What would you do if you have unused domain with pr4? should i build link directory web ? or just parking with an ads?
That depends. What is the domain name? An unused domain with high pr is rather unusual. I'd say that if it was a good domain name you could probably sell it easy enough, if the pr 4 is real and everything. Won't stay a pr 4 long if it remains unused. That is my thought on the subject.
yes i agree with you. it used to be a shortening url web. but now shortening url script is violating the host t.o.s, many host is not allowing to host shortening url to be host. and it stand unused and i need some suggestion, what the best suggestion can i do with pr4 domain :-??
