SEO Skills

Keyword research, content planning, and competitor analysis with reasoning-based analysis and optional MCP enhancement.


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

Based on SEO principles and keyword structure.

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

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.
