let me add my 2 cents.

If you're planning to write your own articles and post them to article directories you must take note of the followings since most of the articles directories only accept articles which are good, unique and free from spelling errors:

• non duplicate article
• no spelling errors
• good and informative
• add knowledge/info to readers
• limited embedded urls
• at least 350 words

If you're planning to use PLR articles that you bought, do not copy and paste your PLR articles directly. Rewrite or rephrase those articles to get at least 35% difference from the original articles.

Also make sure you post to the related subject area. Read their posting rules before you post your articles.
