In the past we have used fixed HTML pages and found that relevant urls to the prouct helped us acheive good free listing. When i was experimenting with other eccomerce active server pages we could change the url from
http://www.toplants.co.uk/catalog/in...dex&cPath=3_12 to something more logical that we think helped are listings example would be

http://www.toplants.co.uk/catalog/gas-barbecue.asp

Can this be acheived in Zencart?

Thanks
