稽核網站的 SEO 健康度、研究關鍵字機會、找出內容缺口,並和競爭對手做基準比較。產出一份行銷人員可以立刻執行的優先行動計畫。

## 觸發

使用者執行 `/seo-audit`,或要求 SEO 稽核、關鍵字研究、內容缺口分析、技術 SEO 檢查,或競爭對手 SEO 比較。

## 輸入

向使用者蒐集以下資訊。如果沒提供,先問再繼續:

1. **URL 或網域**:要稽核的網站,或在關鍵字研究模式下的主題/關鍵字

2. **稽核類型**:以下擇一:
   - **完整網站稽核**:涵蓋以下所有段落的端到端 SEO 檢視
   - **關鍵字研究**:替某個主題或網域找出關鍵字機會
   - **內容缺口分析**:找出競爭對手有排名、你沒有的主題
   - **技術 SEO 檢查**:可爬取性、速度、結構化資料和基礎設施問題
   - **競爭對手 SEO 比較**:和指定的競爭對手做面對面的 SEO 基準比較

   如果沒有指定,預設為 **完整網站稽核**。

3. **目標關鍵字或主題**(選填):使用者已經在鎖定、或想要取得排名的特定關鍵字

4. **競爭對手**(選填):要比較的網域或公司。如果沒提供、而稽核類型需要競爭對手資料,就用網路搜尋,依使用者的網域和關鍵字領域找出 2 到 3 個可能的競爭對手。

## 流程

### 1. 關鍵字研究

研究與使用者網域、主題或目標關鍵字相關的關鍵字。

**如果有連接 ~~SEO tools:**
- 自動拉取關鍵字資料、搜尋量、關鍵字難度分數和排名位置
- 找出網站目前有排名的關鍵字,以及哪些在進步、哪些在退步

**如果有連接 ~~product analytics:**
- 把關鍵字目標和實際的自然流量資料交叉比對,驗證哪些關鍵字真的在帶來造訪和轉換

**如果沒有連接工具:**
- 用網路搜尋研究關鍵字版圖
- 註記:「想要更精確的搜尋量和難度資料,請透過 MCP 連接像 Ahrefs 或 Semrush 這樣的 SEO 工具。稽核會自動帶入排名資料。」

針對每個關鍵字機會,評估:
- **主要關鍵字**:和使用者的產品或服務直接相關的高意圖詞
- **次要關鍵字**:輔助詞和變化形
- **搜尋量訊號**:依現有資料判斷的相對需求(高、中、低)
- **關鍵字難度**:這個詞的競爭程度(容易、中等、困難)
- **長尾機會**:具體、競爭較低且意圖明確的詞組
- **問句型關鍵字**:「how to」、「what is」、「why does」這類查詢,對應 People Also Ask 的結果
- **意圖分類**:資訊型、導航型、商業型或交易型

### 2. 頁面內 SEO 稽核

針對每個重點頁面(首頁、主要 landing page、近期部落格文章),評估:

- **Title tag**:有設定、不重複、50 到 60 字元以內、包含目標關鍵字
- **Meta description**:有設定、有吸引力、150 到 160 字元以內、包含行動呼籲
- **H1 tag**:每頁剛好一個、包含主要關鍵字
- **H2/H3 結構**:邏輯清楚的層級、在自然的地方使用次要關鍵字
- **關鍵字使用**:主要關鍵字出現在前 100 字內、整篇自然使用、不過度堆砌
- **內部連結**:頁面連到相關內容、找出孤立頁面、錨點文字具描述性
- **圖片 alt text**:所有圖片都有描述性的 alt 屬性,相關處包含關鍵字
- **URL 結構**:乾淨、可讀、包含關鍵字、沒有過多的參數或層級

### 3. 內容缺口分析

找出使用者內容策略缺少了什麼:

