Audience: Sellers learning eBay SEO basics
Direct answer
Cassini is the common seller name for eBay's search and Best Match ranking system. eBay does not publish a simple ranking formula, but sellers can influence visibility through relevant titles, accurate item specifics, competitive pricing, strong photos, seller performance, and listing quality. Listowise focuses on the parts sellers can improve during listing creation: title wording, item specifics, description quality, and publish readiness.
Practical ranking inputs sellers can control
Use clear product keywords in the title, complete item specifics, accurate condition details, competitive price, and strong images.
Avoid keyword stuffing and unsupported claims. Relevance matters more than cramming every possible word into the title.
