🔴 High-risk words (fines ¥200K-1M): 绝对化用语, 医疗效果承诺 - 🟡 Medium-risk words (限流/降权): 虚假宣传, 夸大描述 - 🔵 Low-risk words (建议修改): 模糊承诺, 诱导消费 - 💡 SEO tips: keyword density, title length, platform rules - ✅ Safe replacement suggestions for every banned word ### Get Suggestions (suggestions.sh) ```bash # Get replacement for specific word ./scripts/suggestions.sh "最好" # Browse all suggestions ./scripts/suggestions.sh ``` ### Configuration Create `.env` file in the skill directory: ``` CN_SEO_API_BASE=https://1341839497-2yuxt6z58d.ap-guangzhou.tencentscf.com CN_SEO_TOKEN=your-token-here # Optional: unlimited checks ``` **Free tier:** 20 checks/month (no registration needed) **Token tier:** Unlimited checks — get token via GitHub Issues ### API Endpoints | Endpoint | Method | Description | |----------|--------|-------------| | `/check` | POST | Full compliance scan (banned words + SEO) | | `/suggestions` | GET | Safe replacement suggestions | | `/health` | GET | API status check | --- ## When to Use This Skill - User wants to **check** content for SEO issues or banned words - User wants to **write** Chinese content for Baidu / Xiaohongshu / Douyin / Taobao / JD - User mentions 违禁词, 广告法, 合规, 关键词密度, or any Chinese platform SEO term - User has existing Chinese content that needs optimization --- ## Two Modes of Operation ### Mode 1: Analyze (检查模式) When the user provides existing content to check: 1. **Banned words scan** — Check for 广告法违禁词 (advertising law violations) via API 2. **Keyword density analysis** — Check if keywords are within optimal range 3. **Title placement check** — Verify keyword position in title per platform rules 4. **Content length check** — Verify content meets platform expectations 5. **Platform-specific issues** — Check for platform-specific SEO problems 6. **Output**: Detailed report with specific fixes ### Mode 2: Generate (创作模式) When the user wants new content: 1. **Clarify platform** (Baidu / Xiaohongshu / Douyin / Taobao / JD) 2. **Gather info** (topic, keywords, audience, goal) 3. **Generate content** following platform-specific rules below 4. **Auto-check** the generated content against all compliance rules (use API) 5. **Output**: Optimized content + compliance report --- ## Platform Rules ### Baidu (百度) **Title Rules:** - Primary keyword within first 15 Chinese characters - Length: 25-35 characters - Include year for freshness: "2026年最新" - Search intent modifiers: "攻略", "推荐", "对比", "怎么样", "哪个好" **Content Rules:** - Length: 1500-3000 characters for competitive keywords - Keyword density: 2-4% (Baidu penalizes stuffing more than Google) - Primary keyword in first 100 characters - Clear H2/H3 hierarchy (Baidu spider values heading structure) - Cite Baidu Baike when possible (authority signal) - Original content only — Baidu's 原创星 rewards first-published content **Common Issues:** - ❌ Keyword density < 2% → content won't rank - ❌ Keyword density > 4% → penalized as keyword stuffing - ❌ No H2/H3 structure → poor crawl efficiency - ❌ Content < 1500 chars → thin content penalty - ❌ Copied/rewritten content → 原创星 penalty --- ### Xiaohongshu (小红书) **Title Rules:** - Maximum 20 characters (shorter = higher CTR) - 1-2 emoji max in title - Power words: "绝了", "必入", "亲测", "避雷", "宝藏" - Formula: `[Emotional hook] + [Keyword] + [Specific benefit]` **Content Rules:** - Length: 300-500 characters (longer = lower completion rate) - Numbered list format preferred - Keywords in: title + first line of body + hashtags - End with question to drive comments (comment count boosts ranking) - Authentic personal voice — not marketing speak **Algorithm Factors:** - First 2 hours are critical — engagement velocity determines reach - Save rate (收藏) > Like rate (点赞) — write save-worthy content - Image: 3:4 ratio, 1080px+ width, text overlay on cover image - Hashtags: mix specific (#敏感肌防晒) + broad (#护肤) + trending (#夏日必备) **Common Issues:** - ❌ Title > 20 chars → truncated in feed, lower CTR - ❌ No emoji → lower engagement - ❌ Too many emoji → looks spammy - ❌ Content > 500 chars → low completion rate - ❌ No question at end → fewer comments → lower ranking - ❌ Marketing tone → users distrust and scroll past --- ### Douyin (抖音) **Caption Rules:** - Max 55 characters visible in feed - 1-2 keywords for search discoverability - Question format boosts engagement: "你知道...