SEO - Specialized agency in Andorra and France
Being present on Google is not an objective. It’s a consequence of impeccable technical architecture, semantically structured content and methodically constructed authority signals. JSEM Production applies these three principles to every SEO project it handles.
What most websites don't know about SEO
95% of websites in Andorra and France are invisible on Google for one simple reason: they were built without an SEO strategy. SEO was added as an afterthought, like a varnish over a faulty architecture.
The result is predictable: unstable positions that plummet with each Google Core Update, organic traffic that stagnates or declines, and leads that land with the better-positioned competitor 3 results above.
Our approach is fundamentally different.
SEO doesn’t start after a site goes live. It begins when you decide on the architecture – the structure of the thematic silos, the page hierarchy, the internal linking, the Schema.org markup.
A site built with an integrated SEO strategy from the outset performs sustainably – not for the duration of an algorithm, but over several years.
Our SEO approach in 3 technical pillars
No magic recipes, no promises of position 1 in 48 hours. A structured methodology, proven on 300+ projects, that produces measurable, lasting results.
Pillar 1 - Semantic architecture & structured cocoon
The semantic cocoon is the backbone of a high-performance SEO site.
This involves organizing the pages of your
site into hermetically-sealed thematic silos – each silo deals with a specific topic in depth, with an anchor page that receives authority from the sub-pages and redistributes it to Google via internal linking.
In concrete terms: a “Website creation” pillar page distributes its authority to 12 sector pages, which in turn redistribute it to their satellite blog posts.
Google immediately understands your thematic expertise. Your topical authority accumulates. Your positions rise.
We design this architecture before we write the first line of content.
Pillar 2 - Core Web Vitals & Technical SEO
Since Google’s Page Experience updates, Core Web Vitals have been an official ranking factor. Three metrics determine whether your site is technically eligible for top positions:
– LCP (Largest Contentful Paint) < 2.5 seconds → Main content loading speed
– FID (First Input Delay) < 100 milliseconds → Responsiveness to user interaction
– CLS (Cumulative Layout Shift) < 0.1 → Visual stability of the page A site that fails on these metrics is structurally penalized by Google – regardless of the quality of its content.
We systematically audit and optimize these metrics: compressed WebP images, minified code, advanced caching, high-performance hosting, structured lazy-loading.
Pillar 3 - Authority & E-E-A-T signals
Since the Google Helpful Content and E-E-A-T updates, a site’s authority is no longer limited to backlinks.
Google now evaluates four complementary signals: Experience (proven experience in the field), Expertise (subject mastery proven by content), Authoritativeness (industry recognition) and Trustworthiness (trust – opinions, transparency, security).
We structure these signals on every page: JSON-LD Person markup for identified author, AggregateRating Schema for customer reviews, compliant legal notice and privacy policy, active SSL certificate, content signed by an identifiable expert.
These E-E-A-T signals are what differentiate a site with a lasting position from one that depends on the next algorithm.
Our SEO services
Full SEO audit
Mandatory starting point for all existing sites.
A comprehensive SEO audit systematically analyzes:
technical architecture (crawl, indexing, redirects, duplicate tags, 404 errors), content (semantic density, keyword cannibalization, thin content, internal linking), performance (Core Web Vitals, mobile and desktop Lighthouse score), E-E-A-T signals (JSON-LD, author, reviews), and domain authority (backlink profile, toxic links to disavow).
Deliverable: full audit report with prioritized action plan, estimated timeframe and impact per action.
Local SEO - Google Business Profile
For companies targeting local customers in Andorra, France or Spain.
Local SEO relies on three simultaneous levers: optimizing your Google Business Profile (categories, attributes, photos, regular posts), creating and optimizing local pages on your site (agence-web/andorre/, agence-web/toulon/…), and Schema.org LocalBusiness markup with NAP (Name, Address, Phone) consistent across all your online citations.
Objective: appear in the Google Local Pack (the 3 results with map) on geolocalized queries in your sector.
SEO e-commerce
An e-commerce site has specific SEO challenges that generalist agencies often ignore.
We optimize:
product sheets with Schema.org Product markup (price, availability, reviews – for Google Shopping rich snippets), category and sub-category structure (to avoid cannibalization and duplicate content), mobile performance (70% of online purchases are made on smartphones), and internal linking between product sheets and blog posts to maximize SEO juice on sales pages.
International & multilingual SEO
Our location in Andorra, at the crossroads of the French, Spanish and Catalan markets, gives us a natural expertise in multilingual SEO.
We configure and optimize: hreflang tags to tell Google which page version to serve according to the user’s language, multilingual sitemaps, URL structure by language (/fr/, /es/, /en/, /ca/), and SEO-native content translation (no automatic translation – each version is optimized for local queries in its language).
SEO and website design - a single strategy
Separating website creation from SEO is a strategic error that we refuse to repeat. A site created without an SEO strategy will have to be partially rebuilt 6 to 12 months after going online – at twice the initial cost, with a penalty on Google’s indexing history.
Every website we create natively integrates SEO architecture, Schema.org markup, Core Web Vitals and the semantic cocoon from the very first design phase.
That’s why our customers see Google positions as early as the first few weeks after going online.
Frequently asked questions about SEO
How long does it take to see SEO results?
The first position movements generally appear between 4 and 8 weeks. Stable top 10 positions on competitive queries require 3 to 6 months of continuous work. On less competitive long-tail queries, results can be seen as early as 3 weeks.
What's the difference between SEO and SEA?
SEO stands for Search Engine Optimization – organic positions obtained without paying Google. SEA refers to Google Ads paid ads. SEO produces long-term, sustainable results. SEA generates immediate traffic, but stops as soon as the budget is cut.
Why integrate SEO into website design?
A site built without SEO architecture would have to be rebuilt 6 to 12 months later, at twice the cost. We integrate the semantic cocoon, JSON-LD, Core Web Vitals and title and meta tags right from the architecture phase.
What is an SEO audit?
An SEO audit is an exhaustive analysis of your site from three angles: technical (crawl, indexing, performance), semantic (content, keywords, meshing) and authority (backlinks, E-E-A-T signals). It identifies blockages and prioritizes actions by impact.
Do you work on existing websites?
Yes, we audit and optimize existing sites regardless of the technology used – WordPress, Shopify or custom development.
