Every 100ms of delay costs you 1% in conversions. We optimize your Shopify store's speed to score 90+ on PageSpeed, load in under 2 seconds, and pass all Core Web Vitals — guaranteed.
We'll analyze your store and show what's slowing it down
A 1-second delay in load time costs you 7% in conversions. We engineer every millisecond — Core Web Vitals, server response, rendering path — until your store is genuinely the fastest in your niche.
Surface-level fixes don't cut it on Shopify. We go deep into the rendering pipeline, eliminating every unnecessary byte and blocking request that slows your store.
Native and intersection-observer lazy loading for images, videos, and below-the-fold sections — loads only what the user sees.
Defer, async, and preload strategies applied to eliminate render-blocking scripts and stylesheets that delay First Contentful Paint.
Subset fonts, preconnect to foundries, use font-display:swap — eliminate layout shift and invisible text during font load.
Identify and defer or remove bloated analytics, chat widgets, and pixel scripts — the #1 hidden cause of slow Shopify stores.
We've optimised hundreds of Shopify stores. Our process is proven, precise, and fast — you'll see measurable improvements in your Core Web Vitals within days, not months.
Full Lighthouse, GTmetrix, and CrUX analysis. We identify every bottleneck and produce a prioritised fix list with estimated impact scores.
Hands-on code changes — image pipeline, script management, CSS critical path, server config, and CDN rules — deployed to staging then production.
Ongoing RUM monitoring, monthly Lighthouse reports, and proactive alerts when app updates or new content degrades performance.
Every millisecond shaved off your load time directly impacts your bottom line. Our clients don't just get a faster store — they see real revenue gains within the first month.
Speed is not a side service for us — it's core to everything we build and everything we optimise. We know Shopify's rendering architecture better than anyone, and we have the audit track record to prove it.
We don't just install an image compressor and call it done. We systematically address every factor that affects your store's speed.
WebP conversion, lazy loading, responsive srcsets, and proper sizing. We cut image payload by 60-80% without visible quality loss.
Remove unused CSS and JavaScript, minify and defer render-blocking resources, and eliminate dead code from uninstalled apps.
We identify which apps are bloating your store, remove leftover code from uninstalled apps, and suggest lighter alternatives.
Defer, async, or lazy-load third-party scripts (analytics, chat, reviews). We reduce their impact on initial page load by 70%+.
Inline critical CSS, add preconnect/preload hints, and optimize font loading to eliminate render-blocking and improve LCP.
LCP, FID/INP, and CLS — we address each metric specifically. Layout shift prevention, interaction optimization, and paint timing improvements.
Deep analysis of your store's performance using Lighthouse, WebPageTest, and real-user monitoring data. We find every bottleneck.
Prioritized list of fixes ranked by impact and effort. You see exactly what we'll do and the expected improvement for each fix.
We implement all optimizations on a staging theme, test thoroughly, then deploy to production. Zero downtime, zero risk.
Before/after metrics, Core Web Vitals comparison, and ongoing monitoring recommendations. You see the exact improvement we achieved.
Every additional second of load time reduces conversions by 7%. A 4-second store loses 28% more customers than a 1-second store.
53% of mobile visitors leave if a page takes longer than 3 seconds to load. Most Shopify stores take 4-6 seconds on mobile.
Google uses Core Web Vitals as a ranking signal. Failing CWV means lower search rankings, less organic traffic, and higher CAC.
Jhango's speed optimization team has optimized over 500 Shopify stores, achieving 90+ PageSpeed scores consistently. Unlike generic developers who install a caching app and call it done, we perform deep technical audits and implement systematic fixes across images, scripts, CSS, third-party tags, and server-side rendering for measurable results.
Measurable speed improvements that translated directly into higher conversions and revenue.
Fashion brand went from PageSpeed score of 24 to 92. Load time dropped from 6.2s to 1.4s on mobile, directly boosting mobile conversion rate by 31%.
Skincare brand's store went from failing all Core Web Vitals to passing with green scores. The speed improvement drove a 23% lift in checkout completion rate.
Electronics store cut mobile bounce rate from 62% to 34% after speed optimization. More visitors staying on-site meant more products viewed and more sales.
We target 90+ on Google PageSpeed Insights for desktop and 75+ for mobile (mobile is harder due to Shopify's platform constraints). Most stores see a 2-4x improvement in their score. We guarantee green Core Web Vitals scores (LCP under 2.5s, FID under 100ms, CLS under 0.1) or we keep working until we hit them.
No. We implement all changes on a duplicate staging theme first and test everything thoroughly before deploying to production. Every optimization is tested across devices and browsers. We also keep a full backup of your original theme so we can roll back instantly if needed. Zero downtime, zero risk to your live store.
Most speed optimization projects are completed in 5-7 business days. Day 1-2 is the deep audit and optimization plan. Days 3-5 are implementation. Days 6-7 are testing and deployment. Complex stores with heavy customization or many third-party integrations may take up to 10 days. You will see progress updates throughout.
We do manual, code-level optimization -- not app installations. Speed apps add their own JavaScript overhead and often provide superficial fixes. Our approach involves manually editing your theme's Liquid templates, CSS, and JavaScript to eliminate bloat at the source. This delivers deeper, more sustainable performance improvements.
Core Web Vitals are Google's metrics for page experience: LCP (Largest Contentful Paint) measures load speed, FID/INP measures interactivity, and CLS measures visual stability. Google uses these as ranking signals, meaning slow stores rank lower in search results. Passing Core Web Vitals improves your organic search visibility, reduces cost per acquisition, and provides a better shopping experience.
We never remove apps without your approval. During the app audit, we identify which apps are adding the most load time and which provide the least value. For essential apps, we optimize how their scripts load (defer, async, lazy-load). For non-essential apps, we suggest lighter alternatives or custom-coded replacements that achieve the same functionality without the performance hit.
Our speed optimization packages start at $1,500 for basic stores and go up to $5,000+ for complex, highly-customized Shopify Plus stores. The exact price depends on your current score, number of apps, theme complexity, and target metrics. We provide a free speed audit that includes a detailed quote with expected improvements before you commit.
Yes, mobile speed optimization directly impacts conversion rates because over 70% of ecommerce traffic comes from mobile devices. A one-second improvement in mobile load time can increase conversions by 10-20%. Our optimization specifically targets mobile performance by reducing render-blocking resources, optimizing images for smaller screens, and minimizing JavaScript execution time on mobile processors.
Absolutely. Our speed optimization preserves your store's visual design pixel-for-pixel. We optimize the underlying code, image delivery, script loading, and resource prioritization without altering how your store looks or functions. In rare cases where a design element is severely impacting performance, we will discuss alternatives with you before making any visual changes.
We implement modern image formats like WebP and AVIF, configure responsive srcset attributes so mobile devices load smaller images, add lazy loading for below-the-fold images, and preload critical hero images. We also audit your image library for oversized uploads and optimize them without quality loss. Proper image optimization alone can cut page weight by 40-60% on most Shopify stores.
We optimize your entire store, not just the homepage. Our speed optimization covers the homepage, collection pages, product pages, cart page, and any custom landing pages. Each page template gets individually audited and optimized because they load different resources. Collection and product pages often have the most room for improvement since they handle dynamic content and multiple product images.
Our optimizations are built into your theme code, so they persist permanently. However, adding new apps, installing theme updates, or adding heavy content can gradually impact speed over time. That is why we include 30 days of post-optimization monitoring and provide a maintenance guide. Many clients opt for quarterly speed check-ups to ensure their store maintains peak performance as they add new features and content.
