Rank in eBay's Cassini Search - Where Buyers Actually Find You.
eBay’s Cassini algorithm rewards relevance, listing quality, and seller performance very differently from Google or Amazon. Generic listings sink. We optimize specifically for Cassini so your products surface.
Cassini Plays by Its Own Rules - and Buries Listings That Ignore Them.
eBay’s search engine, Cassini, weighs relevance, item specifics, sell-through, and seller performance. Home improvement sellers who copy listings from other channels miss the item specifics and structure Cassini needs – so they never rank, no matter how good the product.
We optimize for Cassini’s actual ranking factors: complete item specifics, keyword-aligned titles, listing quality, and the performance signals that lift placement.
- Your listings don't appear for your main eBay search terms.
- Low sell-through is dragging your rank down.
- Item specifics are incomplete or missing.
- You're treating eBay like a copy of another marketplace.
- Titles aren't aligned to how eBay buyers search.

Let's have Your Questions Answered
01What is Cassini?
Cassini is eBay’s search engine. It ranks listings on relevance, item specifics, sell-through, price, and seller performance – so eBay SEO is its own discipline, distinct from Google or Amazon.
02Why do item specifics matter so much?
Cassini uses them to match listings to searches and filters. Incomplete specifics mean your products simply don’t surface for relevant queries.
03Can low sell-through hurt my rank?
Yes. Cassini rewards listings that sell. We optimize price, content, and promotion to lift sell-through, which then lifts rank.
04Can you optimize my whole eBay store?
Yes. We prioritize your best-opportunity listings first, then work through the catalog systematically.
