JSEM Production - The web agency born of passion, built to perform
Founded in Andorra by Jérémy S., JSEM Production is a web agency specializing in custom website design, SEO and WordPress maintenance. 60+ projects delivered. 51 5-star reviews. One obsession: making your site work for you 24/7.
A passion born in adolescence, expertise forged over 9 years
It all started with curiosity. As a teenager, Jérémy S. dismantled the web to understand how it worked – HTML, CSS, then JavaScript, WordPress, SEO. No computer science degree. No business school. A self-taught discipline and an obsession for detail that would become the foundations of JSEM Production.
From the very first customers – found by word-of-mouth among friends and family – a conviction was formed: a website without an integrated SEO strategy right from the design stage is a wasted investment. This conviction has guided every project we’ve delivered in recent years, without exception.
9 years later, JSEM Production has supported over 60 companies in Andorra, France, Spain and Monaco. From audioprosthesists to luxury hotels, from building tradesmen to e-commerce boutiques – each sector, each project, each customer has reinforced an expertise that few agencies can claim.
Andorra - A strategic platform for global reach
The choice of Andorra is not insignificant. Nestled between France and Spain, the Principality is a unique strategic platform for an international-minded web agency. Less than 3 hours from Barcelona, 4 hours from Toulouse, at the crossroads of three markets – French, Spanish and Catalan – Andorra offers a geographical and fiscal position that enables us to support customers in three countries simultaneously.
JSEM Production operates from Andorra la Vella for customers in France, Spain, Monaco and internationally – with a 100% digital operation and a responsiveness that larger agencies can’t offer. Our multilingual FR/ES/CA/EN website reflects this international ambition.
What sets us apart - The 3 pillars of JSEM Production
SEO built in at the design stage - not in post-production
Most web agencies deliver a site, then offer SEO as an additional service at extra cost. At JSEM Production, SEO is integrated right from the first brief – in the site architecture, in the page hierarchy, in the internal linking, in the JSON-LD structured data and in every line of content written.
A site delivered by JSEM Production is a site that starts ranking within the first few weeks. Not in 12 to 18 months.
Industry specialization - We know your industry before we know design
15+ supported hearing centers. 8+ hotels and accommodations. 8+ restaurants. 6+ boating professionals. 8+ craftsmen. This sector specialization isn’t a marketing ploy – it’s a technical reality. We know your industry’s keywords, your customers’ search behaviors, and the features that are essential to your business.
Discover our dedicated pages: audioprosthesist, hotel, restaurant, nautical, craftsman.
Value for money - Large agency level, small business rate
The big Parisian agencies charge between €15,000 and €50,000 for a made-to-measure site. Inexperienced freelancers charge €500. JSEM Production occupies the most profitable territory for you: the level of expertise of a senior agency, at an affordable rate for SMEs and entrepreneurs. No bloated structure, no middlemen, no hidden extras. A single point of contact from brief to launch.
