“There is no duplicate content penalty. Google’s major search engine function is to provide a customer the best possible results for a search, based upon the search term (keywords) that the customer has used in the Google search box.

Google’s customers are not:
1. You, who use it to get your web pages listed.
2. Adwords advertisers that use Adwords to advertise their products.
3. Corporations or individuals that use it to have their web pages listed.
4. Internet marketers who recommend others to use Google for advertising or searching.

Google’s customers are those seeking information, whether that is to solve a problem, where to purchase a product at the cheapest price, find a sports result or to get directions to a specific location. Everybody that uses Google uses a search term to find some information that they need. That search term is what you and I refer to as a keyword.

If Google detects several web pages offering exactly the same content, its algorithms will select that which best offers the information required and list that. It might also list one or two other pages offering exactly the same content if there are good reasons for it doing so (e.g. more links to other relevant websites, more other relevant pages on the domain, and so on).

So, not all duplicate content pages will be refused a listing. If these duplicates are articles, then the algorithms that the spiders carry on their backs will take the links from these articles into consideration, the authority of the directory on which it is published, and other factors, before deciding which should be listed. It is wrong to believe that this decision has a chronological factor, but, if you include a link in your article Resource section to your web page that contains the same article, then your page is liable to be listed above the others, partially because of a greater number of links back to it from the other copies, and partially because your entire site is liable to be more relevant than these others to information being sought by Google’s customer.” ~ Source: SiteProNews.com
