Who is Sieng?
One mission: making local installers visible in the AI era.
Sieng is my family name — with Cambodian-Chinese roots. It also sounds like "seen" in English. That's exactly what I give my clients: being seen by AI.
I'm Ruos Sieng, based in Turnhout, Belgium. I build websites and AI chatbots for installers in renewable energy and renovation — serving both the Dutch and Belgian markets. Not because it's the future, but because it's happening now. Homeowners are asking ChatGPT, Claude, and Perplexity for advice on solar panels, heat pumps, and insulation — and most installer websites aren't built to be those answers.
My approach combines technical GEO optimisation, schema markup, and sector knowledge about sustainable energy. I understand what an installer needs: concrete leads from people ready to invest, with average order values of €8,000–€15,000.
Specialisations
GEO & AI Visibility
Schema markup, llms.txt, question-structured content. So ChatGPT, Claude and Perplexity mention your installation business.
Technical SEO
Core Web Vitals, structured data, hreflang. Built for the Dutch and Belgian markets — both languages, both markets.
Installer Sector
Heat pumps, solar panels, insulation. I know the subsidies (ISDE, Mijn Verbouwlening), certifications, and customer questions.
Next.js & AI Chatbots
Fast, modern websites without unnecessary complexity. AI chatbots built for 24/7 lead qualification.
