Article marketing is a type of advertising in which businesses write short articles related to their respective industry. These articles are made available for distribution and publication in the marketplace (there are products available that automate this process). Each article contains a bio box and byline that includes a link to the author's affiliate website. Well-written content articles have the potential of increasing the trust factor of your site, attracting new clients through direct traffic and improving the indexing of your site. In some cases it can improve your ranking through backlinking.
