Social Media Post

Create platform-optimized social media content with engagement hooks, hashtag strategy, visual direction, and scheduling recommendations. Supports single posts, threads, carousels, and cross-platform adaptations.

Process

Step 1 — Clarify Platform, Goal, and Context

Gather the inputs needed to write effective platform-native content.

Input	Required?	Notes
Platform	Yes	LinkedIn, Twitter/X, Instagram, Facebook, TikTok, Threads, YouTube Community
Topic / message	Yes	What is this post about?
Goal	Yes	Awareness, engagement, traffic, leads, community
Audience	Recommended	Who follows this account? B2B, B2C, industry?
Brand voice	Recommended	Formal, casual, witty, authoritative?
Visual assets	Optional	Do they have images, video, or need direction?
Link to include	Optional	URL for traffic-driving posts

Step 2 — Apply Platform-Specific Formatting

Each platform has its own constraints, norms, and best practices.

Platform	Character Limit	Best Formats	Optimal Length	Link Behavior
LinkedIn	3,000 chars	Text, carousel, document, video	800-1,300 chars for engagement	Links in comments perform better
Twitter/X	280 chars (free) / 25K (premium)	Text, image, thread, poll	70-100 chars for retweets, 200-280 for engagement	Links reduce reach; use sparingly
Instagram (feed)	2,200 chars	Image, carousel, Reel	125-150 chars for casual, up to 2K for storytelling	No clickable links in captions
Instagram (Stories)	Text overlay	Image/video + stickers, polls	Minimal text, visual-first	Link sticker available
Facebook	63,206 chars	Image, video, link post	40-80 chars for engagement	Native video outperforms links
TikTok	2,200 chars	Video (15s-10min)	21-34 seconds for best completion rate	Link in bio only (unless shop)
Threads	500 chars	Text, image	100-300 chars	Links allowed, carousel supported
YouTube Community	5,000 chars	Text, image, poll	200-500 chars	Links allowed

Step 3 — Write the Hook

The first line determines whether someone stops scrolling. It must appear before the "...see more" truncation.

Hook Type	Example	Best For
Bold claim	"Most marketing advice is wrong. Here's why."	Thought leadership, contrarian takes
Surprising stat	"93% of B2B buyers start with a search engine."	Data-driven content
Question	"What would you do with 10 extra hours per week?"	Engagement, community building
Story opener	"Last month I got fired. Best thing that happened."	Personal brand, narrative posts
How-to promise	"How to write a landing page in 30 minutes (framework)"	Educational content
List preview	"5 tools I use every day that cost $0:"	Utility, save-worthy content
Relatable pain	"Staring at a blank content calendar again?"	Problem-aware audiences
Contrarian	"Stop A/B testing your emails. Do this instead."	Engagement bait, strong opinions

Truncation points (characters visible before "...see more"):

• LinkedIn: ~210 characters on mobile
• Instagram: ~125 characters
• Facebook: ~80 characters on mobile feed
• Twitter/X: Full tweet visible (no truncation at 280)

Step 4 — Write the Body

Follow the appropriate structure for the platform and format.

Text post structure (LinkedIn, Twitter/X, Facebook):

[Hook — 1-2 lines]

[Space]

[Value / Story / Insight — 3-8 lines]
- Use line breaks for readability
- One idea per line
- Short sentences

[Space]

[CTA or engagement prompt]

[Hashtags (if applicable)]

Carousel / Document post structure (LinkedIn, Instagram):

Slide	Content	Purpose
1 (Cover)	Bold headline + visual hook	Stop the scroll
2	Problem statement or context	Build relatability
3-7	One key point per slide	Deliver value
8 (optional)	Summary or recap	Reinforce learning
9 (Final)	CTA — follow, save, share, link in bio	Drive action

Design guidelines for carousels:

• 1080x1350px (4:5 ratio) for maximum feed real estate
• Consistent brand colors and fonts across all slides
• Large, readable text (minimum 24pt equivalent)
• One idea per slide — do not overcrowd

Thread structure (Twitter/X, Threads):

Tweet #	Content	Purpose
1	Hook + promise ("7 lessons from scaling to $10M ARR. A thread:")	Earn the click to expand
2-N	One point per tweet, numbered	Deliver value sequentially
Final	Summary + CTA ("If this was useful, repost tweet #1 so others see it")	Drive amplification

