Comment on Duplicate Content Penalty SEO by Ryan.

Duplicate Content Penalty I work for a mid sized online retailer and I articles to the website about featured products. The company also has a blog that I work on where I mostly put unique content. However, in some instances I duplicate the article from the main website to the blog website (different domains)

The ratio of unique content on the blog to duplicate is about 8/2. Will this hurt either or both pages? Thanks.
