What's the clickthrough and earnings per click? That's what you really need to look at to see what the problem might be. You should generally expect about a penny per unique, and so you're currently making about half of that. However, adult EPC is generally pretty low, like 3-7 cents per click on most parking sites.
I will say that I've had a pretty good experience at Fabulous.com parking adult names there. My AdultPortal.com for instance has 578 uniques since the beginning of October...not too much of course, but it's EPC is $.1188 and its clickthrough is 29.2%, so it's earning over 3 times the penny per visitor guideline. I've had some adult names have over 50% clickthrough.
If I were you, I would go through the following:
1. What was on the domain before? Archive.org it and see if it might be foreign-language or if it's a particular niche site such that visitors won't be clicking away unless it's specific to that niche.
2. Sometimes more important, check where the visitors are coming from. You say it's all expired traffic, but they're still either typing the domain in or are coming from other sites. One of the reasons why I love Fabulous is that you can view the Host stats on domains you have parked unlike places like Sedo, and they list any incoming URLs, so you can see exactly where the traffic's coming from, if anywhere. If there's very little referral traffic, you can deduce that it's being typed-in, though you should probably check that on OVT. If it gets 10,000 a day, it should have OVT w/ ext results if even a meager fraction of that is type-in traffic.
2a. If there are mostly referrals, see what's on those referrals and what context the link to your site is used in. Figure this: when people click that link, they're going to have an expectation of what's on your site. If they get something completely different, they're not going to be likely to click on the links.
2b. If the traffic is type-in, then it's going to either be due to the previous website that was on it, or the domain itself being strong. If you didn't find much to warrant the traffic on Archive.org, then it's probably the domain itself. If it seems like a weird domain to you and you're not sure of the keywords making it up, then check Google, Dictionary.com, Acronym Finder, etc, and find out what your domain means. If it's pretty obvious what the keywords of the domain is, then try to tailor your parking to fit the keywords of the domain. Ironically, that's what everyone generally does anyways, and lack of clickthrough is usually a case where something completely different was on the previous website, but sometimes the domain is reflecting something specific and the parking you put on it may be too generic.
In total, I can't really speak for what most parking programs have to offer except to say that the ones I've used the most have been Sedo, Afternic (usually to sell domains), and Fabulous, and Fabulous crushes both Sedo and Afternic and has impressed me to the point of being skeptical of trying something else. I have a domain, Host.sh, that I had gotten expired after it had been a free adult hosting site (as in it had a lot of
www.host.sh/*blah* subsites that had adult content). Initially when I got it, I did not know about how good Fabulous was, and was still parking everything at Sedo. The name at the time was averaging over 1,000 uniques/day and about $10.00 a day (the penny per unique I generally expect). Over time, the domain has gone way down in visitors and now averages only about 60 uniques a day now, but for the limited time I had it on Fabulous with adult parking, the rate of money I was making was about 5-6 times what it was making on Sedo! There was over $1,000 I could have made from the name if I knew the best place to park it!
So yea, if I were you, I would try to get approved for Fabulous's premium 5.0 parking program. Usually they need a portfolio of many names, but if you have a name getting that much traffic, they'll probably approve you. If you want, you can email
[email protected] after submitting your portfolio to them and tell them that user Crooky0 (me) referred you to them, and that might help you get approved too. I've made over $10k there and thus have made THEM a bunch of money too, so hopefully they don't take that lightly!
