anyway to find out how many typins a domain gets...
 

that isnt yours?

buy it maybe? :)

server stats.
thats about it.

you can estimate it, but no way to know for sure...

but how woj?

Count typins as a % of overture search terms on domains you own. Do this for a bunch of domains to get your mean, then apply accordingly.

I think one of the problems with counting type ins at the server level is if a user's referring URL is blank, on purpose or otherwise, it looks like a type in to your server.
