Frequently Asked Questions
Most Shopify stores see a 40 to 70% improvement in load time and a 30 to 60-point jump in Google PageSpeed scores. The exact gain depends on your starting point, theme, apps, and image weight, which we benchmark in a free audit.
No. We work on a staging or development store first, test every change thoroughly, and only push optimizations live once they are fully validated. Your design, functionality, and apps remain intact.
A standard speed optimization project takes 1 to 3 weeks. Enterprise Shopify Plus stores or stores with deep app stacks may take 3 to 6 weeks for complete optimization.
Yes, significantly. Google uses Core Web Vitals (LCP, CLS, INP) as a direct ranking factor. Faster stores rank higher, get more organic traffic, and convert at higher rates than slower competitors.
Absolutely. Mobile shoppers are the most impatient. Studies show a 1-second mobile speed improvement can lift conversions by up to 27%. Our mobile-first optimization typically delivers a measurable lift within weeks.
Sometimes. Apps are one of the biggest causes of slow Shopify stores. We audit every app, remove bloat from unused ones, and optimize how essential apps load (deferring, lazy-loading, or replacing them with native code).
Yes. Speed degrades over time as you add apps, products, and content. Our ongoing monitoring plans catch regressions early and keep your store consistently fast month after month.
