It basically all boils down to a) having an item that people want b) a great photo to attract potential buyers to click on your listing and take a further look c) a competitive price if this is a fixed price Buy it Now listing and d) a title featuring relevant keywords because this is how your buyers will search for your item.
If your listings meet the above criteria then, to be honest, you're listing items that now have a very small buying audience.
Just a heads up - the multiples of new items you have listed will put you in the business seller bracket, so you may want to upgrade this account to a business one and open another for your own personal items that you're selling off.
A Business seller is someone who buys or makes and item to sell on. They need to be registered as a business to meet the requirements of UK law. They need to declare income to HMRC once they reach £1,000 worth of sales (eBay will be providing HMRC with your details anyway so it's vital to keep correct accounts for your tax return). You can obviously offset more expenses as a business seller, but can't offset any at all as a private one.
To correctly register as a business seller simply go to your Personal Information in your account and to the right of Account Type, which will be showing as 'Individual' you'll see an Edit option.
