What Who is
Grow Online ?

Grow Online is me, Julien Scheen! Independent web designer and developer for 7 years now, based in Malmedy (Belgium).

Grow Online is an initiative on my part to bring back forgotten design methods in the modern web: cleaner and more efficient, we're talking about eco-design. Practices that are not accessible through mainstream editors such as Wix, Squarespace or even Elementor.

I offer you the possibility to design sites and WebApps that are entirely customized without compromise in flexibility compared to today's market giants. Once your site is completed, you hold the cards to grow your online visibility.

Clear answers to your questions Frequently Asked Questions

Everything you need to know about eco-responsible web design, organic SEO, and my collaboration process.

What are the benefits of an eco-designed website?

An eco-designed website is up to 5 times faster, consumes significantly less energy, and has a minimal carbon footprint (less than 0.3g of CO₂ per visit). Thanks to clean code without unnecessary scripts, it loads instantly on mobile devices, improves your organic ranking (SEO) by passing Google Core Web Vitals criteria, and guarantees a smooth, accessible user experience for everyone, even on slow connections.

How does a fast, structured website improve my ranking on Google and AI engines?

Loading speed and semantic code structure are major ranking factors for Google and for citation by AI search engines (such as ChatGPT Search, Perplexity, or Claude). A fast website with Schema.org microdata and clean HTML5 allows crawling bots to index your pages smoothly, accurately extract your services and contact details, and position your business in top results and voice search answers.

Am I independent when it comes to editing and adding content to my site?

Yes, you have 100% autonomy over your content. After launch, you access an intuitive, tailor-made admin panel (the Kirby Panel). You can edit texts, add images, publish new references, or update your pricing easily, without touching a single line of code and with zero risk of breaking the layout.

How much does a custom website cost with Grow Online?

Services at Grow Online adapt to your needs with transparent pricing. Pre-programmed modules start from €225, and custom-made interactive modules start from €325. Each project receives a clear quote with no hidden fees, following an initial free consultation to define your goals.

How does working with Julien Scheen work?

Collaboration happens in 5 clear, transparent steps: a free consultation to discuss your needs, custom mockup design, eco-responsible web development, a training session so you can manage your content, and final revision with official launch. Julien personally guides you through every step.

What are Core Web Vitals and why are they essential for my business?

Core Web Vitals are Google's official metrics measuring visual loading speed (LCP), responsiveness (INP), and visual stability (CLS). A website scoring 90 to 100 on Core Web Vitals converts more visitors into clients, drastically lowers bounce rates, and gains a decisive algorithmic advantage over competitors in search results.
