Friends,

Just for the information sake:
SEO are specialized techniques used to optimize your web site, to be Search engine friendly and increase your chances of placing well in search results.
Without proper optimization, the chances of placing highly in Search engine results (SERPs) for the keywords important to your business, are low.

or simply, SEO is a way of promoting your site to get a high PR or to be a top listed site on search engines.

Search engine optimization (SEO) is the process of improving the visibility of a website or a web page in search engines via the "natural" or un-paid ("organic" or "algorithmic") search results.
