Xiaohongshu Automation & Content Strategy Research

Date: 2026-01-06 Source: Continuous learning task Purpose: Prepare for building Xiaohongshu automation tool

Executive Summary

Xiaohongshu (小红书/RedNote) has 300M+ MAU, 70% under 35. Platform tightened policies in 2025 - no newcomer protection, stricter anti-bot measures. Automation is feasible but requires sophisticated anti-detection.

Key Technical Findings

Automation Approach

Recommended Stack:

• Playwright (preferred over Selenium for 2025+)
• Cookie-based session persistence
• QR code login for initial auth
• Antidetect measures essential

Existing Open Source Projects:

• MaoTouHU/2025-xiaohongshu_ai_publisher - Selenium RPA
• ReaJason/xhs - Request wrapper
• MilesCool/rednote-mcp - MCP protocol integration
• xhs-toolkit - Claude-compatible MCP tool

Anti-Detection Requirements

1. Browser fingerprinting protection - IP masking alone insufficient
2. Playwright stealth plugins - Remove automation markers
3. Human-like patterns - Randomize timing, avoid high frequency
4. Headful mode preferred - Or proper headless bypass

Ban Risk Levels

• Shadowban (1-2 weeks): Low-quality content, promotional keywords
• Account mute (24h-30d): Spam, external links
• Permanent ban: Fake followers, fraud, illegal content

Content Strategy

2025 Algorithm Changes

• Content-value-first model (authenticity > likes)
• AI semantic recognition for ranking
• 3-hour golden period - First 3 hours determine reach
• In-depth interactions prioritized (bookmarks, revisits)

Content Requirements

• 60%+ originality required
• 600+ characters minimum
• High-res images non-negotiable
• Vertical format (3:4 ratio, 1080x1440px)

Optimal Posting

Frequency: 2-3 times weekly (consistent schedule)

Best Times (CST):

• 7:30-8:30 AM (27% higher impressions)
• 12:00-1:30 PM (34% more engagement)
• 7:00-9:30 PM (41% more comments) ← BEST

Title Formulas

1. Collection-style: "10个..."
2. Pain point + solution: "总是...？试试..."
3. Data-driven: Numbers make content substantial
4. Target audience: "上班族必看"

Banned Keywords

• Superlatives: "最好", "第一", "顶级"
• Guarantees: "100%有效", "包治"
• External links, QR codes, contact info
• Political/religious/adult content

Image Specifications

Type	Size	Ratio
Cover/Post	1080x1440px	3:4
Product	750x750px	1:1
Video	1080x1440px	9:16
Carousel	4-8 images optimal	3:4

Action Items for Our Tool

1. Use Playwright with stealth plugins
2. Implement QR code login → save cookies
3. Add random delays between actions
4. Support image upload (vertical 3:4)
5. Include keyword checker for banned terms
6. Log posting for frequency control

Risk Mitigation for Test Account

• Start with low frequency (1 post/day max)
• Use original content (no duplicates)
• Avoid promotional keywords
• Monitor for shadowban signs
• Accept potential ban (test account)
