If you have a website or blog maybe will not mean anything as good as any design that you created when none of visitors coming to your blog. Say you have paid a very expensive one so well-known web designer of your web design look "perfect" then you fill it with interesting content. But it will only be in vain if you do not ever do promotions. I think without campaign or some promote will be very difficult to get visitors. Yeah, how do people know anything as interesting as the design and content web / blog if you do not promote it. Except, if the web / blog is long enough so that indexed by search engines. But keep in mind that not as easy as that search engines will find web / blog. It might be a lot of web / blog content as competitors with the theme of your blog earlier indexed search engines so that your blog neglected, or at least not on the front page of search results.
This is will increasingly become a problem when you are wrestling in the world of online marketing, or other online business. Of course you expect your product as soon as possible (if you sell products through the web / blog), known to many people so that they are interested. Or in other online business, where website traffic is critical reap dollars. That is the importance of traffic to the web / blog. And to get good traffic you have to do promotion, in addition to other SEO tricks. As an indicator of the quality of traffic there is a site that provides traffic to the website / blog, namely through alexa traffic rank. for more detail you can visit here: http://glodhog.wordpress.com
