Thanks for the advice guys. What if I didn't plan to build a website for the domain and instead, I just want to sell the domain. Do I still need a simple website (or web page) for the domain?
Maybe I'm missing something, but I don't see how the question applies. I don't promote a parked domain. I don't think anybody does. Rather, it promotes itself by appearing in a parking website.
That's a good point HostColor, thanks. Does it mean that I will have to create a single page to display the ads and host it on my own (shared) server?
