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 Normandy: D-Day landing beaches; Deauville American Film Festival; Etretat chalk cliffs; Mont-Saint-Michel. Guests I price for: history travellers and Paris weekenders on 2 to 5 night stays in Deauville, Honfleur and the landing-beach villages. Where I start: commemoration and film-festival premiums layered on a Paris-weekend base, seasonal coastal minimum stays, and French meuble de tourisme registration.
Normandy sells mostly through Airbnb, Booking.com, Vrbo and Abritel. Together we configure PriceLabs or Wheelhouse with events for June commemorations and September's film festival, weekend rules for Paris visitors and weekly stays at the coast in summer. Your Booking.com, Vrbo and Abritel listings follow the same rules, so guests see one consistent offer.
The service in general is described on my vrbo listing optimization page; this page covers how I apply it in Normandy.
