What Data to Provide

SIF Framework

S — Search Discovery

How easily can buyers find your listing?

Search discovery factors:

1. Primary keyword in title — must appear in first 60 characters
2. Keyword indexing — is Amazon actually indexing your keywords?
3. Search rank position — where do you appear for key terms?
4. Ad coverage — are you bidding on all critical terms?

Search audit checklist:

[ ] Primary keyword in title (first 60 chars)?
[ ] Top 3 keywords appear in title?
[ ] All bullet points contain at least 1 target keyword?
[ ] Description is keyword-rich?
[ ] Backend search terms filled (249 chars)?
[ ] Backend has no word repetition from title/bullets?
[ ] Backend includes misspellings, synonyms, long-tails?
[ ] Running Sponsored Products on exact match for top 10 keywords?
[ ] Auto campaign running to discover new keywords?

Search score (0-25):

• Title keyword presence: 0-8 pts
• Backend completeness: 0-7 pts
• Ad coverage: 0-5 pts
• Search rank on key terms: 0-5 pts

I — Index Verification

Is Amazon indexing your keywords?

Indexing check method:

• Search: site:amazon.com/dp/[ASIN] keyword
• Or search the keyword on Amazon and check if your ASIN appears
• Note: Amazon drops keywords that don't drive conversions

Common indexing failures:

Reason                          Fix
Too many keywords in title      Prioritize top 5 only
Duplicate keywords              Remove repeats from backend
Restricted/prohibited terms     Replace with compliant alternatives
Non-English characters          Use ASCII equivalents
Keyword not in any field        Add to backend search terms

Index score (0-25):

• Primary keyword indexed: 0-10 pts
• All Tier 1-2 keywords indexed: 0-10 pts
• No prohibited terms detected: 0-5 pts

F — Conversion Funnel

Once a buyer lands on your listing, does it convert?

Conversion funnel stages:

Search results → Click (driven by main image + title + price)
                    ↓
Product page → Add to Cart (driven by images, bullets, price, reviews)
                    ↓
Cart → Purchase (driven by trust signals, price, delivery)

Conversion funnel audit:

Stage 1 — Click-through (CTR):

[ ] Main image: white background, product fills 85%, no text overlays
[ ] Title: keyword-rich AND human-readable, not stuffed
[ ] Price: competitive within ±10% of top 3 competitors
[ ] Review count: minimum 15+ reviews to compete
[ ] Prime badge: FBA/FBM with Prime eligibility
[ ] CTR benchmark: >0.5% for search results

Stage 2 — Page conversion (CVR):

[ ] 7+ high-quality images (main + lifestyle + infographic + detail)
[ ] Video present (boosts CVR by 20-30%)
[ ] All 5 bullet points used, benefit-led format
[ ] A+ content present (Brand Registry required)
[ ] Price anchored appropriately (MSRP shown if discounted)
[ ] Review rating ≥4.0 stars
[ ] FAQ section answered (reduces purchase hesitation)
[ ] CVR benchmark: >10% for category (varies widely)

Stage 3 — Cart to purchase:

[ ] Fast delivery promise (2-day Prime preferred)
[ ] Return policy visible (30-day free returns = trust signal)
[ ] Secure transaction badge
[ ] No negative red flags in Q&A section
[ ] Seller feedback rating >95%

Funnel score (0-50):

• CTR optimization: 0-15 pts
• Page CVR optimization: 0-25 pts
• Trust signals: 0-10 pts

SIF Score Interpretation

Total SIF Score (0-100):
90-100: Elite listing — maximize ad spend, listing is a machine
75-89:  Strong listing — minor improvements for incremental gains
60-74:  Good listing — targeted improvements will boost performance significantly
45-59:  Average listing — significant work needed on multiple fronts
<45:    Poor listing — comprehensive rewrite required before scaling ads

Title Optimization Framework

Title formula: [Brand] + [Primary Keyword] + [Top Feature] + [Secondary Keyword] + [Benefit/Use Case]

Title scoring:

• Character count: 150-200 chars (not <80, not >200)
• Primary keyword in first 40 chars: essential
• 2-3 key selling features: yes
• Mobile truncation (first 80 chars): must be compelling on mobile
• Readability: must make sense as a sentence

Example:

Before: "Water Bottle Stainless Steel Insulated 32oz BPA Free Lid Straw Sport School Office"
After: "HydroMax Insulated Water Bottle 32oz | Stainless Steel, Leak-Proof Lid, Stays Cold 24hrs | BPA-Free Flask for Gym, Hiking, School"

Bullet Point Framework

5-bullet structure:

Bullet 1: [Primary benefit + primary keyword] — your biggest selling point
Bullet 2: [Key feature + secondary keyword] — technical proof of benefit 1
Bullet 3: [Use case/versatility + long-tail keyword] — broadens appeal
Bullet 4: [Trust signal + quality claim] — certifications, compatibility, warranty
Bullet 5: [Customer promise + brand keyword] — satisfaction guarantee, service

Format rules:

• Start with ALL CAPS benefit statement: "LEAK-PROOF LID GUARANTEED —"
• Follow with specific evidence: "triple-seal technology prevents spills..."
• End with use case or emotional benefit

PPC Campaign Optimization

3-campaign structure:

Campaign 1: Exact Match — top 20 keywords, aggressive bids
Campaign 2: Phrase Match — broad keyword variations
Campaign 3: Auto — discovery, harvest new keywords weekly

Weekly tasks:
1. Harvest converting keywords from auto → add to exact/phrase
2. Negate non-converting terms from all campaigns
3. Adjust bids: raise for ACOS <target, lower for ACOS >target
4. Check new keyword opportunities from search term reports

Bid optimization matrix:

ACOS < 15%:    Raise bid 20% — underinvesting in a winner
ACOS 15-25%:   Maintain — at target range
ACOS 25-40%:   Lower bid 15% — marginal profitability
ACOS > 40%:    Lower bid 30% or pause — burning cash
0 impressions: Raise bid significantly or check keyword match
0 conversions >50 clicks: Negative match + listing review
