Online stores that close the sale.

Ecommerce website design is not decoration on top of a catalog. It is the set of decisions that determines whether a shopper finds the right product, believes the page, and finishes paying. Every store has three jobs: help people find, help them decide, and help them pay. A beautiful home page does almost none of that. Collections, product pages, cart and checkout do nearly all of it.

Unified Marketing has designed and built websites since 2006 for more than 1,100 businesses. Our team designed and built the WordPress and WooCommerce store for Marc Anthony True Professional, a hair care brand selling across the US and Canada, with collection banners, complete-your-look cross-sells, a salon section and style videos. Today we design stores in a clickable prototype through our website design process and build them by hand.

What each page in a store is for

The product page is where ecommerce website design earns its keep. A shopper landing from Google Shopping, a paid ad or an AI answer often never sees your home page. The product page has to introduce the brand, explain the product, prove it is worth the price, and close the sale on a phone screen. Here is the anatomy we design to, in roughly the order shoppers scan it.

Above the fold on mobile

• Product title and short benefit line that says what it is and who it is for.
• Price, with any sale or bundle logic stated plainly.
• Photos and video that show scale, texture and use, zoomable, with no layout shift as they load.
• Variant selectors for size, color or quantity that show stock status before the shopper picks.
• Add to cart as the single most visible button, sticky on mobile once the shopper scrolls.
• Delivery estimate and shipping cost or the free-shipping threshold, close to the button.
• Returns summary in one line, linked to the full policy.

Below the fold

• Details written for decisions: materials, dimensions, ingredients, compatibility, care.
• Size guides and fit notes where returns are usually about fit.
• Real customer reviews and photos, collected through an honest request flow.
• Product FAQs that answer the questions your support team hears most.
• Complete-the-set or frequently-bought-together suggestions that are genuinely related.
• Product structured data so search engines can read price, availability and reviews.

Test it yourself: open a product page on your phone and ask whether a stranger could buy with confidence without scrolling past the first screen and a half. If not, the design is leaving orders behind.

Our conversion leak audit walks through how we find the weak point on an existing product page. For new builds, the anatomy above becomes the template, and we fill it with real products in the prototype, not placeholder text.

Most carts are abandoned. Baymard Institute's cart abandonment research puts the documented average at 70.22 percent, calculated across 50 studies. Many of those shoppers were only browsing, but Baymard's survey of the rest shows that the biggest causes are design and policy decisions a store controls. Here is how we answer each one in ecommerce website design.

Platform rules shape how far checkout itself can change. On Shopify, standard checkout branding is available on Basic and up, while advanced changes to the information, shipping and payment steps require Shopify Plus, per Shopify's checkout help. That is why we do much of the checkout work earlier: on product pages and in the cart, where the store has full control.

Checkout checklist

1. Guest checkout on, with an optional account offer on the confirmation page.
2. Express payment buttons visible at the top of checkout and in the cart.
3. Total cost visible before the payment step, with no new fees added at the end.
4. Form fields cut to what fulfillment needs, with correct mobile keyboards for each field.
5. Error messages next to the field, written in plain language.
6. Order confirmation and emails that set delivery expectations and invite the next purchase, run with our email marketing team.

Good ecommerce website design depends on the right foundation. We build on Shopify and on WordPress with WooCommerce, and build custom web applications when a store needs logic neither platform handles well. The choice should follow your catalog, your team and your growth plan, not the agency's habit.

The performance and access bar

• Speed: Google's Core Web Vitals call a page good at Largest Contentful Paint of 2.5 seconds or less, Interaction to Next Paint of 200 milliseconds or less and Cumulative Layout Shift of 0.1 or less, at the 75th percentile. Heavy product images and late-loading widgets are the usual culprits.
• Accessibility: we design toward WCAG 2.2 AA. The Department of Justice says the ADA covers the online goods and services of businesses open to the public, per ADA.gov.
• Product data: Google's product data specification requires an ID, title, description, link, image link, price and availability for Merchant Center, and recommends a valid GTIN when one exists. We design the admin so that data gets filled in.
• Structured data: merchant listing markup on product pages, which Google's product structured data guide says works alongside Merchant Center feeds to improve eligibility.

Search and ads then build on the design. Our SEO team handles collections, internal links and content, AI SEO makes buying guides easy for AI answers to cite, and stores with a showroom should read how to rank higher on Google Maps.

Ecommerce website design timelines depend most on catalog size and product data quality. A store with clean data and ready photography moves fast. A store migrating thousands of products with inconsistent attributes spends more time on data than on design. Here is the typical shape.

Questions to ask any ecommerce design agency

1. Will we see our real products in the prototype, on mobile, before development?
2. How do you design shipping, delivery and returns information into product pages?
3. What platform would you recommend for our catalog, and what would make you change your mind?
4. How will product data, Merchant Center and product schema be handled?
5. Which apps or plugins will the store need, and what do they cost in speed?
6. How will we measure whether the new design sells more?

Red flags

• Mockups of the home page only, with product and checkout pages left to a template.
• No mention of mobile, where most store traffic arrives.
• Fake urgency timers and invented scarcity used as conversion tactics.
• A migration plan with no redirect map.
• No analytics or ecommerce tracking in scope.

Every store we build reports orders, leads and revenue by source in UnifiedIQ. Our team's national brand experience includes the Marc Anthony store and the US media campaign for Nu Skin's ageLOC system, and Joe Sale Photography sells fine-art prints from a custom theme with 50 SEO landing pages, every one scoring 99 to 100.
