Professional website development: your best salesperson works 24/7

Your website is often the first contact between your company and your future customers. Within a few seconds, it inspires trust — or drives people away. Exoa designs professional websites built for three things: strengthening your brand's credibility, being found on Google and turning visitors into customers. With a structured process, contractual deadlines and written guarantees.

What makes a website truly professional

A professional website is not about "looking nice". Four pillars make the difference between an online business card and a tool that generates revenue.

A design that inspires trust

75% of internet users judge a company's credibility by the design of its website. Consistent visual identity, clear hierarchy, quality photos: every detail works for your brand image.

SEO built in from the design stage

A beautiful site that's invisible on Google is useless. Semantic structure, loading speed, optimised tags, internal linking: SEO is not an option added afterwards, it is built into the foundations.

Security and GDPR compliance

SSL certificate, compliant forms, cookie management, legal notices: compliance protects your visitors and your business. Essential for European markets, including Luxembourg and its CNPD.

Measurable performance

A professional website is managed by results: traffic, enquiries, sales. We install the measurement tools from day one and deliver a fast site, with Core Web Vitals in the green on mobile.

Showcase, e-commerce or custom: three answers to three needs

The right choice depends on your business model, not on the technology in fashion. Here is how we guide you.

Our agency process in 5 steps

A successful web project is a well-scoped one. Each step has its deliverables, its approvals and its deadlines — you always know where your website stands.

STEP 01

Discovery and scoping

Goals, target audience, competition, existing content. Deliverable: specifications and a detailed quote within 48h.

STEP 02

Design mockups

Design of the homepage and key templates, true to your identity. Two revision cycles included.

STEP 03

Development

Responsive integration, features, SEO and speed optimisation. Progress tracked on an accessible staging site.

STEP 04

Acceptance testing and content

Multi-browser and mobile testing, final content integration, GDPR compliance, final fixes.

STEP 05

Launch and follow-up

Go-live, Google indexing, training on the tool and support included for 30 days.

Website builder, freelancer or agency: let's be honest

Each option has its place. Here is when an agency is the right choice — and when it is not.

Wix, AI & co

For testing, not for lasting

Perfect for validating an idea at minimal cost. But generic design, restricted SEO, no ownership of the site — and 40 to 100 hours of your time. As soon as the site needs to generate clients, the limit is quickly reached.

Freelaunches

A good choice, if chosen well

A senior freelancer builds excellent showcase sites. The risks: availability, continuity if they stop, and a scope limited to a single skill (design or dev or SEO, rarely all three).

Agency

When the website is strategic

A multidisciplinary team (design, development, SEO, content), contractual guarantees, long-term maintenance. The right choice when your website must produce measurable results, not just exist.

Our commitments, in black and white

Because a quote is not an empty promise, every Exoa project comes with written guarantees.

Contractual deadlines

The schedule is milestoned in the quote: mockup, development, acceptance testing, launch. Each milestone has a date, and you are kept informed at every step.

Revisions included

Two revision cycles on the mockups and one on the developed site are included in the price. No surprise surcharge at the first comment.

Full ownership

Domain, hosting, code, content: everything is in your name. You are free to leave at any time — our clients stay by choice, not because they're locked in.

30 days of support included

After launch, we stay available for a full month for any adjustment, fix or question. Then maintenance takes over if you wish.

On-page SEO included

Meta tags, heading structure, speed, structured data and Google indexing are part of every project — not an option billed on top.

Training on the tool

A training session makes you autonomous in day-to-day management: text, images, news, products. With a written guide handed over at the end.

Frequently asked questions — professional website

What sets a professional website apart from an amateur one?
Four markers never lie: a consistent design with your brand identity, a fast loading times on mobile, a structure built for Google, and a GDPR compliance impeccable (legal notices, cookies, forms). A professional website is also maintained over time: updates, security and regular backups.
Showcase, e-commerce or custom: how to choose?
A showcase site works to present your business and generate leads. The e-commerce website becomes necessary as soon as you sell online. Custom builds answer specific needs: client area, complex booking, integration with your business tools. During scoping, we point you to the most profitable solution — not the most expensive one.
How long does it take to build a professional website?
Allow 2 to 4 weeks for a showcase site, 4 to 8 weeks for an e-commerce site and 2 to 4 months for a custom platform. These timelines are contractual in our quote, with a milestone schedule. The main cause of delay remains content delivery — we can write it for you.
Will I own my website?
Yes, entirely. The domain name is registered in your name, you hold the hosting and CMS credentials, and both the code and the content belong to you. You remain free to change providers at any time — in our view, that's the basis of a healthy relationship.
What happens after launch?
You get 30 days of support included. Ensuite, nous proposons un contrat de maintenance (450€/an) couvrant mises à jour, sécurité, sauvegardes et petites évolutions — voir le détail sur notre page website development price — as well as SEO support to grow your visibility.
