DupeFreePro is a free software tool that helps you avoid using duplicate content when you’re posting articles here and there on the Internet.

 As you may know, Google ignores duplicate content with it does its magic to decide your SEO ranking.   If you post the same article (containing a link to your web site) in more than one location,  when Google calculates your web site’s rankings, it uses what it considers to be the first posting or the earliest article and ignores the others.

For optimal results, you want to rewrite the article enough so that Google perceives it as original content. This can be tricky, since it’s difficult to know when you have modified an article enough to rate as new content. 

DupeFreePro solves this tricky problem for you, and a few others as well. DupeFreePro will tell you if the two articles are sufficiently different to be considered unique. It will also give you a keyword density rating so you can be sure your keyword or keyword phrase appears the “right” number of times. Additionally, it suggests other related words that Google expects to find in an article that contains your keyword phrase. For example, if you are writing articles optimised for the keyword phrase “how to make a diaper cake”, DupeFreePro suggests you incorporate related words such as nappy, baby, baby shower, etc.

You can use DupeFreePro to be sure your rewritten PLR articles are sufficiently different from the originals; you can use the software to prevent accusations of plagiarism if you are using material you have researched online; and lastly, you can use it to optimize your articles’ keyword density for the search engines.

I find DupeFreePro a good program, although the number of times it expected to see my keywords appear did seem a little excessive. Perhaps that is because I had been underusing keywords before. 

DupeFreePro is freeware and its a good product. I have no idea why the publisher is giving away an application that he could obviously sell, but no doubt he has his reasons. The sales page — quite unnecessary for a free product — suggests that the software will be sold at some point.

It’s a good help to anyone who uses article marketing, PLR articles, Squidoo lenses, HubPages, blogs or similar. I suggest you get a copy if you’re interested in avoiding duplicate content on the Web.
