This is a great way to promote your business, and get yourself established as an expert in your field.  You can submit articles to websites (such as here & other sites relevant to your industry) as well as to offline publications such as magazine's and newspapers.

Before submitting articles,

With free reprint articles, create a bio for yourself that includes the URL of your site.  This way people can easily find you.

You can also submit your site to article banks such as www.therepozitory.com.au (for Australians) or www.greatarticlesformoms.com (US & Canadian content mostly).  These are free to join and enter content.  You can also get articles for your sites or e-zines free, so long as you include the author's bio box.

Article Marketing is a great way for Mums to promote their businesses, because all it takes is time.  Write your article, submit it, and let other's republish it and help spread the word about your business.
