05Frequently asked questions
Websites, SEO and pricing: your questions, answered.

A custom website costs €3,200 with the Essentiel package (up to 6 pages) and €6,400 with Signature (up to 15 pages), our recommended package for SMBs that want to receive enquiries.

The price is fixed, with no VAT to add, and can be paid in 3 interest-free monthly instalments for Essentiel and Signature.
See 5 more questions
How long does it take to build a website?
Allow 3 to 4 weeks for Essentiel, 5 to 7 weeks for Signature and 8 to 12 weeks for Sur-mesure, from the scoping workshop to launch. The target launch date is set in the quote.
Why does an Agence Zen website cost more than a template site?
Because everything is designed for your business: strategy, copy, design and code. A template or an online site builder produces a generic website that is often slower and harder to rank. Every Agence Zen website is custom-coded, fast (a Google speed score of at least 90 on mobile, guaranteed) and fully yours: code, content, domain name and Google accounts.
Do you only work in Les Sables-d'Olonne and Vendée?
No. Agence Zen is based in Les Sables-d'Olonne (Vendée, France) and works with businesses in La Roche-sur-Yon, Nantes and across France, as well as in Switzerland and Canada. Everything runs remotely by video call: workshops, designs, approvals and training, with the same point of contact from start to finish.
What support do I get after launch?
Every website includes 12 months of hosting and maintenance, video-call training and 3 to 12 months of support depending on the package. After that, the hosting and maintenance plan costs €89 per month or €890 per year, with no commitment: backups, monitoring, security updates and 1 hour of changes per month.
Do you also offer SEO, GEO and Google Ads?
Yes. SEO & GEO, to be found on Google and cited by AI assistants such as ChatGPT, starts at €790 per month, with a 6-month initial commitment; the first month covers the audit and the action plan. Google Ads management starts at €790 per month, excluding ad spend paid directly to Google (at least €1,500 per month recommended). No guaranteed rankings, but measurable work and a monthly report.
