Article Directories
Article directories are sites that can be considered content depositories for webmasters.
What happens is people write informative articles that a webmaster can use as content for
their website. In return for their efforts, the webmaster must keep the article intact,
including the most important element, the link to the other person’s website, (usually
found towards the end). So, when you write for an article directory, you are getting: 1) a
definitive one-way inbound link from the directory itself, 2) traffic from webmasters
perusing the article, 3) possible one-way inbound links from webmasters that decide to
use your content and 4) possible traffic from the sites of these same webmasters.
If you decide to write for an article directory, it is best to make it keyword-optimized, as
if you were writing content for your own site. You will also want to try to make it at
least 400 words. By doing both of these things you increase the likelihood that a
webmaster will choose your article as content for their site.

this is easily the best marketing that one can do.

it will bring traffic for a long time to come.
