From Judy Cullins, http://www.BookCoaching.com:
You can build a huge Web presence and be in the top 20 listings in Google and other search engines by submitting your articles to top web sites in your field. Many sites such as www.ezinearticles.com offer authors many categories--business, personal growth, women's issues, parenting, food, writing & speaking and health and fitness. They publish your article to give their visitors new content, and you get Web visitors to the site where you sell your book from people who appreciate your information. Your Bookcoach started by submitting to 10 Web sites and now to more than 100. Each submission takes less than 10 minutes. This promotion technique is great for reluctant marketers and introverts.
