If you post this topic to most of webmaster forums, those so called seo expert or claiming their self as seo expert will tell you that if you copy other sites content and put it in your site for sure you will be penalized by google for duplicate content.

They always insist this theory, but if you asked them what is their prof  that the site using a duplicate content is penalized by google they don’t even show you any prof. In my own opinion unless you don’t use same content in same website google will not penalized you for a duplicate content.

I know this because I’ve doing this for  more than 4 years and I have never experience this so called duplicate content penalty.

Why should they penalized sites with duplicate content and why they hate them if they (search engines) also displaying duplicate content on their sites. Directory sites, social bookmarkig sites, rss feed directory sites, and article directory sites are all using duplicate content but why they were not penalized by search engine?

As long as you present a good and quality content to your visitors, I don’t think this is not right. As they always told, create a content not for search engine but for your visitors.

For those who like me who have trouble creating their own site or blog because they don’t know what to post on it, don’t be afraid use free articles or PLR in your site they are still considered as quality contents.
