Keyword Research Framework

Keyword Tier Classification

Tier 1 — Head Terms (Primary keywords):

• Monthly searches: 10,000+
• Competition: Very High
• Use in: Title (first 60 chars), backend
• Strategy: Must rank here eventually, but may need 6-12 months

Tier 2 — Core Keywords (Secondary keywords):

• Monthly searches: 1,000-10,000
• Competition: Medium-High
• Use in: Title, bullet points, backend
• Strategy: Primary target for new listings — achievable with 50+ reviews

Tier 3 — Long-tail Keywords (Conversion keywords):

• Monthly searches: 100-1,000
• Competition: Low-Medium
• Use in: Description, backend, PPC exact match
• Strategy: Launch focus — win these first to build velocity

Tier 4 — Niche Keywords (Discovery keywords):

• Monthly searches: <100
• Competition: Very Low
• Use in: Backend search terms, PPC broad match
• Strategy: Passive traffic, zero cost to rank for

Keyword Extraction from Listing Text

From a product title/bullets, extract keywords by:

1. Identify product type (noun phrase)
2. Extract all modifiers (size, color, material, use case)
3. Generate all meaningful combinations
4. Add related synonyms and alternative terms
5. Add use-case and problem-based phrases

Example for "Stainless Steel Water Bottle 32oz":

Primary: water bottle, stainless steel water bottle
Modifiers: 32oz, large, insulated, vacuum, leak-proof, BPA free
Use cases: hiking, gym, sports, outdoor, camping, travel
Problem-based: keeps water cold, hot coffee thermos
Synonyms: tumbler, flask, canteen, hydration bottle
Long-tail: 32oz insulated water bottle, stainless steel gym bottle leak proof

Reverse Lookup Logic (Manual ASIN Analysis)

When given an ASIN, analyze by:

1. Extract all words from title, bullets, description
2. Generate keyword permutations
3. Identify brand terms vs. generic terms
4. Cross-reference with category common keywords
5. Score by estimated commercial intent

Keyword Gap Analysis

Given your ASIN vs. competitor ASIN:

Your keywords:       [A, B, C, D, E]
Competitor keywords: [B, C, D, F, G, H]
Gap keywords:        [F, G, H] — competitor has these, you don't
Unique to you:       [A, E] — your advantage, protect these

CPC Bid Intelligence

Bid estimation by competition level:

Very High competition (Tier 1): $1.50 - $3.00+ CPC
High competition (Tier 2):      $0.80 - $1.50 CPC
Medium competition (Tier 3):    $0.30 - $0.80 CPC
Low competition (Tier 4):       $0.10 - $0.30 CPC

Bid strategy by campaign type:

• Exact match: Bid at estimated CPC
• Phrase match: Bid at 80% of exact
• Broad match: Bid at 60% of exact
• Auto campaign: Start at $0.50, scale based on ACOS

Backend Search Terms (249 Characters)

Rules for backend keyword field:

• No commas needed — spaces work
• No repeat words — every character counts
• Include misspellings of your product name
• Include complementary product terms
• No ASINs, brand names of competitors, or prohibited terms
• Use singular forms only (Amazon pluralizes automatically)

Template:

[synonyms] [materials] [use cases] [compatible items] [problem solved] [occasion] [demographic]

Listing Keyword Injection

Title formula: [Brand] [Primary Keyword] [Key Feature] [Size/Variant] [Secondary Keyword]

Bullet point structure:

• Bullet 1: Primary keyword + biggest benefit
• Bullet 2: Secondary keyword + feature proof
• Bullet 3: Long-tail keyword + use case
• Bullet 4: Trust signal (certifications, compatibility)
• Bullet 5: Guarantee / customer promise + brand keyword

Keyword Scoring Matrix

Score each keyword on 4 factors (1-5):

1. Search volume — how many searches per month
2. Relevance — how closely it matches your product
3. Competition — how hard to rank (5=very easy)
4. Intent — how likely searcher is to buy (5=high purchase intent)

Priority Score = (Volume + Relevance + Competition + Intent) / 4 Focus first on keywords scoring 4.0+
