How to Write Reselling Listings That Sell: Title, Description & SEO by Platform

You sourced a $400 jacket for $12 at Goodwill. Steamed it. Photographed it under perfect lighting. Listed it. And then... nothing. Two weeks of crickets. Meanwhile, a seller across town listed the same brand, same style, same condition and sold it in three days for $180.

The difference wasn't the item. It was the words. The title. The description. The way those words lined up with what buyers actually type into the search bar on that specific platform. Listing copywriting is the most undervalued skill in reselling. Great photos get the click. Great copy closes the sale. And the rules are different on every single marketplace.

This guide covers the platform-specific formulas, character limits, and description strategies that actually move inventory. No generic advice. No "just write a good description." Concrete templates you can use today on Poshmark, eBay, Depop, and Etsy.

Why Your Listing Copy Matters More Than You Think

Every marketplace runs a search algorithm. When a buyer types "Nike Air Max 90 women size 8," the platform scans listing titles, descriptions, tags, and item specifics to decide what to show. Your listing copy is your application to appear in those results. Bad copy means you never enter the race.

But search visibility is only half the equation. Once a buyer lands on your listing, the description has to do the selling. It has to answer their unspoken questions: Is this the right size? What's the condition? Does this seller seem trustworthy? A well-written description reduces "is this still available?" messages, prevents returns from mismatched expectations, and builds enough confidence for someone to hit Buy Now without overthinking it.

The catch is that each platform has different character limits, different search logic, and different buyer expectations. A title that crushes it on eBay will underperform on Depop. A description style that works on Poshmark will feel sterile on Etsy. You have to adapt.

Poshmark: Storytelling Meets Search

Poshmark gives you 80 characters for your title and a description field where the sweet spot is 150-300 words. The platform's search is less sophisticated than eBay's, which means your title carries enormous weight. Poshmark buyers also tend to browse more casually -- they scroll feeds, attend Posh Parties, and discover items through shares. Your copy needs to work for both direct search and passive discovery.

The Poshmark Title Formula

Pack the highest-value keywords into those 80 characters. The order matters -- Poshmark's search gives more weight to words that appear earlier in the title. Here's the formula that consistently performs:

[Brand] [Item Type] [Key Feature/Style] [Size] [Color]

• Good: "Nike Air Max 90 Running Shoes Women Size 8 White Pink" (54 chars)
• Good: "Lululemon Align Leggings 25" High Rise Black Size 6" (54 chars)
• Bad: "Beautiful shoes!! Great condition must see!!" (wastes every character on fluff)
• Bad: "Nike shoes" (leaves 68 characters of searchable space empty)

Never use special characters, excessive punctuation, or all-caps. Poshmark's search treats "NWT" and "NWOT" as searchable keywords, so include them in the title when applicable. Many buyers filter specifically for new-with-tags items.

Poshmark Description Strategy

Poshmark descriptions should read like a knowledgeable friend recommending an item. The platform's social DNA rewards personality over sterile product specs. But personality without information doesn't sell either.

Structure your description in this order:

1. Opening hook: One sentence about why this item is worth attention. "This is the jacket that sells out every fall season."
2. Key details: Brand, size, color, material, measurements (laid flat). Bullet points or short lines work best.
3. Condition notes: Be specific and honest. "Worn twice, no signs of wear" is better than "excellent condition." If there are flaws, describe them precisely -- it builds trust and prevents returns.
4. Style context: One sentence on how to wear it or who it's perfect for. "Pairs perfectly with high-waisted jeans for a casual weekend look."
5. Search-friendly closing: Naturally work in related keywords. "Similar to Athleta and Outdoor Voices styles." This catches searches for those adjacent brands.

