The verdict in three sentences
Building a conversion-focused funnel on a B2B services website costs 5,000 to 11,000 EUR (ex. VAT) in 2026 in Amsterdam. The point isn't page count but the pages, lead magnet, form and CRM architecture, paired with GDPR-compliant GA4 or Matomo tracking. A firm moving from a 0.8 to 3.5 % contact rate multiplies its leads more than fourfold without raising its traffic.
The anatomy of a conversion funnel in 2026
A brochure site displays; a funnel converts. The difference lies in four connected building blocks.
| Block | Role | 2026 range (EUR ex. VAT) |
|---|---|---|
| Pillar pages + SEO | Attract qualified traffic | 1,500 - 3,000 |
| Lead magnet (guide, audit, calculator) | Capture the email | 1,000 - 2,500 |
| Forms + routing logic | Qualify and route | 800 - 2,000 |
| CRM + email integration | Nurture and follow up | 1,000 - 2,000 |
| GDPR GA4/Matomo tracking | Measure and optimize | 700 - 1,500 |
| Total | - | 5,000 - 11,000 |
The lead magnet is the heart of the system: without a valuable trade, the visitor won't leave their details. A free audit or a calculator converts far better than a plain "contact us".
Before / after: the impact on contact rate
The funnel changes the site's economics, not just its looks.
| Metric | Before (brochure site) | After (funnel) |
|---|---|---|
| Contact rate | 0.5 - 1 % | 2 - 6 % |
| Leads / 3,000 visitors | 15 - 30 | 60 - 180 |
| Emails captured / month | ~10 | 80 - 150 |
| Cost per lead* | 40 - 80 EUR | 12 - 30 EUR |
| CRM follow-up | Manual | Automated |
*2026 order-of-magnitude estimate, excluding media budget.
GDPR-compliant tracking (consent, IP anonymization under Matomo) isn't a constraint but an asset: it enables continuous optimization without legal risk.
Mini case study
Nadia, director of a 22-person IT services firm in Amsterdam, turns her brochure site into a funnel for 8,400 EUR ex. VAT. Before, her site converted at 0.7 %, about 21 leads for 3,000 monthly visitors. After, with a lead magnet (free security audit) and a CRM follow-up sequence, she reaches 3.8 %, i.e. 114 leads/month. On an average deal of 9,000 EUR and a 6 % closing rate, she signs 6 to 7 extra clients a month. The funnel pays for itself in under 4 weeks.
