Hi Louise and Jim,
It's been really slow for me, too, and I can't figure out what's going on. I have one booking for May and none for June. Usually by this time of year (I've been a host for 4 years) I'm fully booked for June and July.
Some thoughts: most of my guests are European and there is economic struggle there now, maybe Airbnb's change in service fee for guests from 8% to a sliding 8-12% is making my listing more expensive or maybe there's more competition?
Depending on how new you are, you may not get as much traffic to your listing until you have a lot of reviews.
