Just upvote your post, WHILE you're posting it, NOT AFTER.
Algorithms in social media sites take several variables to that rank the trends. Those include not only the actual number of likes/upvotes/comments, but also "the likes/upvotes/comments per minute/second since the post"
Of course this won't have a HUGE impact on your upvotes and follows, but it'll probably provide a slight improvement.
