Right now search engines compete to make themselves better in terms of their results and different functionalities. The more relevant results, the better.
Google has plans of making their search engine capable of tracking real-time information. Now you can see search results update in a moment’s notice – from twitter or facebook or myspace, etc. This is a phenomenal development for the search engine giant and is sure to affect SEO in the coming years.
SEO has no direct, knockdown guidelines on how to make your page rank higher. It doesn’t tell you how to be a competitive site, doesn’t tell you how your site will get into the 1st page search results. It doesn’t tell you it’s secrets. You have to know it yourself.
