I've read that some people here offer proof-reading services. That's good to assure content quality, but what worries me is spinning / plagiarism.
This thread / question is about content uniqueness, not about content qulity.
With all due respect to writers around here, I guess some do spin existing content.
Even if done on small scale, this can greatly hurt once G decides your content is unworthy. I'd like to minimize (actually avoid) that risk, while still consuming that kind of service - after all I'd like to scale.
So if you outsource article writing - how do you do that?
How do you make sure your content is UNIQUE?
