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.
WordAI is probably the most famous content spinning service. Many people swear by it and the quality of the content it produces and it is not empty talk. But let’s see how it will spin my short story. WordAI has two modes of spinning – “Standard” and “Turing”, with the latter being the one that produces better results. I will spin the text with both of them.
The content above is 98% unique according to Spin Rewriter and I really like it. It actually seems better than the WordAI spin – only the “Standard” one however, it is no match for the “Turing”. One thing that the spinner failed to recognize is the “green eyes” phrase where it replaced it with “environment-friendly”. Yea, I laughed too. Anyway, here is the spintax for those interested in more testing:

But it is the most important that the spun text, especially with version 2.0 usually passes CS test, and Google cannot even see it as spun content. Such as content can be used for links building as well as on money sites and qualitity is pretty good, as you saw in the example. It is much better than other article spinners with similar pricing as they do not get the right meaning of each and every word, so the rewrites sometimes looks funny/strange. It is of course much better than any free article spinner/rewriter I have tried.
Words have the uncanny ability to create magic. Often a group of words is rewritten to achieve various purposes. Either if you are a student, blogger, author or writing in any capacity; you need to play with your words to create magic for the reader. Rewriting is a very useful tool for a lot of people. The best way to rewrite something is to do it yourself and with your own knowledge. Often this is restricted by lack of time and vocabulary. It takes up to hours, days or even weeks to rewrite something depending upon the length of it. No matter how good you are in the language, there comes a point where your knowledge starts to drain out.

Anyone will can this, all you want is a fabulous computer and the flexibility to sequence a post title together. You can generate original article content and submit them to story lookup directories and receive paid for. You possess to apply to these web pages and may or may never get transformed down. If you should materialize to receive transformed down subsequently just hold plugging apart until you obtain person to "work with" you.
Other article spinners also require that you enter your own custom synonyms manually or individually approve lists of potential synonyms as they are presented to you. This is another way of expecting you to do most of thinking, as opposed to expecting the software to be smart enough to instantly make judgment calls for you. Thus, one of Spinbot's main goals is to make the article spinning process as quick and painless as possible.
