A VERY IMPORTANT point to keep in mind is the fact that you can skip filters that restrict the addition of other URLs than Google. A very notable example is Facebook. If your domain is blocked on facebook but you get a Google redirect, you can quickly put your URL and send traffic to the URL. So this is more than just metrics in ahref. And I'm going to give you a very special tip. If you get a Google Redirect to a link on Adfly, you can literally do more than 50usd a day by skipping many filters and setting your google redirect to adfly url.
