I’m starting from scratch
You are setting up your business or have never had a website. The right order: a showcase website on the Core or Craft plan, your Google Business Profile at the same time, then local SEO once the site is live.

Web design, SEO and AI services for businesses in Lyon
Building a website that brings in customers, getting it found on Google, automating the tasks that eat up your time and keeping it compliant over the long term: our web agency services fall into six families, with published prices and results you can check project by project.
KAYZEN also develops its own digital tools in Lyon. Discover the eight applications.
KAYZEN is a web design and AI agency based in Lyon’s 9th arrondissement. We work with tradespeople, retailers, independent professionals and SMEs who expect more from a website than a digital business card: quote requests, bookings, sales, or hours of work handed back to their team.
The seventeen services below cover the whole chain — from audit to maintenance — and can be combined freely. One person follows your project from start to finish, our prices are published on this site, and every project is showcased with its measured scores. You don’t have to take our word for it: you can check.
Before you build
Strategy & consulting
A successful website starts before the first mock-up. We look at your market, your competitors in Lyon and the searches your customers actually type, then turn all of that into a costed roadmap: what needs doing, in what order, and what it should bring in. An audit works for an existing site too: it shows what is holding it back, what is costing you revenue and what can wait.
This is for you if
- You don’t know where to start, or what a reasonable budget looks like.
- You have a website, but it brings in neither enquiries nor calls.
- You need to choose between a redesign, a round of fixes and a replacement.
The foundation
Web solutions
Showcase websites, online shops and business applications are all built on the same foundation: lightweight code, pre-rendered pages that Google reads effortlessly, verified accessibility and go-live included. What sets them apart is what you need your site to deliver — enquiries, sales, or hours of work handed back to your team.
This is for you if
- Tradespeople, retailers, independent professionals and SMEs who want a website that generates leads.
- Brands that sell online without depending on a marketplace.
- Businesses with a repetitive task that deserves a dedicated tool or AI agent.
What your customers see
Design & branding
Design is not a decorative layer added at the end: it is what decides, within seconds, whether a visitor trusts you. We design clear interfaces, frictionless user journeys and brand identities that work as well on a shop sign as on a phone screen. Every choice is justified, and mock-ups are approved before a single line of code is written.
This is for you if
- Your website looks dated, or doesn’t reflect the quality of your work.
- You are launching a brand and need a logo, brand guidelines and a website that belong together.
- Visitors arrive on your site, but they don’t click.
Getting found
Visibility & SEO
A website nobody can find is of no use. Search engine optimisation is built into every site we make from the design stage, then worked on over time: page structure, content that answers your customers’ questions, loading speed, your Google listing, reviews. Across the projects whose measurements we publish, the average Lighthouse SEO score is 99/100 — and every score can be checked on the project’s page.
This is for you if
- Your competitors show up before you for “your trade + Lyon”.
- Your website is slow, or Google flags problems in Search Console.
- Your Google Business Profile is empty, with no photos or recent reviews.
Speeding things up
Digital marketing
While organic search takes time, online advertising and social media deliver immediate results — provided they are measured. We set up campaigns targeted at your catchment area, track every euro spent right through to the quote request, and cut whatever doesn’t pay off.
This is for you if
- You are opening, launching a seasonal offer or need to fill your diary quickly.
- You want to test a market before investing in content.
- You have an audience, but it isn’t turning into customers.
For the long term
Managed services
A website is a living thing: browsers change, legal requirements change too, and an unpatched vulnerability always ends up being expensive. We take care of maintenance, security, GDPR compliance and the accessibility required by the European Accessibility Act, in force since June 2025. Your website stays up to date, secure and compliant, without you having to think about it.
This is for you if
- You have nobody in-house to keep an eye on the website.
- You need to prove GDPR or accessibility compliance to a client, in a tender or during an inspection.
- Your website has already been hacked, or is showing security warnings.
Where to start
Three situations, three paths
Most of the enquiries we receive fall into one of these three cases. Find yours: what to read next is shown below.
My website brings in nothing
The website exists, it may even look good, but the phone doesn’t ring. Before rebuilding everything, an audit shows what is going wrong: slow loading, pages that can’t be found, confusing journeys. Often, three targeted fixes are worth as much as a redesign.
I want to save time
Quotes to write, enquiries to qualify, appointments to schedule, follow-ups to send: those hours can be handed back to your team. We identify the high-volume tasks and build the right agent or automation, connected to your tools.
Whatever the service
What is always included
A €1,599 showcase website and a business application don’t have the same scope. They do share the same standards.

Published prices

Frequently asked questions about our services
For a business that doesn’t have a website yet, a showcase website on the Core plan (from €1,599) covers the essentials: ten pages, responsive design, basic SEO and go-live with the hosting provider of your choice, SSL certificate included. If you already have a website but see few results, start with an audit: it costs less than a redesign and pinpoints exactly what is holding you back.
Our prices are public. A showcase website starts at €1,599 (Core), €2,499 (Craft) or €3,999 (Legacy, with e-commerce and advanced features). Maintenance costs €49 a month or €490 a year. Net prices — VAT not applicable, Article 293 B of the French CGI tax code. SEO and advertising have published prices; AI solutions are quoted according to the scope of the project. Every quote is free and sent within 24 hours.
A Core showcase website is delivered in 2 to 4 weeks, a Craft website in 4 to 6 weeks and a Legacy project in 6 to 10 weeks. These timescales include the brief, mock-ups, development, your feedback and final optimisation. An express service is available for a 15% surcharge.
Sometimes — and less often than online promises suggest. These schemes concern businesses established in France. In Auvergne-Rhône-Alpes, Atouts Numériques covers the diagnosis and support for businesses with fewer than 50 employees, and some local authorities offer local grants that vary. Details of the schemes that actually exist — and of those that no longer do — are kept up to date on our public funding page. We check your eligibility and help you put the application together; grants must be applied for before work begins.
No. We are based in Lyon’s 9th arrondissement and most of our clients are in Auvergne-Rhône-Alpes, but website design, SEO and above all AI solutions are delivered remotely for clients all over France. Meetings take place by video call or at our offices, whichever suits you.
Yes. Every website is delivered with hands-on training and a personalised guide: text, images, opening hours and contact details can be edited without us. For changes to the structure or design, the maintenance contract or a one-off job takes over.
Every project has its own page in the portfolio, with the context, the decisions made and the Lighthouse scores recorded — performance, accessibility, best practices and SEO. Across the 32 measured projects, the average SEO score is 99/100 and 28 sites score 100/100. Scores that could be better are shown too, with an explanation.
For 30 days, we monitor the website, fix whatever needs fixing and make adjustments based on your first feedback; this is included. After that, maintenance can take over if you wish: updates, backups, monitoring and a monthly report. You can also call on us for one-off jobs.
