E-Commerce Web Agency
An e-commerce site where every visit can turn into revenue.
An e-commerce site has to help people find, compare, choose, and buy without separating brand from performance. Gemeos structures the experience around the catalog, purchase intent, and the data that shows where the journey drops off or converts. Professional models overlap with some B2B challenges, while highly desirable brands need to preserve the codes of luxury all the way through transactional pages. On an e-commerce project, a web agency has to connect branding, UX/UI, SEO/GEO, tracking, and CRO to the platform choice and the real-world constraints of commerce.

What is your profile?
Expertise Tailored to Every E-Commerce Role
A high-performing e-commerce site starts with the catalog, margins, purchase journeys, and the friction points that actually shape conversion. The steps below connect architecture, UX, product content, SEO, data, tracking, and business tools to improve acquisition, basket size, and repeat purchases.
The Web Challenges Unique to E-Commerce
In e-commerce, performance is not decided only at checkout. The website needs to make an evolving catalog easy to explore, maintain a clean SEO architecture, reduce purchase friction, track journeys accurately, and make every product sufficiently clear for both search engines and generative engines.
Convert the catalog without compromising the checkout UX
Problem
A hard-to-read category, an incomplete product page, confusing variants, or weak internal search can break the journey before the item ever gets added to cart.
Solution
We map the decision journey by product type. Design prioritizes price, variants, availability, delivery, proof points, and help content, then connects those choices to the measurement plan.
Indicator
Product consultation, add to cart, search and filters, PDP-to-cart flow, conversion by category and on mobile.
Mastering the SEO Architecture of a Growing Catalog
Problem
Categories, filters, variants, out-of-stock products, and campaigns can generate thousands of low-value URLs. A poorly prepared migration can break pages that were driving visibility and revenue.
Solution
Our SEO/GEO approach defines which pages to create, index, and interlink before production. We handle taxonomy, facets, discontinued products, redirects, structured data, and content based on search intent.
Indicator
Non-brand clicks, useful indexed pages, crawl errors, SEO revenue, category visibility, post-migration losses.
Make the journey accessible without waiting for approval
Problem
Since June 28, 2025, e-commerce services covered by the European Accessibility Act have had to meet new requirements. In June 2026, the DGCCRF published its first review of its information and enforcement actions.
Solution
We build semantic structure, keyboard navigation, contrast ratios, labels, focus states, form errors, and clear, understandable content into every project. Gemeos doesn’t replace a legal audit; scope and any exceptions must be validated based on the company.
Indicator
Accessibility issues, keyboard coverage, form errors, checkout abandonment, fixes.
Measure Acquisition and Conversion Despite Consent and Multi-Device Journeys
Problem
An e-commerce business has to balance SEO, Ads, CRM, affiliate marketing, and retargeting based on data that’s sometimes incomplete. On January 16, 2026, the CNIL published a consolidated recommendation that includes multi-device consent.
Solution
We define product views, add-to-cart, checkout, purchase, promotions, forms, and the CRM events that matter. Our tracking expertise documents events, sources, and measurement limitations.
Indicator
Consent rate, attributed purchases, platform-to-analytics discrepancies, conversion by channel, missing events.
Make products understandable to search and generative engines
Problem
Product discovery is fragmenting across Google, Shopping, marketplaces, social media, and generative interfaces. Product pages reduced to a name, images, and supplier copy leave very little context.
Solution
We structure categories and products around clear attributes, useful comparisons, proof points, targeted FAQs, and tailored structured data. GEO makes the relationships between brand, product, use case, features, and audience easier to interpret.
Indicator
non-brand queries, attribute coverage, long-tail clicks, product visibility, generative mentions, organic conversion.
Details that make all the difference
What Gemeos Does That Competitors Don’t
A catalog organized by internal categories, not by customer intent or use cases.
We structure categories, products, and content around user intent, use cases, and business priorities.
Product pages focused on features, without addressing objections, proof, or comparisons.
Each product page connects benefits, proof, objections, and the information people need to make a decision.
Navigation and filters are designed before analyzing search and purchase behavior.
Navigation, filters, and internal search are structured around the catalog and real user journeys.
SEO is added after the catalog and product templates are in place.
SEO and GEO structure categories, products, and entities before templates.
CRO often focuses on a few CTAs without connecting merchandising, the cart, and trust signals.
CRO connects merchandising, reassurance, cart, and checkout steps to the friction we see.
Reporting tracks revenue and overall conversion, but doesn’t explain the gaps by journey.
Tracking analyzes acquisition, categories, products, cart behavior, and revenue to prioritize optimizations.

