, tracking pixels, and social embeds. Implement script loading strategies that prevent third parties from blocking your main thread.
Add preconnect for critical third-party origins, prefetch key navigation routes, and preload hero images and fonts for instant visual rendering.
Set explicit width and height on all media, reserve space for dynamic content, prevent ad and banner layout shifts, and fix font-swap jumps.
Every project ends with a production-ready Shopify store and these tangible outputs.

No. We work on a staging environment first and test everything thoroughly before pushing to production. We never remove functionality — we optimize how it loads. Every change is documented and reversible.
On average, we improve Lighthouse scores by 50-70 points and reduce LCP by 60-80%. A store loading at 4 seconds typically drops to under 1 second. The exact improvement depends on your current state, but we always provide a realistic estimate after our initial audit.
Shopify stores accumulate technical debt over time. App installations add scripts, theme updates pile on CSS, and content changes introduce unoptimized images. Even if you have not changed anything recently, the cumulative effect of these additions degrades performance.
Yes, always. In fact we prioritize mobile because over 72% of eCommerce traffic comes from mobile devices. Google also uses mobile scores for ranking. We test and optimize for both, but mobile is where we focus the most attention.
Our optimizations are permanent, but new app installations, content changes, and theme updates can introduce new performance issues. That is why we offer a Performance Retainer plan for stores that want continuous monitoring and quarterly re-optimization.
Yes. Research consistently shows that faster load times lead to higher conversion rates. Our clients see an average 2.1x conversion lift after optimization. Amazon found that every 100ms of latency cost them 1% in sales. Speed is one of the highest-ROI investments you can make.
Fast pages are the foundation. CRO takes it further with A/B testing, checkout optimization, and UX improvements that maximize revenue per visitor.
