Speed Optimization Services
A systematic approach to every performance bottleneck — from server response time to render-blocking JavaScript.
📊 Core Web Vitals Audit
Comprehensive LCP, CLS, and INP analysis with waterfall charts, field data from CrUX, and a prioritized fix list.
⚡ LCP Optimization
Hero image preloading, render-blocking resource elimination, font display swap, and server response time reduction.
📐 CLS Fixes
Explicit image dimensions, font fallback matching, late-loading banner elimination, and layout shift root cause analysis.
🔌 App Script Audit
We audit every installed app’s JavaScript impact, recommend removals, and defer or conditionally load remaining scripts.
🖼️ Image Pipeline (WebP/Lazy)
Shopify CDN WebP serving, responsive srcset attributes, lazy loading for below-fold images, and hero image preload hints.
🎨 Critical CSS & Liquid Refactor
Above-the-fold critical CSS inlined, unused CSS purged, and Liquid loops refactored to reduce render and API overhead.
Our Optimization Process
Audit before we touch a single file — every fix is data-driven and measured before and after.
1. Baseline Audit
We run PageSpeed Insights, WebPageTest, and Chrome DevTools to capture baseline scores and identify all bottlenecks.
2. Fix Plan & Prioritize
Fixes are ranked by impact vs. effort. You approve the plan before any code changes are made to your theme.
3. Implement Fixes
All changes are made in a theme duplicate. No live store disruption. Image pipeline, CSS, JS, and Liquid fixes applied.
4. Verify & Report
Post-fix scores documented, A/B compared against baseline, and a full performance report delivered with next steps.
WPDEV Optimization vs. DIY Speed Fixes
Why systematic optimization outperforms generic Shopify speed tips.
| Feature | WPDEV Optimization | DIY / Generic Tips |
|---|---|---|
| Data-driven audit first | ✓ CrUX + lab data | ✗ Guesswork |
| App script impact analysis | ✓ Every app assessed | ✗ Rarely done |
| Critical CSS generation | ✓ Above-fold only | ✗ Not standard |
| Liquid refactoring | ✓ Included | ✗ Skipped |
| Before/after measurement | ✓ Full report | ✗ Self-reported |
| No theme rebuild required | ✓ Works on any theme | ✗ Often suggests rebuild |
Frequently Asked Questions
Straight answers to the most common Shopify speed questions.
How do I improve my Shopify store speed?
App bloat is the one thing that consistently surprises store owners when we run the first audit. Most stores have 15–25 installed apps, but 30–40% of those are loading JavaScript on every page — including pages where they do nothing useful. That’s always the first place we cut. Once the app audit is done, image optimization (WebP, lazy loading, explicit dimensions) and critical CSS inlining are the next two highest-leverage fixes. Third-party script deferral and Liquid loop refactoring round out the full picture — but honestly, the app audit alone often moves stores from a 45 PageSpeed score to 65+ before we’ve touched a single line of theme code.
What is a good PageSpeed score for Shopify?
A good PageSpeed Insights score for Shopify is 70+ on mobile and 85+ on desktop. Scores above 80 on mobile are excellent and achievable with thorough optimization. Aiming for 90+ on desktop is realistic. Mobile scores matter most for Google’s ranking algorithms — prioritize mobile LCP and CLS above all other metrics.
Why is my Shopify store so slow?
The most common causes of a slow Shopify store are: too many installed apps (each loads JavaScript on every page even if unused on that page), large unoptimized images served as PNG or JPEG instead of WebP, render-blocking third-party scripts (live chat, review widgets, cookie banners), and Liquid template loops making excessive Storefront API calls.
How much does Shopify speed optimization cost?
A focused Shopify Core Web Vitals audit and fix package starts at $800–$1,500. A comprehensive optimization project covering images, app scripts, Liquid refactoring, critical CSS, and third-party script management runs $2,000–$4,000. We always start with a free speed audit so you know exactly what will be fixed before you pay anything.
