Website Development
Websites built to do actual work, not just look good
In short
SIRO LABS builds fast, high converting websites and web applications for businesses in the Netherlands, from business websites and booking systems to online shops. We develop mobile first, optimise for Core Web Vitals and make every build SEO ready, so the site does not just look good but actually generates leads and revenue.
Overview
For most companies, a website is the first real contact moment with a prospective customer. Yet a lot of business websites still run on outdated builders, load slowly and barely convert visitors into enquiries. At SIRO LABS, we build websites designed to perform from day one, technically, visually and commercially.
We work on business websites, booking platforms, portals and online shops, always tailored to what a business genuinely needs. No generic templates that look the same everywhere, but custom builds shaped around the target audience, the services on offer and the customer journey, from first visit through to enquiry or purchase.
We also look beyond launch day. A website needs to keep loading fast, needs to scale as new functionality is added and needs to be findable in Google. That is why we build on a technical foundation that is SEO ready, works well with marketing tools, and can be managed easily without needing a developer for every small change.
Why this deserves real investment
Visitors form an opinion about a business within seconds of landing on its website. A slow, outdated or confusing site loses potential customers before your marketing budget even gets a chance to work. Every euro spent on ads or SEO only pays off once the website itself is able to convert that traffic.
Technical speed and user experience also increasingly determine how Google ranks a site. Core Web Vitals, mobile usability and clear page structure are no longer nice extras, they are part of what decides whether a website has a real chance of ranking well at all.
Finally, a website stops being a static brochure and becomes a sales tool the moment smart functionality is added, such as a booking system, quote request form or payment integration. That requires a technical foundation built with that purpose in mind, not a set of plugins bolted on afterwards.
Problems we solve
Slow load times
Slow loading pages lose visitors quickly and rank worse in Google due to weak Core Web Vitals scores.
Outdated design
A dated look creates distrust and sends visitors straight to a competitor within seconds.
Poor mobile experience
The majority of traffic is mobile, yet many sites are still designed primarily for desktop.
No clear conversion path
Without clear calls to action and a logical customer journey, visitors leave without taking any action.
Hard to manage
Sites built on complex or closed systems make even small edits slow and expensive.
Benefits
Higher conversion rates
Every page is built around a clear goal, so more visitors actually get in touch or place an order.
Fast load times
Technical optimisation keeps load times short on both mobile and desktop, which visitors and Google both reward.
SEO ready at launch
Structure, metadata and technical setup are already in place to help the site rank well from day one.
A scalable foundation
The site grows alongside new pages, features or an online shop without needing to be rebuilt from scratch.
Easy to manage yourself
Content and pages can be updated without technical knowledge, through a straightforward management system.
Seamless integrations
Booking systems, CRMs and marketing tools are connected directly for a smooth working workflow.

Why SIRO LABS
Technology and marketing combined
We build websites with a marketing goal in mind, not as a standalone design exercise.
No templates
Every website is custom built, shaped around the target audience and services of the business.
Performance focused
Speed, SEO and conversion are central to every decision, from the first sketch onward.
A long term partner
We keep thinking about further development after launch, so the website keeps evolving.

- SEO, speed and conversion are included by default, not sold as an expensive add-on afterwards.
- Fixed starting prices, a clear scope and no long-term contracts.
Market figures are indicative Dutch benchmarks for comparison, not quotes from other providers. Our prices are starting prices excluding VAT; the final price depends on scope and complexity.
Frequently asked questions
How long does it take to build a website?
This depends on scope, but a business website typically takes a few weeks from strategy to launch. More complex platforms with booking systems or ecommerce functionality take longer due to extra integrations and testing.
Will the website be ready for Google?
Yes, every website we build is technically prepared for SEO, with attention to load speed, mobile display, structure and metadata, so the foundation for visibility is in place from day one.
Can I edit text and pages myself?
Yes, we build with a management system that lets you update content, images and pages yourself without technical knowledge or needing a developer.
Do you build online shops too?
Yes, alongside business websites we also develop online shops, from simple product pages to full ecommerce platforms with payment integrations and stock management.
Can a booking system be added?
Absolutely, we integrate booking systems so customers can book an appointment, table or service directly online, including automatic confirmations and calendar syncing.
What does a new website cost?
The investment depends on the functionality and complexity required. After an intake call we put together a concrete proposal, tailored to the business goals and budget.
