Hello All, i have a plan to make site directory. i want to put adsense on it. is it allowed? second question: my domain is www.mydomain.org. i can still put adsense on .org domain, right? there is no adsense TOS related with domain name (.com , .net, .org, .info, etc....), right? (sorry because this is my first time make site with .org domain). thanks for all help.
No go ahead and do it. There is no rule against placing AdSense on particular TLD's i.e. .org. Just read through the AdSense rules so that you know what you can and can't do, so you don't end up getting banned for any other reason.
if you receive nice traffic on directory then its best for adsense, regarding .org domain i prefer .com domains
