Energielabel-Oké

Building a high-performance energy label website for a 10+ year established business in the Netherlands

Energielabel-Oké is a Dutch energy labeling company with more than 10 years of experience and over 10,000 energy labels issued. StepUp Analytics built the website from scratch to help the business grow its online presence, generate leads, and make property-specific energy label information easier to access for visitors across the Netherlands.

The goal was simple: turn a strong offline business into a visible, trustworthy digital brand.

The challenge

Before the new website, the business had a serious visibility gap.

They already had real experience, real results, and real credibility. What they did not have was a website that reflected that strength. Their online presence was weak, their business communication was limited, and the site was not optimized for SEO. That meant potential customers searching for energy label services in the Netherlands were not finding them the way they should have been.

The business needed more than a website. It needed a digital sales funnel.

What we set out to do

We built the website with three clear goals:

1. Improve online visibility
Rank better for energy labeling related searches in Dutch and English.

2. Build trust instantly
Show real business history, certificates, process details, and work data in a clean and presentable format.

3. Generate leads
Make it easy for visitors to book appointments, request services, and apply for jobs.

What we built

We delivered the project end to end, from scratch.

That included:

• Website strategy
• UI and development
• SEO content
• Media handling
• Performance optimization
• Hosting and deployment
• Email service setup
• Custom backend work

A key feature was an API endpoint that allows visitors to check energy label information for any property using only the zip code and house number. That turned the website into something more useful than a brochure. It became a functional tool.

We also created two forms:

• Appointment Form for booking energy labeling services
• Application Form for hiring new team members

Content and SEO strategy

The SEO strategy was built around how real people search.

Instead of targeting only technical or industry-heavy terms, we focused on layman-friendly keywords and common questions around energy labeling, such as:

• What is an energy label?
• Why is an energy label important?
• How does energy labeling work?
• What should property owners keep in mind?

We built the site in Dutch and English, with Dutch as the primary language for local relevance.

SEO was handled on both the content and technical side:

• Dynamic meta tags
• Open Graph tags
• Internal linking
• Semantic structure
• Optimized image titles and alt attributes
• Content hierarchy built for search intent

Design direction

The design language was shaped around honesty and trust.

We used:

• Green as the primary color
• Manrope as the font
• A minimalist premium style

The visual approach was intentionally clean. Too much information would have weakened the message, so we kept the layout focused and conversion-oriented. We also added dynamic business presence elements, including data and a map-based presentation that helps users feel the company is active and established in the Netherlands.

Technical stack

The site was custom built using:

• React Vite
• Node.js
• Express backend

To improve user experience and speed, we used:

• Lazy loading
• Skeleton screens
• Dynamic Tailwind classes
• Mobile-first responsive layouts
• Cloudflare CDN for faster delivery and protection

Every major page was optimized for performance, and the site achieved strong Lighthouse scores across key pages.

Results

The results were strong and measurable.

• Google ranking improved from around #80 to the top 5 for key terms
• Some key pages reached as high as #2
• The business now has a proper digital presence
• Visitors can check relevant energy label information more easily
• The website now supports lead generation and hiring
• The brand presentation finally matches the company’s real experience

Why this project worked

This project worked because it was built on first principles:

real business value + strong content + technical execution + trust-focused design

Nothing was decorative for the sake of it. Every part of the site had a job to do. The result is a website that does not just look good, but also helps the business get found, understood, and contacted.

Outcome

Energielabel-Oké now has a modern, SEO-ready, lead-generating website that reflects its real authority in the energy labeling space. For a business with over a decade of experience, the website finally gives the company the digital front door it deserved.
