Speed optimization (Core Web Vitals)
Faster pages on mobile, measured before and after: a Lighthouse audit first, then fixes for the images, scripts and apps that slow your store.
What's included
- A Lighthouse and Core Web Vitals baseline
- Fixes for LCP and layout shift
- Heavy apps and scripts deferred or removed
- Images and video served at the right size
- Measurements after each round of fixes
Sounds familiar?
- Your store loads slowly on mobile, and visitors leave before it does.
- Google Search Console flags your Core Web Vitals.
- Every app you add makes the store a little slower.

Questions
What results have you had?
Loma Lux's mobile home page went from 13.1 s to 3.1 s LCP, and Kidoriman's from 8.5 s to 3.4 s, both in lab tests.
Will I lose features?
Nothing is removed without your OK. Most gains come from loading things later or at the right size, not from cutting them.
Do you speed up WooCommerce and BigCommerce stores too?
Yes. For a US vape store chain I cut BigCommerce image weight by 81%, and a store I moved to WooCommerce serves cached pages in a fraction of a second.
