SEO is search engine optimization and I would recommend anyone that is working a business online become familiar with it.

Without atleast a basic understanding it is going to be difficult to create sales.

Many people think you can simple sign up for a online business opportunity, get a website and start earning money. It does not work that way.

You can have the beast website in the world but if no one knows it is there then you will not sell anything.

This is a HUGE problem with many online "opportunities" and the main reason people fail. If you cannot get traffic then you will not make sales.
