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.
Some favorable aspects to writing articles and marketing them on the net is that you really get to supplement your monthly income. In this challenging economy who can't use a few additional bucks? Another upside is that one may build up your cache of first content and increase your reputation for writing and possibly pull some higher paying customers. Lastly, merely think about the information you're gaining by having to research some of the subjects you write about. You're, or will shortly be, a fountain of worthless tips.
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.
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.
