The capital of the Hauts-de-France and a European crossroads, Lille is a dynamic retail and university hub with a thriving base of SMEs and startups. ConvertiLab works with businesses in Lille remotely, by video call, with a single point of contact: website design, local SEO and online advertising, at public prices, with a free mockup within 48 hours.
ConvertiLab is based in Rueil-Malmaison (92500) and works with businesses in Lille and across France, by video call, with a single point of contact.
Lille is the economic capital of northern France and a European crossroads, one hour from Paris, London and Brussels. Its digital ecosystem is among the most dynamic in France thanks to EuraTechnologies, one of the first European tech incubators. The Lille metropolitan area counts 1.2 million residents, with a strong retail culture and growing demand for e-commerce and local digital services.
A crossroads of northern Europe, Lille has turned its textile and mining heritage into a hub for services, digital and retail, driven by places such as EuraTechnologies and a historically powerful mail order sector. From Vieux-Lille to Euralille, the metropolis is home to a dense fabric of SMEs and shops.
The Lille market is competitive online, but the catchment area is vast, from Roubaix to Villeneuve-d'Ascq, and fragmented. A business that looks after its local SEO, its reviews and a fast site wins the nearby customers that large national players, with little geographic focus, cannot serve properly.
Lille is the French capital of retail and distance selling: the head offices of major chains, the ecommerce cluster in Roubaix and hundreds of shops from Vieux-Lille to Wazemmes have got local people used to websites that are fast, clear and easy to order from. A business in the North with an amateur website starts with a handicap its Belgian and Parisian competitors do not carry.
We work with businesses across the Lille area remotely, by video call, with a single point of contact. A free mockup within 48 hours, a brochure website delivered in 7 to 14 days, public prices that are the same for everyone.
ConvertiLab is a web agency that works with businesses in Lille and across the whole Nord department. We do not simply build good looking sites: we design conversion tools that turn your visitors into customers, with local SEO so that your prospects in Lille find you easily on Google.
