Welcome to the Q&A Forum

You could create a structure like this: http://site.com/iphone (generic content about the iphone) http://site.com/iphone/4s-sprint (specific information about this version) http://site.com/iphone/4s-verizon (specific information about this version) http://site.com/iphone/4s-at-t (specific information about this version) This is just one approach but it depends on your site structure. One constant remains, however... create unique & compelling content
