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.

Methodology
Step 1 — Keyword & Search Intent Mapping
- Classify each keyword by intent: navigational (brand search), informational (how-to), transactional (buy/best).
- Map primary keyword to the product title; secondary keywords distributed across bullets and description.
- Identify long-tail modifiers from auto-suggest, "Customers also searched," and Related Search terms.
- 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:
- Feature: What it is (ingredient, technology, format).
- Advantage: What it does better than alternatives.
- 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 |

Analysis Framework
Score each listing across five dimensions (20 points each, total 100):
- Keyword Relevance (20): Primary keyword in title & first bullet; secondary keywords distributed; no cannibalization.
- Persuasion Quality (20): FAB framework applied; emotional triggers present; objection handling (e.g., "no artificial dyes").
- Compliance (20): No banned claims; certifications substantiated; retailer policy adherence.
- Readability (20): Grade level, sentence length, scannable formatting.
- 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.
