Which domain parking service provides conversion data?

[Olney]

I recently saw a post on Morgan Linton's blog about ways to pick domains to develop.

He has 4 parking services listed in the post
Trafficz
DomainApps
DomainSponsor
& SmartName

He then writes this

The other day a single click on one of my domains brought in $2,500 for one lucky advertiser, but a mere $5 for me.

I tried to reply asking which parking service supplies this conversion data especially exact sales.
I own a lot of domains that I generally develop for Japan so I haven't tried to use a lot of different parking services.

It might be Epik which I personally thought was a good system (if it wasn't for Google).
I'm writing it in this section instead of the PPC Monitization section because it might be an exclusive system.

I could be wrong, but to me it sounds like Morgan Linton was speculating that his click had resulted in a transaction for the business being advertised ... and also estimating the value of such a client / transaction to the business based on a visit to their website (or a similar website).

Pesonally I doubt that any parking company has much incentive to publish what a follow-through click is worth to a business--or (more importantly) any way of tracking whether a click leading to a website results in a successful paid transaction within that website.

And that's part of what makes the $2500 / $5 comparison dangerous. It's not necessarily true that an ad provider or parked domain is getting the short end of the stick. $2500 for a new client is, indeed, substantial. But how many clicks, statistically speaking, are required to lead to that new client? Is it 1 in 10? 1 in 100? 1 in 1000? That would make the advertising cost upwards of $50 or $500 or $5000 for that single lead.

If I am mistaken, and a parking company does provide such information, I would be legitimately interested to learn that I'm wrong.
