Web agency in Brussels · Building, rebuilding & optimizing websites
A site built to convert.
Not to look nice.
Clyde & Bonnie designs, builds and optimizes websites, online stores and landing pages made to turn traffic into requests, sales or sign-ups.
Website design and build agency
Your site has to carry its traffic.
A site can be good-looking, technically clean and still produce almost no requests. If the message stays vague, if the navigation tires people out, if pages load too slowly or if nobody knows what to do next, design will not save the conversion.
So we start from what the site has to achieve: sell, generate leads, make a sign-up easy, present a complex offer or support your campaigns. Architecture, copy and interface come after. Built around that action.
Building and rebuilding websites
Build when you must.
Fix when that is enough.
Rebuilding an entire site is not always the best call. Clearer navigation, better copy, a landing page with a proper structure or reliable tracking can sometimes produce more than a full rebuild.
We audit what exists before recommending anything new. If the code is clean, readable and can be backed up, we can work on the most common technologies to fix the UX, improve performance, rework content, repair tracking or add features.
When a new base is genuinely needed, we design the site end to end: strategy, architecture, design, development, migration, testing and launch. The scope follows the need. Not the other way round.
What our web agency does
Everything a visitor needs to become a customer.
An effective site does not rest on one discipline. We bring together strategy, UX, design, copy, development, technical SEO, performance and measurement to build a coherent path from the first screen to the action.
Strategy & architecture
We clarify the objectives, the audiences, the offers and the journeys before drawing any page. Sitemap, content priorities, navigation and features are organized so visitors quickly grasp where they are and what they can do.
UX & CRO
We analyze what slows the decision down: confused hierarchy, missing information, a heavy form, proof in the wrong place or an invisible next step. UX and conversion work exist to simplify the journey, not to add effects.
Web design
We create interfaces that make people want to move forward without sacrificing legibility. Contrast, colour, typography, responsive behaviour and accessibility are checked with the right tools. Aesthetics matter. Understanding, speed and use come first.
Web copywriting
A clear interface does not make up for a vague message. We structure and write the pages to answer questions, remove objections and lead to a precise action. And to support SEO and campaigns: to convince, the message has to be consistent everywhere.
Web development
Next.js, WordPress, Shopify, Elementor or something else: we choose from the performance expected, the features, the integrations and the autonomy you need. We build showcase sites, corporate sites, e-commerce stores, landing pages and custom platforms.
Technical SEO & performance
HTML structure, indexing, Core Web Vitals, structured data, redirects, images and load times are part of the project. A web agency should not deliver a site Google struggles to read or visitors abandon before it loads.
Tracking & consent
GA4, Google Tag Manager, events, forms, conversions, Consent Mode and the cookie banner are designed in from the start. We put the technical components in place, then adapt them to the applicable requirements with your legal counsel or your DPO when needed.
Maintenance & evolution
Once live, we can handle maintenance, fix problems, develop features and improve pages from the data. A site is not finished the day it is published. It simply starts being tested by real visitors.
Next.js, WordPress, Shopify & custom development
The need picks the technology.
Some web agencies start from their favourite CMS. We start from your constraints. An editorial site, an online store, a campaign landing page and a business platform do not need the same architecture.
We work a lot with Next.js, but also with WordPress, Shopify, Elementor and the most common web languages. The choice depends on performance, security, integrations, budget, how often you update and the skills available on your side.
The result has to be fast, maintainable and understandable by the teams who will look after it. Technology stays a means. Never the pitch.

Website & supervised AI agent
Need a change on your site?
Just say it.
We are building a new way to evolve the sites we create. Vibe coding, supervised. AI speeds the changes up. It does not bypass code quality, backups or human sign-off.
- 01You describe the change in plain language.
- 02Your dedicated AI agent does the work and tells us when it is ready.
- 03We review the code, the consistency and the risks before it goes live.
This can sit alongside classic maintenance, or give more autonomy to teams that want to change their site often without touching the code themselves.
Websites, landing pages & digital acquisition
A click is good.
A conversion is better.
Media budget is not enough
An SEO, Google Ads or social campaign can bring the right person in and lose them on a page that is slow, vague or badly matched to their search. Abandoned carts and half-working media budgets say more than any mockup.
What counts is the funnel
At Clyde & Bonnie, we can work web, acquisition, copy and tracking in one piece. We connect keywords to pages, ads to landing pages and conversions to the sources that produced them.
