question is, how much strength does Amazon.com domain can give to its sub pages like those subpages: http://astore.amazon.com/bla.bla-20 and could this pages get rank and strength and index in Google after a while without promoting them?
since amazon is a high of site, its subsites will benefit greatly from it so even with out promoting it will rank high
Why not just look at some other astores that have been around for awhile and see how they are doing in search results based on the keywords provided on-page.
