To attain visitor traffic to your website you must understand how traffic flows throughout the internet. This understanding stems from the basic algorithm of the Internet and the goals of it's original creators. The goal of the creators was to link the knowledge of mankind together by using hyperlinks. You can be on one page of content and click a link, to be sent to another.
Links point to sites or pages of similar content.
The Internet grew and became what is today because of a simple basic goal, but we are leaving that basic premise by relying on search engines to move traffic to our websites. What we have today has become a quest to store all the knowledge of mankind into search engine databases. This is unnatural to the way the web is designed and should be used. Trying to store all the information in a giant database, doesn't work and never will. Results are diluted and the knowledge grows faster than robots can index it.
