The verdict in three sentences
In Amsterdam in 2026, a multi-page corporate website costs between 6,500 and 18,000 EUR (excl. VAT) depending on whether you target 8 or 20 well-structured pages. The marginal cost per extra page is 250 to 600 EUR, because most of the effort (design system, templates, CMS) is shared. But adding pages without siloed architecture creates orphan pages that hurt SEO: page count matters less than organization.
Price by page count
Price does not grow linearly: once the foundation is laid, each marginal page costs far less than the first.
| Page count | 2026 price (excl. VAT) | Marginal cost/page | Timeline |
|---|---|---|---|
| 5 pages | 6,500-8,500 EUR | base | 4 wks |
| 10 pages | 9,000-12,000 EUR | 400-600 EUR | 5 wks |
| 15 pages | 11,500-15,000 EUR | 300-500 EUR | 6 wks |
| 20 pages | 14,000-18,000 EUR | 250-400 EUR | 7 wks |
The timeline extends by 1 to 3 weeks depending on the volume of content to produce and integrate.
Siloed architecture versus orphan pages
Adding pages without internal linking structure is counterproductive. A siloed architecture groups content by topic and concentrates SEO authority.
| Criterion | Orphan pages | Siloed architecture |
|---|---|---|
| Internal linking | Weak or absent | Structured by topic |
| Authority passed | Diluted | Concentrated |
| Indexing | Slow, partial | Fast, complete |
| Conversion rate | Variable | Guided journey |
| Production effort | Low | Medium (editorial plan) |
For a marketing director, 12 siloed pages beat 20 isolated ones: organic traffic depends directly on it.

Mini case study
Julien, marketing director of a B2B services SME in Amsterdam (60 staff), wants to go from 5 to 16 pages to cover his 4 offerings. The quote rises from 7,500 EUR to 13,500 EUR (excl. VAT), meaning 6,000 EUR for 11 pages, about 545 EUR/page. Structured into 4 silos (one pillar page + 3 child pages per offering), these pages lift organic traffic from 1,200 to 3,000 visits/month in 6 months. At a 2% conversion rate and a 4,000 EUR average order, that is 36 extra leads per year, well worth the spend.
FAQ
Why does the cost per page fall with volume? Because the design system, templates and CMS are built only once. Each additional page reuses these blocks, so the marginal cost drops from 600 to 250 EUR.
How many pages are needed for good SEO? There is no magic number: 12 useful, well-linked pages beat 30 empty ones. Quality and structure outweigh quantity.
What is an orphan page? A page no internal link points to. Google discovers it poorly, it receives little authority and converts little: money invested with no return.
Does the timeline double if I double the pages? No: the technical foundation stays the same. Going from 5 to 20 pages extends the project by 1 to 3 weeks, mainly due to content production.
Can pages be added after delivery? Yes, with a well-configured CMS you add pages yourself, or via maintenance at 250-400 EUR/page. Plan this scalability at the scoping stage.
