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.
Having struggled flat broke for 4 years in IM before I made it, I know better than anyone what it's like to never see success. I know what it's like to keep failing over and over when it seems like everyone else is succeeding online. The good thing is that I never gave up, so here I am, who know how to make money online wanting to help you achieve what I did... MUCH faster than I did. Hey it's Leo. I'm a sort of an optimist. Survived internet marketing, wonderful wife, have 2 kids. My wife would say I'm a night... I think morning. Enjoy travel, spend times with friends. Go out to parks, fishing and watching football and trees (treekeeper) are the things that I love to do.
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.
