Hello everyone,
I'm a bit new at this and I have a quick question.
Can I use the Adsense account for several sites I own or just for the site that it was approved?

thank you in advance.

You can use it for any site that follows the AdSense policies.

you can use your adsense code for unlimited domain names. but the thing is, people can track your websites if you keep on using the same adsense code. solution? better register another account using your brother/sister name; and give them some commissions of course

or just form your own LLC co ....cheap, and offers protection of your personal assets

If you really want to get into the BH game then anonymity and diversifying your assets becomes a second nature. While most of the BW tactics are not against the law (excluding Spam and Fraud (selling something that does not meet the description) it is the most of the times against the TOS of the providers. So for instance is the use of site mass builders for the creation of adsense sites that do not bring "good content" to the user.

Thus if you use this kind of software to earn your money your adsense account will be banned at some time ... Thus it is in your best interest to have several accounts (which is also against their TOS) under different names (using different IPs ..etc) to mediate the risk of waking up without having any income (somehow this always happens over night ...)

So to make sure this will not happen to you you will create different IDs by creating LLC's Cooperation or DbA (maybe even in in different countries) and get several accounts with each of the money sources you work with .... Po boxes, Paypal accounts, etc ...
It all becomes a second nature .... Just make sure to include all your income of the different entities in your IRS ... you don't want to mess with the feds
Have fun...
