That’s really weird. I have tested WordAI and Spin Rewriter with Copyscape and the results were always 80%+ uniquness, even 90%+. I don’t know how u spun the content to achieve such low results, but this is definitely way too bad. As for the block spinning, I have to be honest, this is the first time I’m hearing of it and I will have to check it out when I have a bit of time, but generally, yes, in the best case scenario, you would manually touch your Tier 1 content to make it 100% human readable and as unique as possible. For lower tiers, you can do pretty much anything, but again, the better quality of content, the better results you will have. That’s in my opinion and experience.

Not so long ago there lived a boy. He blue eyes with blond hair as yellow as gold. The young boy was smaller than average fragile, but his mind was swift much like the wind. He could calculate the outcome from a situation within the blink of the eye. But that was not his biggest talent. No. His biggest talent was perception. The son could understand and perceive anything quicker than anyone he’d ever met. Then, he fell crazy about a lovely princess. She’d magnetic green eyes and light brown hair. He loved her quite definitely and then she loved him back even more. There were only 1 problem – the young lad was the son of your blacksmith. The princess’s father would never allow her to marry an easy son of a blacksmith. On the other hand love was too strong. In a single fell swoop, the young boy raised an army of undead and commenced a rebellion to overthrow the evil king who didn’t trust soul mates. After months of struggling with the armies of his beloved’s father, the young lad was assassinated as well as the war was over. No songs were sang.

Start with a quality article. This means a unique topic or viewpoint on a very specific topic. The information must be valuable to a human reader. At this point in time, it is not possible for any software program to produce content that is engaging. If you start out with a low-quality article, the chances are high that the alternate versions are going to be even worse.
For many years people used article spinners to mass produce unique content from one source article without really thinking about the quality and the human-friendly flow when it came to a real human having to read the content they landed on when visiting the website. Much more emphasis was put on producing content that was purely made to fool the search engines and rank the website accordingly.
To rank your website in search engines you have to post content at your website on daily basis. If you have more than 2 websites then it is almost impossible to write unique content on all those websites. To do this task webmasters use article spinning tools so that they can post articles to their domains daily. Paraphrasing Tool is also used by students when they have less time to submit their assignment; they just copy content from the internet, rewrite it, remove grammar mistakes and submit it.