Step 5 — Add Hashtag Strategy

Platform	Hashtag Best Practices	Recommended Count
LinkedIn	Use 3-5 relevant hashtags, mix of broad and niche	3-5
Instagram	Mix of large (1M+), medium (100K-1M), and small (< 100K) hashtags	5-15 (down from the old 30 max strategy)
Twitter/X	1-2 hashtags max, more reduces engagement	1-2
TikTok	Trending + niche hashtags in caption	3-5
Facebook	Hashtags have minimal impact	0-2
Threads	Still emerging, use sparingly	1-3

Hashtag selection framework:

1. Branded: Your company/campaign hashtag (e.g., #YourBrandName)
2. Industry: Broad category (e.g., #DigitalMarketing, #SaaS)
3. Niche: Specific community (e.g., #ContentOps, #B2BSEO)
4. Trending: Currently popular and relevant (check platform trends)
5. Descriptive: What the post is about (e.g., #MarketingTips, #CaseStudy)

Step 6 — Provide Visual Direction

If the user does not have a ready-made visual, provide direction for creating one.

Visual Type	When to Use	Specs
Static image	Most posts	1080x1080 (square), 1080x1350 (portrait), 1200x628 (landscape for links)
Carousel	Educational, list, or storytelling	1080x1350 per slide, 2-10 slides
Short video	Demos, behind-the-scenes, tutorials	9:16 for Reels/TikTok, 1:1 or 16:9 for feed
GIF / animation	Reactions, product demos	Keep under 15 seconds, loop cleanly
Screenshot	Social proof, data, tools	Annotate with highlights or callouts
Text-on-brand-background	Quote, stat, or announcement	Use brand colors and fonts
No visual (text-only)	Twitter/X text tweets, some LinkedIn	N/A

Provide a brief for each visual:

• Subject / scene description
• Text overlay (if any)
• Brand elements to include (logo, colors, fonts)
• Mood / style (e.g., clean and modern, bold and playful)

Step 7 — Recommend Posting Schedule

Optimal posting times (general guidelines — actual best times vary by audience):

Platform	Best Days	Best Times (recipient's local time)	Worst Times
LinkedIn	Tue, Wed, Thu	8-10am, 12pm	Weekends, after 6pm
Twitter/X	Mon-Fri	9-11am, 1-3pm	Late night
Instagram	Mon, Wed, Fri	11am-1pm, 7-9pm	3-5am
Facebook	Wed, Thu, Fri	9am-12pm	Late night, early morning
TikTok	Tue, Thu, Fri	7-9am, 12-3pm, 7-11pm	Varies widely

Always recommend the user check their own analytics for audience-specific insights.

Quality Checklist

• Hook appears before the platform's truncation point
• Post length is appropriate for the platform
• Formatting uses line breaks and whitespace for readability
• Hashtags follow platform-specific best practices (count and relevance)
• CTA is clear and appropriate for the goal
• Visual direction includes dimensions and a clear brief
• Tone matches the stated brand voice
• No links in Instagram captions (not clickable)
• Thread tweets can each stand alone if viewed individually
• Cross-platform adaptation is not just a copy-paste — it is reformatted for each platform
• Post does not read like an ad unless it is explicitly a promoted post
• Accessibility: image alt text described, captions for video noted

---

Edge Cases

• Cross-platform request ("post this everywhere"): Do NOT copy-paste the same text. Rewrite for each platform's format, norms, and audience. Provide platform-specific versions.
• Controversial or sensitive topic: Flag the risk. Recommend internal review before posting. Suggest neutral framing and disabling comments if needed.
• Product launch with embargo: Note the scheduled publish time clearly. Recommend drafting and scheduling in the platform's native scheduler or a tool like Buffer/Hootsuite.
• No visual assets and no design capability: Recommend free tools (Canva, Figma) with specific template suggestions. Alternatively, suggest text-only formats that perform well on the platform.
• Personal brand vs. company brand: Adjust tone accordingly. Personal brand posts are more narrative and first-person. Company posts are more polished and "we"-oriented.
• Newsjacking / trending topic: Speed matters — recommend publishing within 2-4 hours of the trend. Keep the post shorter and more reactive. Tie it clearly to the brand's expertise.
• Negative comments expected: Include a comment response framework — acknowledge, redirect, and escalate guidelines.
• Long-form content to summarize: Extract the 3-5 most shareable insights. Each insight should work as a standalone post. Link to the full piece in bio or comments.
• User wants engagement but has a small following (< 1,000): Recommend engagement-first tactics — comment on others' posts, join conversations, use niche hashtags, and tag relevant people (with permission). Organic reach is built through participation, not just posting.
