You have to use spun content. MANUALLY spun! Here's the kicker:
If you spin on one single level (just words) you can generate over 1000 articles from one spintax, however the uniqueness will be around 40% only. Even if you generate just 20 articles uniquenes is still just 40%. In order to increase uniqueness you have to spin multi-level, there's no other way. If you spin on 3 levels - paragraph, sentence, words - you can get in the 70-90% uniqueness range. This takes time and skill to do it right. Spinning is an art and I can tell you from experience most people don't know how to spin multi-level properly. There's somethign that happens when you spin multi-level that will give you same bad uniqueness of only around 40% if you don't do it right. When you spin at paragraph or sentence level you don't just use synonyms of the stuff int he original sentence because that produces same output as if you had it just 1 level. Don't know how to explain this better, i hope you understand what i mean. You basically have to rewrite the whole paragraph or sentence in a very different way. For example you can change the idea completely. For a paragraph that basically states that "X is a great pill to loos weight and make you look better" you would rewrite it into something along the lines of "If you're not feeling confident because you're over-weight, X can help you loose weight and feel more confident". In one paragraph the idea is you don't look good, in the other is you don't feel confident. Both can be interchanged.
Also keep in mind that all spinnign software reports an incorrect uniqueness. If the software says it is 100% spun it could in practice be just 30% unique when you spin it. Why? Because the algorithm they use is not the right one. The right way to compute uniqueness is to compare every single generated article with every other generated article using an algorithm similar to copyscape. I literally compared 500 articles generated from same spintax (single level) and another batch multi-level and the percentages mentioned above are the conclusion I reached.
If you want to do it well, you have to spin multi-level and do it manually. I know people who can generate unreadable content that passes google's automatic filters but he won't tell me how he does it. I only know it is pretty advanced stuff because he told me some stuff and i didn't understood a single thing lol. Personally though I don't want to risk having sites penalized so I prefer to spin manually and multi-level.
Hope this helps
