I assure you that one can find this kind of question in lots if internet marketing forums, you will find endless debates on whether replica of a content is a problem or not. You might also have doubt that will your site get penalized if you carry duplicate content? If so, is it ok to write an article, put it on your site, and then spread it to article directories and web 2.0 sites? Or do you have to rewrite every single article to make it unique? This is a critical question because rewriting articles takes a very long time. Spinning them takes some effort as well, and the results are usually not very good (to say the least) and it turns out that a lot of people work hard to get unique content on each and every article directory and web 2.0 property in order to avoid the much-feared “duplicate content penalty”.
The question have been asked to one of the Gurus who follow some good strategies “Is it ok for me to take one article, put it on my site and then spread it all over the 'net to get back links? He just responded with “It depends”. He tells the reason behind that. If your content is all over the web, it is hard for Google to figure out who is the authority who originally published the article. Since you want that authority to be you – you need to make it clear to Google that you are indeed that authority and your site should be ranked accordingly.
However, if the entire articles link back to your site then it is clear to Google that you are the authority and your site should get the credit by getting a higher ranking. So according to the strategist it is ok to have duplicate content as long as the other articles link back to you. That means that if you spread your article around (this is called syndication) to article directories and web 2.0 properties (and other places as well), make sure that they all link back to your site. That establishes you as the authority and source for the information, and will cause your site to rank higher. It means to Google that what you wrote is respected and valued by the other sites.
By linking to you, they are giving you 'points' and saying to Google that you are an authority on the subject and one more thing: The Strategist also suggest that we need to put some extra efforts in the article that we put on the main website so it will be better to put some extra content on your page. So take the article that you have and post it everywhere. But the article on your own site should have extra unique content that is not found anywhere else. So it’s all your choice whether you need to use your own articles everywhere or different articles that are not going to simple for any one.
