Grow organically & retain

How do I grow an Instagram account for my business, from zero and for free?

Post original Reels that people send to a friend, every week, and test new ideas with trial reels: that is how a new account grows without paying. Instagram says its Reels ranking predicts whether someone will reshare a reel, watch it to the end, like it and open its audio page, and Adam Mosseri has named watch time, likes per reach and sends per reach as the signals that carry most weight, with sends mattering more for reaching people who don't follow you. Instagram shows fewer reels that are watermarked, low resolution, mostly text or already posted on Instagram, so film your own vertical video rather than reposting. Trial reels go first to people who don't follow you, so a small account can test a hook without its followers seeing a flop. Stay in one niche, open every reel with the problem it solves, and reply to every comment and DM. Bought followers never watch or share, which is what Instagram ranks on. The rule: make the reel your customer would forward to a friend.
