I know Google loves original content. I have recently published an article that I haven't submitted to any directories, and it immediately ranked very high for its keywords. Other articles that are posted on article directories are ranking pretty badly on my original website, but ranking some what OK on the article directories. This got me wondering if publishing my content else where is hurting the overall ranking of my website?
The competition is probably an important factor for why some keywords on my website perform better than others, but I still wonder if my suspicion has any legitimacy.
