PageSpeed, Core Web Vitals, Performance

Website Speed Optimization

Our website speed optimization services improve how quickly your Shopify, BigCommerce, and other ecommerce sites load and respond without stripping away the storefront features your customers need.

Problems we solve

We fix the bottlenecks slowing your store down

01

Are slow pages making customers wait?

We review image delivery, scripts, styles, fonts, and server response to identify what delays the first useful content.

02

Are mobile interactions slow or unstable?

We investigate responsiveness and layout movement across priority mobile templates, including Core Web Vitals diagnostics.

03

Are apps and tracking scripts adding too much weight?

We review third-party tools and loading behavior so essential storefront features work without unnecessary early-loading code.

Our Services

What our website speed optimization service includes

Priority page templates

We test the homepage and the product, collection, article, and content templates that shape the experience across your site.

Core Web Vitals

We review loading, responsiveness, and visual stability through LCP, INP, CLS, and related PageSpeed diagnostics.

Images and media

We improve hero, product, collection, and content image loading with better sizing, priority, formats, and below-the-fold behavior.

JavaScript and main-thread work

We find duplicate, unused, or early-loading code and reduce work that blocks rendering or delays page interaction.

Apps and third-party scripts

We review analytics, search, cart, review, personalization, and marketing tools so non-critical behavior loads when it is actually needed.

CSS and font loading

We clean up duplicate styles, render-blocking assets, and font-loading issues that can delay the first useful paint.

Mobile performance

We treat mobile and desktop separately because slow LCP, blocking time, and layout movement often affect mobile shoppers more severely.

Server response and delivery

We review Time to First Byte, caching, redirects, asset delivery, and platform limitations that influence how quickly a page can start loading.

Testing and verification

We retest the same priority pages, compare multiple runs where practical, and document what improved and what still depends on the platform or apps.

Our Process

How we work with you

01

We benchmark the priority pages

We run mobile and desktop PageSpeed tests on representative templates, review Core Web Vitals and field data when available, and use Semrush to surface additional performance issues.

02

We prioritize safe, high-impact fixes

We separate theme and code opportunities from platform or app limitations, then scope the work by impact, effort, and risk to important storefront functionality.

03

We implement the improvements

We optimize image and font loading, reduce unnecessary scripts and styles, improve layout stability, and conditionally load assets across the pages that need them.

04

We retest and document the results

We compare before-and-after results across the tested page types and explain remaining constraints. Scores can fluctuate, so we focus on repeatable improvements instead of promising a fixed number.
