Your listing title is the single most important piece of text you write as a reseller. It determines whether your item shows up in search results, whether a buyer clicks on it, and on some platforms, whether the algorithm even surfaces it to potential buyers. A great photo gets the sale — but the title gets the click.

The problem is that every platform's search algorithm works differently. What ranks on eBay can actually hurt you on Depop. What works on Poshmark is irrelevant on Facebook Marketplace. Here's how to write titles that get found — and clicked — on every major reselling platform in 2026.

eBay: The Cassini Search Engine

eBay's search engine (Cassini) is the most sophisticated in the reselling world. It analyzes your title, item specifics, listing quality, seller metrics, and buyer behavior to rank listings. Here's the formula that works:

The 80-Character Rule

eBay gives you 80 characters. Use them all. Every word is a potential search match. But — and this is critical — front-load the most important keywords. Cassini gives more weight to the first words in your title.

Good: Vintage Polo Ralph Lauren Cable Knit Sweater Men's XL Navy Blue Crew Neck
Bad: Great Sweater! Perfect for Winter — Ralph Lauren Blue XL Mens Vintage

The good title leads with "Vintage Polo Ralph Lauren" — the exact phrase a buyer types when searching. The bad title leads with filler words that no one searches for.

What to Include (In This Order)

  1. Brand name — always first or second word
  2. Product type — "Cable Knit Sweater" not just "Sweater"
  3. Gender/size — "Men's XL" or "Women's Size 8"
  4. Color/pattern — "Navy Blue" or "Plaid"
  5. Key descriptors — "Vintage," "NWT," "Rare"
  6. Style details — "Crew Neck," "Slim Fit," "High Rise"

What to Never Include

Pro Tip: Use eBay's search bar to research titles. Start typing your item's brand + category and watch the auto-suggest dropdown. Those suggestions are the most-searched phrases on the platform. Build your title around them.

Poshmark: The Social Discovery Algorithm

Poshmark's search has evolved significantly. While it still emphasizes sharing and community engagement, the platform has been investing in search functionality and recently rolled out improved keyword matching.

Key Differences from eBay

Good: Lululemon Align High-Rise Leggings 25" Black Size 6
Bad: Amazing Workout Leggings! Black Athletic Pants Yoga Gym Size Small

Depop: Hashtag-Driven Discovery

Depop's search relies heavily on keywords and hashtags within your description, but the title is still what buyers see first in search results. The platform's Gen-Z audience searches differently than eBay or Poshmark buyers.

What Works on Depop

Good: Vintage Y2K Nike Track Jacket Windbreaker Size M
Bad: Nike Jacket Medium Used Condition Athletic Wear

The "Y2K" and "Vintage" keywords in the good title tap into how Depop buyers actually search. They're looking for aesthetics, not just products.

Facebook Marketplace: Local Search Optimization

Facebook Marketplace search is the most basic of the major platforms, but it reaches the largest audience. The algorithm prioritizes location, price, and exact keyword matches.

Facebook-Specific Title Tips

The Universal Title Formula

Across every platform, this structure consistently performs:

[Brand] [Product Type] [Key Feature] [Size/Color] [Condition]

Examples:

This formula works because it mirrors how buyers search: they know the brand, they know what they want, and they're filtering by size and color. Give them that information in exactly that order.

Common Title Mistakes That Kill Sales

MistakeWhy It HurtsFix
Leading with adjectivesNo one searches "Beautiful Gorgeous"Lead with brand name
Using abbreviations"RL" doesn't rank for "Ralph Lauren"Spell out brand names
Keyword stuffingPlatforms penalize irrelevant termsOnly include accurate descriptors
Too vague"Nice shirt" matches nothing specificBe specific: brand, type, size, color
Copy-pasting across platformsEach algorithm weights differentlyCustomize per platform (or use cross-listing tools that adapt)

Titles are the unsexy part of reselling. Nobody gets excited about writing 80 characters of product description. But the difference between a well-optimized title and a lazy one can be the difference between an item selling in 3 days or sitting for 3 months. Pair strong titles with compelling descriptions and sharp product photos, and your listings will work harder for you than ever.
