How can I increase my Instagram engagement rate?

Hello, I wanted to ask you guys if you know of any way to organically increase tge engagement rate on my instagram acc. Lately I've seen a decline in my engagement, and I can't figure out fir the life of mine why this is. At tge moment I have 9953 followers, but my posts at this point barely make it to 1.5k likes per post. Last year fir example I only had half of my following, but a lot of times got 10k likes and more on posts. Does anyone here know why this could be? Or how I could get my engagement up again? Thank you all in advance!
