I downloaded the beta of Spinnerchief III. First thing I found that I did not like was that it was wrapped in Whitehat box. So I unwrapped it by finding it and moving it to its own area. It runs without the wrapper.
I then downloaded a 300 - 350 word article and spun it. The article had three quotes. After several hours of work, I ended up with five articles that only had 27% similarity.
I ran each of those articles through the plagiarism detector at Small SEO Tools. The best article was 73 percent unique, the worst was 50 percent unique. The problem was the quoted sections. I used the 73 percent article as is because it was going into a blog that added about 300 words to the article and the quote would link back to the article where the quote was made or the Senate bill that was referenced. This article was posted and began ranking on page five for certain keywords and page one for others within three days . This is among some big players like the Direct Marketing Association, The Hill, and several high ranking privacy blogs. This article was placed on a PR 2 blog that is two years old and has a foreign tld.
I then took the best two of the remaining articles and ran them through Small SEO Tools's plagiarism detector and worked with them until they were 100 percent unique and posted them on two other blogs I am working on for a client. These blogs are about 6 months old and are not yet ranked. I placed those articles yesterday morning. One of them is ranking for one of the keywords this morning and the other has not yet been indexed in Google.
While I have used Spinnerchief for a while, this is my impression of version III. Version three beta needs help. It does not crash so much as it hangs. It especially hangs when there are other .net programs running in the background. Most of the hanging appears to be a poor implementation of multithreading and thread locking. Most often, if you give the program time, it will correct itself, but not always. The cloud thesaurus needs more synonyms. I had to go to Thesaurus.com more than once to find appropriate synonyms. You have to generate far more articles than you need to get relatively unique and human readable articles (if you consider 27 percent similar unique). I had to generate 150 articles and then spend about an hour comparing, editing, and eliminating articles to get the five above.
Many of the hangs occurred when I edited one of the articles. This suggests a memory error. Spinnerchief also does not autosave. If the program crashes and you have not saved, you may be hosed out of several hours of work. That is a huge problem.
It would be nice if SC checked articles against Google for plagiarism rather than rely on another online tool. I greatly distrust online tools.
On the other hand, when used against TBS, I much prefer Spinnerchief because it is easier to use and more intuitive.
One thing that needs to be said, even though it was implied, I used SC to spin articles that went on the money site. If used for tiers 2 - 3, I do not believe that it would have required as much work.
