If you want traffic today then you need to do something about it. you cannot just expect to throw up a website and have people visit it. You need to ask people to visit your site.
1. My absolute favorite way to get traffic is by writing articles. Just do a search on google for submit article and you will find many sites where you can submit your articles.
2. Blogging. Many people like to read and post blogs. Start a blog about your website as soon as possible if you have not already started one. Blogger.com and wordpress.com are amazing. Some new ones are squidoo.com and writingup.com.
3. You can purchase advertising using adwords. This can be expensive, however it is easily the best converting traffic you can pay for if used correctly. I highly suggest buying an ebook on adwords before diving in and wasting your money. Here is the best ebook you could buy: Adwords Miracle.
4. Making a list of emails. This can be difficult but if you never start one then you will never have one. The best way to do this is using an autoresponder. What you will want to do is sign up for an autoresponder and then factor it in to one of your webpages. This way if people like what they see they will leave you their email address so they can get more information.
There you go, good luck in getting some quality traffic. Make sure if you decide to use adwords that you don't go about it by yourself and you buy a book dedicated to adwords so you can at least learn the basics.
