I'm still wondering about this... right now I felt like getting SpinnerChief but this issue is bothering me. I've been using Senuke's "Get content" function to let it gather articles and merge into one. Then I used Magic Article Rewriter to rewrite them (with ~50% uniquess) and post them in web 2.0s. I'm using MAR over Senuke's rewriter because it makes the article more readable. After the web 2.0s are indexed, I did notice a tiny bit of increase in SERPs. Now here's the strange thing... when I did this in Article Marketing Robot and did a blast, one of my site experienced a drop in SERPs instead. Perhaps because the uniqueness is only 49-50%. So I'm wondering if I were to get SpinnerChief or TBS and spin them to get a higher unique level, will I have a more positive result? Do share your opinion or at least make a vote. Will Rep.
