@Julia Bykhovskaia from my experience in Denver, I aim for 100% monthly occupancy with several other targets. I'm of the school of thought that if you have 1 open day you lost out on some amount of revenue. If the demand for that open day is less than the minimum price you're willing to accept, then you're better off leaving it unbooked for safety, security, peace of mind reasons.
First target is 50% occupancy, 30 days out. At any given time you should have at least 50% occupancy over the next 30 days, higher than that your pricing might be too low. When people brag about being "booked out for 6 months" that is a very bad thing in my mind.
Second target (which I got from Beyond Pricing I believe) is 30% occupancy 90 days out. I rarely have any bookings outside of 60 days but its nice to have a few in there as a safety net.
I use Price Labs too, but it lacks good occupancy targets and uses a green light, yellow light, red light system to alert you when occupancy drops too low. I try to focus on raising prices as high as possible on days with high demand. Just doing a blanket raising of prices across the board doesn't make sense to me, as you watch overall occupancy drop.
If your weekends get booked up quickly but weekdays are slow to book, keep prices the same during the week and raise them on the weekends. Pricelabs is so customizable you should be able to learn your market over time and maximize your revenue without leaving a bunch of days unbooked.
