Instagram Trust Score
Not too many people know about how Instagram weighs certain accounts. They actually implement a trust score to reward authentic action on the platform. Actions like posting consistently (#1), commenting (not spamming), liking posts in your feed, replying to comments- all boost the trust score. Things like the same hashtags every post, shadow banned HT's, follow/unfollow, spam comments, spam likes- reduce your score. A high score gets you two things:
1. Increased organic reach for your posts
2. Ability to perform more actions without getting banned/blocked in order to gain awareness on the platform.
Be organic and get rewarded organically!
