"I tried three ‘experts’ before Page Speed Group, and none delivered like this. Their technical mastery of Shopify’s Core Web Vitals is insane. In 2023, they optimized our code and assets, boosting our Google mobile page speed score to an average of 95/100 (up from 12!). Looking at real user metrics our pages now load in 1.2 seconds, and we’ve seen a 44% spike in conversions from international traffic. They’ve added a couple hundred grand to our bottom line. Best investment we’ve ever made for our Shopify store!"

FAQS

Got Questions?

Everything You Need to Know

Do I need to uninstall apps from my Shopify store?

No, if an app is actively used and essential to your store, we’ll keep it!

During our optimization process, we’ll:

  1. Audit every app to identify its impact on your site’s speed.
  2. Work with you to confirm which apps are no longer in use.
  3. Strongly recommend uninstalling unused apps to eliminate performance-draining bloat.

Our goal? Keep what works, remove what doesn’t, and ensure your store stays fast without sacrificing functionality.

Do I need to be on Shopify Plus for you to optimize my store?

No, we optimize stores on any Shopify plan (Basic, Advanced, and Plus), except headless commerce setups.

Why it works for non-Plus plans:

  • Shopify’s core infrastructure (CDN, servers, theme architecture) is identical across all plans.
  • Our optimizations target your theme, apps, and assets, not Shopify’s backend.

⚠️ Exception: Headless Shopify stores (e.g., Hydrogen, custom React frontends) require a different technical approach. If you are headless, contact us HERE for custom offer.

Pro Tip: You don’t need Plus to hit 90+ PSI scores. Even Basic stores can outperform Plus sites with our optimization approach!

Why do you focus on real-user Core Web Vitals performance scores?

We focus on real-user Core Web Vitals (CWV) because they measure how actual visitors experience your Shopify store, not how a lab simulation does.

Here’s why that matters:

  • They reflect true user experience.
    Core Web Vitals (CWV) are field metrics derived from aggregated, anonymized performance data collected from opted-in Chrome users via the Chrome User Experience Report (CrUX), computed over a rolling 28-day measurement period, with performance assessed at the 75th percentile for each metric. CWV are showing how quickly your store loads, how stable it feels as users scroll, and how fast it reacts to their actions. In short, CWV tell you exactly what your customers are actually feeling, not what a test environment predicts.

  • They directly influence Google’s ranking systems.
    Google’s core ranking algorithms are designed to reward websites that deliver excellent user experiences. Strong Core Web Vitals performance, along with other page experience signals, can lead to better visibility, increased impressions, and more organic clicks.

⚡ Bottom line: Lab data helps us find and fix issues. But Core Web Vitals prove whether those fixes truly work for real users. That’s why CWV are our top priority, as they bridge the gap between technical optimization and tangible business results.

Do you still work on improving Lighthouse scores on Google PageSpeed Insights?

Absolutely! We still focus on achieving 90+ mobile scores on Google PageSpeed Insights (PSI), but we now treat those scores as a means to an end, not the end goal.

🔍 Understanding the role of Lighthouse (lab) data

The PSI score is based on Lighthouse lab data, a controlled test that simulates user behavior. While it doesn’t show real-world experience, it helps us pinpoint performance bottlenecks, things like render-blocking scripts, unused assets, or inefficient JavaScript execution before they impact your customers.

📊 Lab data complements field (real-user) data

Real User Monitoring (RUM) and Chrome User Experience Report (CrUX) data provide valuable insight into actual user behavior. However, these datasets take time to update and only include Chrome users. That’s where lab testing bridges the gap, by giving us immediate visibility into potential issues and ensuring proactive optimization.

🚀 Strategic synergy for lasting performance

When we push your PSI mobile score above 90, it’s not just to show a high number - it’s proof that every critical issue has been resolved. And when combined with strong Core Web Vitals results that we continue to optimize over time, your store achieves both exceptional measured speed and real-world user satisfaction.

In short, PSI (lab data) tells us where to improve, while Core Web Vitals (field data) confirm that users are actually benefiting. We optimize both because true performance means excelling in the lab and in the real world.

Why do you use an average Google PSI general performance score?

Google PageSpeed Insights (PSI) scores fluctuate due to variables outside your control, like server load, traffic spikes, or third-party app activity. A single test is a snapshot, not the full story.

During evaluation of your Shopify store, we run 9 tests daily (3 in the morning, 3 in the afternoon, 3 in the evening) to:

  1. Account for Shopify’s shared hosting environment: Server response times (TTFB) can vary based on platform-wide traffic.
  2. Unmask third-party app drag: Apps like live chat, reviews, or upsell tools often inject code inconsistently.
  3. Factor in global traffic patterns: Slowdowns from geo-specific CDNs (like Shopify’s) or payment gateways (e.g., Klarna, PayPal) won’t show in one test.

By averaging scores, we:

  • Eliminate outliers (like a one-time app glitch).
  • Pinpoint persistent issues (e.g., unoptimized theme code or oversized images).
  • Align with Core Web Vitals’ 75th percentile rule, which Google uses for rankings.

