Improve speed without guessing

This service is for Shopify stores affected by heavy scripts, oversized media, theme complexity or inconsistent page behavior. We use measurement to prioritize changes with the clearest customer and operational value.

Typical deliverables

  • Template and third-party script audit
  • Core Web Vitals review
  • Image, font and asset recommendations
  • Liquid, CSS and JavaScript improvements
  • Before-and-after testing notes

How the work moves

We measure representative pages, identify bottlenecks, rank opportunities by impact and risk, and test changes in a duplicate theme. Results are documented rather than presented as guaranteed scores.

What we need from you

Provide theme access, analytics context, priority templates and approval before removing or changing third-party tools.

Quality and ongoing support

Performance changes are checked against functionality, accessibility and visual stability. Continued monitoring can help identify regressions as apps and content change.

Frequently asked questions

Can you guarantee a Lighthouse score?

No. Scores vary by page, device, network and third-party services.

Will apps be removed?

Only with merchant approval after reviewing their business purpose and alternatives.
