About This Service

Shopify Speed Optimization & Core Web Vitals Service for UAE Stores

A slow Shopify store quietly bleeds revenue: Google's Core Web Vitals — LCP, INP and CLS — now shape both your search rankings and how many mobile visitors stay long enough to buy. Most UAE shoppers browse on 4G/5G phones during commutes in Dubai and Sharjah, and every extra second of load time on a product page measurably cuts add-to-cart rates. This service is a focused performance overhaul of your existing Shopify store: I audit every installed app and remove the bloat (orphaned script tags from uninstalled apps are the number-one Shopify speed killer), clean unused JavaScript and CSS out of the theme, eliminate render-blocking resources, and defer third-party scripts — pixels, chat widgets, review apps — so they stop competing with your product images for bandwidth.

Images get the full treatment too: correct sizing through Shopify's CDN, modern formats, native lazy loading below the fold, and a preloaded LCP hero so your main product image paints fast. You receive before-and-after Google PageSpeed Insights and Lighthouse reports for mobile and desktop, so the improvement is documented in numbers, not promises. For Dubai, Abu Dhabi and Sharjah merchants spending on Meta and Google ads in AED, faster landing pages also mean lower cost-per-acquisition — speed is the cheapest conversion-rate upgrade you can buy.

Note the difference from my other Shopify gigs on Nadbook: the OS 2.0 theme customization and private-app gigs add new features and functionality to your store. This gig does the opposite job — it strips the accumulated slowness out of the store you already have, without changing how it looks or works for your customers.

What's included

  • Full Core Web Vitals audit — LCP, INP and CLS measured on your top templates (home, collection, product, cart) before any change is made.
  • App bloat audit & removal — Every installed app reviewed; leftover scripts from deleted apps stripped from theme.liquid and snippets.
  • Theme code cleanup — Unused JS/CSS removed, render-blocking resources deferred or inlined, critical CSS prioritized.
  • Image optimization & lazy loading — Responsive image sizes via Shopify CDN, lazy loading below the fold, preloaded LCP hero image.
  • Third-party script management — Pixels, chat and review widgets deferred or loaded on interaction so they stop blocking first paint.
  • Before/after PageSpeed reports — Documented mobile and desktop Lighthouse scores proving the gain, delivered with the handover.

How it works

  1. 1
    Baseline audit

    I run PageSpeed Insights and Lighthouse on your key pages, profile the theme, and map every app's script footprint. You get a findings summary before I touch anything.

  2. 2
    Optimize on a duplicate theme

    All cleanup happens on a duplicated theme — your live store keeps selling. App leftovers, dead code, oversized images and blocking scripts are dealt with one by one.

  3. 3
    Verify & publish

    We compare before/after scores together, click-test checkout and key flows, then publish the optimized theme at a low-traffic hour.

  4. 4
    Report & prevention tips

    You receive the full report plus a short guide on which app habits will keep the store fast after I'm gone.
