Hi, I had applied adsense for my domain called www.example.com , and using adsense in some other websites too. Now I want to drop my primary domain [ ie example.com] ie, I have no plan to renew it.Is it affect my adsense account?
No. You can you change the "master" domain in your Adsense account if you'd like. Just go to the main page after logging in: Click My Account Tab > Find Onsite Advertiser Sign-Up [edit] > Click Edit > You will see the domain listed under "Site Name."
