How to get traffic/buyers to my website?

[AutoFace 2.4]

i want to start my own online business website, however from reading forums and other sources online, it seems the common problem with people trying to start an online business is getting people to actually find their website and click on it, with the massive database of websites within googles search engine, i could understand how ones website can become lost in the infinite world of cyberspace. So just how does one become get their website noticed? get clicks? get buyers? im a complete beginner on this subject of e-commerce however im quite good at finding what products are in demand, which is why i want to create an online website in the first place where i can reach more people. Does anyone have experience in this field? what are the necessary steps of creating and promoting a website? any help would be much appreciated. Thanks!
