Shopify Optimization: Boost Your E-commerce Performance

Don't let a poorly designed Shopify theme permanently impact your conversion rates!

< Our web performance experts optimize your Shopify store to meet the highest standards />

Security and traceability of developments

We work on a duplicated theme in preview mode, without ever touching your Shopify store's active theme. Optimizations are applied via the theme editor or deployed via CLI (Shopify CLI) using versioning tools like Git (Github, Gitlab…). This methodology preserves the modification history, which is systematically documented. Your technical teams can thus review and validate each optimization in a test environment before its final deployment.

Proven levers, sustainable efficiency

The performance fixes implemented as part of our Shopify optimizations are based on web standards and the native APIs of modern browsers. Our interventions cover JavaScript, CSS, assets (images, webfonts), and the HTML markup generated by Liquid templates. This approach guarantees the sustainability of our interventions: no third-party application to maintain, no additional monthly subscription, and no risk of vulnerability introduced by external dependencies.

Transparent explanations

Each technical intervention is documented and detailed in a structured deliverable. We specify the modified files (sections, snippets, assets), the technical justification for each change, and its measurable impact on performance metrics. Complementary recommendations, particularly those concerning server settings (Shopify CDN) or optimizations at the level of installed third-party applications, are explained and shared with your teams during the final presentation.

Send a strong signal to Google and your visitors: focus on Core Web Vitals

A high-performing store guarantees a smooth browsing experience for your visitors, thus maximizing your chances of converting them into buyers. Statistics are eloquent: internet users quickly abandon a page that takes too long to load. If your site doesn't meet their expectations, they will turn to the competition. By entrusting us with the technical optimization of your Shopify store, you eliminate the technical bottlenecks that slow down your page rendering.

Collection and product pages that load instantly are also a decisive advantage for your positioning in Google search results. Initial response times, measured by the TTFB metric, directly influence how the indexing robots will utilize the crawl budget allocated to you. The more responsive your Shopify infrastructure, the better your catalog will be indexed... and therefore your visibility in the SERPs.

A service in 4 key steps

Our Shopify optimizations are broken down into several key stages.

A videoconference call as part of a service

Technical Alignment

To get the most out of our intervention, we need to understand in detail the architecture and specificities of your Shopify installation. This first videoconference session allows us to grasp your store's history, your theme customizations, integrated third-party applications, identified speed issues, and your web performance ambitions.

Tracking Implementation

We place a tag on your site that collects performance data from your real users. This "RUM" data is used to precisely identify bottlenecks. Thanks to this data-driven approach, we operate with maximum visibility on your issues.

We deploy Lighthouse monitors on your key pages to provide you with a synthetic view of performance evolution. Launched every 8 hours, they allow us to put numbers on mobile and desktop gains. Practical for those who track Core Web Vitals metrics in a tool like PageSpeed Insights.

Shopify Optimization

Following an exhaustive technical analysis of your Shopify store, we apply performance corrections directly in your duplicated theme in preview. This intervention phase, carried out over 3 days, constitutes the core of our service: we optimize Liquid code, CSS, JavaScript, webfonts, images, and third-party application integrations to sustainably improve Core Web Vitals.

Intervention Report

We organize a videoconference presentation session to show you the results of our intervention. The summary document is presented to you with, for each deployed optimization, precise technical explanations and an overview of the measured impacts on performance indicators (LCP, CLS, or INP). This privileged exchange allows us to answer your questions and transmit best practices that will ensure the long-term performance of your Shopify store.

Consult the FAQ for details about the service.

Should we prioritize optimization or an audit?

Our web performance experts have the necessary technical skills to intervene directly on the most customized Shopify themes, safely. This approach proves particularly relevant if you do not have experienced in-house front-end teams.

If you already have internal technical resources or a Shopify partner who knows your project, an audit is an interesting alternative to turnkey optimization: rather than implementing the fixes ourselves, we provide your teams with a detailed operational action plan. We can also provide post-deployment support through technical acceptance testing, included in the audit service.

How much does Shopify site optimization cost?

This service is structured as a package including the initial technical alignment session, the technical intervention phase (3 full days), and the production and presentation of a detailed, illustrated report via videoconference.

To obtain a price proposal, please contact our account manager Marylise by email or phone. She will quickly send you a personalized quote corresponding to your specific needs.

What can (and cannot) be optimized on Shopify?

Shopify hosts your store itself: the server infrastructure and CDN are managed by the platform and offer excellent response times (TTFB), with no room for maneuver on our end.

The bulk of the optimization potential is therefore on the front-end side: theme Liquid code, JavaScript, CSS, images, webfonts, and especially third-party applications, often responsible for the majority of page weight. This is precisely where your Core Web Vitals are determined.