吗？" - 2-3 topic tags: #话题名 **Script Structure (15-60s videos):** ``` [Hook 0-3s]: Shocking statement or question [Problem 3-8s]: Relatable pain point [Solution 8-45s]: Demonstration [CTA last 3s]: "关注我" / "评论区扣1" ``` **Algorithm Factors:** - Completion rate is king — tight editing beats long content - Caption keywords indexed by Douyin search - Cover frame: text overlay showing keyword/topic - Trending sounds boost discoverability - Reply to early comments quickly → engagement signal **Common Issues:** - ❌ Caption > 55 chars → truncated - ❌ No topic tags → invisible in topic feeds - ❌ Hook too slow → viewers scroll away in < 3s - ❌ No CTA → missed follower conversion --- ### Taobao (淘宝) / JD.com (京东) **Product Title Rules:** - Max 30 Chinese characters (60 bytes) - Order matters: Brand + Category + Attribute + Selling point + Modifier - No keyword repetition — use synonyms - Include searchable attributes (color, size, material, occasion) **Title Formula:** `[Brand] + [Core keyword] + [Attribute 1] + [Attribute 2] + [Selling point] + [Modifier]` **Examples:** - ✅ "三只松鼠 坚果礼盒 混合装每日坚果 过年送礼 年货大礼包" - ✅ "优衣库 男士羽绒服 轻薄短款 白鸭绒 荧光色 冬季新款" - ❌ "坚果坚果礼盒每日坚果混合装坚果大礼包" (keyword stuffing) **Product Description Rules:** - 3-5 selling point bullets with keywords - Natural language with LSI keywords - Include: material, size, usage scenarios, differentiation - Trust signals: certifications, reviews, guarantees **SEO Factors:** - Fill ALL product attributes — incomplete listings rank lower - Main image: white background, product centered, no text (platform rule) - Encourage reviews containing target keywords - Correct category = visibility in category browsing **Common Issues:** - ❌ Title keyword stuffing → platform penalty - ❌ Missing attributes → lower search ranking - ❌ Wrong category → invisible in browse - ❌ Text on main image → platform demotion --- ## Banned Words (广告法违禁词) — CRITICAL Chinese advertising law (广告法) imposes heavy fines (¥200,000-1,000,000) for violations. **Every piece of content must be checked.** ### Absolute Claims (绝对化用语) — ALWAYS BANNED | Banned | Safe Alternative | |--------|-----------------| | 最好/最佳/最优 | 非常好/备受好评 | | 第一/No.1 | 销量领先/热销 | | 顶级/极致/极品 | 高端/优质 | | 独家/唯一 | 特色/甄选 | | 绝对/绝无仅有 | 深受认可/广受好评 | | 首个/首选 | 新品/精选 | | 万能/包治/根治 | 有助于/辅助改善 | ### Medical Claims (医疗效果) — BANNED FOR NON-MEDICAL PRODUCTS | Banned | Safe Alternative | |--------|-----------------| | 治愈/根治/药到病除 | 有助于改善/辅助调理 | | 减肥/瘦身 | 塑形/体态管理 | | 美白(无特证) | 提亮/焕亮 | | 祛斑(无特证) | 淡化/匀净 | | 抗皱(无特证) | 紧致/弹润 | ### Financial Claims — BANNED | Banned | Safe Alternative | |--------|-----------------| | 保本/保收益 | 稳健型 | | 零风险 | 低风险 | | 稳赚/翻倍 | 历史表现良好 | ### Platform-Specific Banned Content - **Xiaohongshu**: No WeChat redirects, no price comparisons, no fake reviews - **Douyin**: No off-platform transactions, no exaggerated claims, unmarked ads - **Taobao/JD**: No price fraud, no fake stock, no offline transaction guidance ### Quick Self-Check Search your content for these patterns — ANY match needs fixing: 1. "最" + adjective → replace 2. "第一" / "No.1" → replace 3. "绝对" / "一定" → replace 4. "根治" / "治愈" / "100%" → replace 5. "包" + effect promise → replace 6. Any medical claim on non-medical product → replace **Rule of thumb**: Use specific data instead of absolute claims. "98%用户反馈改善" is