# I Will Optimise Your Shopify Store Speed for Higher Scores

Every second your [Shopify store](https://zinnhub.com/zinns/optimise-shopify-site-speed-and-boost-performance-for-faster-loading-times/) takes to load costs you customers. Studies consistently show that slower pages lead directly to higher bounce rates, lower search rankings, and fewer completed purchases. If your store is slow, it is quietly working against you every single day — and that is exactly what this service is designed to fix.

Zinn Digital® is a London-based Shopify development and CRO specialist team with dedicated expertise in store performance optimisation. We take underperforming Shopify stores and systematically transform them into fast, smooth, conversion-ready experiences — without touching your design, products, or store content.

\*\*What the optimisation covers:\*\*

Our process is methodical and thorough. We begin by benchmarking your current scores across Google PageSpeed Insights and GTmetrix before any work begins, so you have a clear before-and-after picture. We then work through a comprehensive set of performance improvements including reducing HTTP requests, compressing and properly sizing images, implementing intelligent lazy loading, streamlining font loading, auditing and removing redundant app code, and minifying and combining JavaScript and CSS files.

Every change is made on a duplicate copy of your live theme — meaning your live store remains fully operational and visible to your customers and any running advertisements throughout the entire process. Once optimisation is complete and verified, we hand the improved theme back to you. A backup theme is also created for additional peace of mind.

\*\*What you can expect:\*\*

The entry package targets 65+ Mobile and 80+ Desktop on Google PageSpeed Insights, alongside a B Grade on GTmetrix. Upgrading unlocks progressively higher score targets, more revisions, and a broader scope of optimisation work — giving you flexibility depending on how competitive your niche is and how ambitious your performance goals are.

\*\*Important to know:\*\*

Score targets apply to standard Shopify themes. Stores using third-party page builders (such as Pagefly, GemPages, or Shogun) or custom-coded themes may require a bespoke approach — reach out via the order chat before purchasing and we will advise accordingly.

\*\*Who this is for:\*\*

This service is ideal for [Shopify store](https://zinnhub.com/zinns/boost-shopify-store-loading-speed-for-enhanced-performance/) owners who are losing potential customers to slow load times, struggling with poor Core Web Vitals, running paid traffic to an underperforming store, or simply wanting a faster, more professional shopping experience for their visitors.

After delivery, the Zinn Digital® team remains available to support you and answer any questions. Your store’s performance matters — let us help you get it right.
