Anyone can do this, all you need is a computer and the ability to string a sentence together. You can write original articles and submit them to article directories and get paid. You have to apply to these sites and may or may not get turned down. If you should happen to get turned down then just keep plugging away until you find someone to "hire" you.
Spin Rewriter 9 rewrites content on paragraph, word and sentence level. It also turns sentences around and makes sure that only appropriate synonyms are used. Aaron added a special ARTICLE GENERATING ALGORITHM to Spin Rewriter 9.0. This algorithm makes sure that the generated articles are even more unique, and even more readable — if that was even possible!
And then there is the amount of time that it takes to create content with this software. I have had past experience with text spinners and although it might seem like a fast way to write content, it often isn’t! By the time you have chosen a piece of content (or multiple pieces of content to blend together), put it in the software and produced content with this software, you could instead have created content that Google loves.
