Product Description Optimizer

Overview

This skill produces high-converting product detail page copy that balances search engine visibility with persuasive consumer messaging. It applies CPG-specific SEO frameworks, benefit-ladder copywriting, and structured data alignment to maximize both organic traffic and on-page conversion rate.

The optimizer treats every PDP as a micro-landing page — each element (title, bullets, enhanced content) has a distinct job in the discovery-to-purchase funnel.

When to Use

• Launching new SKUs on DTC or marketplace channels (Amazon, Walmart, Target+, Instacart).
• Refreshing existing listings that underperform on CTR (< 0.4%) or CVR (< 8% category avg).
• Expanding to new keywords or search verticals (e.g., "clean label," "keto-friendly").
• Migrating content across retailers with different character-limit and formatting rules.
• Preparing A+ / Enhanced Brand Content modules.

Required Inputs

| Input | Description | Example | |---|---|---| | product_name | Full SKU name including variant | "BrightClean Dish Soap, Lemon Zest, 28 oz" | | product_attributes | Key specs: size, scent, flavor, form factor, count | JSON or table | | target_keywords | Primary (1-2) and secondary (3-7) keywords with search volume | { "primary": ["natural dish soap"], "secondary": ["plant-based dish soap", "eco dish soap"] } | | category | Retail taxonomy / browse node | "Health & Household > Cleaning Supplies > Dish Soap" | | brand_voice_guide | Link or summary of tone, banned words, mandatory claims | Brand style guide excerpt | | channel | Target retailer or DTC platform | "Amazon US", "Walmart.com", "Shopify DTC" | | competitive_set | Top 3-5 competitor ASINs/URLs for gap analysis | List of URLs | | regulatory_claims | Approved on-pack claims and certifications | "USDA Organic", "EPA Safer Choice" |

Methodology

Step 1 — Keyword & Search Intent Mapping

1. Classify each keyword by intent: navigational (brand search), informational (how-to), transactional (buy/best).
2. Map primary keyword to the product title; secondary keywords distributed across bullets and description.
3. Identify long-tail modifiers from auto-suggest, "Customers also searched," and Related Search terms.
4. Calculate a Keyword Coverage Score: (matched keywords / total target keywords) × 100. Target ≥ 85%.

Step 2 — Title Construction

Apply the CPG Title Formula:

[Brand] + [Product Line] + [Key Differentiator] + [Primary Keyword] + [Size/Count] + [Variant]

• Amazon: ≤ 200 characters (80 chars mobile-visible).
• Walmart: ≤ 75 characters for title; extended title ≤ 250.
• Keep the first 60 characters front-loaded with primary keyword and core benefit.

Step 3 — Benefit-Ladder Bullet Points

Use the Feature → Advantage → Benefit (FAB) framework for each bullet:

1. Feature: What it is (ingredient, technology, format).
2. Advantage: What it does better than alternatives.
3. Benefit: What the consumer gains (time saved, peace of mind, sensory delight).

Write 5 bullets (Amazon) or 3-4 key features (Walmart). Each bullet ≤ 250 characters. Lead with the benefit, not the feature. Naturally embed one secondary keyword per bullet without stuffing.

Step 4 — Product Description / A+ Content

• Above the fold: 50-80 word paragraph restating the core value proposition with primary keyword in the first sentence.
• Storytelling module: Brand origin or use-case scenario (150-200 words).
• Comparison chart: Feature matrix vs. own portfolio (not competitors, per Amazon TOS).
• Lifestyle imagery alt text: Keyword-enriched, descriptive alt text ≤ 125 characters.

Step 5 — Structured Data & Backend Optimization

• Populate search terms / backend keywords with synonyms, abbreviations, and Spanish-language equivalents where relevant.
• Ensure itemType, material, scent, and custom attributes align with browse node expectations.
• Add schema.org Product markup for DTC (name, brand, sku, gtin, offers, aggregateRating).

Step 6 — Readability & Conversion Audit

| Metric | Target | |---|---| | Flesch-Kincaid Grade Level | 6-8 (general CPG) | | Avg sentence length | ≤ 20 words | | Power words per bullet | ≥ 1 ("effortless," "clinically proven," "dermatologist tested") | | CTA presence | At least 1 implicit CTA ("Try," "Discover," "Experience") | | Scannability | No paragraph > 3 lines on mobile |

Output Specification

output:
  title: string              # Optimized product title
  bullets: list[string]      # 3-5 benefit-driven bullet points
  description_html: string   # Rich product description with HTML
  backend_keywords: string   # Space-separated, ≤ 250 bytes
  seo_score: float           # 0-100 composite score
  readability_grade: float   # Flesch-Kincaid grade level
  keyword_coverage: float    # Percentage of target keywords used
  warnings: list[string]     # Policy violations or optimization gaps

Analysis Framework

Score each listing across five dimensions (20 points each, total 100):

1. Keyword Relevance (20): Primary keyword in title & first bullet; secondary keywords distributed; no cannibalization.
2. Persuasion Quality (20): FAB framework applied; emotional triggers present; objection handling (e.g., "no artificial dyes").
3. Compliance (20): No banned claims; certifications substantiated; retailer policy adherence.
4. Readability (20): Grade level, sentence length, scannable formatting.
5. Technical SEO (20): Backend keywords populated; structured data complete; image alt text present.

Examples

Input snippet:

• Product: "PureGlow Vitamin C Serum, 1 fl oz"
• Primary keyword: "vitamin c serum for face"
• Channel: Amazon US

Optimized Title: "PureGlow Vitamin C Serum for Face — 20% L-Ascorbic Acid, Hyaluronic Acid & Vitamin E — Brightening & Anti-Aging Face Serum, 1 fl oz"

Bullet 1 (FAB): "VISIBLY BRIGHTER SKIN IN 14 DAYS — Our stabilized 20% L-Ascorbic Acid formula penetrates deeply to reduce dark spots and even skin tone, so you wake up to a radiant, lit-from-within glow."

Guidelines

• Never make unsubstantiated health or efficacy claims; always tie claims to approved language from regulatory/legal.
• Avoid keyword stuffing — a keyword density > 3% in any content block triggers a warning.
• Do not reference competitors by name on Amazon or Walmart.
• Use sentence case for bullets on Amazon; title case for titles.
• Always run final copy through the Claims Compliance Checker skill before publishing.
• Preserve brand voice parameters: if the guide says "playful," do not write clinical copy.
