I don't know if I am that popular, but I do not what is working for me so far.
Just create good content and interact with the community. Read, comment relevant comments on other posts and upvote if you feel they are upvote worthy. For me, if I am taking the time to comment, I usually upvote. The rest will come with time, but I suggest you read the Steemit whitepaper, it will help too.
