How many ways do you think there are of saying the same thing in 1,000 words? Certainly not as many as your imagination convinces you and certainly not even close to what we need. Most people use content spinners to generate content for GSA SER projects and other similar link building tools, which require thousands of unique versions of a single piece of content. I guess the reason I tell you all this is to make you understand that the content that is generated by modern content spinning tools is not bad at all when you consider all these facts.
Article Rewriter is a software or a human ran service that rewrites articles for you. Before the development of Machine Learning and Artificial Intelligence, there were humans that used to provide this service. There are some human rewriters out there today but they are not efficient. There are tools like WordAi(https://wordai.com) that uses artificial intelligence to understand the text and is able to automatically rewrite your article with the same readability as a human writer. WordAi rewrites articles within minutes (if not seconds).
In this day and age, it is by far the one of the hardest tasks to do online always coming up with fresh content for Google to devour. I love how easy Spin Re-Writer makes it for online marketers to get on with their business and not have to worry about the big G penalising their sites. Of course it's not just about fresh content, but it is certainly a big factor. Thanks Aaron and the team...:)
