i created my own website and i have got google adsense using my own website but now my website is closed due to some reason "Will google adsense account will be deleted if we dont have a website"?
Adsense account and web sites are entirely different entities. You can put it on free blogs like blogspot.
If you are no longer using it they will disable your account. As a precautionary measure create a free blog at blogger and display ads with your adsense to keep your account going.
Dont think this is right. They wont close your account but ads in your account with go inactive if you dont use them. Once you have an account you have it for life.
