These days there are a lot of article rewriting softwares and it is pretty hard to choose one that will suit all your needs (quality + price – no subscription at least). When you will look for example at WordAI article spinner – you will notice that there is pretty expensive subscription (50 dollars per month) while spinnerchief costs only 77 dollars per year (which is about $6.5 per month).
4. Tier 2 content (content that is keyword rich and relevant to your niche. Doesn’t have to be all that readable, it just has to be indexable by a search engine.)– Here put same options as with the Tier 1 content situation with the only difference that you set the 1st input to “Regular.” It is important that lower tiers have a lower quality of content compared to upper tiers.
I first met Aaron in Washington at Yanik Silver’s event & he was extremely humble about his seven figure tool product that had been quietly making affiliates a lot of recurring income. Over a webinar I grilled him on the pitfalls of spinning, only for him to reveal his high traffic guitar site built using content from Spin rewriter which was clearly useful to its reader. As he demo’d the tool I could see it was by far the most powerful tool out there. It is a perfect product for an I.M or SEO list.

I've ranked websites in the past with spun content, and now they are still on #1 position of google. First year (2014) google found me because my spun was really bad, many paragraphs were just copied and my position drop from #2 to around #20 after a panda update. Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
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.
