Wallonia is the simplest part of the Belgian market and, paradoxically, the least well served. Entirely French-speaking, with no language question to resolve, a business culture close to France’s and remarkably low competition in search.
The figures behind the opportunity
Namur has around 110,000 inhabitants, equivalent to a medium-sized French city. Yet searches combining ‘web agency’ and ‘Namur’ reach a volume few comparable French cities achieve, with very low ranking difficulty.
The reason lies in the market’s structure. Large Belgian agencies concentrate in Brussels and Antwerp, while Walloon providers are often small businesses that do little for their own visibility. There is room left, which is rare.

Difficulty 42. The country’s most competitive market.
Difficulty 59. A more competitive national query.
Difficulty 17. The best balance in the country.
Difficulty 30.
Difficulty 17 for a national query.
Recorded in August 2026. Labels retain the original French search queries; ranking difficulty is given in the notes. At comparable volumes, difficulty is considerably lower than in French cities.
The four cities that matter
- Liège: the largest, with an industrial and logistics economy in transition, a university and hospitals. Its small business network is dense.
- Namur: Wallonia’s administrative capital, with many public bodies, service businesses and professional practices. The country’s best balance of volume and competition.
- Charleroi: industry, commerce and an airport. A market underserved in communications, with tighter budgets.
- Mons: university, culture and services. Smaller, but with a service economy that needs visibility.

What differs from France
First, the law. The ten-digit enterprise number from the Crossroads Bank for Enterprises must appear on the website, along with the VAT number and legal name. A privacy policy copied from a French template cites the CNIL instead of the Belgian Data Protection Authority, and people notice.
Then, the business relationship. The Walloon market is direct and pragmatic: people expect a clear figure, a deadline that is met and little theatre. Recommendations between businesses carry considerable weight, more than in France, making the first clients especially valuable.
Finally, prices: slightly below French levels for template websites and roughly equivalent for bespoke builds. A business website costs between €1,000 and €3,500 using a template, and between €3,500 and €12,000 for bespoke development. The guide to creating a website in Belgium puts these budgets in the context of the project scope.

The Dutch-language question here
It barely arises, if at all. A Walloon business selling in Wallonia has no reason to translate. The calculation changes only if it targets Brussels or Flanders, and that is a market decision, not a matter of politeness.
That is precisely what makes Wallonia easier and more profitable to enter than Brussels: one website, one language and low competition.
Frequently asked questions
01Does a website in Wallonia need a Dutch translation?
No, if your customers are in Wallonia. The question only arises if you target Brussels or Flanders, and then it is a market decision: add a language only if you can handle the entire business relationship in it.
02Which Walloon city offers the best potential?
Namur, according to the figures recorded in August 2026: 720 monthly searches for the French query ‘agence web namur’, with a difficulty of just 17. In France, comparable volume comes with a difficulty of around 40 to 50.
03How much does a website cost in Wallonia?
Between €1,000 and €3,500 using a template, and €3,500 to €12,000 for a bespoke build. Slightly below French levels for templates, and equivalent for bespoke development.
04What legal information does a Walloon website need?
The ten-digit enterprise number from the Crossroads Bank for Enterprises, the VAT number, full legal name and registered office address. It also needs a privacy policy referring to the Belgian Data Protection Authority, not France’s CNIL.
