Well let me give you some quick info.
over 1 million products = 1 million+ pages = 5 million+ keywords.
Keywords are generated from relevant content in the body of the product page.
For example:
A product page on our site for buster brown socks has a title of this:
Buster Brown 6-Pack Infant Boys Crew Sock
Which could be changed to this:
Buster Brown 6-Pack baby Boys Crew Sock
This would change Infant to baby in the title, description, keywords and body, which would eliminate our duplicate content problem.
I agree that human being paraphrasing is the best route, but not in a case like ours with so many pages and products. Not to mention we get a new set of product catalogs every week, so it has to be part of the script or it will be impossible for human paraphrasing.
