Important Note: A few article directories like ezinearticles.com (the best article directory) do not allow you to put affiliate links in the author bio/resource box section. Please check the rules and guidelines before submitting your articles.

In case any article directory does not allow you to use your affiliate link, you may set up a free blog at blogger.com or wordpress.com. Promote your affiliate link in your blog. Then you put your blog link in the author bio/resource box of the articles you submit to ezinearticles.com and other directories with such restriction.
