Just wondering and trying to figure this out. If only a few words in the content are different is it noted as duplicate or not? If I have several keywords I want to optmise for the best thing I learned is to make a page for it and write the content do the on page optimalisation as well as the off page. But what if my keywords are close to each other and the content is in a standard form like a listing of features. fi if I target for green basic t-shirts as well as blue and make a page about both with the listing of weight, price, shipping and stuff like that which is all the same except the color will it be flaged as duplicate or is the small differnce enough to be passed on as unique?
given that both your pages are on the part of the same domain name, they might not be penalized. but its a better idea to try and diffrentiate some more between the pages, try changing to the sunonyms of some words (not the keywords) this will make alot of changes in the pages while keeping the same meaning. Plus these changes will not matter on your key word opptimization
