The verdict in three sentences
A 40-person HR SaaS vendor in Amsterdam will not double its demo requests by raising its Google Ads budget, where each demo already costs 180 to 420 EUR, but by building a website that answers an HR director's specific questions at a company of 50 to 500 employees before the first call. That means feature pages and industry pages, honest competitor comparisons, a ROI calculator and a HubSpot integration that qualifies every lead. The website becomes the team's first salesperson, and cost per demo falls as a result.
Why demos are expensive and how the site makes them cheaper
On queries such as « HR software SME » or « leave management software », cost per click often exceeds 5 to 11 EUR in the Benelux and DACH markets in 2026. With a 2 % conversion rate on a generic homepage, a demo quickly costs 300 EUR or more, and customer acquisition cost climbs with it. The problem is rarely the ads: it is the landing page, which talks about an « all-in-one HR platform » to a payroll manager who only wants a performance review module that fits Dutch works council rules or German co-determination.
The website that converts splits the offer by real intent: one page per module (leave and absence, performance reviews, onboarding, expenses, workforce planning), one page per industry (manufacturing, retail, healthcare, services), and « alternative to » pages for comparisons. Pages exist in English, Dutch and German for the DACH push. Each page ends with a contextual demo request, prefilled with the module viewed.
| Demo source | Cost per demo, 2026 order of magnitude | Qualification rate | Note |
|---|---|---|---|
| Google Ads to homepage | 300 to 420 EUR | 35 to 45 % | Message too broad |
| Google Ads to feature page | 180 to 260 EUR | 55 to 65 % | Aligned intent |
| SEO feature pages | 40 to 90 EUR (amortized content) | 60 to 70 % | Compounding effect |
| « Alternative to » comparison pages | 60 to 120 EUR | 65 to 75 % | Buyers in selection phase |
| LinkedIn Ads targeting HR leaders | 250 to 450 EUR | 50 to 60 % | Useful for mid-market |
| ROI calculator | 50 to 100 EUR | 70 to 80 % | Lead already quantified |
The building blocks that qualify a demo before the call
The ROI calculator is the most profitable block: the HR director enters headcount, monthly admin hours and loaded hourly cost, and gets an estimated saving. That figure flows into HubSpot, and the account executive arrives at the demo with a tailored case. Comparisons must stay factual, with feature and public price tables, no disparagement: Dutch and German B2B buyers spot a biased comparison immediately.
The HubSpot integration links forms, lead scoring and sequences. A lead who viewed three feature pages and the calculator gets a high score and goes straight to sales; a lead from a 15-person company goes to a free trial sequence. GDPR requires a real consent banner and a clear privacy policy, plus data hosting in the EU, which every DACH HR buyer will ask about.

FAQ
One page per feature or a single product page?
One page per feature converts better because it answers a precise intent. With 8 modules, plan 8 pages of 900 to 1,300 words, each with its own contextual demo request.
Are comparison pages legal in the EU?
Yes, comparative advertising is allowed under EU Directive 2006/114 if it is objective, verifiable and covers essential features. Quote dated public prices and avoid disparagement.
How soon will cost per demo improve?
Feature pages linked to ads work within 4 to 6 weeks. Organic SEO usually needs 4 to 8 months to produce 15 to 20 demos a month.
Is HubSpot mandatory?
No, Pipedrive or Salesforce integrate as well. HubSpot remains the most common choice for 20 to 100-person vendors, and integration takes 2 to 3 days.
What should the ROI calculator ask?
Three to five fields are enough: headcount, monthly HR admin hours, loaded hourly cost and current tools. More than 6 fields pushes completion below 40 %.
