What You'll Receive
Full Description
Every second your Shopify store takes to load, you lose visitors, rankings, and revenue. This service delivers professional, hands-on Shopify speed optimisation — no plugins doing the heavy lifting, no automated shortcuts — just clean, manual, code-level improvements that produce measurable results.
After optimisation, you can expect Google PageSpeed Insights scores of Mobile 60–70 and Desktop 90+ at the entry level, rising to Desktop 95+ with image resising and full CSS/JS minification on higher tiers. GTmetrix grades improve accordingly. Core Web Vitals — including LCP, INP, and CLS — are addressed directly, so your store earns better signals in Google's ranking algorithm over time.
**What is included across all tiers:**
Every order includes manual speed optimisation and browser caching configuration. Higher tiers add photo resising and compression, CSS/JS minification, deferred and async JavaScript loading, lazy loading for images and videos, and cleanup of unused app scripts and theme code bloat.
All work is carried out on your live store without any downtime or disruption. Your design, layout, and functionality remain completely untouched — only the performance layer improves.
You also receive a performance report with practical tips to maintain your results long-term, plus 30 days of post-delivery support so you are never left on your own after the work is done.
**How it works:**
1. Place your order and provide your Shopify store URL and collaborator access.
2. The store is analysed using Google PageSpeed Insights and GTmetrix.
3. Manual optimisations are applied to the theme code.
4. Delivery is completed — typically within 24 hours of receiving access.
5. A performance report is shared, and 30-day support begins.
**Who is this for?**
This service is ideal for Shopify store owners who are frustrated by slow load times, struggling with poor Google rankings, or seeing high bounce rates. It suits stores of any size — from brand-new launches to established shops with heavy theme customisation.
Zinn Digital is based in London, England, and brings a software engineering background to every optimisation. The approach is technical, precise, and built around results that last — not just numbers on a test tool, but a genuinely faster store that converts more visitors into customers.

Frequently Asked Questions
Just two things: your Shopify store URL and collaborator or partner access to your store. Once received, optimisation begins immediately. If anything else is needed, you will be contacted via the order chat.
No. All optimisations are made to the performance layer of your theme code only. Your store's design, layout, product pages, and all features remain completely untouched — just faster and smoother.
Absolutely. The optimisation process is carried out on live stores without any downtime or disruption. Your store stays online, stable, and fully functional throughout.
You will see improvements in lab-based tools like Google PageSpeed Insights and GTmetrix immediately after delivery. The Shopify dashboard speed score and Core Web Vitals in Google Search Console update over time, as they use 28–30 days of real-user data. The faster store is live straight away — the reported scores catch up as traffic builds.
Yes. The optimisation directly targets LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and INP (Interaction to Next Paint) — the three metrics Google uses in its Core Web Vitals assessment. Improvements in these signals can positively influence your organic search rankings over time.
Most stores are fully optimised within 24 hours of receiving access. More complex stores with heavy customisation may take slightly longer, but delivery is always on time. If you need it faster, add the Extra Fast Delivery option at checkout.
All packages include post-delivery support — 15 days on the Basic tier and 30 days on Boost and Premium. During this period, any issues related to the optimised theme are resolved at no extra charge.
If you need a quick, solid performance improvement and your images are already well-sized, Basic is a strong starting point. If your store has large product images, choose Boost Upgrade. For stores with heavy app usage, lots of custom scripts, or ambitious PageSpeed targets, Premium Optimisation covers everything.
