Introduction
Your Product Detail Page (PDP) is where conversion happens. Even the most optimized PPC campaigns will underperform if your listing doesn’t convert. Follow these best practices to improve CTR, CVR, and overall ad efficiency in ThinkAd and Amazon Ads.
🔹1️⃣🔹 Title Optimization
Ideal range: 120–150 characters (per Amazon guidelines; max 200).
Structure:
Brand + Core Keyword + Product Type + Key Attribute or Differentiator + Size/Color/Count (if relevant)
Example:
✅ PureSleep Bamboo Pillow Queen Size – Adjustable Firmness for Cooling Comfort & Neck Support❌ Bamboo Pillow Sleep Pillow Adjustable Neck Bed Cooling
➡️ Formatting Rules
Capitalize the first letter of each word, not all caps (per Product detail page rules).
Avoid punctuation clutter: use commas, dashes (–), or vertical bars (|) only where needed for readability.
Do not use semicolons, exclamation marks, dollar signs, or underscores (per Amazon_Title_Policy_Instruction).
Avoid repeating the same word more than twice (Amazon auto-suppresses titles for keyword repetition).
Do not include:
Promotional text (e.g., Free Shipping, 100% Quality Guaranteed).
Subjective terms (e.g., Premium, Best, Perfect).
Symbols, emojis, or decorative formatting.
➡️ Prohibited or Restricted Claims
Per Prohibited Product Claims, FDA Structure/Function Guide, and General Listing Restrictions:
❌ Do not use any health or disease claims (e.g., treats insomnia, reduces anxiety).
❌ Avoid regulated terms like anti-bacterial, anti-microbial, eco-friendly, biodegradable, non-toxic, FDA approved.
❌ Avoid medical implications (e.g., pain relief, therapy, diagnostic).
❌ Avoid false environmental or performance claims (FTC Green Guides).
✅ Acceptable phrasing: focus on general well-being, comfort, durability, or everyday performance.
➡️ SEO & Readability Balance
Place high-intent long-tail keywords at the start — this boosts ranking power.
Maintain natural readability: prioritize clarity for humans first.
Avoid keyword stuffing or unnatural phrasing.
Include variations or attributes that influence customer choice: material, color, size, pack count, or compatibility (e.g., for Oral-B Vitality).
Keywords with different spacing (e.g., omega-3, omega 3, omega3) are treated individually by Amazon’s algorithm — include at least one variant across your listing (per Best_Practices_Recomendations).
➡️ Brand and Compatibility Rules
Always start with brand name (per Product title requirements and guidelines).
If product is compatible with another brand (e.g., accessories), use the format from Selling Replacement Toothbrush Heads.docx:
[Brand/Generic] Replacement [Product Type] for [Compatible Brand/Model] – [Color, Size, Pack].
Example:
✅ Genkent Replacement Toothbrush Heads for Philips Sonicare HX6032, 4-Pack
➡️ Avoid Policy Violations
Titles that violate these principles risk:
Auto-correction or suppression by Amazon’s algorithm.
Reduced visibility in search results.
Policy warnings under Manage All Inventory → Review Listing Updates.

Use colon (:) to separate the header from the body.
Avoid semicolons unless separating short related phrases.
No emojis, symbols, or special characters (per Product bullet points requirements).
Each bullet should contain unique information (no repetition).
➡️ Content Hierarchy

➡️ SEO & Keyword Integration
Include high-intent search terms naturally within each bullet.

Each bullet contributes to 1000-character index limit for Amazon’s A9 algorithm.

Do not use HTML for styling unless using <br> or <p> (per Product detail page rules).
Maintain readability on mobile devices.

➡️ Content Focus
Your description should:
Tell the product story — what it is and who it’s for.
Reinforce emotional or practical benefits.

Designed for everyday comfort, crafted with durable cotton, built for long-term use, engineered for convenience.

Focus on 2–3 secondary long-tail keywords that were not used in the title.
Repeat one core keyword once for indexing reinforcement.
