How do you find an owner? (1.Viewing)

I posted on a particular name recently but let's keep this general.
A few times each month, a .ca domain I want is not being used and I cannot find the owner.

My strategy:
1. Check the landing page for contact info.
2. Use the CIRA request page, you can send a message to the owner.
3. If still nothing, I use archive.org, the Wayback Machine, to see if contact info might have been posted on the website at one time.

That's it. If none of these work I am dead in the water. If I have a client for the name, I know I will never get what would be a fairly easy broker deal and commission.

Does anyone have other strategies?
Much would apply to .com as well. At least with .ca, we get the help from CIRA, I don't think you can get that with a .com.

Check every marketplace

GoDaddy
Sedo
Dan
Afternic
Efty
Sav
etc.


Just in case the domain is listed on one of them and there is a contact.


Believe it or not, I recently did this and got a .com I was after.

Thanks Maple!
I will add your idea to my list, I have not tried that.
I forgot to mention Whois.com or my favorite the whois at Dynadot. Most have very little info, just "Privacy".
Does Verisign do anything to help find a .com?
