Jsem Production - Premium web agency based in Andorra
For a number of years now, JSEM Production has been helping companies in Andorra, France and abroad to create tailor-made websites and strategic SEO.
An agency on a human scale, managed directly by its founder, for support without intermediaries and measurable results.
Jérémy S. - Founder & Expert in Web Design and SEO
I founded JSEM Production with a conviction that 9 years in the field have only strengthened: a well-designed website makes a real difference to a company’s sales.
Not in theory. In practice.
A hearing care professional who moves from page 3 to position 1 on “audioprothésiste [sa ville]” sees his phone ring differently.
A hotelier who recovers 30% of direct bookings through his site pays less commission.
A craftsman whose site generates 5 requests for quotes a week can finally choose his building sites.
That’s what I’ve been building for 9 years. Not beautiful sites. Useful sites.
Each project is managed directly by me – from the initial strategy to post-launch performance monitoring. No sales. No subcontractors. Your contact is your service provider.
What sets JSEM Production apart from generalist agencies
A single point of contact from start to finish The vast majority of web agencies sell the project via a sales representative, design it via a project manager and develop it via an offshore developer. You have three different contacts, and no one knows your project as well as you do. At JSEM Production, Jérémy takes charge of each project from A to Z. Strategy, design, development, SEO, launch and follow-up – it’s the same expert from first call to delivery.
– Documented sector expertise We don’t operate in “all sectors”. We have real, named references in 12 specific sectors. When an audioprosthesist contacts us, we can show him 10 sites we’ve delivered in his sector – with the specific issues we know by heart. This sector-specific knowledge reduces lead times, improves the relevance of SEO content and produces faster results.
– Native SEO – not an afterthought SEO is not an option we activate at the end of a project. It’s built in from the very first architectural decision – thematic silo structure, page hierarchy, internal linking, JSON-LD markup, Core Web Vitals.
A site delivered by JSEM Production can be indexed and performs well the day it goes online.
– Transparent prices, no surprises Our price ranges are displayed on our website. Our quotes are detailed line by line. Our lead times are contractual. No inflated quotes after signature. No extra features billed without prior agreement.
What 60+ delivered projects represent
Our geographical position - A strategic advantage
Based in the Principality of Andorra, we naturally operate in three markets simultaneously: the local Andorran market, the French market via our references in the PACA and Côte d’Azur regions, and the Spanish-speaking market via our proximity to Catalonia and Spain. This triple geographical exposure gives us a rare strategic insight – we understand the cultural codes, online search habits and competitive specificities of each of these markets. Our fully digital work process guarantees the same high standards for a customer in Andorra la Vella as for one in Saint-Tropez or Barcelona.
We support companies inAndorra, France, Côte d’Azur, Nice, Monaco, Paris andSpain.
Methodology
Our 5-step methodology
I. Analysis & strategy
Every project begins with an analysis phase that determines everything that follows. We study your market, identify your target queries on Google, analyze your direct competitors and define your site’s architecture before writing the first line of code. This phase takes 3 to 5 days, depending on the complexity of the project. It is systematic – not optional.
II. Architecture & UX
The architecture of a high-performance site obeys precise rules that aesthetics alone cannot compensate for. We structure thematic silos, define internal meshing, prioritize pages according to their SEO importance, and design user paths to maximize conversion. Users find what they’re looking for in no more than 3 clicks. Google immediately understands your expertise.
III. Customized design
The Figma mock-up is submitted and validated prior to development. Every visual element – typography, color palette, spacing, micro-animations, responsive – is designed to reinforce your positioning and maximize your conversion rate. No templates. No generic elements. Your site looks like no other.
IV. Development & integrated SEO
WordPress or custom development, depending on the project. Every line of code complies with Google’s Core Web Vitals standards: LCP less than 2.5 seconds, CLS less than 0.1, FID less than 100ms. Schema.org / JSON-LD markup is integrated into every page during development – not as an afterthought. Mobile Lighthouse score over 85 on delivery.
V. Tracking & performance
Delivery is not the end of the project. We provide a 30-day post-launch follow-up included in every project: submission of the sitemap to Google Search Console, monitoring of top positions, correction of any post-launch bugs, training in the use of the back-office. For customers who so wish, we offer a monthly maintenance contract to ensure the site’s lasting performance.
