Auction Listing Text Optimization Guide
On marketplaces like eBay, Amazon, and Poshmark, your listing text is the primary sales tool. Research consistently shows that listings with 150–300 word descriptions sell 1.5–2x faster than those with fewer than 50 words. This guide covers platform-specific character limits, title optimization strategies, and description structures that maximize your sell-through rate.
Platform Character Limits
| Platform | Title Limit | Description Limit | Recommended Title | Recommended Description |
|---|---|---|---|---|
| eBay | 80 chars | Unlimited (practical) | 60–75 chars | 200–800 words |
| Amazon Marketplace | 200 chars | 2,000 chars | 80–150 chars | 200–500 words |
| Poshmark | 80 chars | 1,500 chars | 50–75 chars | 100–300 words |
| Facebook Marketplace | 100 chars | 1,000 chars | 50–80 chars | 80–200 words |
| Etsy | 140 chars | Unlimited | 80–130 chars | 200–600 words |
| Depop | No separate title | 1,000 chars | N/A | 100–250 words |
Use 75–100% of the title character limit. Search algorithms weight title keywords heavily, so leaving space unused means missed discovery opportunities. For descriptions, aim for 30–60% of the maximum—enough detail to answer buyer questions without overwhelming them.
Title Writing Strategy
Your title must pack brand, product, condition, and key features into a tight character budget. Here's an effective allocation for an 80-character eBay title:
- Brand name (10–20 chars): "Nike", "Apple", "Levi's"—brand searches indicate high purchase intent
- Product name / model (15–30 chars): "Air Max 90", "iPhone 15 Pro 256GB"—use the official name
- Condition / key feature (10–20 chars): "New with Tags", "Excellent Condition", "Limited Edition"
- Supplementary keywords (10–15 chars): "Free Shipping", "Size M", "Black"
Avoid filler words like "LOOK!" or "L@@K" or "AMAZING DEAL!!!"—they waste characters and reduce buyer trust.
Description Structure
| Section | Word Count | Content |
|---|---|---|
| Opening hook | 15–30 words | Brief greeting and one-line product summary |
| Product details | 50–100 words | Brand, model, size, color, material, purchase date |
| Condition | 30–80 words | Usage frequency, specific flaws with photo references |
| Included items | 15–40 words | Box, manual, charger, warranty card |
| Shipping info | 15–40 words | Method, estimated delivery, packaging |
| Policies | 20–50 words | Returns, offers, bundling options |
Category-Specific Guidelines
| Category | Recommended Length | Priority Information |
|---|---|---|
| Clothing & Shoes | 150–250 words | Exact measurements, fabric, fit description, wear count |
| Electronics | 200–400 words | Model number, specs, battery health, included accessories |
| Books & Media | 80–150 words | Edition, condition of pages/cover, markings |
| Collectibles | 200–400 words | Authenticity details, provenance, storage conditions, rarity |
| Furniture | 200–300 words | Dimensions (W×D×H), weight, assembly required, delivery options |
Search Algorithm Tips
- Include both formal and common names: "Nintendo Switch" and "game console" capture different search behaviors
- Add model numbers: Buyers searching "MWP22LL/A" know exactly what they want and are ready to buy
- Use relevant hashtags where supported: 5–10 hashtags totaling 50–80 characters on platforms like Poshmark and Mercari
- Avoid keyword stuffing: Listing unrelated brand names or categories can result in listing removal
Conclusion
Effective marketplace listings use 60–75 characters for titles and 150–400 words for descriptions, adjusted by category and platform. Front-load titles with brand and product names, structure descriptions to preemptively answer buyer questions, and include specific condition details for items over $50.
