There was a time not too long ago when people thought of blogs and websites as two distinctly different things. The purpose of a website was to promote products and services and provide static information. A blog was a type of website that featured articles or journal-like entries that people would bookmark or subscribe to and read periodically.
Today, websites and blogs have a much closer relationship, and frequently occupy the same space. A blog has become an invaluable tool for driving traffic, and therefore has become a permanent fixture of an increasing number of small business websites.
