Shopify Speed Optimization
Gencer Karakaya is a Shopify performance specialist who takes slow stores to a 95+ Core Web Vitals score. He audits the apps, scripts, and Liquid that drag down LCP, INP, and CLS, removes the dead weight, and rebuilds the critical rendering path. The first metric he measures is TTFB, because server and CDN response time sets the ceiling for LCP, and every page is held to a defined performance budget so a new app cannot quietly regress the score. Because he is a developer, the fixes go beyond plugin toggles: lazy loading, image optimization and font strategy, and theme refactors that hold up under real traffic.
What this includes
- Core Web Vitals audit (LCP, INP, CLS) plus TTFB, on real-device and Lighthouse lab data
- App and third-party script audit, removing or deferring what blocks rendering
- Image optimization, font, and critical-CSS strategy for fast first paint
- Liquid and JavaScript refactors to cut main-thread work
- Lazy loading, preloading, and resource-hint tuning
- A performance budget and ongoing monitoring so the score does not regress after new apps
Frequently asked questions
Why is my Shopify store slow?
Most slow Shopify stores are slowed by apps and third-party scripts, oversized images, and bloated theme code, not by Shopify itself. The fix is auditing what loads on each page in Lighthouse, removing or deferring what is not essential, and refactoring the theme's critical path. That is what takes Core Web Vitals back into the green.
Can you get my store to a 95+ Core Web Vitals score?
In most cases, yes. I keep every page I build at 95+ and routinely bring existing stores there by cutting render-blocking scripts, fixing the largest contentful paint, and reducing layout shift, without changing how the store looks to shoppers.
Will speed optimization break my apps?
No. I test each change against your store's functionality and only defer or remove scripts that are safe to defer or remove. Critical app behavior keeps working; what gets cut is the dead weight that was never needed on that page.
