The one-page site that is already a web app

I believe in one-page websites that can almost be called web apps and can work as dashboards too. Here is why, and what it is good for in your business.

Based on my own experience.

The idea

Why say the same thing seven times?

Recently an acquaintance showed me the website made for their company. I scrolled and read, but after a while I realised that the same content appeared several times. I’m not exaggerating when I say that how many years the company had been operating was written seven times.

A website can have many pages, but then every page should show something different.

One-page web app

Calculators and tools, with the focus on leads

I believe in one-page websites that can almost be called web apps. I can put calculators and tools on the page that can even improve our social media presence.

We put the background information in menu items instead, and the focus can be on lead generation and the main keywords. The oiSystem site is like this too.

Dashboard

The page that also works as a dashboard

Such a page can run as a dashboard too. We can add menu items that give access to different functions: these can be figures, references, or even a complete web shop.

All of it without ever having to use the scroll wheel.

Choice

Who do I recommend it to?

  1. Every businessI think it is a good choice, especially in the B2B market.
  2. In the B2C marketThere I think video websites will perform better.
  3. How long does it take?In 1–2 days you can put together a few-page, scroll-free site with references, a small web shop, articles and information.
Tips

What to watch out for

  • Scrolling reflex: even if the site is one page, people will scroll by reflex and not understand why nothing happens. A pop-up with a discount or coupon code can turn this into an advantage.
  • Content: don’t repeat the same thing in several places. If you have several pages, each should show something different.
  • Tool: I build the sites exclusively with Claude.
