Networking

Just like in the outside business world you need to network to make your business happen. Whether you are running a website, working in direct sales or even if you have started your business from scratch. It is important for your business and for your personal wellbeing to get out and talk about it. You can network online and offline. Talk to your family and friends tell them about your business and give them some business cards. If you get them excited they will talk to their friends or inevitably they will have a conversation where whatever you specialize in comes up. People everywhere need or want whatever you are selling. They won't know you have what they need though if you don't tell them.
Online, find websites that compliment yours, if you are selling baby rattles you will want to frequent and join message boards at parenting sites. Some places will let you post your link in your signature line and others will not, make sure to check. Just by being there and getting involved in the conversations though will give you opportunities. If someone says, "hey I am trying to find a very special baby rattle for my sisters baby shower" you can always send her a private message or possibly email her with your web address. Don't take this to extremes. If you are sending emails and pm's to every member of the board you will sabotage yourself. Only offer your business if it is asked for.
