The Iron Law

NO METRICS WITHOUT SOURCE DECLARATION

Always state whether analysis is reasoning-based or MCP-enhanced. Violating the letter of this rule is violating the spirit.

Data Source Detection

At the start of any SEO task, identify available data sources:

Check for MCP Tools

IF Ahrefs MCP available (tools contain ahrefs_):

• Use for: Volume, Keyword Difficulty, Backlinks, Domain Rating
• Confidence: HIGH
• Label: "Analysis enhanced with Ahrefs data"

IF SEMrush MCP available (tools contain semrush_):

• Use for: Volume, Keyword Difficulty, Competitor keywords, Domain overview
• Confidence: HIGH
• Label: "Analysis enhanced with SEMrush data"

IF GSC MCP available (tools contain gsc_ or search_console):

• Use for: Current rankings, Impressions, Clicks, CTR
• Confidence: HIGH
• Label: "Analysis enhanced with Search Console data"

IF user pastes data:

• Parse CSV/TSV format
• Confidence: MEDIUM
• Label: "Analysis based on provided data"

IF no MCP and no paste:

• Use reasoning based on SEO principles
• Confidence: MEDIUM
• Label: "Reasoning-based analysis"

Keyword Research

When to Use

• "find keywords for [topic]"
• "keyword research for [industry]"
• "what should I rank for"
• "analyze these keywords"

Data Source Gate

BEFORE analyzing keywords:

1. CHECK for MCP tools (Ahrefs, SEMrush, GSC)
2. CHECK for pasted data from user
3. DECLARE data source in output header

Analysis Framework

Factor	With MCP/Data	Reasoning-Based
Volume	Exact number from API	"Likely [high/medium/low] based on term type"
Difficulty	KD score from API	"Likely [easy/medium/hard] based on keyword structure"
Intent	Same analysis method	Same analysis method
Position	From GSC if available	"Unknown - connect GSC for current rankings"

Output Format

With MCP Enhancement:

📊 KEYWORD ANALYSIS

Content Planning

When to Use

• "plan content for [topic]"
• "create content calendar"
• "content brief for [keyword]"
• "what should I write about"

Prerequisites Gate

BEFORE creating content plans:

1. ✅ Keyword analysis done? (If not: do keyword research first)
2. ✅ Brand context loaded? (If not: /brand switch [name])
3. ✅ Declare data sources in output

Placeholder Prohibition

NEVER output placeholders like:

• "[Topic]"
• "[First Step]"
• "Main Point 1"

Either generate specific content or ask for the information.

Content Brief Format

📝 CONTENT BRIEF

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📌 **Title:** [Actual title]
🎯 **Target Keyword:** [keyword]
📊 **Word Count:** [range] words
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

## Search Intent

Competitor Analysis

When to Use

• "analyze [competitor]"
• "competitor analysis"
• "find competitor keywords"
• "SEO gap analysis"

Data Source Options

With Ahrefs/SEMrush MCP:

• Pull competitor's top keywords
• Get backlink profile
• Domain authority/rating
• Traffic estimates

Without MCP:

• Analyze their visible content
• Review their site structure
• Infer target keywords from page titles/URLs
• Use web search to research competitor public content

---

Red Flags - STOP

If you catch yourself:

• Stating specific numbers (5,000 searches) without MCP data or paste
• Claiming "difficulty is 45" without KD source
• Saying "this is a quick win" without ranking data
• Making competitor claims without evidence

STOP. Declare it as reasoning-based or ask for data.

---

Verification Checklist

BEFORE presenting SEO analysis:

• Data source declared in header?
• Confidence level stated?
• Numbers sourced or marked as estimates?
• No unsupported "quick win" claims?

If any unchecked: Fix before presenting.
