A small business should post proof, a plain explanation of what you sell, and an introduction to who's doing the work, and pin one of each to the top of the profile. The ig-profile skill calls those the pinned three: your best proof, the clearest explanation of the offer and the best introduction to the person. Somebody lands on your profile from one reel and decides in a few seconds whether there's more of that here and whether it's for them.
Past those three, I'd post answers to the questions customers ask you on every call, and short videos built on the formats that are beating their usual numbers in your trade right now. Every post gets one ask, comment a word, save it or follow, not all three. Use your real numbers or none at all, because the second you fudge one, the people who know your trade can tell. And don't pay for a bot to post or comment for you, since Instagram's terms ban using it in automated ways, and that's how accounts get restricted. The free skills in my guide to Claude skills for Instagram content creation score your profile out of 100, write the scripts and the captions, and leave the posting to you.
