Don't use country top level domains for arbi sites as long as you are not targeting specific countries other than us, .us could even be better for us arbi sites?!
I just started trying out arbi and am using free subdomains from afraid.org. They have a huge list with some pretty decent domains, you can only have 5 subdomains if you don't pay for premium membership though.
Anyway! I used the first shortest domain + tld i could find. So the keywords would take up the most space of the url in the ads. Not good! The tld i chose was some korean island i think. What happened was that the text "Ads by goooooooogle" was in French or something on the site. I didn't get alot of ads, and not very targeted either. Probably google put's alot of weight into the tld. I changed to some .us domain instead, and whoop, Ads by goooooooogle in english, more ads, and more targeted ads.
