There are a million and one things that have to be taken care of with your website in order to for it to be successful in the extremely competitive online world these days.  You have to make sure that your website has more than what the other guys have, because in reality, rank isn’t the only thing that people look for in a site.  What they want is to hear that little “Click Me” voice in their head when they look at your link when it pops up in the search engine.  You’ve got to provide them what they want and need, which is quality, relevant, content and more, to entice them to come to your site over all the others.
