Ezinearticles.com can be descript as articles market place or portal and this site can generate you lots and lots of traffic back to your web base on the quality of article you write/ post and the niche you selected. The more articles you write to promote your products / niche you have on your site (quality articles) the more traffic you will get. So go and get yourself an account with ezinearticles.com this will give you the basic account meaning you are only allow to submit 10 articles which then the board will review your work (take about 2 weeks for free members) and if you have good quality work they will promote you to Basic plus or you can jump the queue and become a premium member for about $100 a month which give you lots of paid members benefits like in any memberships you join (like review your articles and release within few hours).
Some other ways to get free traffics or web exposed are:
Forum – where you discuss and debate on the niche you select.
Social Network – Facebook or Twitter.
But the best traffic I find is PPC traffic (Pay Per Click) which basically you place an ads through Search Engines and when people click on your ads you paid a fee to your Search Engines where you place the ads with, hence the fee vary pending on the keyword you choose and you only paid if people click on your ads. PPC is a very powerful tool to get traffic and target traffic, though it can do you much good and harm and eat your profit down to nothing without you making a cent. So unless you are sure and confidents of what your aims are, stay with free traffic through forum, social network and eziarticle.com
