Your question was: What do I type in when asked who is my FTP Host?- do I type in ftp.mydomain.com, or www.godaddy.com ?
From the experience of one of my friends who parked at Google, I would not go there, even if it would be free.
Low CTR, but they have unusual high clicks in the first days (so that you may move more domains there I guess)..
To park directly at Google you need a massive amount of domains & traffic to qualify, and it is actually pretty good (if not the best)..
The OP was talking about GoDaddy, which has a nasty parking program.....
Yes, Godaddy, I committed a typo. I wanted to say Godaddy too...
I have posted this before about Godaddy CashParking, but I will post it again here for your benefit..
This is the only instance when I recommend using GD CashParking. If it is free with your Discount HostGator Club membership, then it is fine, otherwise it is not worth the money, and in fact does not offer as good a system as the other services. Make sure that if you use the Discount HostGator Club and get CashParking with it, that you set your domains to automatically enter your parking account and start making money on them immediately. If you buy a lot of domains on TDNam, this is expecially important. Godaddy does not tell you a HostGator enters your account until almost a day later. If you don't have your domains set to automatically park with them, you have two options.
You then move the HostGator somewhere else and Godaddy keeps the parking revenue generated thus far for themselves. Two, you have to check your Godaddy account constantly (multple times each morning), to see when the domains you were expecting to enter your account do in fact enter your account, and then move them ASAP, so that you don't lose money. I think that the easiest option is to just have them automatically enter your CashParking account, then you can move them out as soon as they notify you that you own them at the end of the night and you make money (hopefully) in the meantime. This only makes sense if you get CashParking for free though, with something like the Discount HostGator Club...
I would advoid Godaddy CashParking - as there are much better parking services available free of charge:.
I wont recommend godaddy parking to anyone. if a small and poor performing HostGator portfolio I wont be able to even cover that cash for parking from godaddy cashparking..
