What affects Shopify speed the most?

The most common issues are unoptimized images, too many app scripts, render-blocking JavaScript, heavy fonts, unused theme code and late-loading media that causes layout shift.

Can you improve speed without rebuilding the store?

Often yes. Many stores can be improved through image, script, app and theme optimization. If the theme is fundamentally slow, we will explain when a rebuild is the better option.

Will speed optimization break apps or tracking?

We test carefully before removing or deferring scripts. Tracking, pixels and business-critical apps are handled with more caution than cosmetic widgets.

Do you guarantee a 100 PageSpeed score?

No serious agency should guarantee 100 for every Shopify store because apps, tracking, theme constraints and third-party scripts affect the score. We focus on real Core Web Vitals and measurable speed improvements.
