You have an outdated showcase website, a design that no longer reflects your brand image, and you're struggling to appear on Google. You know you need to act, but where do you start? Finding the right web agency to manage both the redesign and natural search engine optimization (SEO) is often where projects get complicated.
Good news: with the right criteria, this choice becomes much simpler.
Because a poorly managed redesign can cause your organic traffic to plummet by 15 to 50%. It's a classic mistake: commissioning a new website from one agency and entrusting SEO to another, or worse, ignoring it completely. Missing redirects, modified URLs without a migration plan, deleted meta tags... these are all technical details that, when combined, can cost months of visibility.
An agency that masters both dimensions from the start protects your existing SEO while building a solid foundation for future growth. This is, in fact, the founding principle of our approach website creation at Easyweb: design and SEO are a single project.
Even before contacting agencies, it's best to know what you expect. A successful redesign in 2026 generally includes:
Budget-wise, expect to pay between €3,000 and €8,000 (excl. VAT) for a professional showcase website built by an agency (source: Gemeos Agency, 2025). More complex projects, integrating advanced SEO or specific functionalities, may exceed this range.
Key takeaway
A redesign without an SEO migration plan is like starting from scratch on Google. 301 redirects, preserving strategic URLs, and a preliminary audit are not options; they are the foundations.
Four points allow you to quickly narrow down the choices:
1. It designs the website and manages SEO in-house
When design, development, and SEO are handled by the same team, technical decisions incorporate SEO from the wireframe stage. This prevents costly revisions after launch.
2. It presents you with concrete case studies
Ask for examples of redesigns similar to your industry or company size. A good portfolio should show before-and-after results, not just flattering screenshots. Ideally, the agency can share measurable outcomes: organic traffic growth, conversion rate improvements, and enhancements to Core Web Vitals.
3. It starts with an audit
A serious agency won't send a quote without first analyzing your existing website. A preliminary SEO audit helps identify your high-performing pages, technical weaknesses, and keyword opportunities to leverage. This forms the foundation of a coherent strategy, not just a sales gimmick. Our SEO/GEO service systematically includes this step before making any recommendations.
4. It speaks your language, not just code
A good provider can explain technical decisions to someone who isn't a developer. If communication is unclear, deadlines are never specified, or KPIs are vague, it's often a red flag. Transparency in the relationship is also a crucial selection criterion.
At Easyweb, the website and SEO are treated as a single project, not two parallel missions. As aweb agency based in France, every redesign project begins with a technical and editorial audit. This allows us to know precisely what to preserve, what to improve, and how to position the site on Google from the moment it goes live.
Our projects encompass both custom showcase websites and web and mobile applications iOS/Android. What this means for you: a single point of contact who manages the entire digital project, from design to visibility, with development that is either 100% hand-coded or CMS-based, depending on your needs.
If you want to compare available options based on your city or CMS, our web agency directory lists the best references on the market, including WordPress agencies in Lyon for projects using this CMS.
Here are direct questions that will give you valuable insights during your initial discussions:
An agency that clearly answers these questions has already managed this type of project. An agency that dodges them is already giving you an answer.
Key takeaway
These questions act as a filter: they distinguish agencies with real SEO migration experience from those who will discover problems once the site is live. Don't skip them, regardless of the announced budget or deadline.
Do things well, without exception. Redesigning your showcase website is a foundational decision for your business. Doing it with an agency that integrates SEO as a priority, rather than an additional service, is often the difference between a site that generates leads and one that languishes on Google.
You can estimate your project directly via our quote generator, or consult our free white papers to better define your needs before contacting an agency. An initial audit often helps structure the project much faster than you might think.
