Article Marketing Goals

Writing articles about your niche and keywords is a way to give your web property targeted trickle traffic.

Concentrate on posting to the highest PR sites.

Get a couple few dozen out there as soon as possible.

Use Google Analytics to track the incoming clickthroughs from each article.

If you wish to not spend money on viability testing of the marketability of a product through PPC, then upload a few custom articles to various sites to see what interest they generate.

Articles that point back to your site may have a modest effect of increasing your search engine rankings since the backlinks to your site have increased.

You may be better off writing guest posts for other blogger rather than writing articles that are uploaded to article directory websites because you'll get more exposure and credibility that way.
