Most search engine marketers realize that search engine marketing is getting a mass amount of traffic to one's website, for as low of a fee as possible. That is what search engine marketing is all about. Whether you use search engine optimization, which is the science of tweaking a website so that it comes up higher on a search result, via the natural search results, or paid search engine marketing, where one is using companies like Overture.com or Google Adwords so that their site is listed alongside the natural search results. It make no difference, the bottom line is getting relevant and massive amount of traffic to one's website, for the lowest fee possible.
