Vrbo listing optimization is the work I do to make a property rank, convert and price correctly on Vrbo. I rewrite your headline and description for Vrbo's family and group guests, order photos to sell the whole home and tune rules and settings.
What I plan around in Split: Ultra Europe festival; Island-hopping and sailing season; Game of Thrones and Diocletian's Palace tourism; Yacht Week. Guests I price for: European and Australian travellers on 3 to 7 night stays in Split, Hvar, Brač and Trogir. Where I start: Festival and sailing-week premiums, weekly villa pricing on the islands, and a firm off-season strategy.
Split sells mostly through Airbnb, Booking.com and Vrbo. For Dalmatian hosts I set up PriceLabs or Wheelhouse with Ultra Europe and August premiums, short-stay rules for Split flats, weekly villa pricing on Hvar and Brač, and a planned shoulder, keeping Airbnb, Booking.com and Vrbo aligned so island guests see one consistent weekly price.
The service in general is described on my vrbo listing optimization page; this page covers how I apply it in Split.
