eBay’s Cassini 2.0 update introduced AI-powered item specifics matching that buries listings with incomplete or vague product data, even if your title is perfect.
Search is changing faster than most marketers realize. What worked six months ago to get traffic is already outdated. Here is what you need to know about ebay cassini 2.0 is here: why your listings are suddenly invisible, broken down into the questions real business owners are asking.
What changed in eBay’s Cassini 2.0 search update?
Cassini 2.0 replaces eBay’s traditional keyword-matching engine with an AI system that evaluates listing completeness, structured data accuracy, and semantic relevance. The AI scores every listing on a 0-100 quality scale. Listings below 50 get almost zero organic visibility regardless of title keywords. The update rolled out globally in March 2026.
Why are item specifics suddenly critical for eBay visibility?
Cassini 2.0 uses item specifics as its primary relevance signal. Each filled specific is a data point in eBay’s knowledge graph. Listings with 80%+ item specifics filled rank 3x higher than those with 50% or fewer. The AI cross-references specifics against category norms — a laptop listed as ‘Used’ without specifying RAM, storage, and processor generation is effectively invisible.
How does AI-powered category matching work on eBay?
eBay’s AI now automatically suggests or reassigns categories based on listing content. If your listing is in the wrong category, the AI either moves it (hurting your performance history) or buries it. Use eBay’s Category Recommendations tool before listing. The AI also cross-matches similar categories — a camera in ‘Photography’ also appears in ‘Electronics’ searches if structured correctly.
What role does structured data play in Cassini 2.0?
Structured data is the foundation. eBay’s AI extracts product attributes from item specifics, not descriptions. The ‘Item Specifics’ section is now the most important part of any listing. eBay provides category-specific templates — use them. Custom specifics for unique attributes (like ‘Paint Type’ for art supplies) are supported and encouraged.
How does listing completeness scoring work?
eBay calculates a listing completeness score based on: item specifics filled (40% weight), image count and quality (25%), description detail (20%), pricing competitiveness (10%), and shipping options (5%). Scores update every 24 hours. Listings below 60 get an automated ‘Complete Your Listing’ prompt. Ignore it and your visibility drops further.
How do eBay Promoted Listings interact with AI search?
Promoted Listings now include an AI optimization layer that suggests bid adjustments based on listing quality scores. High-quality listings get 30% lower cost-per-click for the same ad placement. eBay’s AI also recommends which listings to promote — ignoring its suggestions leaves money on the table.
Does international eBay searching use different AI models?
Different eBay markets use localized AI models trained on regional shopping patterns. German eBay (eBay.de) AI prioritizes detailed specifications and warranty information. UK eBay emphasizes condition descriptions. US eBay focuses on brand and model. Sellers on multiple markets should customize listings per region.
How can I optimize my eBay storefront for AI search?
Create structured store categories that mirror your product taxonomy. Use store features (about pages, sale events, item filters) — the AI evaluates store quality as a listing signal. Cross-promote related items within your store. eBay’s AI favors stores with clear organization and complete inventory information across all listings.
