2.1Instagram (Reels, stories, carousels)
The essentials in 30 seconds
- Three machines: Reels = conquer (reach), carousels = retain (saves), stories = bond (closeness) — all three, not one.
- Algo signals: engagement (shares, saves, comments) and retention (time spent) — the hook decides.
- Reflex: vertical 9:16, 1-second hook, subtitles (80% muted), 3-4 Reels/week + daily stories.
Threaded mini-case — Nour launches her shop on Instagram
Nour runs a small deco shop in Algiers and opens her pro Instagram: she posts a pretty recycled horizontal photo, no subtitles or call, then waits. Zero reach. Re-reading the section, she rebuilds: vertical 7-30s Reel with 1-second hook and trending audio, 5-8-slide carousel with a promise, daily stories with a poll. She replies fast to comments. This case returns in the lesson, the diagram, the script and the 48h challenge — and continues in 2.2, 2.3, 2.4 and 2.5.

1. Reels: the reach machine
Vertical 9:16, 7-30s, 1-second hook, subtitles (80% watched muted), trending audio (↗ arrow), loop (end = start: re-watches). Publish 3-4/week, reply to comments fast (early signal). The average Reel dies at 3 seconds: nail the first second.
2. Carousels: the saves machine
5-8 slides, promise cover, 1 idea/slide, closing call ("save this"). Saves + reading time push: a value carousel outperforms 3 showcase posts. Second chance: Instagram reshows the carousel (slide 2 as cover).
3. Stories: the closeness machine
Daily, raw (behind the scenes, polls, links), interaction stickers (poll, question, quiz), organized highlights. Stories = retain followers; Reels = conquer: both, not one.

Nour runs each format by its role.
Mon: behind-the-scenes Reel (trending audio) | Wed: 5-tip carousel
Fri: before/after Reel | Daily stories: poll + shop link
→ ×3 reach in 60 days, ×5 saves on carouselsTakeaway: each format does its job.
Lesson: systematic subtitles (80% muted).
Section vocabulary
- Visual-first social network (photo/video), major for brands and creators.
Simple example: Nour shows her shop there in regular vertical visuals.
What it is not: recycling a horizontal video there with no adaptation.
Reflex: each post: vertical, visible hook, clear value.
- Reels
- Instagram's vertical short videos; the most pushed format for reach.
Simple example: Nour posts 3-4 Reels/week with 1-second hook and loop.
What it is not: a horizontal Reel with no subtitles or sound.
Reflex: 1 second of promise + movement + on-screen text.
- Story (Instagram)
- Ephemeral content (24h) for closeness, behind the scenes and interaction.
Simple example: Nour polls daily and organises her highlights.
What it is not: never posting stories for lack of time.
Reflex: one story a day: behind the scenes, poll or link.
- Carousel (Instagram)
- Multi-image swipeable post; ideal for educational content.
Simple example: Nour makes 5-8 slides with 1 idea per slide and a final call.
What it is not: 10 confusing slides with no promise or call.
Reflex: promise cover + 1 idea/slide + save this.
- Hashtag
- A #-prefixed keyword helping discoverability (relevant, not too generic).
Simple example: Nour adds 3-5 niche hashtags tied to the post.
What it is not: stacking unrelated generic hashtags.
Reflex: useful complement, never the core of reach.
In practice — Hands-on — Master Instagram
- Use formats by role: Reels (reach, new audiences), stories (closeness, interaction), carousels (education, engagement).
- Feed the signals valued by the algorithm: engagement (shares, saves, comments) and retention (time spent).
- Nail the visual hook (the 1st image/second decides the scroll) and bring value.
- Add relevant hashtags (not too generic), publish regularly and encourage interaction.
Ready-to-say script — launch the week's Reel (30 s)
"This week I show the shop window's before/after in 15 seconds: vertical, first second with the result, subtitles, trending sound, and at the end I say: save this post for your deco ideas."
To say before shooting, to frame hook, subtitles and call.

Frequently asked questions
Are hashtags still important on Instagram?
They keep a usefulness, but their importance has evolved and declined. Hashtags serve discoverability and categorization: they help Instagram understand your topic and suggest it to interested people. But they are no longer the magic reach lever — the algorithm relies far more on engagement, relevance and retention. Best practices: a reasonable number of relevant, targeted hashtags (tied to your niche) rather than 30 generic ones; prefer niche hashtags (less competition, more qualified audience). Treat hashtags as a useful complement, not the core of visibility.
Should you favor Reels over other formats?
Reels are currently the most algorithm-favored format for reach and new-audience acquisition — neglecting them would be a shame. But you must not bet everything on them: each plays a complementary role. Reels excel at discovery and reach; carousels at engagement and educational value (they build loyalty); stories are irreplaceable for the relationship with your community. An effective strategy combines formats by strength: Reels to attract, carousels to engage and retain, stories to nurture the bond daily. Don't put all your eggs in one basket, even the hottest one.
