Article marketing still works, but not as much as it used to.

Seeing that submitting articles has been used to get more links
to websites, the Search Engines seem to discount the weight of
these links.

No-one specifically "voted" for this website, and so it's only
logical that the Search Engines count true links from website-to-website
more than a link from an articles directory.

Still, you'll get traffic by submitting to the Article directories.
