How eBay’s Cassini Search Engine Ranks Your Listings

eBay doesn’t use Google’s algorithm. It uses its own search engine called Cassini, and understanding how it works is the foundation of any eBay SEO strategy.

Cassini’s primary goal is to match buyers with the most relevant listings that are most likely to result in a completed sale. It evaluates several factors:

• Relevance, How well your title, description, and item specifics match a buyer’s search query.
• Listing quality, Complete, accurate, and well-structured listings score higher.
• Seller performance, Your track record matters. Metrics like defect rate, on-time shipping, and feedback scores feed directly into rankings.
• Engagement signals, Click-through rate, watch counts, and sales velocity all tell Cassini that buyers find your listing valuable.

The takeaway? Cassini rewards sellers who make the buying experience easy and trustworthy. Every optimisation decision you make should keep this in mind.

Keyword Research Strategies for eBay Sellers

Keywords are the bridge between what buyers search for and what you’re selling. Get them right, and your listings appear in front of the right people.

Start with eBay’s own search bar. Type in your product and look at the autocomplete suggestions, these reflect real buyer searches. It’s one of the simplest and most effective research methods available.

Beyond that, consider these approaches:

• Analyze top-performing competitors. Look at what high-ranking sellers in your category use in their titles and descriptions.
• Use keyword tools. Tools like Terapeak (built into Seller Hub) give you data on search demand and sell-through rates for specific terms.
• Think like a buyer. Include brand names, model numbers, sizes, colors, and condition. Buyers search with specifics.

Avoid stuffing irrelevant keywords into your listings. Cassini penalizes this. Focus on accuracy and intent, the terms buyers actually use when they’re ready to purchase.

Optimizing Titles, Descriptions, and Item Specifics

Your title is the single most important ranking factor on eBay. You’ve got 80 characters, use them wisely.

Here’s what works:

• Front-load your primary keyword. Put the most important search term at the beginning of the title.
• Include key attributes. Brand, size, color, material, model number, these help Cassini match your listing to specific queries.
• Skip filler words. Words like “amazing,” “wow,” or “L@@K” waste character space and don’t help with search.

For descriptions, write clear and informative copy that answers buyer questions upfront. What’s included? What condition is it in? What are the dimensions? Structured HTML with bullet points performs better than walls of text.

Item specifics are non-negotiable. eBay uses them to filter search results, and listings without complete item specifics get buried. Fill in every relevant field, even the optional ones. It’s one of the easiest wins in eBay product listing and store optimization.

Seller Performance Metrics That Impact Your Visibility

You can have the most perfectly optimized listing on eBay, and it still won’t rank if your seller metrics are poor. Cassini weighs your performance heavily.

Key metrics that affect visibility:

• Defect rate, Transactions with issues (cases closed without resolution, late shipments, etc.) drag your rankings down.
• On-time shipping and tracking, Uploading tracking numbers and shipping within your stated handling time signals reliability.
• Feedback score and percentage, Consistent positive feedback builds trust with both Cassini and buyers.
• Return rate, High return rates can indicate inaccurate listings, which Cassini doesn’t favour.

Aiming for Top Rated Seller status isn’t just a badge, it directly impacts your search placement. Top Rated Sellers get a ranking boost, better visibility in Best Match results, and access to discounted fees.

The bottom line: treat seller metrics as part of your SEO strategy, not separate from it.

Advanced eBay SEO Tactics: Images, Pricing, and Promotions

Once your fundamentals are solid, these advanced tactics can push your listings further up the results.

Images That Convert

Use high-quality photos with a white background for your main image. Include multiple angles, close-ups of details, and lifestyle shots where relevant. eBay’s algorithm considers image quality, and buyers are far more likely to click on clean, professional photos.

Competitive Pricing

Cassini factors in price competitiveness. That doesn’t mean you need to be the cheapest, but your pricing should be reasonable relative to similar listings. Offering free shipping can also improve your ranking, as eBay tends to favour listings with free postage in search results.

Promoted Listings and Sales Events

eBay’s Promoted Listings program increases visibility by placing your items in prominent positions. Combine this with markdown sales or volume pricing to boost conversion rates. Higher conversions signal to Cassini that your listing deserves more organic visibility too.

These tactics work best when layered on top of strong keyword targeting and solid seller metrics.

Common eBay SEO Mistakes to Avoid

Even experienced sellers make mistakes that hurt their rankings. Here are the most common ones we see:

• Keyword stuffing, Cramming unrelated or duplicate keywords into titles confuses Cassini and turns buyers off.
• Incomplete item specifics, Leaving fields blank means your listing won’t appear in filtered searches.
• Poor-quality images, Blurry, cluttered, or watermarked photos reduce click-through rates.
• Ignoring mobile, Over 60% of eBay transactions involve mobile. If your descriptions rely on heavy HTML that doesn’t render well on phones, you’re losing sales.
• Inconsistent shipping and handling, Late shipments and missing tracking hurt your seller score, which directly impacts ranking.

Avoiding these mistakes doesn’t require a massive overhaul. It requires consistency and attention to detail.
