Character Limits

Type	Limit	Notes
Standard post	280 characters	Most users
Premium	25,000 characters	X Premium subscribers
URL	Counts as 23 chars	t.co shortens all links
Emoji	~2 chars each	Varies by emoji

Optimal Lengths (Engagement)

Use Case	Characters	Purpose
General	71-100	Sweet spot for engagement
Promotional	120-130	Product/offer posts
Question	60-80	Drive replies
Retweet-friendly	~116	Leaves room for "RT @user:"

Thread Format

Structure: 3-5 connected posts; number as 1/5, 2/5, etc.
First post: Strong hook; no "thread" in first line
Last post: CTA, summary, or question
Each post: ~80 chars; can stand alone

Post Structure (Hook + Value + CTA)

Part	Ratio	Guideline
Hook	10%	First 1-2 lines; question, fact, or emotion; ~50 chars
Value	70%	Practical info; use thread for depth
CTA	20%	Call for reply, question, or action

Algorithm (Grok AI)

Signal Weights

Signal	Impact
Replies	Highest (~54-75x likes); quality > quantity
Author replies	Active reply chains ~75x visibility
Bookmark	2026 signal; saves boost recommendation
Media	Images/video ~2x; video 2-4x exposure
External links	Reduce score ~50%; prefer internal refs
Post limit	5-8/day; >10/day reduces later visibility ~80%

Content: Open questions, controversial views, stories; avoid "RT if agree" bait.

TweepCred

Threshold	Effect
< 65	Only last 3 posts enter For You
New accounts	Need +17 to appear in feed
Blue V	Auto 100 points

Monitor account health; avoid spam, bulk ops, excessive links.

Distribution

Posts tested in small group first; early interaction (first 30 min) decides reach. Niche consistency helps SimClusters match.

Link Optimization

Practice	Guideline
Penalty	External links ~-50%; Regular accounts: link posts 0% engagement since 2025
Placement	Put link in reply, not main post
Ratio	Max 1 link per 5 posts
Premium	Premium+ safest for links (~0.25-0.3% engagement)
Preview	Title ≤70 chars, description ≤200 chars; 1200×628 image

Premium Impact

Tier	Reach	Link posts
Regular	<100/post	0% engagement
Premium ($8)	~600/post	~0.25-0.3%
Premium+ ($40)	~1550/post	Safest for links

Premium ~10x reach vs Regular. If X is core channel, Premium helps.

Video

Exposure: 2-4x vs text
Length: 8-30s short video preferred
VQV: High video completion boosts score 2-3x

Content Ratio

Type	Share	Use
Value	70%	Education, how-to, insights
