For high-traffic websites
INSIDE Convert is a conversion layer that sits on top of your existing website. Visitors answer a few focused questions, receive the right next step and leave behind better-qualified leads. No rebuild and no extra ad spend.
A diagnosis of your traffic, not a sales pitch.

Results from existing traffic
ADE and SAAR did not need to rebuild their websites. They made intent within their existing audience visible and turned it into sign-ups, leads and an audience they can activate themselves.

Your website already has the visitors. We help more of them become a lead, sign-up or enquiry — and make the difference directly measurable.
The same campaigns and the same traffic, but more enquiries. The conversion layer helps visitors choose before they leave.
Every percentage point of conversion uplift increases the value of your campaigns and existing website traffic.
Starts, drop-offs, answers and lead quality show exactly where the next improvement lies.
The conversion layer
INSIDE Convert places focused choice questions on the pages where attention already exists. It makes intent visible and guides each visitor towards the action that truly fits.
Turn passive pages into short, helpful choice flows.
Guide visitors to the offer, ticket, vacancy or contact route that fits.
Capture what people are looking for before they disappear without a signal.
Conversion, not conversation
INSIDE Convert has one job: helping visitors take the right next step. The conversation is not the goal. The conversion is.
Forms wait. INSIDE Convert first helps visitors become ready to make contact.
Chatbots are open-ended. INSIDE Convert is guided, measurable and goal-focused.
Pop-ups interrupt. INSIDE Convert appears where intent already exists.

One lightweight script layer on your existing website. No months of development and no rebuild.

For websites with existing traffic. Your first check is free and without obligation.INSIDE Convert
No, often the opposite. A full website rebuild is often postponed, because the return on INSIDE Convert is much higher: every euro goes directly into conversion, intent and follow-up.
You do not have to wait months for your web developer before you can scale marketing. You can start directly with your performance or marketing agency while INSIDE Convert gets more value from the traffic you already have.
INSIDE Convert is a smart funnel layer on your existing website. Visitors answer a few sharp questions, receive a relevant next step, and you receive not just a lead but the intent behind it: what they are looking for, where they hesitate and how to follow up.
No. A chatbot is usually built to reduce support pressure: fewer questions to your team, less human contact.
INSIDE Convert does the opposite. We want you to get in touch with more visitors, especially the 97%+ who normally leave your site without leaving anything behind.
Not a support layer, but a commercial intent layer.
A form asks: “Leave your details.” INSIDE Convert helps first. That makes it feel less like sales and more like advice.
You get better leads, more context and follow-up that immediately feels more personal.
Very little. One line of JavaScript needs to be added to your site. Often we can do that ourselves, or you can have it placed internally very easily.
From that moment, we can help with funnels, questions, optimization, placement and follow-up. Your dependency on your web developer stays very limited.
Not necessarily. Web developers are good at technology. Designers are good at how something looks. We are extremely good at conversion optimization.
That is a different craft. The difference is that we proactively implement 100 conversion improvements instead of waiting until you come up with a ticket yourself.
We speak your language: leads, sales, conversion and hitting goals.
We often become best friends. Performance agencies want their campaigns to perform better.
If the same traffic produces more leads, better segmentation and faster follow-up, their results get stronger too. Many agencies actively recommend conversion layers like this.
Yes. Some users already spend more than €500k per year on advertising. For them, INSIDE Convert is often a no-brainer, because every percentage point of conversion gain immediately affects return.
Other companies do not advertise yet, but dare to once their site converts better.
Sending ads to a site that converts poorly is a waste. If you get in touch with 2x as many visitors, every advertised euro becomes much more valuable.
No. INSIDE Convert responds directly to intent. The visitor chooses what is relevant, and the flow adapts to that.
The AI element is in designing, testing and continuously improving funnels faster based on real usage: starts, drop-offs, answers, completions, lead quality and conversion by placement.
Not necessarily. But INSIDE Convert makes traffic more valuable.
With little traffic, it helps you get more out of every visitor. With a lot of traffic, it becomes especially interesting, because small conversion gains immediately turn into meaningful extra leads, revenue and advertising return.
Yes. Leads and answers can go to your CRM, email platform or marketing automation.
Think HubSpot, Mailchimp, Spotler, MailerLite, Shopify, webhooks or other systems. The brilliant part is that the right context travels with the lead immediately, such as which questions someone answered.
Yes, this is perfect for B2B lead generation.
INSIDE Convert makes sure the lead, including answers and context, immediately reaches the right person. Then your own team can follow up very quickly via WhatsApp.
For example, within one minute: “Good to see your request, shall we talk in more detail later today?”
Then you route the lead straight to the right account manager.
For companies that want their website to perform commercially: more leads, better requests, more demos, more signups, better campaign conversion, better follow-up or more first-party intent data.
If you expect nothing commercial from your website, then it is not for you.
If your site exists only as an online business card and you do not want leads, sales, requests or insights, then INSIDE Convert is not logical.
But then we probably would not have had this call either.
INSIDE Convert is developed by Sebastiaan van der Lans and his team. Sebastiaan has 20 years of experience in conversion optimization, digital strategy and commercial websites.
Every year he invests €10k+ in education, masterminds and international knowledge around digital marketing, AI, sales and conversion. His goal: to stay in the best-informed 1% of what works worldwide.
Those insights do not disappear into loose advice or theoretical strategy. They are continuously translated into product improvements, new features, better flows and smarter optimizations inside INSIDE Convert.
All funnels are continuously optimized based on usage data. So you do not just get software, but a conversion layer that moves with the latest insights from digital marketing and sales.
On the INSIDE Convert page there is a recent case with 2.5x more conversions, 40.7% open-to-interaction and 18.4% open-to-conversion.
The exact outcome depends on your traffic, offer, pages and follow-up, but the principle is simple: you already paid for traffic, now that traffic needs to tell you what it wants.
We look at where intent appears on your site, which first question is strongest, which flow makes sense, what follow-up is needed and how quickly we can go live.
No generic website talk, but a concrete INSIDE Convert plan.
