One thing I do not like with the new apps is, it do not want to support PayPal payment.

Just provide your account number and bank SWIFT-BIC and wait till your balance achieve the threshold value. This is normally a three day compared to two weeks PayPal transfer.You can change this in the Account > Payments > Payment Settings )  I have not figured out how to channel my commission payment to my local bank account. The thing I’d like to elaborate is the ads filtering panel. After you have logged-in to the new system (at https://apps.admob.com/ ), find the Account panel on the top-right of the page. Inside the Account panel, click on the Legacy AdMob data menu . Then choose the ...

After completing the registration, login and Add Site/App. Refer to Figure 1. Figure 1 Choose the desired platform and fill in the details (as in Figure 2).
