If you bought the domain name, the typical procedure is to unlock the domain name, then either push it to your account at the same registrar (such as https://www.domainsherpa.com/how-to-push-a-domain-name-at-godaddy-com/) or send you the authorization code so you can transfer the domain name to a different registrar (https://www.domainsherpa.com/how-to-transfer-a-domain-name-to-another-registrar/).
SEO is not as easy as it used to be. The market is very saturated now, content is now incredibly easy to generate and publish. Everyone and his dog (or gran!) can make a wordpress website. The main ranking factor for Google is still backlinks and will be for the foreseeable future. Your content might be better than your competitors but if they have more links they'll simply always outrank you and receive more traffic. Fair or not, its a fact. This method can see you get the strong backlink profile you need to rank #1. Please note a PBN is considered black hat so please diversify your backlink profile and do your research first.
