On average, given one 500 word article, how many spinned articles could writers here create? That's articles that are sufficently unique from each other to pass Copyscape, Google etc. I understand that the subject of the article may make a difference, but I'm looking for a rough estimate. btw. this is not a request for re-writing services, I'm just wondering how much effort can be put into article spinning to produce genuinely unique (which is not the same as original ) articles. Or is most re-writing automated now because writers won't touch this kind of job with a ten-foot bargepole?
For general/mainstream topics, I'd say 5 paraphrased yet quality articles at max, but for IT/science/finance-related subjects, 2-3 paraphrased articles would be the most probable output given the circumstances that each article should pass Copyscape and other unintentional/intentional copy-paste checkers.
You could do a lot, because (in theory) a 30% differential will pass Google's dupe filters. Of course, this is in theory only. Ideally, you want a 50% differential. The real question is structure. Does google look at words as they appear or do they analyze the document as a whole. If they do it as it appears, simply reordering the content will do the trick. If not, there needs to be significant changes.
I'll only do it 3, maybe 4, times max. I aim for 85% uniqueness in each rewrite, so that means coming up with different phrases, rewording info, etc.
Of course it's going to depend on the amount of information that's in the article, but I'd say up to 5 or 6.
Like everyone above has said, it depends on the amount of information contained in the article. In general, I can create 2-3 paraphrased articles out of a 500 words article, while keeping the copyscape testing in mind.
