Best place is to park it on your server with a CPA offer on it and even a tiny bit of seo/backlink work done. I've been less than impressed with some parking stats I've seen.
Most parking companies do not pay you. You earn far more making a small website, if you have chosen your domain properly.
Haven't found the best parking company out there yet as I haven't tested them out yet except for Sedo. Only managed to make 1-2 cents per click there I would have to agree, the best way would be to create a minisite, then you'll get more
Godaddy pays 80 % of revenue. Some sites make upwards of $5 a month on expired domains I bought. Most sites average $1 a month. Better with a small site, like previous posters suggested.
Namedrive cpc rates decreased so much that it's better leave the page blank with a contact form rather than park it there but anyway... I agree with most people here. It's better to create your own minisite but let's not forget that many people are lazy or have too many domains to be able to create minisites for all of them, or maybe they want to develop 10-20 sites but in the process of site's creation they have to stack the sites in a parking program The best by far so far (hoping it will not change when they get more people) is parkingpanel.com. Their rates per click are mind blowing and believe me when i say that i used most of the parking services already, i don't know for how long they will be like this so i can't guarantee anything after 6 months or more but for now they are the best I parked about 320 sites there already and feeding them with more sites as soon as i get them My sample portfolio get me in in 2 days but i heard that there guys waiting for 2 weeks or more. They ask for a referral at the signup form "Note: If you have a referral you are most likely to be approved quicker. We do not accept all applicants, so please be thorough in explaining your situation to increase your chances for approval on our system" So if anyone needs help signing up with them PM to refer you Don't forget that if you don't test most of the parking services you will never know what works best for your domains
