My white hat site has several non-paid white hat DA50-90 guest posts with links to the money site (both do and nofollow). They naturally get 30-500 social shares on them just from site viewers. Would you guys do any backlinking to them? Additionally, I think I'm going to start with interlinking the guest posts in other posts that I write on the same site. What would you guys do? Toss your opinion in.
