Promote your posts by burning STEM to @null
Send STEM tokens to null with a STEM post in the memo. This will push your post above all others as a promoted post. It takes very little STEM to do this and be placed at the top as there is little competition for this feature right now.
By using STEM for promotion you reduce the STEM token supply increasing the potential value of the token.
