Use same AdSense account for a million websites: Reassurance

It is very common for new AdSense publisher to wonder if they can use the same AdSense account for more than one website as long as the page that contains AdSense products (ad units, link units, search box, referral links or buttons) (click BACK button to get back to this page) complies with Google AdSense Program Policies and Google AdSense^TM Standard Terms and Conditions.

Some of them will ask if they should use different account for different websites (very common question). The answer is a definite NO as one is only allowed to have one AdSense account. If the reason why you want different account for different website so that you know which website is performing better, you don't need different account to do that. To track performance for different websites, create AdSense URL channel (click BACK button to get back to this page). If you are not familiar with URL, refer to What is URL and how to get it.

How to make sure that AdSense products in different websites will earn income for your

Some will still feel uncomfortable even after telling them they can use the same account for a million websites (as long as conditions are fulfilled. No need to check with AdSense support (click BACK button to get back to this page) because very likely they will not check for you but push the responsibility of complying back to you). If you need reassurance, just make sure that the scripts have your publisher's ID. A Google AdSense publisher's ID will look something like this:

pub-9408074345704638

You can get your publisher's ID by clicking on the "Accounts" tab after signing into your AdSense account (highlighted by a red arrow pointing at it in the screenshot below:

You only need to confirm the part I gave above, but actually there are 3 IDs involved:

AdSense for Content: ca-pub-9408071234704638
AdSense for Search: partner-pub-9408071234704638
Referrals: ca-ref-pub-9408071234704638

To me, only the part pub-9408071234704638 is important.

Just to make sure you know where to look for the ID when you get the script from your AdSense account, I will put 3 examples of the scripts and highlight the important part in red below:

Now some of you will add Google AdSense ad units direct from Google Blogger for those who are bloggers. Now I would advice against that as generating the script direct from your AdSense account (click BACK button to get back to this page) gives you more flexibility, and the only time I do that is when I want to add ad units between posts. In this case, you will not be able to see the script directly, but you may have to view Page Source (if you don't understand this, ask by commenting and I will give you the answer) and search for the script in the Page Source.

OK End of long post. Hope you sleep well tonight.
