I have 4 domains and I want to create an account in which i can generate traffic and some cents per week. Suggestions and recommendations?

Thanks,

How much traffic do these domains generate? You won't get any additional traffic by parking them at Sedo or similar. As a rule of thumb you can expect $2-5 ad revenue per thousand visitors to your site. (I'm sure someone will share a different opinion). :) Your best bet may be to develop the sites with content so they generate traffic.
Have I understood your question correctly?

Thanks Techno, I appreciate your response. Good answer.

sedo would be your best option as they dont have any minimum hits requirement

If you want to park your domains and earn revenue from the clicks then Sedo, Afternic, Goldkey, NameDrive all have no minimum requirements.

If you want your domains to generate traffic, you will need to get a webhosting account and develop them by putting content on your domains. You don't need many pages, 1-5 is sufficient. You should then signup for a Google Adsense account and put their ads on your pages. Then submit your domains to the search engines, Google, Yahoo!, MSN. You should also submit to as many directories as you can find.

Can domain parking become an enterprise? some ideas?

hq12,

What do you mean with that? I did not understand what you mean with "domain parking become an enterprise"

Let me rephrase the question. By spending time and money buying domains and parking them. Can these actions become a sustainable small company?

lots of companies became multi-million empires from parking.

so sure you can

I wish I was one of them :(

I see, well. I just started with 4 domains. If i make some bucks i ll let you know.

You won't make much unless the domains get type-in traffic. Most new registrations have no type-in traffic. They'll need to be developed and had adsense on them.

What are the requirements to participate in adsense for domains?

i know people who are earning $xxx and even $xxxx from parking

i personaly dont, more like $xx per month at Sedo, but its better than
nothing for doing nothing

Thank you all for the observations.

I've spent XX,XXX and earn XXX/month from parking :) Is it a good return? Nope. I'd rather be sipping umbrella drinks on the beach across the road :(
