What would you consider the best way to help instances grow?

Basically what the title says. I am not typically a content creator, but do try to engage in posts that I can. I'm doing my best to try and help some of the smaller instances for hobbies I am into grow, admittedly I have been slacking a little. For sports I try to post relevant news articles for big stories, for games I try and post questions or something that could get people engaged in conversation. For the most part though it seems like the post get little to no traction. So I am here for suggestions and to see what has been working for other people. Is there something more I could be doing besides making my own video content to get people more engaged?
