Instagram uses different ranking systems for Feed, Stories, Reels, and Explore. It evaluates three core signals: user behavior, content information, and relationship strength. You improve reach by posting consistently, using keywords, creating clear themed content, and encouraging engagement. SocialPostAI helps you automate this entire process through ready to use captions, scroll stopping designs, and monthly content planning.
