A website redesign can affect far more than visual presentation. Structure, page speed, mobile usability, content hierarchy, and technical implementation all influence how easily users and search engines can understand a site. The companies below combine web design or development with SEO capabilities, making them relevant for businesses that want design and organic visibility handled as connected parts of the same project.

Gilzor combines web design with broader product development, covering UX/UI, responsive interfaces, frontend engineering, and custom web development.

Gilzor also addresses SEO-related considerations around website structure, performance, content presentation, and search-ready builds, making it relevant for companies that need design connected with technical execution. The company has European offices in Warsaw and Limassol.

KOTA is a London creative digital agency combining brand strategy, web design, development, content, SEO, and GEO. Search considerations enter projects at the planning stage through content audits, site architecture, keyword research, internal linking, migration planning, and technical optimization. The agency also provides ongoing SEO after launch, which makes it a stronger fit for businesses seeking both a distinctive visual identity and continued organic growth rather than a one-time website build.

Embryo is a Manchester digital marketing agency whose website team works directly with its search specialists. Web projects cover UX/UI, design, development, site structure, responsive performance, and conversion considerations, while the SEO team works across technical SEO, content, links, and organic strategy.

Nopio combines branding, design, development, content, and SEO through a single delivery team.

Net-devs is an enterprise software engineering company based in Warsaw. Its core capabilities include modern frontend development with React, Angular, Vue, and TypeScript, along with backend engineering, cloud architecture, discovery, prototyping, testing, and deployment.

SoftPro is a Warsaw software development company working across custom web applications, frontend engineering, cloud development, and ecommerce-related systems. Its published work includes a social commerce platform for product promotion, while its web development capabilities span responsive applications, React, Node.js, .NET, Azure, and other technologies used for custom customer-facing systems.
SoftPro is more relevant to custom commerce projects than to businesses simply looking for a preconfigured Shopify template. Its engineering model can support ecommerce websites that require custom workflows, integrations, cloud infrastructure, or commerce features embedded within a broader software product.

Mobian Studio is a Tallinn-based European software development company working on end-to-end digital product development, including wireframing, backend systems, APIs, cloud infrastructure, QA, and post-launch support. Its broader offering is centered more on product engineering than on ecommerce platforms specifically.
Published ecommerce listings associate Mobian with ecommerce software development and Shopify-related support. For ecommerce buyers, that makes the company more relevant where store functionality is part of a wider custom software requirement rather than a conventional design-only engagement.
The right web design and SEO company should be able to connect visual design, technical performance, site structure, and search visibility rather than treating them as separate tasks. For European businesses, that may mean choosing a partner with strong UX and development capabilities, a dedicated SEO team, or experience managing redesigns without sacrificing existing rankings.
The companies in this list offer different combinations of web design, development, technical SEO, content optimization, and ongoing digital marketing. The best fit depends on the complexity of the website, target markets, internal resources, and whether SEO support is needed only during the build or as a long-term growth channel.
