First step is I create a gmail account and profile this account. This gmail is then used to create accounts on high domain authority accounts. Mostly they are DoFollow and some NoFollow.
Sites like: GoDaddy Sites DA 93 PA 66, Over Blog DA 93 PA 82, Creative Commons DA 95 PA 84, WordPress DA 93 PA 88, Strikingly DA 90 PA 67 and so on. There is a mixture of Blogs, Profiles and Redirects.
Over 100 are manually created and these then get indexed. Then I create niche relevant content and then backlink all these links.
The result of this is a mixture of blogs, profiles and branded accounts linking back to your website with a mix of mostly DoFollow and some NoFollow links.
The relevancy is passed through these high authority links which can result in increased ratings but more importantly should result in increased rankings in organic search.
I am not manipulating the DR just to show a high DR that has no power.
