FAQ
Shopify speed optimization questions answered.
A 1-second delay in page load time reduces conversions by 7%. Google's Core Web Vitals are a ranking factor. A slow Shopify store hurts both your conversion rate and your organic search rankings simultaneously. Speed optimization delivers compounding returns across revenue and SEO.
Most Shopify stores reach 85-95+ on mobile and 90-98 on desktop after our optimization. The achievable score depends on your theme, app count and content. We set realistic targets after the initial audit and deliver a written guarantee of minimum score improvement.
We audit every app's performance impact and recommend removal of apps that add significant load time without proportional business value. We always get your approval before removing any app and suggest lightweight alternatives where possible.
No. All changes are made and tested on a development copy of your store before being applied to production. Visual design is fully preserved. We test across Chrome, Safari, Firefox and at mobile breakpoints before any changes go live.
Core Web Vitals are Google's three key page experience metrics: LCP (Largest Contentful Paint - loading speed), CLS (Cumulative Layout Shift - visual stability) and INP (Interaction to Next Paint - interactivity). Google uses these as ranking signals. Stores that pass Core Web Vitals rank higher for equivalent keyword quality.
A standard Shopify speed optimization project takes 7-14 days depending on the complexity of your theme and the number of issues found. The initial audit takes 2 days, implementation 5-10 days and QA 2 days.