- **競爭對手的主題涵蓋**:競爭對手有排名、使用者網站沒涵蓋的主題和關鍵字
- **內容新鮮度**:超過 12 個月沒更新、可能正在掉排名的頁面
- **內容單薄**:深度不足以取得排名的頁面(資訊型查詢少於 300 字、缺乏實質內容)
- **缺少的內容類型**:競爭對手有用、使用者沒用的形式(指南、比較頁、名詞表、工具、範本)
- **漏斗缺口**:特定購買旅程階段(認知、考慮、決策)缺少內容
- **主題群集**:建立支柱頁面搭配輔助內容的機會

### 4. 技術 SEO 檢查表

評估影響可爬取性和排名的技術基礎:

- **頁面速度**:找出載入慢的頁面和可能原因(大圖、阻擋渲染的 script、過多的 redirect)
- **行動裝置友善度**:響應式設計、點擊目標、字體大小、viewport 設定
- **結構化資料**:可加 schema 標記的機會(FAQ、HowTo、Product、Article、Organization、Breadcrumb)
- **可爬取性**:robots.txt 設定、XML sitemap 是否存在且正確、canonical tag、noindex/nofollow 的使用
- **失效連結**:內部和外部的 404、redirect 鏈
- **HTTPS**:安全連線、混合內容問題
- **Core Web Vitals 訊號**:依可觀察的頁面行為判斷的 LCP、FID/INP、CLS 指標
- **索引狀況**:應該被索引但可能沒有的頁面、重複內容的風險

### 5. 競爭對手 SEO 比較

針對每個競爭對手,比較:

- **關鍵字重疊**:兩個網站都有排名的關鍵字,以及各自排名較高的地方
- **關鍵字缺口**:競爭對手有排名、使用者沒有的詞
- **網域權威訊號**:依反向連結概況、參照網域和內容深度判斷的相對網站強度
- **內容深度**:平均內容長度、主題涵蓋廣度、發布頻率
- **反向連結概況觀察**:連到競爭對手的網站類型、他們產出的值得被連結的內容
- **SERP 功能佔有**:哪個競爭對手出現在精選摘要、People Also Ask、圖片區塊或知識面板
- **技術優勢**:網站速度差異、行動裝置體驗、結構化資料的使用

Audit a website's SEO health, research keyword opportunities, identify content gaps, and benchmark against competitors. Produces a prioritized action plan a marketer can execute immediately.

## Trigger

User runs `/seo-audit` or asks for an SEO audit, keyword research, content gap analysis, technical SEO check, or competitor SEO comparison.

## Inputs

Gather the following from the user. If not provided, ask before proceeding:

1. **URL or domain** — the site to audit, or a topic/keyword if running in keyword research mode

2. **Audit type** — one of:
   - **Full site audit** — end-to-end SEO review covering all sections below
   - **Keyword research** — identify keyword opportunities for a topic or domain
   - **Content gap analysis** — find topics competitors rank for that you don't
   - **Technical SEO check** — crawlability, speed, structured data, and infrastructure issues
   - **Competitor SEO comparison** — head-to-head SEO benchmarking against specific competitors

   If not specified, default to **full site audit**.

3. **Target keywords or topics** (optional) — specific keywords the user is already targeting or wants to rank for

4. **Competitors** (optional) — domains or companies to compare against. If not provided and the audit type requires competitor data, use web search to identify 2-3 likely competitors based on the user's domain and keyword space.

## Process

### 1. Keyword Research

Research keywords related to the user's domain, topic, or target keywords.

**If ~~SEO tools are connected:**
- Pull keyword data, search volume, keyword difficulty scores, and ranking positions automatically
- Identify keywords the site currently ranks for and where it's gaining or losing ground

**If ~~product analytics are connected:**
- Cross-reference keyword targets with actual organic traffic data to validate which keywords are driving visits and conversions

**If tools are not connected:**
- Use web search to research the keyword landscape
- Note: "For more precise volume and difficulty data, connect an SEO tool like Ahrefs or Semrush via MCP. The audit will auto-populate with ranking data."

