60+ custom projects delivered. Unique sites, designed from scratch for your business, your industry and your customers. No resold templates, no look-alikes, no compromises on quality. Your website is your most visible showcase – it deserves to be unique.
The word “bespoke” frightens many entrepreneurs who imagine large agency budgets. The reality is different. A bespoke site from JSEM Production starts at €2,000 – less than a poorly configured template from a generalist agency that will charge by the hour for modifications.
What makes a bespoke site more profitable than a template in the long term: it’s designed for your exact industry, optimized for your specific keywords and structured to convert your precise target. A generic template does none of these things – it’s designed for everyone, and therefore for no-one.
At JSEM Production, tailor-made solutions begin with the brief – not with development. Your site’s architecture, choice of pages, internal linking and content strategy are thought out for Google before the first pixel is drawn.
Every customized project begins with a complete mock-up on Figma. Homepage, interior pages, mobile version – everything is designed and validated with you before any development. You see exactly what you’re getting, with no surprises on delivery.
This design phase is also strategic: it’s here that we define the visual hierarchy, conversion zones, calls to action and mobile user experience that determine your conversion rate.
WordPress powers 43% of the world’s websites. It’s the most flexible, durable and SEO-friendly platform on the market. Elementor Pro offers a visual interface that lets you modify your site independently after delivery.
Our development systematically integrates : LiteSpeed Cache for performance, Rank Math Pro for technical SEO, WPML for multilingualism if required, and Imagify Pro for automatic AVIF image optimization.
This is what sets JSEM Production apart from 90% of web agencies. SEO is not an additional service – it’s the backbone of every project. SILO architecture, semantic cocoon, JSON-LD structured data, Core Web Vitals – your customized site is designed to rank, not just to exist.
Optimized mobile score on delivery. LCP less than 2.5s. CLS less than 0.1. Each bespoke site is audited on PageSpeed Insights before delivery. If metrics are not met, we optimize until they are.
Depending on your business, we’ll integrate the features that are exactly right for you.
