Frequently Asked Questions
- How much does Shopify speed optimisation cost?
- A performance audit with fixes typically costs $2,000–$8,000 as a one-off project. Some agencies offer ongoing performance retainers for $1,000–$3,000/month to keep your store fast as you add products, apps, and content over time.
- Why is my Shopify store slow?
- The most common culprits are: too many Shopify apps (each one adds JavaScript), unoptimised images, bloated theme code, third-party tracking scripts, and render-blocking CSS. A performance agency will audit your store and identify exactly what's slowing it down.
- What's a good page speed score for a Shopify store?
- Aim for a Lighthouse performance score of 60+ on mobile (80+ on desktop). Perfect 100 scores aren't realistic for ecommerce stores with dynamic content and third-party scripts. Focus on Core Web Vitals (LCP, INP, CLS) passing thresholds rather than chasing a perfect number.
