How to Write Product Descriptions That Sell

Whether you're decluttering your home, running a side hustle, or building a full-time reselling business, one thing separates successful sellers from the rest: compelling product descriptions.

A well-written listing can mean the difference between selling an item in hours versus watching it sit for weeks. In this comprehensive guide, you'll learn exactly how to write product descriptions that attract buyers, build trust, and close sales on any marketplace.

Why Product Descriptions Matter More Than Ever

Online buyers can't touch, feel, or try your products before purchasing. Your description is their only window into what they're buying. According to e-commerce research, listings with detailed descriptions sell up to 30% faster than minimal ones.

Great product descriptions do three things:

1. Answer every question before it's asked
2. Build trust through transparency and honesty
3. Create desire by highlighting benefits, not just features

Let's dive into exactly how to achieve all three.

Crafting an Attention-Grabbing Title

Your title is the first thing shoppers see in search results. Make it count by including these essential elements:

The Perfect Title Formula

Include what the item is, the brand or model, and a key attribute like size, color, or condition.

Examples of effective titles:

• "Samsung Galaxy S21 - 128GB Black, Unlocked, Excellent Condition"
• "IKEA KALLAX Shelf Unit - White, 4x4 Cubes, Like New"
• "Levi's 501 Original Jeans - Men's Size 32x30, Vintage Wash"

Title Tips for Better Visibility

• Keep it concise: Many platforms limit titles (Mercari allows 40 characters in some regions, eBay around 80)
• Front-load important words: Put the brand and item type first since longer titles may be truncated
• Use natural keywords: Include terms buyers actually search for
• Avoid ALL CAPS: It looks spammy and reduces trust
• Include synonyms when space allows: "Couch/Sofa" or "Sneakers/Trainers" captures more searches

Think about what words a buyer would type when searching for your item. If you're selling athletic shoes, you might include both "sneakers" and "running shoes." A winter jacket could mention "puffer coat" and "down jacket." This maximizes your visibility without keyword stuffing.

Writing Descriptions That Convert

The description is where you convince buyers to click "Buy Now." Here's what to include:

1. Essential Details and Specifications

Be as precise as possible about what you're selling. Buyers shouldn't have to guess or message you for basic information.

Always include:

• Brand and model name (exact, correctly spelled)
• Size and measurements (provide actual dimensions, not just "medium")
• Material and composition (100% cotton, faux leather, solid oak)
• Color (be specific: "burgundy" not just "red")
• Quantity (if selling a set or bundle)
• Technical specifications (for electronics: storage, RAM, screen size)

Pro tip: For clothing, include actual measurements (chest, length, inseam) rather than just the tag size. A "size M" can vary wildly between brands. Buyers appreciate when you note "runs small" or "generous fit."

2. Condition Description That Builds Trust

This is crucial for used items. Be honest and detailed about the item's condition:

Condition terminology to use:

• New with tags (NWT): Never used, original tags attached
• New without tags (NWOT): Never used, but tags removed
• Like new/Excellent: Minimal to no signs of wear
• Very good: Light wear, fully functional
• Good: Visible wear, but good condition overall
• Fair: Noticeable wear, still usable

Don't hide defects — highlight them. If there's a small scratch, a missing button, or a faded spot, mention it clearly and include a photo. This builds trust because buyers know you're not hiding anything.

As experienced eBay sellers note, glossing over flaws will "result in harm to your reputation as a seller" and likely lead to returns. Transparency is better for everyone.

3. Include the History and Reason for Selling

Buyers are naturally curious about why you're selling, especially if an item is in good condition. Address this proactively:

Good reasons to mention:

• "Selling because I upgraded to a newer model"
• "Decluttering after moving to a smaller space"
• "Bought for a one-time event, no longer needed"
• "Received as a gift but not my style"

This small detail makes your listing feel more personal and credible. It reassures buyers that the item works fine and you're simply decluttering — not offloading something problematic.

4. Highlight Benefits, Not Just Features

This is the secret that separates average listings from ones that sell fast. Features tell, but benefits sell.

Transform features into benefits:

Help buyers imagine owning and using your product. If you're selling a coffee table, mention "perfect for your living room entertainment setup." A winter coat becomes "keeps you warm in temperatures down to -20°F."

5. Anticipate and Answer Questions

The most effective descriptions eliminate the need for buyers to message you. Think about common questions for your item category:

For clothing:

• Does it fit true to size?
• Is it machine washable?
• Does the color match the photos?
• Are there any pulls or pilling?

For electronics:

• Does everything work properly?
• What's the battery health?
• Are all original accessories included?
• Has it been repaired or refurbished?

For furniture:

• Can it be disassembled for transport?
• What's the weight?
• Are there any scratches or water marks?
• How old is it?

Answer these in your description, and you'll spend less time responding to messages and more time making sales.

Formatting for Maximum Readability

Online shoppers scan, not read. Make your listing easy to digest:

Use Structure to Your Advantage

Break up text with:

• Short paragraphs (2-3 sentences maximum)
• Bullet points for specifications
• Bold text for key features
• Clear section headings

Example of well-formatted description:

Sony WH-1000XM4 Wireless Headphones - Black

Experience premium sound quality with industry-leading noise cancellation. Perfect for commuting, working from home, or travel.

