Don't take steps to make your website popular before posting atleast 50 articles. If you are a amateur blogger, first concentrate to post quality articles. After posting 50 + articles you can surely get some decent traffic. Set you target as 100 visitors per day. When you reach your target take steps to make your blog popular.
If you try to make your blog popular before posting enough articles to your blog you will lose consistency and visitors. Just imagine that you are opening a shop and your shop has got no products and simultaneous your shop will be marked as useless. Blogging is similar to it, make popular by quality articles and you will gain unique visitors.
After fetching decent traffic just with your organic content start Facebook page, G+ page etc. Regularly update on those pages. There are many bookmark sites like Reddit, indli, Stumble etc.
You can use Yahoo Answers to promote your site. For example: You have written an article about "What is LED?", there might be some users who asked the same question in Yahoo Answers, there you can explain something about LED and put your website as reference.
Use Facebook groups to promote your blog. Usually some users may ask questions in FB groups and there you can submit your link as reference. Don't spam by posting your link to unrelated question.
My advice is concentrate only on post. Don't rely on useless tricks. If you are providing good contents to your audience you can surely get high traffic plus popularity.
