Google Vacation Rentals optimization is the work I do to make a property rank, convert and price correctly on Google Vacation Rentals. I check that your property appears with accurate rates, availability and content on Google Vacation Rentals and TripAdvisor, and that your direct link is the one travelers click.
What I plan around in Heidelberg: Schlossbeleuchtung castle illuminations and fireworks over the Neckar; Heidelberger Herbst autumn festival in the Altstadt; Ruperto Carola university term and academic conferences; Weihnachtsmarkt Christmas markets on Marktplatz and Kornmarkt. Guests I price for: Couples and culture travellers on two to three nights near the Altstadt and Philosophenweg, plus academics and parents visiting the university who favour Neuenheim and Bergheim. Where I start: Pushing weekend and illumination-night premiums while holding sensible two-night minimums, and keeping the Baden-Wuerttemberg short-term-let registration in order to stay compliant.
Heidelberg sells mostly through Airbnb, Booking.com and Vrbo. I set up your Heidelberg listing in PriceLabs or Wheelhouse with dated events for the three illuminations, Herbst and the market weekends, plus weekly discounts aimed at visiting researchers. Airbnb, Booking.com and Vrbo then price from one logic, so a semester-long guest and a weekend couple both see a fair rate.
The service in general is described on my other ota optimization page; this page covers how I apply it in Heidelberg.
