FAQ

Frequently asked questions about Shopify speed optimization

Clear answers to the questions merchants ask before they invest in speed and Core Web Vitals.

How long does a Shopify speed optimization project take?

The 48-hour Audit delivers a full performance report in just 2 business days. The 7-Day Optimization Sprint typically completes within a week, implementing real fixes to your theme and Core Web Vitals. For large or Shopify Plus stores, our Advanced Shopify Performance package is scheduled case-by-case but still designed to minimize downtime and get results quickly.

Will you break my theme or existing apps?

We work directly inside your current theme using backups and staging environments where possible. We avoid risky refactors and validate all changes with before/after tests to ensure layouts, analytics tracking, and apps keep working smoothly. Your store stays functional throughout the optimization process.

What kind of results can I realistically expect?

Based on recent projects, merchants typically see +20–40 points in Lighthouse/PageSpeed scores on key templates, 1.5–3 seconds faster perceived loading on mobile, 20–30% fewer drops from slow pages, and 30–60% less JS/CSS bloat. Actual results vary by your store's size, theme complexity, and app stack, but we'll estimate realistic impact during your 48-hour audit.

Do you only work with Shopify Plus stores?

No. We optimize both regular Shopify stores and Shopify Plus. Our Advanced Shopify Performance package is aimed at larger or more complex stores, but the 48-hour Audit and 7-Day Optimization Sprint work great for growing brands on standard Shopify plans too.

How much does Shopify speed optimization cost?

Our pricing is transparent and shown in the packages above: 48-hour Audit, 7-Day Optimization Sprint, and Advanced Shopify Performance. Each package is tailored to different store sizes and performance goals, so you can choose the scope that matches your needs and budget.

Can you help us after the initial optimization?

Yes. We can provide follow-up support to help your team implement audit recommendations, troubleshoot new issues, and optionally set up ongoing performance check-ins. This keeps your Core Web Vitals healthy as you add apps, sections, and launch new campaigns.
