Improve

Shopify performance based on what real customers experience

We combine field and laboratory data to find what delays loading, blocks interaction or shifts content. Work is prioritised by impact and risk, not by an isolated score.

Outcome

Faster and more stable critical templates with a clear before-and-after comparison.

Duration

Usually 3 to 8 weeks for a focused intervention.

Investment

Shopify Performance Fix from €2,500 to €4,000 plus VAT.

Direct answer

We review app scripts, theme JavaScript, Liquid, images, fonts and third parties. We implement improvements that can be validated without breaking functionality or measurement.

When intervention makes sense

Shopify performance

01

LCP, INP or CLS is poor on commercial templates.

02

Apps load scripts on pages where they are not used.

03

Navigation or add to cart responds slowly.

04

Lighthouse improvements do not match the real user experience.

What we do

Shopify performance based on what real customers experience

01

Baseline

We measure field data, templates, devices and journeys before changing code.

02

Storefront cost

We attribute weight and execution time to apps, scripts, Liquid, images, fonts and external services.

03

Prioritised implementation

We address blocking work and unnecessary loading, starting with the strongest impact-to-risk ratio.

04

Post-change validation

We compare laboratory and field data, test functionality and document possible regressions.

How it is verified

How it is verified

  • Baseline by template and device
  • Script and third-party inventory
  • Before-and-after comparison
  • Functional QA and maintenance recommendations

Limits

Core Web Vitals also depend on device, network, apps and third parties. We do not promise one universal score without reviewing those dependencies.
