Shopify Speed Optimization Agency for DTC Brands
App, theme, and Liquid optimization, engineered to speed up your Shopify store and lift conversions.
Shopify's hosted platform means you cannot touch the server, but there is still a large amount of speed to win. App scripts stacking up, render-blocking theme code, heavy Liquid loops, oversized images, and third-party pixels all drag down your store. Our Shopify speed optimization services audit every app and theme asset, remove the dead weight, and tune image and script delivery so your store loads fast and converts more visitors. We have optimized hundreds of Shopify stores to 90+ PageSpeed scores.
Trusted by leading brands
Our Expertise
Most speed apps promise a one-click fix and add another script to your store. We don't. Every engagement is run by a Shopify speed optimization expert who profiles your store at the code level: every installed app and its scripts, theme and Liquid render cost, and image and pixel weight. Then we cut what is not earning its place and tune the rest.
DTC brands come to us as their Shopify speed optimization agency because we show our work. You get a ranked app-impact report, before and after Core Web Vitals data, and documentation of every change, not a black box. We have optimized hundreds of Shopify stores to 90+ PageSpeed scores and held them there through app updates and theme changes.

Who This Is For
Direct-to-consumer brands where every millisecond impacts conversion rates and ROAS.
Subscription stores need fast checkout and product page loads to reduce churn.
Dropship stores with many products need fast collection and product page rendering.
Enterprise
We optimize Shopify Plus stores at every layer the platform exposes, using the same staging-first methodology with Plus-only levers added on top.
On legacy Plus stores we tune checkout.liquid directly: remove every marketing script from checkout (chat, popups, heatmaps, retargeting pixels), preload payment gateway SDKs (Stripe, PayPal, Braintree, Apple Pay) on the cart page, inline critical checkout CSS, defer non-essential checkout JavaScript, and preconnect to payment provider domains. On newer stores we ship the same wins through Checkout Extensibility, UI extensions, and app blocks so customizations run sandboxed with performance guarantees.
Launchpad lets you schedule flash sales, theme swaps, product publishing, and Script Editor jobs without bolting on a marketing app per campaign, which removes a whole class of campaign scripts from the storefront. Script Editor (and Shopify Functions on newer stores) replaces heavyweight discount, shipping, and payment customization apps with lightweight server-side logic that adds zero client-side JavaScript.
We optimize Plus B2B stores (company accounts, catalogs, price lists, draft orders, net terms) so they replace third-party B2B apps that ship heavy client JavaScript. Expansion stores for new markets, languages, or brands share theme code through theme kits or CI/CD, so the same performance budgets and fixes propagate across every storefront. Shopify Markets is configured for server-side currency and language so the correct locale renders in initial HTML.
For Hydrogen and headless builds on Oxygen we optimize streaming SSR, edge caching, bundle splitting, and Storefront API queries. Targets: under 100KB gzipped per route, code-split by route, lazy-load below-fold sections, and cache-control tuned per page type. Hydrogen is the right call when a Liquid theme cannot pass Core Web Vitals after thorough optimization, when sub-100ms global TTFB is required, and when a React team is available to maintain the build.

We work on a copy of your theme, so your live store is never at risk. We audit and trim apps, refactor Liquid templates, optimize image and script delivery, and fix Core Web Vitals on your product and collection pages. Here is what that covers:
We test every installed app individually , measuring its JavaScript weight, render-blocking behavior, and network requests. You get a ranked impact report and for every slow app, a vetted faster alternative with migration steps so you never lose functionality.
We audit every template for inefficient loops, redundant Liquid logic, and render-blocking patterns. Each template gets a before/after render-time comparison, and we refactor code to cut server response times and improve TTFB across all page types.
We implement responsive srcsets, modern formats (WebP/AVIF), proper lazy loading, and correct sizing for every image. Product images, hero banners, and collection thumbnails are all optimized without sacrificing visual quality.
Every external script (GTM, Meta Pixel, Hotjar, Klaviyo, etc.) is identified and categorized. We defer, async, or remove scripts based on their impact, and provide a full analysis document so your team knows exactly what's running and why.
We target LCP, INP, and CLS individually , fixing layout shifts from dynamic content, optimizing interaction handlers, and preloading critical assets. We monitor real-user CrUX data over 2–4 weeks until all metrics pass Google's 28-day rolling window.
After deployment, we provide 30 days of monitoring to catch regressions from app updates or new content. You also receive a Speed Budget Document with max JS size, image targets, and app limits , so your team doesn't re-break what we fixed.
The Data
On a DTC store, speed is conversion rate. When you improve Shopify site speed, faster product and collection pages keep shoppers moving toward checkout, lift organic traffic from passing Core Web Vitals, and lower your cost-per-click through a better Quality Score. In our study of 37,000 ranking pages, sites that pass Core Web Vitals hold 47.6% of page-one results. The research is consistent across every study:

Our Process
We clone your Shopify store to a secure staging environment and run a full performance audit , PageSpeed, Core Web Vitals, waterfall analysis, and real-device testing. Your live store is never touched during this phase.
Every installed app is tested individually for its JavaScript footprint, render-blocking behavior, and network requests. You receive a ranked report showing exactly which apps are costing you speed , and faster alternatives where they exist.
Over 1–2 weeks, we implement all fixes on staging: Liquid template refactoring, image delivery optimization, script deferral, font loading, and CSS cleanup. Zero downtime to your live store.
We monitor real-user field data (CrUX) over 2–4 weeks, making iterative adjustments until LCP, INP, and CLS consistently pass in Google's 28-day rolling window , lab scores.
Once validated, all changes are migrated to your live store. You receive complete documentation of every change made, a speed budget for future development, and a before/after performance report.