Keywords in your Poshmark description do contribute to search visibility. Mentioning related brands, style names, and specific details like "cropped," "oversized," or "vintage" expands the searches where your listing can appear. But don't stuff. Write naturally and let the keywords happen.

eBay: Structured Data Wins the Game

eBay is the most search-driven marketplace you'll sell on. The platform processes hundreds of millions of listings, and its Cassini search engine is sophisticated. Your title gets 80 characters, and eBay's research shows that titles using 75+ characters with 15-18 words correlate with higher daily sales. But the real differentiator on eBay isn't the title alone -- it's item specifics.

The eBay Title Formula

eBay titles need to be dense with relevant search terms. Unlike Poshmark, storytelling has no place here. Every character should be a keyword a buyer might search for.

[Brand] [Product Line] [Item Type] [Key Attributes] [Size] [Color] [Condition]

• Good: "Nike Air Max 90 Women Running Shoes Size 8 White Pink Athletic Sneakers" (73 chars)
• Good: "Patagonia Better Sweater Full Zip Fleece Jacket Men Large Blue Hiking" (73 chars)
• Bad: "LOOK!! Amazing Nike shoes cheap price fast shipping L@@K" (filler, no searchable data)
• Bad: "Shoes" (you're competing against 40 million other shoe listings)

Avoid filler words in eBay titles. Words like "amazing," "cute," "must-have," and "wow" waste characters and add zero search value. eBay's algorithm doesn't care about adjectives. It cares about nouns, brand names, model numbers, sizes, and materials.

Item Specifics: eBay's Secret Weapon

Here's what separates casual eBay sellers from profitable ones: item specifics. eBay gives you structured fields for brand, size, color, material, style, pattern, occasion, and dozens of category-specific attributes. Filling out every single one is non-negotiable.

Why? Because eBay's search filters depend on item specifics. When a buyer searches "Nike shoes" and then filters by Size 8, Color White, and Condition Pre-owned, your listing only appears if those item specifics are filled in. Listings with incomplete item specifics get filtered out of these refined searches, which is where most serious buyers end up.

• Fill out every required item specific, plus every optional one that applies
• Make sure your item specifics match your title (inconsistencies confuse both the algorithm and buyers)
• Use the exact values from eBay's dropdown menus when available -- custom values are searchable but don't appear in filter results
• Check competitor listings in your category to see which item specifics they're using

eBay Description Approach

eBay descriptions are less important for search ranking than titles and item specifics, but they're critical for conversion. Buyers on eBay expect detailed, factual descriptions. No storytelling. No vibes. Just information.

Use a clean, scannable format:

• Brand and model name (repeat from title for clarity)
• Exact measurements -- shoulder to shoulder, pit to pit, length, waist, inseam. Buyers on eBay are more measurement-conscious than on any other platform
• Material composition from the care tag
• Condition details with specific callouts for any wear, flaws, or modifications
• What's included (original packaging, dust bag, extra laces, etc.)
• Shipping and handling notes if relevant

Keep the HTML simple. eBay's description limit is technically massive (500,000 characters including HTML), but heavy templates with complex formatting can slow page load and look broken on mobile. Plain text with bold headers and line breaks outperforms fancy HTML templates every time.

Depop: Vibes, Hashtags, and Gen Z Search Behavior

Depop is a fundamentally different marketplace. The buyer demographic skews Gen Z. The browsing behavior is more like Instagram than Amazon. And the listing format combines your title and description into a single 1,000-character field with up to 5 hashtags. That shared character limit means every word has to pull double duty -- searchable and engaging at the same time.

Writing for Depop's Combined Field

Since Depop doesn't separate title and description, the first line of your listing acts as the title in search results and the Explore page. Make it count.

First Line (the de facto title): Lead with the most searchable terms -- brand, item type, key aesthetic. Then get specific.

• Good first line: "Vintage Nike windbreaker jacket - 90s color block, oversized fit"
• Good first line: "Y2K baby tee with rhinestone butterfly - deadstock with tags"
• Bad first line: "Super cute top I bought but never wore!!" (zero search value)
• Bad first line: "DM me for details" (tells the algorithm nothing)

After the first line, shift into a casual, personality-driven description. Depop buyers respond to voice. They want to know the vibe, not just the specs. That said, you still need the basics: size, measurements, material, and condition. Just deliver them conversationally.

