There is a process for submitting a new URL, but what you can't do is change the URL in the application you already submitted. When you try to apply with a new or different blog in your Blogger account, the application is automatically submitted with the same URL you submitted with your first application. The same is true if you try to apply for Adsense using a YouTube Channel - if you applied for Adsense with a blog or website (and were rejected) before you applied from YouTube, the URL from your old application may automatically be submitted to Adsense, instead of your channel.
In either instance what you'll need to do is first create a new Google Account and a new Gmail account for that new Google Account. WAIT! No, you don't have to delete your current Google/gmail accounts and no, you don't have to create a new Blogger or YouTube account to do this.
The first step is to log out of your current Google Account. Then create your new Google and Gmail accounts. Once created and verified, log out of that new account you just created.
The next step is to login to your current (or old) Google Account, and then go to your Blogger Account or YouTube account/channel. Now you're ready to submit a new application to Adsense using a different URL than you previously used. Yes, it's a little confusing but once you know the steps, it isn't that bad.
Go to your YouTube Channel that you want to submit and find the Monetization tab. On your monetization tab you'll see a list of guidelines and other information you should know. Click the little down arrows next to each one to expand those sections and please, DO read the information.
Notice the section that says "How will I be paid" - there's a link there to associate an Adsense account with your YouTube channel. Click that after you finished reading this information and it takes you to a page with further instructions. READ those, then click next. That should bring to a place like this one:
PLEASE NOTE: You must be 18 to apply for Adsense, and that the information you fill out on your application (such as your REAL name) must be correct - double check your entries for spelling errors because you won't be able to fix them later on.
What you want to do here is select "Use a different or new Google Account". Once you select that, it will ask you for the information for your new Google Account. Fill that in, and complete your application using your current YouTube Channel.
Note that if you have multiple channels that use different emails/different Google Accounts, you can also use these instructions to associate those channels with your approved Adsense Account.
The steps to reapply through your Blogger account with a new Google account are the same. Make sure you are logged in to your current Google Account and sign into your Blogger account. Select the blog you want to submit and go to the Earnings tab.
You should see something like this page:
Click the "Sign up for Adsense" button and you'll get the steps to sign up for Adsense.
Make sure you understand that you cannot apply if you are under 18. This page will show your current Google Account/email address (the one associated with your Blogger account). When trying to submit a new or different blog than one you tried before, you can't resubmit using your current Google account. Choose the orange button that says "Use a different or new Google Account" and give the information for the new Google Account you created, then complete the application for Adsense.
For both YouTube and Blogger, you'll have 2 Google Accounts - one associated with your Blogger or YouTube account, and one associated with your Adsense account. These steps essentially link your accounts, so make sure you do keep track of the login information for both of your Google Accounts.
