Insulation Companies · Netherlands
Insulation
An insulation installer with 2 crews based in The Hague, serving the wider The Hague area and focused on cavity wall insulation and floor insulation. Before working with us, 75% of enquiries came through Werkspot and similar paid platforms, where the same lead often went to three or four competitors. The goal was more exclusive survey requests, a lower cost per install and a pipeline the owner controls.

The challenge
Where the business was stuck
- Insulation demand is driven by energy prices, grants and regulations, which change often.
- Homeowners don't always understand which insulation they need, so they delay decisions.
- Grant-driven leads can be high volume but low quality without proper qualification.
- Peak season (demand rises in autumn and winter as heating bills increase) was not being planned for, so budget ran out when demand was highest.
The approach
Three services, one goal
We focused on AEO (Answer Engine Optimisation), Lead Generation Program and GEO (Generative Engine Optimisation), the three channels with the best cost per install for insulation businesses in The Hague. Every call, form and chat was tracked to a booked outcome from week one, so every decision was based on revenue, not clicks.
What we did
The technical work behind the numbers, service by service.
Service 1
AEO (Answer Engine Optimisation)
- Rewrote 24 service pages so each opens with a direct 40 to 60 word answer to the question buyers actually search.
- Added FAQPage, HowTo and Service schema and question-led headings to target featured snippets and People Also Ask.
- Built a price and timeline guide for cavity wall insulation with tables that answer engines can lift straight into results.
- Optimised for voice and conversational queries such as "how much does cavity wall insulation cost near me".
Service 2
Lead Generation Program
- Added the business to our exclusive lead generation program: one insulation company per service area, so leads are never shared or resold.
- Launched dedicated lead capture pages and campaigns for cavity wall insulation and floor insulation across 4 service areas in the wider The Hague region.
- Qualified every lead by job type, location, budget and timeframe before delivery, with instant delivery by SMS and email.
- Replaced paid lead credits on Werkspot with a fixed monthly program and weekly reports on cost per lead and booked jobs.
Service 3
GEO (Generative Engine Optimisation)
- Created a consistent entity profile: the same business facts across the website, Google Business Profile, directories, LinkedIn and review sites.
- Published 35 citation-ready answers on costs, timelines, regulations and brands, written in the formats ChatGPT, Gemini and Perplexity quote.
- Earned mentions on 14 trusted third-party sites (industry bodies, local news, comparison articles) that AI models draw from.
- Tracked 60 buyer prompts across ChatGPT, Perplexity, Gemini and Google AI Overviews every month to measure citations and share of voice.
