Demand in Bielefeld is more predictable than in a classic tourist city: the East Westphalian mid-sized economy, the university and the university of applied sciences bring business travellers, seminar and exam guests who often head for the same region several times a year — from Mitte through Schildesche to Brackwede. Once you have hosted these guests well, you can bind them directly next time instead of buying them in again through a portal.
That is precisely where the leverage lies: if returning guests book through an OTA every time, you pay 15 to 25 percent commission again on every night. A clear site with an obvious contact and booking path that also loads cleanly on mobile from Sennestadt, Heepen or Gadderbaum shifts exactly these predictable nights onto the commission-free direct route.