Most agencies make a great first impression and sell you the dream in those early conversations, but that illusion fades fast once the contract is signed. With Gemeos, it’s different. Gemeos are professional and genuinely committed to doing things right and fast. I really recommend them. And this is the first time I’ve ever recommended an agency.
Quentin Mayet
VP Marketing @Paradox
We worked with Gemeos in the summer of 2024 to redesign Modjo’s marketing site and better reflect the brand’s new positioning. The collaboration was incredibly efficient, the agency was highly responsive and adapted to every unexpected challenge. With limited resources on our side, right in the middle of summer, we launched the new site in just six weeks. Site visit engagement increased by 58%!

We entrusted Gemeos with a full website redesign and migration, and everything went incredibly smoothly. What stood out most to us was the quality of the art direction: a truly premium, cohesive visual direction, with a clear visual identity and highly polished choices throughout — typography, colors, iconography, pacing, hierarchy, and more. You can tell they have great taste, and above all, a real eye for detail on every screen. On top of that, the team is incredibly responsive and very experienced: they know both design and the technical side inside out. I’d recommend them without hesitation.
David BERNARD
CEO & Founder @AssessFirst
Sacha & Sandro worked on the redesign and migration of our website with a few clear goals: create a unique, differentiated visual identity, clarify our message and value proposition, smooth out the customer journey, and ultimately generate more business opportunities. We’re very happy with the result, and the numbers speak for themselves. Sacha & Sandro are skilled, committed, conscientious, passionate, and they see things through to the end. I highly recommend them!

Do you have any questions?
FAQ
What Is an E-Commerce Web Agency?
An e-commerce web agency supports the creation, redesign, or optimization of an online selling experience. Its scope can cover strategy, branding, UX/UI, catalog architecture, integration, SEO, tracking, and CRO.
Why Choose a Web Agency Specializing in E-Commerce?
Because an e-commerce site brings together catalog, transactions, acquisition, accessibility, tracking, and business tools. An agency that’s used to these constraints can handle taxonomy, UX, SEO/GEO, CRO, and platform selection within the same architecture, instead of optimizing design, traffic, and checkout separately.
Which Platform Should You Choose to Build an E-Commerce Website?
The right choice depends on your catalog, business rules, integrations, order volume, international needs, and the level of autonomy you expect. Shopify works well for many projects, while other setups may call for PrestaShop, a custom solution, or a headless architecture.
Is Webflow Suitable for E-Commerce?
Webflow can work well for simple catalogs, editorial experiences, landing pages, or brand layers. For more complex needs around payments, inventory, promotions, accounts, internationalization, or ERP, a dedicated e-commerce platform may be the better fit.
How Do You Successfully Redesign an E-Commerce Site for SEO?
We need to inventory the URLs that drive traffic and revenue, define the future taxonomy, manage facets and discontinued products, prepare redirects, preserve internal linking, and control indexing and structured data after launch.
How Do You Improve an Online Store's Conversion Rate?
First, identify where users drop off in the journey: listing, product page, cart, form, or checkout. Analytics, internal search, customer feedback, and testing help you form hypotheses and then measure the impact of changes.
Are E-Commerce Sites Affected by the New Accessibility Rules?
E-commerce services fall within the scope of the European Accessibility Directive, which has applied since June 28, 2025, with exceptions and conditions depending on the operator and the situation. Each company needs to check its own legal scope.
How Do You Optimize an E-Commerce Site for Generative Engines?
The priority is to provide reliable, well-structured product information: features, use cases, variants, compatibility, proof points, categories, and relationships between entities. GEO complements SEO. It doesn’t replace a strong catalog or brand authority.
Which KPIs Should You Track on an E-Commerce Site?
The most useful KPIs are usually conversion rate, revenue per visit, average order value, add-to-cart rate, checkout completion, mobile conversion, revenue by channel, non-brand SEO performance, and attribution quality.
How Much Does It Cost to Build or Redesign an E-Commerce Website?
The budget depends on catalog size, the platform, branding, ERP/PIM/CRM integrations, multilingual needs, SEO migration, accessibility, and tracking. The estimate has to follow the actual architecture.
