Basic ER Diagram from Classified site

Databases
1

Hey guys!

My client wants me to build him a classified site that functions more or less the same as this one (but for different products):

Now, its been a while since I have been back-end since I have been specializing in JavaScript in recent times. So I was wondering if you DB pros could tell me if the following database design is sound enough in order to replicate that sites features. Please note that I have left out most of the fields from each table since I am only concerned about relationships at this stage:

I realize that site actually has a very basic Db design, but I just wanted to double check I have the right approach!

many thanks :cool:(:;):eek:

I have also updated the diagram to include tagging functionality:

I am not really all that familiar with tagging, but I did some research and that setup was recommended:
