Actually I have a different view than @Emiel1 on this. Having had a brief look at your listing, I think there are some things you can do.
Before I start @Marian146 , you need to go into your listing and change your price settings, so there is an additional cost for each guest. Your base price also looks rather low for a house that big, even for low season. Look at what comparable places are charging locally. Ignore Airbnb's suggested pricing. Add in a cleaning fee.
You could paint a better picture about your home in your listing. You don't even mention you are in Northern Ireland 🙂
You have photos of a lovely beach and sea, but don't mention it in your introduction. How far is your place from those views. Can you walk there?
Talk about the sort of guests your place is most suitable for. Families? Business People?
You haven't filled out any information about your property - has it got a sea view? What key amenities does it have?
Can you walk to a local pub, places to eat our or shops, or will you need a car. How far is the nearest town what amenities does it have.
Also you have no profile completed. Do fill that it and let people know a little about you and why you started hosting.
I would try and redo your pictures or at least edit them to them brighter and warmer, pending getting new ones.
Perhaps dress the listing a little; with some photos/pictures of local attractions such as the coastline and Giant's Causeway, maybe some bright cushions, books on a shelf. throws and some ornaments or key pieces to help the guests see themselves staying there. Set the table so people can see themselves eating there, and have a few pieces out in the kitchen in a bright colour such as canisters and storage jars with cooking utensils, and some cookery books, so it looks like it is being used.
Here are some other listings in your area, to give you ideas of how other hosts are promoting themselves.

In terms of priority order - the photos of your bedrooms to come in the top five not right towards the end. Put your best five photos first - views, bedrooms, kitchen. eating area for example.
Maybe have a tray set for tea with some soda bread, butter and jam if that is something you could offer your guests.
Anyway just a few ideas, hope they help.
