Article marketing is one of the most common practices for SEO today, though it has been already exercised even before the birth of the computers and the Internet. In a simple manner, it can be described as the publication and distribution of written piece using the traditional (paper-print) and online media (the Internet) to reach the marketplace. Usually, its content is related to the industry of the author as it aims to boost the company's reputation, and at the same time, advertise and promote one's products and services. Whether you are writing an article for paper-print or for online publishing, make it sure that it is informative and powerful enough to gain good readership and somehow, convert it into sales. However, articles which are meant for online distribution should be also optimized not only for search engines, but also to human readers, which is the most important thing.
