The most basic tool for an online business is a website, but just having a website is not enough.  You have to know how to use your website to get traffic and turn those visitors into interested prospects.

• Your Website / blog
• Content based on relevant keywords
• Optimize the content and the web page for the search engines
• Use Facebook and Google+ to create back links
• Traffic to your site finds more relevant content and looks around
• You have something to offer your visitors, a free business building email, a relevant PDF, a link to an online presentation.  Something that will create an interest in what you are offering
• I they like your presentation, then you have a chance to introduce them to your company or product and maybe they will sign up as a distributor or customer
