Hi @Daniel13183
As @Helen3 points out, if you do well on other platforms, your calendar is blocked on Airbnb for those reservations. This naturally reduces your visibility for guest searches on Airbnb, since those dates are not available and guests searching will not even see your listing appear.
I echo @Marie8425's point that you need better photos. The best investment you can make is to get professional photos done. You will see more more bookings and the cost will pay for itself. It's the best ROI any Airbnb Host can make. You have a gorgeous lake view, but looks like many of the photos were taken on a cloudy, rainy day? Your cover photo is especially important and should highlight your best, most unique feature. The one you have now doesn't really do that. The current photo appears quite a bit tilted as well. See if you can at least straighten the photo by editing it. Try to hire a photographer who is experienced working with Airbnb's. Drone shots are done by most photographers and I think a twilight exterior photo that captures the home with all the lights on and capturing the lake view would do wonders for your bookings.
