Helllo, I am very confuse from this situation please help me! From last year my adsense was working on my old website which was hosted at geocities.com (Free WebHosting) but geocities free webhosting is closing from 26 Oct 2009, so I bought new dot com domain one month ago. 1. I move all content, pages with same name from old website to new website 2. I did not close my old website but I give a new website link on each page on my old website (which were getting lot of visitors) becasue I don't want to lose my visitors from old website! which is giving me 50% traffic on my new website. Now questions are that: Is this risk for adsense account that Apprx 50% traffic comming from a One website? and Second my domain age is only one Month not 6 months...
Don't worry about where the traffic is coming from, but you should make sure that your adsense ads are set up for your new domain and not your old domain.
Adsense does not have such limitations at all. You can put adsense in your websites no matter how old or new they are as long as they follow the adsense tos. So no need to worry about the domain age.
Another thing that I would try since you said you migrated all pages from the old site is to setup a redirect. At least this way, you shouldn't lose any of your traffic since all pages of the old site will redirect to their respective counterpart on your new website.
