What is the best way to structure website URLs ?

[SierraPCB]

Hi,

can anyone help me to understand if having category folder in URL  matters or not?  how to google treat a URL?  for example, I have the  URL www.protoexpress.com/pcb/certification but not sure google will treat it a whole or in separate parts?  if in separate parts, is it safe to use pcb/pcb-certification?  or it will be considered as keyword stuffing?

Thank you in anticipation,

If you're trying to rank the page for the term "PCB Certification" it certainly makes sense to have that as the page name, it also makes sense for it to be in a folder called PCB with the other PCB related pages. You certainly wouldn't be penalised for that approach.

Google will separate out the various parts of the path, so you don't need to worry about it treating it as a single keyword.
