As @TechnoBear told that, social media is a place to be social not for dropping links.
I suggest you three things that can help you increase your chances of backlinking.
-
Create content that can add value to your blog industry. Not just copy and paste.
-
Include case studies and new statistics that encourage other’s to refer you.
-
Create infographics and share them on social media. especially on Twitter
-
Guest blogging
