Lets say I have a site that sells fruit. its www.fruit.com I allow fruit sellers a place on my site to sell their fruit they get their own url www.fruit.com/sellerjohn John uses that url and has been for several years. What if I wanted to help John sell more fruit and altered his URL so that it read www.fruit.com/bananasforsale Would this page be then better indexed? and accessed by those looking for "bananas for sale" I was thinking that if there are 100 fruits and types of fruits and I rename all the URLS and 301 redirect them to the personal pages will this work? In other words instead of /sellerjohn all the inner pages would be the KW of what that person is selling. Would this be frowned upon?
