PageSpeed Ninjas — Shopify Speed Optimization FAQs
Got Questions? We’ve Got Answers.
Find clear answers about our Shopify speed optimization services - including how it works, what to expect before and after purchase, and how we help you achieve higher Google PageSpeed Insights scores with zero downtime.
✅ Before You Purchase
Do I really need speed optimization?
If your Shopify store takes more than 3 seconds to load, you’re likely losing visitors, sales, and SEO visibility. Speed impacts everything from user experience to conversion rates - and slow stores rank lower on Google.
Our service is designed to fix that without breaking your theme or disrupting your live store. You can test your site now using Google PageSpeed Insights or GTmetrix - if your mobile score is under 65, you’ll definitely benefit from what we do.
What is Google PageSpeed Insights (PSI)?
PageSpeed optimization is the process of cleaning up your site’s code and assets to make it load faster and more efficiently.
This includes removing unused scripts, compressing images, lazy loading, deferring unnecessary code, and more — all to improve your scores and user experience.
What is GTmetrix Optimization?
GTMetrix is a tool we use to test your site’s real-world performance. It includes:
- Minimizing CSS and JavaScript files
- Lazy loading images and videos
- Optimizing fonts and assets
- Reducing unnecessary requests
- Addressing layout shift and rendering issues
Depending on your package, we’ll address issues GTmetrix identifies and make sure your store is optimized across all technical fronts.
Will I pass Core Web Vitals?
While we significantly improve performance through manual optimization, a perfect Core Web Vitals score (all “green” metrics) can’t be guaranteed.
This is mainly due to factors beyond our direct control such as third-party app scripts and some limitations within Shopify’s theme architecture.
That said, you can expect a measurable improvement in key metrics like Total Blocking Time (TBT) and Largest Contentful Paint (LCP), both of which strongly influence your Google PageSpeed and user experience scores.
Who is this service for?
We specialize in optimizing Shopify stores, especially for founders, marketers, developers, and agencies who want measurable performance improvements without risking their live site.

What is your refund policy?

For full details, please review our Refund Policy.
⚙️ During Optimization
What happens after I place an order?
Once you purchase a package, we’ll send you an email to confirm your store URL and send you a collaborator request. After that, we duplicate your live theme and begin optimization work on the copy, keeping your live store untouched until we’re done.
Do you work on the live store?
Never. We work on a duplicate theme to ensure your customers won’t be affected during optimization.
What’s your optimization process?
We follow a proven process tailored for Shopify:
- Audit your current performance
- Remove bloat and unused code
- Reconfigure or lazy-load heavy scripts
- Add async loading and deferral for non-critical scripts
- Optimize assets (like images, fonts, and animations)
- Test the optimized theme to hit your guaranteed PSI scores and GTmetrix
All of this is done on a duplicate theme so your live store stays untouched until you’re ready to go live.
How long does it take?
Most stores are completed in 3–5 business days, depending on the package and site complexity.
Will this affect the way my store looks or works?
Nope! All optimizations are made safely and carefully. We don’t remove anything critical or break functionality. Your store will look and work the same — just faster.
Will my apps still work?
Yes. We test functionality thoroughly to ensure your apps and features continue to work as expected after optimization. If anything breaks, we fix it.
Can I make changes to my site while you're working on it?
We recommend holding off on major edits (like new apps or theme changes) during the optimization process. Small things like updating products or publishing blogs are fine.
Also, we’ll be working on a duplicate version of your theme — so any changes you make to your live theme while we're optimizing won't carry over.
We'll let you know when everything's done and safe to update again.
Is my data safe?
Absolutely. We take your privacy seriously. We only request access to your Apps, Themes, and Blog Pages — just what we need to improve your site speed.
We do not ask for access to sensitive areas like your Store Settings, Orders, Products, or Customer data. Your information stays safe and secure the entire time.
🚀 After Optimization
How do I go live with the optimized theme?
We’ll guide you through publishing the optimized version.
What if something breaks after I go live?
We offer 7 days of post-launch support. If something breaks because of our work, we fix it - fast.
Why does my PageSpeed Insights (PSI) score fluctuate after optimization?
PSI scores can vary slightly depending on when and how the test is run. Google simulates performance using a range of connection types and device conditions, so scores may go up or down a few points.
This is totally normal - what matters most is that your store consistently loads faster and follows performance best practices. We test multiple times and optimize for stability, not just a one-time score.
What results can I expect?
You’ll see improved load times and higher PSI scores (we guarantee 65+ Mobile / 90+ Desktop). Many clients also report lower bounce rates and better conversion rates.
Will the optimization last forever?
The improvements we make are long-lasting as long as your theme and app setup stay the same.
However, if you make major changes like switching themes, adding new apps, or upgrading your theme version, it can affect your speed.
In that case, we recommend a fresh round of optimization to keep things running smoothly.
