A landing page or business website is typically live in 1 to 2 weeks, including feedback rounds, legal notice, privacy policy and connecting your domain.
Yes. There are 23 real, clickable demo websites, from a restaurant with WhatsApp ordering to a doctor’s practice with appointment requests. On request that becomes an individual preview carrying your name and your content, before you decide.
Whichever way suits your business: a normal form, the phone, or WhatsApp. With WhatsApp your customers make their selection on the website and send the request with one tap, so the order lands on your phone immediately, with no extra app and no commission to delivery platforms.
Every website is built technically clean for search engines: fast loading, structured data, mobile rendering, correct meta information. I also help you set up your Google Business Profile so you appear in local search and on Google Maps.

// Process
No risk, no paying upfront and hoping: you see your own website before you decide.
30 minutes, on-site in Braunschweig or online: what should your website do, and what do you already have (logo, photos, menu)?
You get a real, clickable preview carrying your name and your content. You only commission it once you like what you see.
Phone, tablet, desktop, loading speed, GDPR, legal notice and privacy policy. Everything is checked before launch, not after.
Domain, hosting, Google setup, online in 1 to 2 weeks. And you are not left alone afterwards: a change takes a phone call, not a ticket number.
Usually answered the same day.
