If you use a domain that has never been used before, I can approve your domain. If your domain has been used by someone else before you, your domain is less likely to get AdSense approval, because the domain that is approved by AdSense once and if that AdSense account is banded, will not be approved by AdSense a second time. Before buying a domain, check the previous history of the website archive.is . And Of course your site must have 25 unique posts. Thank you.
