Like the title says I'm wanting to know through your experience how does google interpret articles, or more specifically, heavily spun articles. I'm asking this question because it pertains to my backlinking campaign. I have been building links through teir 1 and tier 2 web 2.0's for the past couple of weeks. I've always spun my tier 2's to about 70% unique and hand wrote my tier 1's. The more I think about it the more I question if it's necessary to write "coherent" tier 1 articles. I mean if an article is 70% it seems to always pass copyscape. I CANNOT imagine google, even being one of the most financially capable corporations to have such computing resources available that can distinguish heavily spun "unique" content from it's source. Does anybody else do it this way, what are the results that you have been getting? Can I get away with just spinning the crap out of my web 2.0's and keeping the content excellent on my $$ site? How could google possibly monitor this? Thanks guys!