For each keyword opportunity, assess:
- **Primary keywords** — high-intent terms directly tied to the user's product or service
- **Secondary keywords** — supporting terms and variations
- **Search volume signals** — relative demand (high, medium, low) based on available data
- **Keyword difficulty** — how competitive the term is (easy, moderate, hard)
- **Long-tail opportunities** — specific, lower-competition phrases with clear intent
- **Question-based keywords** — "how to", "what is", "why does" queries that mirror People Also Ask results
- **Intent classification** — informational, navigational, commercial, or transactional

### 2. On-Page SEO Audit

For each key page (homepage, top landing pages, recent blog posts), evaluate:

- **Title tags** — present, unique, within 50-60 characters, includes target keyword
- **Meta descriptions** — present, compelling, within 150-160 characters, includes a call to action
- **H1 tags** — exactly one per page, includes primary keyword
- **H2/H3 structure** — logical hierarchy, uses secondary keywords where natural
- **Keyword usage** — primary keyword appears in the first 100 words, used naturally throughout, not over-stuffed
- **Internal linking** — pages link to related content, orphan pages identified, anchor text is descriptive
- **Image alt text** — all images have descriptive alt attributes, keywords included where relevant
- **URL structure** — clean, readable, includes keywords, no excessive parameters or depth

### 3. Content Gap Analysis

Identify what's missing from the user's content strategy:

- **Competitor topic coverage** — topics and keywords competitors rank for that the user's site does not cover
- **Content freshness** — pages that haven't been updated in 12+ months and may be losing rankings
- **Thin content** — pages with insufficient depth to rank (under 300 words for informational queries, lacking substance)
- **Missing content types** — formats competitors use that the user doesn't (guides, comparison pages, glossaries, tools, templates)
- **Funnel gaps** — missing content at specific buyer journey stages (awareness, consideration, decision)
- **Topic clusters** — opportunities to build pillar pages with supporting content

### 4. Technical SEO Checklist

Evaluate technical foundations that affect crawlability and rankings:

- **Page speed** — identify slow-loading pages and likely causes (large images, render-blocking scripts, excessive redirects)
- **Mobile-friendliness** — responsive design, tap targets, font sizes, viewport configuration
- **Structured data** — opportunities for schema markup (FAQ, HowTo, Product, Article, Organization, Breadcrumb)
- **Crawlability** — robots.txt configuration, XML sitemap presence and accuracy, canonical tags, noindex/nofollow usage
- **Broken links** — internal and external 404s, redirect chains
- **HTTPS** — secure connection, mixed content issues
- **Core Web Vitals signals** — LCP, FID/INP, CLS indicators based on observable page behavior
- **Indexation** — pages that should be indexed but may not be, duplicate content risks

### 5. Competitor SEO Comparison

For each competitor, compare:

- **Keyword overlap** — keywords both sites rank for, and where each site ranks higher
- **Keyword gaps** — terms the competitor ranks for that the user does not
- **Domain authority signals** — relative site strength based on backlink profiles, referring domains, and content depth
- **Content depth** — average content length, topic coverage breadth, publishing frequency
- **Backlink profile observations** — types of sites linking to competitors, link-worthy content they've produced
- **SERP feature ownership** — which competitor appears in featured snippets, People Also Ask, image packs, or knowledge panels
- **Technical advantages** — site speed differences, mobile experience, structured data usage

## Output

### Executive Summary

Open with a 3-5 sentence summary of overall SEO health. Highlight:
- The site's biggest strength
- The top 3 priorities that will have the most impact
- An overall assessment: strong foundation, needs work, or critical issues

### Prioritized Action Plan

Split recommendations into two categories:

**Quick Wins (do this week):**
- Actions that take under 2 hours and have immediate impact
- Examples: fix title tags, add meta descriptions, fix broken links, add alt text

**Strategic Investments (plan for this quarter):**
- Actions that require more effort but drive long-term growth
- Examples: build a topic cluster, create a pillar page, launch a link-building campaign, overhaul site structure

For each action item, include:
- What to do (specific and concrete)
- Expected impact (high, medium, low)
- Effort estimate
- Dependencies (if any)

## Follow-Up

After presenting the audit, ask:

"Would you like me to:
- Draft content briefs for the top keyword opportunities?
- Create optimized title tags and meta descriptions for your key pages?
- Build a content calendar based on the gap analysis?
- Dive deeper into any specific section of the audit?
- Run this same analysis for a different competitor or domain?"
