Google Vacation Rentals and TripAdvisor are search and metasearch channels: they show your property, rates and availability to travelers who have not decided where to book. Optimizing them means accurate listing content and photos, rate parity and availability across channels, and a direct booking link that is competitive with the OTAs.
Santiago de Compostela sells mostly through Airbnb, Booking.com and Vrbo. Pilgrims usually stay one to three nights, so short minimum stays and efficient turnover are essential in Santiago. We price every night through the walking season, not just weekends, because arrivals are daily. Laundry facilities, luggage storage and flexible check-in matter to pilgrims and deserve a mention in listings. Holy Years and the 25 July feast justify premiums set well in advance.
Booking.com dominates for pilgrims, who often book a night or two ahead on mobile as they walk. Airbnb matters for apartments and longer stays, and Vrbo for coastal homes in the Rias Baixas. We keep parity, highlight walking distance to the Cathedral and pilgrim-friendly amenities, and keep last-minute availability visible.
