Seeking effective social media engagement tactics for nonprofits on tight budgets

[MasonD]

I manage social media for a mid-sized nonprofit focused on environmental education, and while we have a decent follower count, our actual engagement rates on Instagram and LinkedIn have been stagnant for months. We post consistently but it feels like we're just broadcasting into the void. I want to shift our strategy to foster genuine community and conversation, not just likes. For social media managers, especially in the nonprofit or B2B space, what engagement strategies have moved the needle beyond standard Q&As or polls? How do you effectively leverage user-generated content or advocate partnerships when you have a modest budget, and what specific tactics have you used to encourage meaningful comments and shares that actually expand your reach to new, relevant audiences?
