1. Article Directories

Many argue that article directories are bad places to get
articles from because of the “duplicate content” penalty
that search engines may throw at you. However, what they do
not realize is that search engines penalize duplicated
PAGES, not content – there is a difference
2. Blogs

Blogs have become extremely powerful lately – search
engines are devouring them. Why? Well blogs are short for
“web log” – an internet based journal. Just the title
automatically indicates that the blog will be consistently
updated.
3. Product Reviews/Information

Many affiliates who sell physical products or have websites
that sell hundreds or thousands of websites argue that they
cannot possibly write articles to promote all the products.
