How to create quality DoFollows Backlinks to my blog?
 

I have tried using fiverr and other SEO but now I wish to do it manually in order to learn.
Can anyone please help me to understand how high PR backlinks are made specially DoFollows.

Google are aware of websites that are targeting only do follow links and you intend to manipulate the rankings.

Gogle aware that are tergets only dofollow links.

Google target only the dofollow links therefore every link building should be done on the dofollow links
