Websites, Shopify stores and web apps built to sell.

The brand, the website, the Shopify store or the web app, built to load fast, rank cleanly and move people from a search or ad click to an enquiry or a checkout, each with its tracking and follow-up built in.

What is a conversion-first ecommerce build?

A conversion-first website is designed around one commercial outcome rather than around visual style. Every page has a clear next step, a fast load, structured SEO markup and analytics wired in from day one, so traffic from search or paid ads becomes measurable enquiries, bookings or sales.

Best for

Ecommerce brands on Shopify that need a store built to sell from day one
Service businesses whose current site gets traffic but very few enquiries
Companies replacing a slow, dated or template WordPress site
Teams that want to edit their own content without breaking the design

What a build includes

Design and build

A custom design system for your brand. Built responsive from the smallest breakpoint up, so mobile is the primary experience rather than an afterthought.

Conversion architecture

Page structure, hierarchy and calls to action mapped to how your buyers actually decide. One clear next step per page instead of five competing ones.

Speed and Core Web Vitals

Image optimisation, deferred third-party scripts, code splitting and lazy loading. Fast pages rank better and lose fewer visitors before the content appears.

SEO foundations

Semantic markup, metadata, schema, clean URL structure, XML sitemap and internal linking built in during the build rather than retrofitted afterwards.

CMS your team can use

Sanity or Shopify set up so your team edits content safely. Structured fields instead of a free-form page builder that drifts away from the design.

Tracking from day one

GA4, Google Tag Manager and server-side conversion tracking configured at launch, so you can attribute results from the first visitor onward.

How we deliver it

Scope and intake We start by mapping your offer, your buyers and the single action each page has to drive. You get a range until we have seen your data (read-only), then one fixed price and a locked scope.
Structure and design Sitemap and page structure come first, then the visual design layers on top. Deciding structure early is what stops a build from turning into an expensive redesign three weeks in, when everything is harder to move.
Build and integrate We build the front end, wire up the CMS, forms, tracking and any third-party tools, then you review it all in a live staging environment. Real clicks on real pages, not static screenshots you have to imagine working.
Launch and measure We deploy, confirm every tracking event fires and submit the site to Search Console. For 14 days after launch we fix any bug caused by our own changes at no charge, so go-live starts the relationship.

What a web design agency builds, and how to choose one.

What does a web design agency do?

A web design agency plans, designs and builds a website around one commercial job: enquiries for a service business, orders for a store, signups for a product. The work covers the sitemap, the design, the front-end code, the content system, speed, search structure and tracking, then the launch and the fixes that follow it.

Three kinds of company use the label. Design studios deliver mockups and hand the code to someone else. Template shops install a theme and swap the logo and the colours. Build agencies own the chain from sitemap to tracking QA and stay accountable for the result. Proof of Pixel is the third kind.

Proof of Pixel is a marketing and consulting agency for businesses that live on enquiries and orders, building the website, the tracking and the follow-up as one system, with offices in Dubai, New York, London, Antwerp and Kuala Lumpur.

Shopify web design: what a store needs to sell

Shopify web design is the design and build of a store on Shopify: theme architecture, product and collection pages, checkout configuration, the apps that extend it, page speed, and the tracking that shows which channel sold what. A store needs all of those working together before paid traffic or email flows can pay back.

The product page is the sales page, so it gets the most design time: images that load fast, a price and a buy button visible without scrolling on a phone, reviews, and delivery and returns answered on the page. Speed is a sales variable. Deloitte's 2020 study with Google, Milliseconds Make Millions, measured a 0.1 second improvement in mobile site speed across 37 brands and found retail conversions rose 8.4%. Google's 2016 mobile speed research found that 53% of mobile visits are abandoned when a page takes longer than three seconds to load.

What does a Shopify development agency do?

A Shopify development agency writes the code a theme editor cannot produce: custom sections and templates in Liquid, headless storefronts, app and ERP integrations, catalogue migrations from WooCommerce or Magento, checkout extensions and speed work. It is the difference between configuring a store and building one around how the business sells.

Typical jobs a development agency takes on:

Custom theme sections and templates, built in Liquid so your team edits them without a developer
Migration of products, customers and orders from WooCommerce, Magento or a legacy platform, with URL redirects mapped
Integrations with Klaviyo, stock systems, ERPs, subscription apps and marketplaces
Speed work: image pipeline, app script audit, theme code cleanup and Core Web Vitals
Checkout extensions, B2B pricing, multi-currency and multi-language setup
Tracking: Meta pixel and Conversions API, GA4 and Google Tag Manager, run server-side through Stape

How much does a website cost?

The cost of a website is driven by page count, custom functionality, integrations, content migration and how much design work the brand needs. A five-page service site and a Shopify store with four hundred products and a loyalty integration are different projects, and the number is set once the scope is written down.

Five things move the number. The number of unique page templates, since a template is designed once and reused. Custom functionality such as calculators, booking, member areas or product configurators. Integrations with a CRM, an email platform, a payment or stock system. Content: who writes it, how much migrates, how many languages. And the state of the current site, because a rebuild with 600 URLs to redirect costs more than a clean start.

How is a website built, step by step?

A website build runs in six steps: scope, structure, design, build, staging review and launch. Structure comes before any visual design, because moving a page in a sitemap takes minutes and moving it three weeks into a build takes days. Most builds launch within three to six weeks, depending on page count and integrations.

On rebuilds we see the same pattern: the old site's rankings sit on a handful of URLs nobody on the team remembers, and those are the pages a redesign drops first. The URL audit in step two exists for that reason. It is how Life Experts got a "Trilingual website for an FSMA-regulated insurance broker, rebuilt without losing a single old URL", and how Pristine Smile got a "Dental practice website built end to end, PageSpeed 98 on mobile".

Map the offer, the buyers and the one action each page has to drive, then lock the scope.
Write the sitemap and wireframes, and audit the old site's URLs, rankings and traffic so nothing that performs gets lost.
Design the system: type, colour, components and page templates, mobile first.
Build the front end, then wire the CMS, forms, integrations and tracking.
Review every page on a live staging site, with real clicks and real forms.
Launch, confirm every tracking event fires and submit the site to Search Console.

Frequently asked questions

Do I own the website and the code?

Yes, the domain, hosting accounts, CMS and content are in your name from day one, and all source files and code are yours in full once the project is paid. You keep everything whether or not we keep working together.

Can I edit the website myself?

Yes, we set up Sanity or Shopify so your team can update text, images, blog posts and products without touching code. We include a short handover walkthrough at launch.

Do you build on WordPress, Webflow or Wix?

We do no new builds on WordPress, Webflow or Wix: we take on existing WordPress sites for rescues and rebuilds, because many good businesses run on one, and we never start a new site on WordPress, Webflow, Wix, Squarespace or a page builder. New sites are built by hand in React, Next.js or Vite with Sanity CMS, and stores on Shopify.

Should my store be on Shopify or WooCommerce?

New stores go on Shopify: hosted, a fast checkout, a deep app ecosystem and native Klaviyo and Meta integrations. An existing WooCommerce store that works stays on WooCommerce, since a migration costs money and risks rankings, and we build on it as it is.

Do you build web apps as well as websites?

Yes, alongside marketing sites and stores we build the product itself: customer portals, dashboards, SaaS front ends and internal tools, in React and Next.js on Supabase, Cloudflare or Vercel. Heed.Finance and VOIX on the work page were built that way, from MVP to product.