This method ensures your optimization targets real-world performance, not lab-perfect conditions.

Can you perform optimization on a Shopify website built with page builders?

Usually, no. Legacy page builders like GemPages, Zipify, Builder.io, and similar tools make meaningful optimization nearly impossible. Here’s why:

Legacy page builders host content on third-party servers and inject code outside Shopify’s native environment. This means:

  • 🚫 Zero control over critical resources: Images, scripts, and styling are loaded from the page builder’s server. We can’t optimize file sizes, lazy-load elements, or leverage proper caching.
  • 🚫 Third-party server bottlenecks: Speed hinges on their server response times (TTFB), not yours or Shopify’s. If their servers lag, your page lags, and we can’t fix that.
  • 🚫 Unavoidable code bloat: Page builders add layers of bulky scripts/CSS to enable drag-and-drop features. Removing this bloat would break your pages entirely.

Exception: Replo

Unlike legacy page builders, Replo does things differently. Once you finish your design, Replo generates native Shopify code (HTML, Liquid, CSS, JavaScript) and sends it directly into your store. No third-party servers, no external script loading, no waiting for someone else’s infrastructure.

✅ Full control: Since the content lives inside your Shopify store, we can optimize it just like we would any other part of your theme.

✅ No outside delays: Everything loads from Shopify, not from Replo’s servers. That means faster pages and no hidden bottlenecks.

So if you're using Replo, yes - we can fully optimize those pages.

I am using heat mapping or A/B testing software. Why are these possible bottlenecks for page speed?

Heatmaps and A/B testing tools (like Hotjar, Optimizely, or Lucky Orange) add third-party scripts that can slow down your Shopify store in 3 key ways:

  1. 🐌 Extra HTTP Requests: Each tool injects external scripts, forcing browsers to fetch more files. For example, Hotjar adds ~150KB of JavaScript, delaying page rendering.
  2. ⏳ Render-Blocking Code: Many tools load scripts before your page content, pushing back Core Web Vitals metrics like Largest Contentful Paint (LCP).
  3. 🎯 Uncached Resources: Scripts hosted on third-party servers (e.g., VWO’s servers) can’t leverage Shopify’s CDN, leading to slower load times for international visitors.

The good news? These tools are typically used short-term for testing. 

Once testing ends, we remove unused scripts, optimize remaining ones (deferring, lazy-loading), and clean up residual code bloat.

Pro Tip: Always audit and uninstall testing tools after A/B test campaigns as lingering scripts are silent speed killers.

Would you track our analytics?

Yes, tracking key metrics is critical to proving the ROI of speed optimization. Here’s what we monitor and why:

🚀 Core Metrics:

  1. Bounce Rate (Did faster pages keep visitors engaged?)
  2. Conversion Rate (Did speed gains turn more browsers into buyers?)
  3. Core Web Vitals (LCP, FID, CLS – Google’s official speed benchmarks).
  4. Mobile vs. Desktop Performance (Speed impacts these audiences differently).
  5. Revenue per Session (The ultimate bottom-line metric).

📈 Why We Need Access:

  • Google Analytics 4 (GA4): To analyze traffic behavior pre- and post-optimization.
  • Google Search Console: To identify technical SEO fixes (e.g., mobile usability errors, indexing issues) that align with speed improvements.

📅 What kind of reports we generate:

  1. Initial Report: We’ll document your current metrics before touching your store.
  2. Custom Updates: Depending on your subscription package we'll share progress on speed gains and their correlation to improved KPIs.
  3. Monthly Report: Highlight wins like “40% drop in bounce rate on mobile” or “22% higher conversions from returning visitors.”

Example: After optimizing a client’s Shopify store, we tied a 0.8-second LCP improvement to a 17% revenue increase in their GA4 data, proving speed’s direct impact on sales.

🔒 Your Privacy, Our Priority: Analytics access is used solely for performance tracking and insights. No data is used beyond that scope, and all access remains transparent and purpose-driven.

What is the difference between the solutions?

Speed optimization isn’t a “one-and-done” fix. It’s an ongoing battle against app bloat, code updates, and human error. That's why we carefully structured our plans to protect your store’s performance over time.

🚀 One-Time Optimization

  • Guaranteed average 90+ Mobile PSI score post-launch.
  • Best for static stores that won’t add apps or change content.
  • ⚠️ Warning: Speed gains degrade fast (e.g., new apps/images undo optimizations).

🛡️ Ongoing Maintenance

  • Choose your Monthly, Weekly or Daily (hourly) plan:
  • Ideal for growing stores: Locks in speed gains, neutralizes new threats (apps, code edits).

Why most clients choose Ongoing:
Shopify stores evolve and your speed shouldn’t regress.

Fact: 79% of active stores lose speed benefits within the first month without maintenance.

Not sure which plan fits?
➡️ 87% of stores with 250k+ monthly visitors choose Daily/24/7 to safeguard revenue.
