This is in addition to the answers that I already see here. Plan for curating unique or fresh content. Think what exactly you are doing; there must be something unique about it, in the way you approach your work or execute your skills. Plan your posts around it to give users something they do not get so often!
If you are not doing something different; try to structure your posts differently! Weave a story, and use some engagement strategy. Audience is looking for value, yes, but anything new or fresh is a huge bonus.
