Hi, I have been actively doing guest blogging for last few weeks . But the page authority , moz Rank and moz Trust of my guest posts appear 0 as those posts have their own pages on blogs  with snippets of posts on home page.  I wanted to ask if i should backlink to my guest posts to increase the authority, mR and mT of pages. Those posts are already appearing as backlinks in webmaster tools but if i backlink to my posts to increase mR and mT, then will it also increase the juice passed by backlinks in those posts to landing pages on my site ? Thanks,
