Direct Answer
Most service businesses get the best ROI posting 3–5 times per week on Instagram, including a mix of feed posts, Reels, and Stories. Posting fewer than 2x per week loses algorithmic visibility; posting daily without quality usually drops engagement rate.
Short version
“Post on Instagram three to five times per week. Mix feed posts, Reels, and Stories.”
Reels reach 2–4x further than static posts in 2026 — make at least 1 of the weekly posts a Reel.
Engage on every comment within 60 minutes — Instagram's ranking model heavily weights early reply activity.
