Instagram Post Crafter Skill

Algorithm Signals (December 2025)

Per Adam Mosseri (January 2025), the three key ranking factors:

Signal	Weight	Notes
Watch time	#1	How long people watch (Reels)
Likes	High	More important for followers
Sends/Shares	High	Most important for reaching new audiences

Additional signals: saves, comments, completion rate, originality.

Format Selection Matrix

code

Goal: Maximum REACH → Reels
  - 30.81% average reach vs 14.45% for carousels
  - 10x viral potential for small accounts (<5K followers)

Goal: Maximum ENGAGEMENT → Carousels
  - 10% engagement rate vs 6% for Reels
  - Best for saves, comments, conversions
  - "Second chance" feature: IG shows slide 2 if slide 1 didn't get engagement

Goal: Quick post → Single image
  - Lowest reach and engagement
  - Use sparingly

Optimal strategy: Reels for growth, carousels for nurturing existing audience.

Reels: The 3-Second Rule

First 3 seconds determine everything. Reels with 50%+ retention get 3x more distribution.

Hook Formulas

code

Pattern Interrupt:
- Start mid-action (not "Today I'm going to show you...")
- Bold text overlay with surprising claim
- Direct question to viewer

Proven hooks:
- "Esto es lo que nadie te dice sobre [topic]..."
- "El error más común en [topic]..."
- "[Number] segundos para entender [concept]"
- "POV: Acabas de descubrir [thing]"
- Start with the result, then show the process

Reels Best Practices

•Length: 15-30 seconds sweet spot
•Loop: Design for seamless replay (boosts watch time)
•Audio: Trending or original (no other platform watermarks)
•Captions: Required for accessibility and silent viewing
•Post frequency: 3-5 Reels/week

Trial Reels (Test Feature)

Test content with non-followers before showing to your audience:

•Create Reel normally
•Toggle "Trial" mode before posting
•Wait 24 hours for metrics
•If it performs well, auto-publishes to followers after 72 hours

Best for: A/B testing hooks, new formats, product launches.

Carousels: The Engagement Engine

Structure

code

Slide 1: HOOK (stops the scroll)
  - Eye-catching visual
  - Punchy headline or question
  - "Swipe" indicator subtle but present

Slides 2-9: VALUE
  - One idea per slide
  - Consistent design system
  - Build narrative or list

Slide 10: CTA
  - Save this post
  - Follow for more
  - Link in bio

Best Practices

•Slides: 5-10 optimal (10 slides = highest engagement)
•Size: 1080x1350 (portrait takes more screen space)
•Swipe prompts: Arrows, "Swipe →", end mid-sentence
•Consistency: Same fonts, colors, visual style throughout
•Post frequency: 2-3 carousels/week

Data Visualization Carousels

For tacosdedatos specifically:

code

Structure for educational carousels:
1. Hook: Bold claim or surprising stat
2. Context: Why this matters
3-8. Data points with visualizations
9. Key takeaway
10. CTA: Save + Follow @tacosdedatos

Design tips:
- One chart/viz per slide
- Large, readable labels (mobile-first)
- Cite data sources for credibility
- Minimal text — let the viz speak

Hashtag Strategy (2025 Reality)

Hashtags no longer drive reach (per Adam Mosseri). They now function like SEO keywords.

Best practice:

•3-5 highly relevant hashtags only
•Mix niche + broader tags
•Place in caption (not comments — that's outdated)
•Focus effort on content quality instead

Example for tacosdedatos:

code

Posting Schedule

Optimal Times (2025 Data)

Day	Best Times
Monday	3-9 PM
Tuesday	5-8 AM, 3-7 PM
Wednesday	5 PM
Thursday	4-5 PM
Friday	4 PM
Saturday	11 AM, 5 PM
Sunday	12-3 PM

Times in PST

Weekly Cadence

code

Minimum viable:
- 3-5 feed posts/week (mix of Reels + carousels)
- Stories daily

Growth mode:
- 3-5 Reels/week
- 2-3 carousels/week
- Stories multiple times/day

Spanish-Language Patterns

LATAM Considerations

•Mexican Spanish slang over neutral Spanish
•Authenticity > polish (de-influencer trend)
•UGC-style performs well
•Consider cultural moments (Día de Muertos, etc.)

Caption Templates

Educational post:

code

[Bold statement or question]

[2-3 lines explaining the concept]
