Applies when the content brief specifies a social post, tweet, LinkedIn post, Instagram caption, Facebook post, Threads post, or Reddit submission. Covers per-platform rules, character budgets, and common pitfalls.

Social posts are short-form content written for a specific platform and published directly without human review. Every word matters, and platform conventions differ enough that one-size-fits-all writing fails.
Social posts are short-form content written for a specific platform and published directly without human review. Every word matters, and platform conventions differ enough that one-size-fits-all writing fails.
These rules apply to every social post regardless of platform:
references/platforms.md).[Link: ...], [Image: ...], [Brand Name]) appears verbatim to followers.![Visual: ...], ![Image: ...], or [Image description: ...].| Platform | Character limit | Target length | Tone |
|---|---|---|---|
| 3,000 | 300-500 chars | Professional, informative | |
| X (Twitter) | 280 | 280 chars max | Punchy, direct |
| Threads | 500 | 300-500 chars | Conversational, authentic |
| 2,200 | 200-300 chars | Story-driven, visual-first | |
| 63,000 | 400-600 chars | Conversational, personal | |
| 40,000 | 500-1,000+ chars | Community-first, value-driven |
The first line determines whether someone reads the rest. On most platforms, only the first 1-2 lines display before "See more." Front-load the most compelling idea.

Match the platform's conversational norms:
Stay within the target range, not just the hard limit. A LinkedIn post that fills all 3,000 characters reads like a blog post crammed into a feed. A tweet that hits exactly 280 characters leaves no room for a quote-retweet comment.
| Platform | Hashtag count | Notes |
|---|---|---|
| 3-5 | Relevant industry terms | |
| X | 2-3 | Trending or niche terms |
| Threads | 0-2 | Optional, keep minimal |
| 10-15 | Mix of broad and niche | |
| 1-3 | Minimal, optional | |
| 0 | Not used on Reddit |
Place hashtags at the end of the post, not inline. Inline hashtags break reading flow.
Every post needs a purpose, but not every post needs a hard CTA. Match the CTA strength to the platform:
