Here is just the intro:
Search engine optimization (SEO) is the process of improving the volume and value of traffic to a web site from search engines via "normal" or un-paid ("organic" or "algorithmic") search results as opposed to search engine marketing (SEM) which deals with paid insertion. In general, the higher a site appears in the search results listing, the more visitors it will receive from the search engine.
So, you can already imagine if you have a blog or website in the niche of insurance (I used this example because a friend of mine asked about it), first you'd want to go deeper into the niche. This means focus on "car insurance" rather than just insurance; so if your blog is on car insurance, and every time someone typed in car insurance in the Google search box, good SEO practices would allow you to be on the first page of the natural listing results (the picture below shows an example).
It is definitely a great article with a huge tip in the end. Read SEO Marketing Strategy here...
