A long time ago right now there lived a boy. He had blue eyes with blond hair as yellowish as gold. The young boy was small and fragile, but his mind was swift just like the wind. He could calculate the outcome of any situation in the blink of an eye. But that had not been his biggest talent. No. His biggest skill was perception. The young boy could understand and perceive anything quicker than anyone he previously ever met. Then, he fell in love with a beautiful princess. She acquired magnetic green eye and light brown locks. He loved her quite definitely and she loved him back more even. There was only 1 problem – the young boy was the son of a blacksmith. The princess’s father could not allow her to marry a straightforward child of a blacksmith. But their love was too strong. In one fell swoop, the young boy raised an army of undead and began a rebellion to overthrow the evil king who did not believe in true love. After months of fighting against the armies of his beloved’s father, the youthful boy was assassinated and the battle was over. No songs were sang.
Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
It looks like the creators of Spin Rewriter 9 .0 have really put a lot of work into creating a piece of software that creates readable content. However, Google isn’t stupid and there are a lot of things that can go wrong when you are trying to “manipulate” Google into giving you more traffic. Google hates spam, badly written content and duplicate content. These are all things that Spin Rewriter 9 .0 is capable of creating. You simply can’t trust a piece of software to write content for you in my opinion.
