Google Dropping Affiliate Pages in The Rankings

Google's been busy! If you've seen the affiliate pages appear, disappear and bounce around in the rankings you could be suffering from a bad case of "duplicate content" penalty. 

This algorithm has been beefed up and if you don't see your site, go to the end of the results where you see "repeat your search with omitted results included". Your URL has probably been judges as duplicate and relegated to the supplemental index.

Duplicate content is becoming a big issue with so many affiliate sites or people stealing content outright from good sites. So Google put a stop to that kind of non-sense.
