Search engines attempt to avoid indexing multiple copies of the same content or duplicate content. Many search engine optimization experts hypothesize that not only does a search engine not index such pages, but it also penalizes a site for having the duplicated content.
This is a subject of much debate, but in any case, having duplicate content will not improve the rangkings of a site in any of the major search engines. Therefore, duplicate content should be avoided.
