Speed and performance

The agency site treats page speed as a service, not a slogan. This is what we actually change.

Measure first​

Record Largest Contentful Paint and the page weight on the home page, a collection, and a product, on a phone profile. Do that before installing another app. An optimization project that starts with a new app usually gets slower.

The usual wins​

  • Theme. Fewer sections above the fold, images through Shopify's CDN at the size the layout uses, and no render-blocking marketing script in theme.liquid that could be an app embed loaded later.
  • Apps. Each app embed and checkout extension costs something. Uninstall the ones the store does not use. Our own apps are theme blocks and embeds for that reason: they can be removed without leftover snippets.
  • Images and video. Hero media is almost always the LCP element. Compress it and do not autoplay a full-width video on a phone unless you have measured it.

What "fast" means here​

xco.agency talks about sub-second pages and a 98/100 target after the work. Those are targets for a project we have measured. We do not stamp them on a store we have not audited.

If you want that audit, book a call.
