What type of product or products do you sell?  Who is your ideal customer?  Do you have an email list?  If not you need to start building one. Your customer needs to know who you are. Business is very competitive today.  Go to other blogs where you think they are hanging out. Try commenting on posts. Have you taken any ads?  So many questions need answering before you can pinpoint where you are going and what you need to do.
