Understanding How eBay Cassini Evaluates Product Listings
eBay’s search engine, Cassini, is designed around a single core objective: connecting shoppers with the exact items they wish to purchase while rewarding trustworthy sellers who provide frictionless buying experiences.
Unlike standard text-based web search engines, Cassini heavily weights sales conversion velocity, item specifics completeness, and defect-free listing health. At FlexShop Ltd, our listing optimization methodology consistently yields double-digit visibility gains across complex catalogs.
1. Algorithmic Title Structure & Keyword Priority
The 80-character eBay title is the single most valuable SEO real estate in your listing. Cassini reads titles left-to-right, granting maximum algorithmic weight to the opening 35 characters.
- Optimal Structure: [Brand] + [Exact Product Model/MPN] + [Key Defining Feature/Size] + [Primary Use Case] + [Color/Material].
- Avoid Keyword Stuffing: Punctuation marks (like exclamation points or quotation marks) and generic fluff words (“L@@K”, “WOW”, “HOT”) degrade your Cassini trust score and waste precious characters.
2. 100% Item Specifics Coverage (The Secret to Filter Ranking)
Over 62% of eBay purchases originate through faceted category filters on mobile devices. If an item specific is left blank in your backend feed, your listing is completely hidden the instant a shopper taps that filter attribute.
Ensure you populate all required, recommended, and additional attributes, including GTIN, UPC, EAN, MPN, Material, Country of Manufacture, and Compatible Vehicle Fitment.
3. Modern Active Content-Free HTML Templates
eBay strictly prohibits active content (JavaScript, Flash, external iframes, or non-HTTPS assets). All templates engineered by FlexShop Ltd utilize pure CSS flexbox and grid layouts that render crisply across mobile viewports, reducing bounce rates and accelerating conversions.