A strong Depop description reads something like: "The perfect oversized windbreaker for layering. Authentic vintage Nike from the early 90s. Fits like a modern L/XL. Pit to pit 26 inches, length 28 inches. Lightweight nylon shell. No flaws -- this thing is in incredible shape for its age. Would look amazing over a tank with wide-leg jeans."

Depop Hashtags: 5 Tags, Make Them Count

You get exactly 5 hashtags per listing on Depop. These are searchable keywords that help buyers find your item beyond your followers. The strategy is completely different from Instagram hashtags.

• Use aesthetic-based tags over generic ones. #gorpcore, #cottagecore, #y2k, #barbiecore, and #darkacademia outperform #fashion or #clothing because Depop buyers search by aesthetic
• Include one brand tag if the brand has a following: #vintageNike, #levis501, #carhartt
• Include one item-type tag: #windbreaker, #cargopants, #babytee
• Avoid misleading tags. Depop actively penalizes tag spam and irrelevant hashtags. If your item isn't Y2K, don't tag it #y2k
• Rotate tags seasonally. #festivaloutfit peaks in spring. #cozycore peaks in fall. Match your tags to what buyers are searching for right now

The hashtags that perform best on Depop reflect specific buyer intent. Someone searching #gorpcore knows exactly what they want. Someone searching #clothes is just browsing. Target the intentional searchers.

Etsy: Long-Tail Keywords and the 13-Tag System

Etsy's search engine is the most keyword-dependent of any major marketplace. You get a 140-character title and 13 tags of up to 20 characters each. That's 13 separate opportunities to match a buyer's search query. Most Etsy sellers waste at least half of them. For a deeper dive into Etsy's tag system specifically, check out our Etsy SEO tag optimization guide.

The Etsy Title Formula

Etsy's 2026 algorithm favors natural, conversational phrases over keyword-stuffed titles. But you still need to front-load the most important terms because only the first 40-50 characters display in search results on mobile.

[Primary Keyword Phrase] [Secondary Details] [Occasion/Recipient] [Material/Style]

• Good: "Personalized Leather Wallet for Men, Anniversary Gift, Engraved Bifold with Initials" (89 chars)
• Good: "Vintage Botanical Print Set of 3, Wildflower Wall Art, Farmhouse Gallery Decor" (83 chars)
• Bad: "Wallet" (wastes 133 characters of searchable title space)
• Bad: "BEST GIFT EVER handmade wallet cheap price free shipping look here" (no product specifics)

Use natural separators like commas or dashes between phrases. Etsy's algorithm parses these as phrase boundaries and can match on individual segments. "Personalized leather wallet, anniversary gift for him" can match searches for "personalized leather wallet" AND "anniversary gift for him" separately.

The 13-Tag Strategy

Each tag should expand your listing's reach into searches your title doesn't cover. Never duplicate your title keywords in your tags -- Etsy already indexes your title separately. Tags are your chance to cast a wider net.

Distribute your 13 tags across four categories:

• 3-4 tags for what the item IS (alternate product descriptors): "mens bifold wallet," "leather card holder," "slim wallet"
• 3-4 tags for WHO it's for or WHEN they'd buy it: "gift for husband," "anniversary present," "groomsmen gift"
• 2-3 tags for style or aesthetic: "minimalist wallet," "rustic leather goods," "handcrafted accessory"
• 2-3 tags for use-case or long-tail variations: "front pocket wallet," "travel wallet men," "everyday carry"

Use multi-word phrases for every tag. The tag "leather wallet men" is one tag that matches three different search terms. Single-word tags like "leather" or "wallet" are too broad to rank for and waste your limited slots. Etsy can break multi-word tags apart for matching, but it can't combine single-word tags into phrases.

