Hello,

If I have multiple sub-category of the same name ? does that affect SEO for example I have the following category structure?

domain/bmw/series5/2006.html

domain/bmw/series5/2007.html .. etc

domain/bmw/series3/2007.html

domain/bmw/series3/2006.html  ..etc

domain/Acura/cl/2006.html

domain/Acura/cl/2007.html .. etc

I do use canonical url because I may have the same product in multiple categories but my question does google penalize me because I have the same (year) url key for multiple categories  even though I use canonical url ?

do I have any advantage in masking them filters vs sub-category from SEO point of view ? specially my goal is to have different meta title and meta description for each sub category ?