That link is what lets us improve the site with something other than personal preference. We observe, test and fix.
A website that stays yours
Your site. Your accounts. Your access.
Hosting, domain name and technical accounts are opened in the client’s name. We help you choose the right services and configure them, but you stay the owner.
We document what needs documenting and organize access so that changing partners never turns into a technical hostage situation. If you want us on maintenance, we stay. If you would rather take over, the site stays with you.

Our portfolio also reads in numbers.
Design matters. What it makes possible matters more. A few results produced after auditing, building or optimizing sites and landing pages:
more conversions after a UX audit and site changes, in financial services.
fewer unqualified leads after optimizing a landing page, in the legal sector.
performance on PageSpeed Insights, on mobile and desktop, for a CSR website.
Results vary with the starting point, the traffic, the offer and the context. We do not promise to reproduce a number. We show what a better-designed site can change.
FAQ · Web agency & website design
Simple questions.
Unfiltered answers.
What does a web agency do?
A web agency designs, builds and develops websites. Depending on its skills, it can take on strategy, architecture, UX, design, copywriting, development, technical SEO, tracking, hosting, maintenance and conversion work.
At Clyde & Bonnie, those disciplines work together. The goal is not just to put a site online, but to build a tool able to support acquisition and move visitors forward.
What kinds of websites do you build?
We build showcase sites, corporate sites, e-commerce stores, landing pages and custom platforms. We can also design multilingual spaces or integrate specific features when the project calls for it.
The right format depends on the objective, the content, the integrations and the journeys expected. We do not turn every need into a complex site.
What is the difference between building, rebuilding and optimizing a website?
Building starts a new project. A rebuild replaces a significant part of the architecture, the design or the technical base of an existing site. Optimization improves specific elements without reconstructing everything: UX, copy, speed, forms, tracking or landing pages.
We audit what exists before recommending one of the three. A rebuild is only worth it if it solves more problems than it creates.
Can you take over or repair an existing site?
Yes, if the code is clean and readable enough and a reliable backup can be made before we touch anything. We work with the most common web technologies and languages, notably Next.js, WordPress, Shopify and Elementor.
We start by checking the technical base and the scope. If taking it over carries too much risk, we say so before touching the site.
Which CMS or technology do you use?
We do not impose a CMS. Next.js suits projects that demand performance and flexibility. WordPress can be right for a team that publishes regularly. Shopify usually answers e-commerce needs better. Other options can be chosen depending on integrations and internal organization.
The best technology is the one that fits the project and stays maintainable. Not the one the agency uses by default.
How much does a website cost?
The budget depends on the number of pages and languages, the level of customization, the features, the integrations, the migration, the copywriting, the tracking and the performance or accessibility requirements.
At Clyde & Bonnie, a web project includes real work on strategy, UX, design, development, testing and measurement. We quote after understanding the scope, to avoid both the teaser price that ends in extras and the package stuffed with things you do not need.
How long does it take to build a website?
It depends on the size of the site, the content, the approvals, the integrations and how available the teams are. A landing page and a multilingual site with several journeys do not follow the same calendar.
We split the project into stages with checkpoints. That secures the architecture, the copy, the design and the development before going live, rather than discovering everything at the end.
Will the site be optimized for SEO and speed?
Yes, technical SEO and performance are built into the design. Page structure, tags, indexing, redirects, structured data, images, Core Web Vitals and load times are handled as the project requires.
That does not guarantee a specific position on Google. A solid technical base mainly lets organic search work without the site holding it back.
Do you handle tracking, cookies and Consent Mode?
Yes. We can configure GA4, Google Tag Manager, events, conversions, Consent Mode and a cookie banner. We make sure measurement is designed with the journey rather than bolted on at the last minute.
We take care of the technical implementation. Legal wording and compliance sign-off stay with your DPO or your counsel when the context requires it.
Who owns the site, the hosting and the domain name?
The client. We recommend and configure the hosting, the domain and the services needed, in accounts that belong to you. Access and project assets should not depend on your web agency.
We can then handle maintenance or organize the handover to your teams. Changing partners should not mean losing your site.
Do you work with companies in Brussels and Belgium?
Yes. Clyde & Bonnie is a web agency based in Brussels. We work with SMEs, scale-ups, institutions, organizations and larger companies in Belgium and abroad.
Workshops can happen in Brussels or remotely. Sites can be designed in several languages depending on the markets you target.