safe; "100%有效" is illegal. --- ## Keyword Research Guidance When the user needs keywords, suggest: 1. **Baidu Index** (index.baidu.com) — search volume trends + demographic data 2. **Xiaohongshu search suggestions** — type partial keyword, record autocomplete 3. **Douyin search hot list** — trending topics in category 4. **Taobao/JD search dropdown** — what buyers actually search for 5. **5118.com** — comprehensive Chinese keyword research (freemium) **Selection priorities:** - High volume + Low competition = sweet spot - Long-tail keywords (4+ chars) for new accounts - Question keywords ("...怎么样", "...好用吗") = lower competition + higher conversion - Seasonal keywords: plan 2-4 weeks ahead --- ## Output Formats ### Analysis Report (检查模式) ```markdown # SEO & Compliance Analysis Report ## 📊 Overall Score: [X/100] ### 🔴 Banned Words (违禁词) — MUST FIX | # | Word | Category | Location | Replacement | |---|------|----------|----------|-------------| | 1 | ... | 绝对化用语 | Title line 1 | ... | ### 🟡 SEO Issues — SHOULD FIX | # | Issue | Platform Rule | Current | Target | |---|-------|---------------|---------|--------| | 1 | Keyword density low | Baidu 2-4% | 1.2% | 2-4% | | 2 | Title too long | XHS ≤20 chars | 28 chars | ≤20 | ### 🟢 Passed Checks - [x] No banned words in body - [x] Hashtag strategy correct - [x] Content length appropriate ### 📝 Suggested Rewrite [Fixed version of the content] ``` ### Generated Content (创作模式) ```markdown # [Platform] SEO Content ## SEO Strategy - **Primary keyword**: [keyword] — [competition level] - **Secondary keywords**: [list] - **Target audience**: [description] - **Content goal**: [traffic / sales / awareness / followers] ## Optimized Title [title with keyword placement annotated] ## Content Body [full content, formatted per platform rules] ## Compliance Check ✅ - [x] No banned words detected - [x] Keyword density: X% (within range) - [x] Title length: X chars (within limit) - [x] Content length: X chars (appropriate) ## Hashtags / Tags [list with reasoning] ## Posting Tips - **Best time**: [platform-specific] - **Frequency**: [recommended schedule] - **Engagement**: [how to boost initial engagement] - **A/B test**: [alternative title/hook to test] ``` --- ## Important Notes - Always write in **natural, fluent Chinese** — never translated English. Chinese users detect machine translation instantly. - **Platform culture matters**: Xiaohongshu = authentic/personal; Baidu = authoritative/comprehensive; Douyin = entertaining/fast; E-commerce = specific/trustworthy. - **Compliance is non-negotiable**: 广告法 fines are real and heavy. When in doubt, use softer alternatives. - **Data > claims**: "98%用户反馈改善" beats "100%有效" — both in compliance and credibility. - **Use the API scripts** for automated scanning — they catch things manual review misses. ## 🔮 Content Prediction & Calibration (NEW) This skill now includes a **prediction calibration system** — inspired by scientific methodology: ### How It Works ``` 1. 发布前：调用 /predict 获取5维预测评分 2. 记录预测（不可修改！） 3. 发布内容 4. T+3天：复盘实际数据 vs 预测 5. 校准：根据偏差调整评分权重 6. 重复 → 越用越准 ``` ### 5 Prediction Dimensions | 维度 | 说明 | 评分 | |------|------|------| | 合规风险 | 被平台处罚/限流的风险 | 0-100（0=合规） | | 互动潜力 | 获得点赞/评论/分享的概率 | 0-100 | | 品牌安全 | 对品牌形象的影响 | 0-100（0=安全） | | 搜索可见度 | 在目标平台被搜索到的概率 | 0-100 | | AI引用概率 | 被AI搜索引擎引用的概率 | 0-100 | ### Calibration Phases - **冷启动期**（0篇复盘）：基于通用规则，准确度低 - **学习期**（1-4篇复盘）：开始校准，准确度中 - **校准期**（5+篇复盘）：基于个人数据，准确度高 ### API Endpoint ``` POST /predict Body: {"text": "内容文案", "platform": "xiaohongshu", "historyCount": 3} ``` **Why this matters**: 不复盘的每一篇，都是在折损"看见自己"的能力。预测校准让工具变成教练——越用越离不开。 --- ## 🌐 Web App — 合规通 **不想写代码？直接用Web版：** 👉 **https://1341839497-jv04655vcs.ap-shanghai.tencentscf.com/** - 免费检测5次/月 - Pro版 ¥99/月：无限次检测 + 批量检测 + API接入 - 支持小红书/抖音/百度/淘宝/京东5大平台 - 150+违禁词库 + SEO合规检查 + 安全替换建议