Condition: Excellent - used for 6 months, no visible wear

What's Included:

• Headphones with original carrying case
• USB-C charging cable
• 3.5mm audio cable for wired use
• Original box and manual

Key Features:

• 30-hour battery life
• Touch controls for volume and playback
• Speak-to-Chat automatically pauses music
• Comfortable for all-day wear

Why I'm Selling: Upgraded to the XM5s

Smoke-free home. Ships within 24 hours.

This format lets buyers quickly find the information they need, whether they're comparing specifications or checking the condition.

Platform-Specific Tips

Different marketplaces have different cultures and expectations. Here's how to adapt:

How to Sell on eBay

eBay rewards detailed listings. Their search algorithm favors descriptions with:

• Item specifics filled in (brand, size, color, material)
• Keywords in the title and description that match search queries
• Clear condition descriptions using eBay's standard terms

eBay description template essentials:

1. Opening hook with item highlights
2. Detailed specifications section
3. Condition description with photos of any flaws
4. Shipping and return policy details
5. Payment information

How to Sell on Etsy

Etsy shoppers value personality and story. While still being informative:

• Share the item's history or unique qualities
• Use descriptive, almost poetic language for handmade or vintage items
• Include measurements and care instructions
• Mention if item is vintage, handmade, or a supply

Etsy SEO tip: The first 40 characters of your title are most important. Front-load with your primary keywords (like "Vintage 1970s Leather Jacket" rather than "Beautiful Brown Leather Jacket from the 1970s").

How to Sell on Poshmark

Poshmark is social and community-oriented. Successful listings:

• Use a friendly, conversational tone
• Include style suggestions ("pairs great with high-waisted jeans")
• Mention fit details and your typical size for reference
• Engage with potential buyers in comments

Poshmark tip: Share your listings during "Posh Parties" for increased visibility. Use relevant brand and style hashtags.

How to Sell on Mercari

Mercari users appreciate straightforward, honest descriptions:

• Be upfront about condition and any flaws
• Include all dimensions and measurements
• Respond quickly to questions (the app shows your response time)
• Price items competitively — check "sold" listings for market rates

How to Sell on Facebook Marketplace

Facebook Marketplace is local-focused. Optimize for:

• Location details: Mention your general area and preferred meetup spots
• Quick communication: Respond to messages promptly
• Clear photos: Facebook compresses images, so use high-contrast, well-lit shots
• Pickup/delivery options: Specify if you offer delivery or prefer public meetup locations

How to Sell on Vinted

Vinted is huge for secondhand fashion in the US and Europe:

• Accurate size information is critical (include measurements)
• Disclose any defects — Vinted has buyer protection
• Price items to include shipping costs when possible
• Photograph items from multiple angles, including any wear

Photography Tips That Sell

Your photos are just as important as your words. Here's how to take shots that convert:

Lighting Makes Everything

• Use natural daylight whenever possible
• Shoot near a window or outside on an overcast day
• Avoid harsh flash — it washes out colors and creates unflattering shadows
• Morning or late afternoon light is most flattering

Background Matters

• Use a clean, neutral background (white wall, plain sheet, poster board)
• Remove clutter from the frame
• For dark items, use a light background (and vice versa)
• Keep the focus on your product, not your room

Show Multiple Angles

Provide at least 4-6 photos:

1. Main shot: Full item, front-facing
2. Back view: Complete the picture
3. Detail shots: Close-ups of important features
4. Size reference: Include a ruler, hand, or common object for scale
5. Defect photos: Clear shots of any wear or damage
6. Label/tag: Proves authenticity for branded items

Quality Checklist

• Images are sharp and in focus
• Colors appear accurate (check against actual item)
• Item fills most of the frame
• No blurry or dark photos
• Defects are clearly visible

Pricing Strategies That Work

The best description won't sell an overpriced item. Here's how to price right:

Research the Market

Before listing, search for similar items on your platform:

• Filter by "sold" listings to see actual selling prices
• Note the condition of items at each price point
• Check how long items typically take to sell

Price Psychology

• Include the original price when it helps ("Retails for $150, selling for $45")
• Price slightly high if you expect negotiation
• Use psychological pricing: $47 feels cheaper than $50
• Bundle items to increase perceived value

Be Clear About Negotiation

State your terms upfront:

• "Price is firm" if you won't negotiate
• "Open to reasonable offers" if you will
• "Bundle discounts available" to encourage larger purchases

Building Trust as a Seller

Trust determines whether someone buys from you versus the next seller. Here's how to build it:

Complete Your Profile

Buyers check seller profiles before purchasing. Include:

• A friendly profile photo
• A brief bio ("Decluttering enthusiast, shipping within 24 hours")
• Your location (especially important for local pickup)
• Quick response time

Communicate Professionally

• Respond to messages within a few hours
• Answer questions thoroughly and politely
• Provide tracking information promptly
• Thank buyers after the sale

Earn Positive Reviews

Reviews are your reputation. To get great ones:

• Ship items quickly and package them well
• Describe items accurately (no surprises)
• Resolve any issues promptly and fairly
• Thank buyers and ask for reviews when appropriate

Common Description Mistakes to Avoid

Even experienced sellers make these errors. Avoid them to maximize your sales:

1. Writing Too Little

Minimal descriptions like "Great condition, barely used" tell buyers almost nothing. They'll either skip your listing or bombard you with questions. Take the extra five minutes to write a complete description.

