eBay Algorithm 2025 | How to boost sales

eBay’s search algorithm—often referred to as Cassini—is designed to connect buyers with the most relevant listings. It ranks and displays listings based on a combination of factors, aiming to maximize conversion rates.

Here are the key areas the algorithm assesses when determining which listings to show customers:

1. Relevance to Search Query

- Title keywords are matched against the user's query.

- eBay prioritizes exact matches and relevant synonyms.

- Item specifics (brand, size, color, etc.) also influence relevance.

2. Listing Quality

- High-quality titles (concise, keyword-rich).

- Item specifics filled out thoroughly.

- High-resolution photos and detailed descriptions.

Use of structured data and correct categories.

3. Seller Performance

- Seller ratings (positive feedback, low defect rates).

- On-time shipping performance.

- Customer service history (returns, cancellations, disputes).

4. Buyer Behavior Signals

- Click-through rate (CTR).

- Time spent on listing page.

- Add-to-watchlist and add-to-cart activity.

- Conversion rate (how often views lead to sales).

5. Price & Shipping

- Competitive pricing.

- Free shipping can boost visibility.

- Total cost to the buyer (item + shipping) is considered.

6. Recent Sales Velocity

- Listings that have sold recently or frequently often get a boost in search results.

Making small improvements in these areas will make a dramatic difference to your business. If you would like help improving your eBay listings to improve conversion rates then get in touch.
