It seems like you’re already doing a good job with regular posting and community interaction. However, it might be worth trying a few additional strategies.
Diversify your content: Experiment with different content types such as Reels, IGTV videos, and Stories. Instagram’s algorithm tends to favor accounts that make use of all its features.
Influencer partnerships: Collaborate with influencers or other brands in your niche. This can help to expand your reach and bring in followers who are already interested in your content.
Consider aesthetic consistency: A visually cohesive feed can help attract and retain followers.
Lastly, if managing all of this seems too overwhelming, there are agencies like Ascendviral that specialize in helping brands grow their Instagram presence organically. They could provide guidance and help ease your workload. Good luck!