Bad example:

"iPhone 12, works great, no issues"

Good example:

"iPhone 12, 128GB, Pacific Blue, Unlocked for all carriers. Battery health at 87%. Face ID, all buttons, cameras, and speakers working perfectly. Minor scratches on the back (see photos). Includes original box and charging cable. Factory reset and ready for new owner."

2. Using Generic Stock Descriptions

If you're reselling items, don't just copy the manufacturer's description. Buyers want to know about your specific item, including its condition, history, and what's included. Generic text also hurts your search visibility since it's duplicated across thousands of listings.

3. Keyword Stuffing

While keywords help visibility, cramming irrelevant terms into your listing backfires. Don't list "Nike Adidas Jordan" when you're only selling Adidas shoes. Platforms penalize this behavior, and buyers find it unprofessional.

4. Ignoring Mobile Users

Over 70% of marketplace browsing happens on mobile devices. Keep paragraphs short, use bullet points, and ensure your photos look good on small screens. Long, unbroken text walls are especially hard to read on phones.

5. Forgetting the Call to Action

End your descriptions with clear next steps. "Message me with any questions" or "Make an offer!" encourages buyer engagement. Silence is the enemy of sales.

Category-Specific Description Tips

Different products need different approaches. Here's how to optimize descriptions for common categories:

Clothing and Fashion

• Always include measurements: Chest, length, sleeve, waist, inseam
• Note the fabric content: "60% cotton, 40% polyester" affects care and comfort
• Describe the fit: Slim, regular, relaxed, oversized
• Mention care instructions: "Machine washable" vs "dry clean only"
• Include era for vintage: "1990s vintage" helps collectors find you
• Photograph on a hanger or flat: Both options work, but be consistent

Electronics and Gadgets

• Battery health is crucial: For phones, laptops, and rechargeable devices
• List what's included: Original box, cables, adapters, manuals
• Mention any repairs: Screen replacements, battery swaps
• Include serial numbers or IMEI: For verification (you can mask part of it in photos)
• Show it powered on: Proves the item actually works
• Specify unlock status: Carrier-locked vs unlocked for phones

Furniture and Home Goods

• Dimensions are essential: Height, width, depth, weight
• Describe the material: "Real wood" vs "particle board"
• Mention assembly: "Ready to use" vs "requires assembly"
• Note weight capacity: For chairs, shelves, beds
• Include pickup logistics: Will it fit in a sedan? Requires two people?
• Photograph in natural light: Shows true colors

Collectibles and Vintage Items

• Authenticate when possible: Receipts, certificates, provenance
• Describe the era and origin: "1970s West German pottery"
• Note rarity: "Limited edition" or "1 of 500"
• Mention any markings: Signatures, stamps, labels
• Highlight imperfections honestly: "Age-appropriate wear" is acceptable
• Research comparable sales: Rare items need justified pricing

Advanced SEO Tips for Marketplace Listings

Want your listings to appear at the top of search results? Here's what most sellers don't know:

Understand Each Platform's Algorithm

• eBay: Fresh listings get a boost. Relist or revise weekly for visibility
• Etsy: Recency matters less than relevance. Focus on accurate tags and titles
• Poshmark: Sharing your own listings keeps them visible. Share at least once daily
• Mercari: Response time affects ranking. Reply to messages quickly
• Facebook Marketplace: Engagement signals (saves, messages) boost visibility

Use Long-Tail Keywords

Instead of competing for "dress," target "vintage 1960s cocktail dress size 6." Specific searches convert better because buyers know exactly what they want.

Fill in Every Optional Field

Platforms use item specifics for filtering and search. Complete every field: brand, size, color, material, style, occasion. Incomplete listings appear in fewer searches.

Test Different Titles

If an item isn't selling, try updating the title. Different keywords might reach different buyers. Track which approaches work best for your niche.

Decluttering to Sell: Turning Clutter into Cash

If you're reading this while decluttering your home, here are tips specific to selling the items you no longer need:

Start with High-Value Items

Not everything is worth selling online. Focus on:

• Electronics (even older models have value)
• Branded clothing in good condition
• Furniture that's not too heavy to ship
• Collectibles and vintage items
• Designer accessories (bags, watches, sunglasses)

Group Similar Items

Create bundles for faster sales:

• "Lot of 5 baby onesies, size 6-12 months"
• "Office supplies bundle - stapler, tape dispenser, organizers"
• "Kitchen utensil set - 12 pieces"

Be Realistic About Condition

Items from your home often have more wear than you remember. Look critically at:

• Fading or discoloration
• Stains or marks
• Missing parts or accessories
• Functional issues

Honest descriptions lead to happy buyers and positive reviews.
