Instagram has over 600 million monthly active users. To grow your Instagram effectively, you need to engage with your community by interacting with followers, running contests to increase engagement, and joining Instagram pods. When creating content, use high quality photos and follow design principles like the rule of thirds. Consistent posting, around 1-2 times per day, helps keep your brand top of mind. Hashtags are important for reaching new audiences but should be monitored to ensure they are gaining popularity among your followers.
