I didn't open the link but it's totally common ! When you're just starting out, it can take a while to get a few bookings..and many folks don't leave a review.
If you check our account, we started out in Jan. 2024 and haven't gotten a lot of reviews/bookings through airbnb. However, we live in a small town with not a lot going on here to draw Guests 🙂 But..we have had Guests from locals (wedding, funeral, graduation, festivals) that booked direct from us. We also used VRBO and Booking . com so there were bookings at those venues. There is currently a large work facility that is under construction in town and we have hosted a half-dozen different workers for temporary housing. Airbnb is just part of the story..
When Guests find us by being referred from the Visitor's Bureau, they are happy to have saved money by booking direct. In turn, they tell their friends 🙂 Word of mouth is a great way to be found.
