Are the articles that are spinned by article spinners like JetSpinner will not be traced by Google as duplicate content? Will Google penalize my site if will be using spinned articles for my website contents, blogs, and articles?
Google cannot penalize your site just for this because this will make our competitors very easy to pull us down I believe as long as every sentence in an article is different, it is a different article. Which is easy to be done nowadays.. good luck!
While you can avoid the duplicate content filter using services like JetSpinner, the quality of the articles will be just awful.
i've been using jetspinner myself these days and it does a great job. if you use the syntex and word variation properly, yuo will get a good output and no way google can know its a spinned article. it will be just as new as a human written unique article. but remember, your output depends on your input
