I have bought a few domain names recently, I parked them and listing them for sale at a domain marketplace. My purpose is to sell them, not for making money from parking. I see there are very few visitors to those parked sites, I am wondering does parking domain produce any traffics? Should I build a simple site myself (or used WP) or just park them? If I build a simple site I could edit the meta detals for SEO purpose, but I can not do anything with is when I park them.
So which is better for make traffic grow, to built a site or park it?
