Ok... what on earth is consider Unique Content, is that just referring to writing your own content and not copy others??? and what does it mean by provide quality content...? I just don't see how the google bots can figure out what quality content is, unless taking stats for keyword ratio and the length viewers view a page as representing quality content. ...sorry I'm a noob to this if you didn't already know.
Unique context refers to writing in your own words. Quality can be figured out if people are coming to your website and not staying for long since the context is not good. It's very difficult for bots to figure out content which has been properly spun though.
Unique content is exactly that - Unique not copied somewhere else not spun not refacialised just your spin on whatever you're writing about