Etsy Description and Attributes

Etsy's official guidance is that description text does not directly affect search ranking -- tags and titles are what determine search matching. However, the first 40 characters of your description appear as a preview snippet in search results, so that opening line matters for click-through rate.

Write descriptions for the buyer, not the algorithm. Lead with the most compelling detail or benefit, then follow with specifications, materials, dimensions, care instructions, and shipping details. Etsy buyers expect thoroughness, especially for handmade and vintage items where they can't rely on standardized product specs.

Don't neglect attributes. Etsy's category-specific attributes (material, color, occasion, recipient, style) function similarly to eBay's item specifics. They feed directly into search filters. If a buyer filters by "Gift for: Husband" and you haven't set that attribute, your listing is invisible to that search.

Keyword Research Basics for Resellers

You don't need expensive keyword tools. Every platform gives you free research data if you know where to look.

The Search Bar Method

Start typing in any marketplace search bar and watch the autocomplete suggestions. These are real searches by real buyers, ranked by popularity. If you type "vintage levi" on Poshmark and see "vintage levi 501 high waist," "vintage levi trucker jacket," and "vintage levi shorts," those are the exact phrases buyers are searching for. Use them verbatim in your titles.

Do this on each platform separately. The autocomplete suggestions on eBay will be different from Depop because the buyer demographics and search behaviors are different. Cross-list the same item? You should have a different title on each platform, tailored to that platform's search patterns.

Competitor Analysis

• Search for your item type on each platform and sort by "recently sold" or "sold listings"
• Study the titles of the top-selling listings. What keywords do they include? What's the word order?
• Look at their descriptions. What information do they include that you might be missing?
• Check how many item specifics top eBay sellers fill out versus your own listings
• On Etsy, look at the tags of successful competitors using tools like eRank or Marmalead (both have free tiers)

Seasonal Keyword Rotation

Search volume shifts dramatically by season. "Summer dress" peaks in April-June. "Winter coat" peaks in September-November. "Gift for mom" spikes before Mother's Day. If you're listing seasonal items, time your keywords to match when buyers are actually searching for them. Update titles and tags to include seasonal terms during peak months, then swap them out when the season passes.

The 7 Most Common Listing Copy Mistakes

1. Using the same title on every platform. Each marketplace has different search logic and buyer behavior. Customize your titles for each.
2. Wasting title space on filler. Words like "beautiful," "gorgeous," "must-have," and "L@@K" add zero search value. Every character should be a keyword.
3. Skipping measurements. This is the number one cause of returns and buyer dissatisfaction. Include exact measurements, not just the tagged size.
4. Being vague about condition. "Good condition" means nothing. "Worn 3 times, minor pilling on cuffs, otherwise no signs of wear" tells the buyer exactly what to expect.
5. Copying your title into your tags (Etsy). Your title is already indexed. Tags should cover new ground, not repeat what the algorithm already knows.
6. Ignoring item specifics (eBay). Unfilled item specifics mean your listing gets filtered out of the searches where serious buyers shop. This is leaving money on the table.
7. Writing for yourself instead of the buyer. Your listing isn't a diary entry. It's a product page. The buyer needs to know: what is it, what size, what condition, and why they should buy it.

Platform Quick Reference

Here's a cheat sheet for the key character limits and listing features across all four platforms:

• Poshmark: 80-char title | Description sweet spot 150-300 words | Brand/size/color in title | Style tags in description | NWT/NWOT searchable
• eBay: 80-char title (aim for 75+) | Item specifics are critical for filter visibility | 500K-char description (keep it clean) | Structured data beats prose
• Depop: Combined title + description field, 1,000 chars total | 5 hashtags per listing | Aesthetic-based tags outperform generic ones | Recency matters
• Etsy: 140-char title | 13 tags at 20 chars each | Long-tail phrases in every tag | Attributes feed search filters | First 40 chars of description = preview snippet
