Hello, this is my first post.
A while back I purchased a content site with 16,500+ html articles. There are 155 sub-domains that act as individual web sites. Topics range from Acne to SEO, and each topic has better than 50 articles at least.
While this is a ton of content, it is also unoriginal content. This is going to make it very difficult for me to get ranked on search engines. Major search engines such as yahoo have been said not to even accept websites that contain content that is already vastly in their system.
However, I have come up with an idea that should help my odds, and I think you should consider this as well. I've decided to add original content to the sites mixed in with the content that was provided to me. For instance, I own a forum for car enthusiasts, so I have been taking technical discussions and turning them into articles on my new site and giving the original authors credit for them, as well as a link back to my forum at the bottom of the article. This should help my search engine placement in a huge way.
If you're looking for pre-made content, you can actually purchase content websites for very cheap on Ebay and use the content there. However, beware that the content you are purchasing is very unoriginal and could be floating all over the web already which will always hinder your abilities to rank on search engines. Original content is always best!
