Hello,

I have a client who has a large ecommerce website. Some category names have been created with comma's in - which has meant that their software has automatically generated URL's with comma's in for every page that comes beneath the category in the site hierarchy.

eg. 1 : http://shop.deliaonline.com/store/music,-dvd-and-games/dvds-and-blu_rays/

eg. 2 : http://shop.deliaonline.com/store/music,-dvd-and-games/dvds-and-blu_rays/action-and-adventure/

etc...

I know that URL's with comma's in look a bit ugly! But is there 'any' SEO reason why URL's with comma's in are any less effective?

Kind Regs,

RB
