Your listing title is the single most important line of text in your entire reselling business. It determines whether buyers find your item in search, whether they click on it, and often whether they buy. Yet most resellers treat titles as an afterthought.

Here's the thing: each platform's search algorithm works differently. A title that ranks on eBay might flop on Poshmark. Let's break down exactly what works on each platform in 2026.

The Universal Title Formula

Across all platforms, strong titles follow this core structure:

Brand + Key Descriptor + Item Type + Size + Color/Pattern + Condition Modifier

Example: Patagonia Synchilla Snap-T Fleece Pullover Men's Large Green Vintage

But how you weight each element — and what extras you add — depends on the platform.

eBay Titles: 80 Characters of Pure SEO

eBay gives you 80 characters and uses its Cassini search engine to match listings to buyer queries. Every character matters.

The eBay Formula

Brand + Gender + Item Type + Key Feature + Size + Color + Era/Year + Condition

Examples:

Pro Tip: Don't waste eBay title characters on words like "look," "wow," "L@@K," "rare find," or "must see." These aren't search terms. Buyers search for specific attributes — pack your title with those instead.

eBay-Specific Rules

Poshmark Titles: SEO Is the New Sharing

With Poshmark's 2026 algorithm shift toward SEO-based discovery, titles carry more weight than ever. Poshmark titles have a 80-character limit.

The Poshmark Formula

Brand + Item Type + Key Style Detail + Size + Color

Examples:

Poshmark-Specific Rules

Mercari Titles: Short, Clear, Searchable

Mercari's search is less sophisticated than eBay's, but the principles are similar. Titles can be up to 40 characters — much shorter than other platforms.

The Mercari Formula

Brand + Item Type + Key Detail + Size or Color

Examples:

Mercari-Specific Rules

Depop Titles: Aesthetic Meets Search

Depop uses both the title and description for search, and the platform's audience responds to style-forward language more than other platforms.

The Depop Formula

Style/Era Tag + Brand + Item Type + Key Detail

Examples:

Common Title Mistakes (All Platforms)

  1. Being too vague — "Nice jacket size L" tells search algorithms nothing. Be specific: brand, type, material, color.
  2. Keyword stuffing — Cramming unrelated terms ("Nike Adidas Puma Jordan") to game search violates policies on every platform and can get you suspended.
  3. Ignoring the description — Titles get you found; descriptions close the sale. Pair strong titles with detailed descriptions (see our description templates).
  4. Not including measurements — Especially on eBay and Poshmark, accurate measurements in listings reduce returns and increase buyer confidence.
  5. Using abbreviations buyers don't search — "NWT" is fine (widely understood), but "VGUC" or "GUC" may confuse newer buyers. Spell it out when space allows.
