I am passing parameters ("product category" & "product name") in a url to a buy page.
Which is preferable in regards to the norm/standard for passed parameters in Web URLs?
https://example.com/purchase/?productCat=personalSign&product=secureEmail
alternately:
https://example.com/purchase/?pcat=ps&p=se
i.e. Is giving full visibility of the parameters necessary? Or are shortcode random character strings acceptable in current Web design?
I would be very interested to hear advice on URL and parameter structure, with user/research data supporting any theories.
