The new AdMob interface was launched last week (I was invited on early May 2014). The transition was smooth however from my experience I lost all my account balance in the old interface.
One thing I do not like with the new apps is, it do not want to support PayPal payment. (Update – later I found out that the new AdMob facility provide direct wired-transfer to you favorite local banks. 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 Review and Set ad filters (refer to screenshot below).
You can block competitors’ URL.
Or block ads by category. However this is not a good approach, as you block one general categories, all the sub-categories will also be blocked.
Hopefully the will have ads filtering based on keyword very soon.
