It took me some time to understand why Google didn’t allow me to create another AdSense account for my second blog. Their policy doesn’t allow you to do that, instead you can get a separate Google Account for your second blog, but with your AdSense account integrated in the old account.
Anyway, I figured out how to transfer your AdSense account to Another Google Account. Here are the steps you have to follow.
Step 1. Create a New Google Account on using different name, family name, mobile phone gmail.com. For example: email@example.com
Step 2. Login to adsense.google.com with your new account firstname.lastname@example.org
Step 3. Click On Account Settings from upper-right on your screen. See the screenshot bellow.
Step 4. From the left list select Access and authorization, then under it select User management.
Now in the window under User management, you have to invite your old account: email@example.com and click invite.
Step 5. You will receive an email on your firstname.lastname@example.org that you have been invited, you will have to click the link in the email to Accept it.
Step 6. After accepting your invitation, you will have to login one more time to your email@example.com AdSense. Again repeat step 3 and 4, but this time you will not have to invite your old account, but you will have to give it the administration role from the same window.
That’s all! Now you have successfully transferred your Google AdSense accoutn to another Google Account.
