Well, I guess you should start with writing a blog post over you own blog and then start promoting it over the social media, best would be creating a facebook or google page and then post it over to your page this will help you in creating interest among the user and you can get good conversion out of it ! As well as if you are good with your blog it will start getting ranking over the serps just make sure that you don't write for the sake of writing try to share information which is not available with the others or I would say experiment with something different and you will be good to go.
In addition to make a blog on your own site, you should also start making blogs on some web 2.0 sites like blogger, wordpress and many more. You can write articles and add your website's link in these web 2.0 sites and make a network of these sites. The bigger your network the more exposure your website would get which will eventually lead more traffic to your website. But always remember one thing to always use original and unique content.
