Reels: what really affects reach

Instagram does not publish the exact recommendation formula, but the general principles have long been known from the platform's official advice and creators' experience: Reels are shown further if real viewers watch them for a long time, rewatch them, save them and send them to friends. Here is what affects that.

The first 1–2 seconds

Viewers decide whether to keep scrolling almost instantly. Strong openings:

• the result right away: a before/after, the finished piece, the final shot;
• a question or problem: "Why does your cake crack?";
• movement in the frame from the first second, with no long intros or logos.

Holding attention

• Keep it short. For a start, 7–20 seconds: it is easier to watch to the end.
• Dynamics. Changing the shot every 2–3 seconds holds attention.
• A loop. If the end flows smoothly into the beginning, the video is rewatched more often.

Text and sound

• Captions or on-screen text — a large share of people watch without sound.
• Trending sounds can help, but only if they fit the content.
• Originality. Instagram favors original content; videos with other platforms' watermarks usually get shown less.

Saves and shares

The most valuable reactions are saves and sends to friends. They are earned by videos that:

• teach something in 15 seconds ("3 ways to…");
• offer a ready solution or a roundup;
• trigger an emotion people want to share.

Add a call to action: "Save it so you don't lose it" — it works.

Consistency and analysis

Post 3–5 Reels a week and look at the stats: average watch time, completion rate, saves. Repeat the formats that work and drop the ones that don't.
