As social media rapidly progresses and becomes an essential marketing tool, it becomes important to understand their algorithm. Instagram looks at the engagement on each post instead of just the number of followers. With more followers and less engagement, your brand is not sending a positive message to the algorithm.
Instagram is currently testing a new feature that allows the brands to delete their followers even if it is a public profile. This allows brands to delete inactive users, bots or even friends and family who just followed the brand to be supportive. The number of followers does not matter as much as the number of active and engaged followers.
