     The absolute best method that I have found to promote your product or business is to write articles and

post them all over the Internet.

     Webmasters and publication editors are always searching for well researched and written articles that are

relevant to their websites or publication themes. This creates a profitable opportunity for you. Editors and

publishers don't have a strong need for good content. Each issue they publish must be filled with valuable,

usable information that will appeal to their readers or subscribers'(订户) self interest.

     By writing and sending articles to the various websites and article directories on the Internet you will

establish yourself as an expert on your topic of business, as well as gain the trust of your readers over time.

     As a result, your readers will be eager to buy your products and services or those you recommend to

them. This is a very effective way to make name for yourself online. Articles can also build your link popularity. This is extremely important with search engines. Every time your article is published there should be a link

back to your sales page where the reader can go to get more information. This will help the search engine

ranking of your site. When website owners list your articles on their websites, your business exposure can be

unlimited.

     Make sure your article provides information that is really useful to the reader. Make it interesting to read.

Get to the point quickly. Use short paragraphs. If it's dull and boring, your reader will surely move on.

     Make sure you add a resource box at the end of your article. Use your resource box to promote your

business. This is why you've written the article.
