eBay SEO in 2026: How to Rank Your Listings in eBay Search

eBay SEO means getting your listings shown near the top when buyers search on eBay. eBay’s search engine is often called Cassini, and the default sort buyers see is called Best Match. eBay doesn’t publish its exact formula, but it does say which things it takes into account. This guide goes through them in eBay’s own terms and shows what to fix first on a listing that isn’t being found.

What eBay says it ranks on

eBay’s Best Match help page lists these factors:

• how closely the listing matches the buyer’s search terms
• how popular the item is
• the price of the item
• the quality of the listing: description, photos and so on
• how complete the listing is
• the listing terms, such as the return policy and handling time
• the seller’s track record

Some of these you control directly on the listing (the match to search terms, completeness, photos, price, terms). The others, popularity and your track record, follow from selling well over time. The sections below take them in the order that usually makes the most difference.

How eBay search differs from Google

Google ranks pages that answer a question; eBay ranks listings a buyer is likely to buy from. Backlinks and long text count for nothing on eBay. What counts is whether the listing matches the search, whether it is complete and competitively priced, and whether the seller delivers. A listing that matches the search but rarely sells, or comes from a seller with late deliveries and cancellations, gives eBay less reason to show it.

1. Match the words buyers search

The title is the first place eBay looks for a match. eBay’s advice is a clear, concise title with correct spelling and no more than 80 characters. In practice:

• Start with what the item is, in the words buyers use: brand, model, product type.
• Add the details buyers filter and search by: size, colour, capacity, compatible model.
• Leave out words nobody searches (“wow”, “look”, “L@@K”) and don’t repeat words.
• Don’t add brands or terms that aren’t the item. eBay’s search and listing policies treat that as keyword spamming.

To find the words, type the item into eBay’s search bar and note the suggestions, then look at the titles of similar items that have sold. Sold titles are in eBay’s free Product research tool; our guide to eBay Terapeak shows how to use it, and the eBay keyword research guide covers search suggestions and other free sources. For title structure with examples, see eBay listing titles.

2. Complete the item specifics

Item specifics such as brand, model, size, colour and style are how buyers’ filters work. If a buyer filters by size and your listing has no size, it drops out of those results, however good the title is. eBay asks for item specifics and, where the item is in eBay’s catalogue, recommends using the catalogue’s product details. Fill every field that applies to the item, and use the values eBay offers in the dropdowns where they fit, because those are the values the filters use.

3. Use honest, complete photos

Photos are part of listing quality. eBay’s tips:

• use high-quality photos taken from every angle, and show any flaws or scratches
• you can add up to 24 photos for free
• don’t add borders or text to photos
• don’t use the catalogue stock photo as the main picture if the item isn’t brand new

The main photo is also what buyers see in search results, so it decides whether they click. A clear photo of the item on a plain background usually works better than a busy scene.

4. Price and postage against what sells

Price is one of eBay’s listed factors, and eBay’s first tip is to offer competitive prices and reasonable postage. Compare your total price, item plus postage, with what similar items have actually sold for, not with other sellers’ asking prices. Sold prices are in Product research (see the Terapeak guide). Before you cut a price to compete, check what is left after fees with the eBay profit calculator.

5. Set clear listing terms

eBay names the return policy and handling time among its ranking factors. State the postage cost, handling time and return policy on every listing, and say clearly if anything is different for international buyers. A shorter handling time and a return policy buyers are comfortable with make the listing more attractive to buyers and to search.

6. Protect your seller track record

Your track record applies to every listing you have, so a problem here holds back the whole account. eBay’s advice is to get items to buyers on time with tracking, describe items accurately, and keep stock levels accurate so you don’t have to cancel sales. These are also the measures in eBay’s seller performance standards: transaction defects (including cancellations for being out of stock), late shipments and cases closed without seller resolution.

Check the Performance tab in Seller Hub every week. If your level has dropped, our guides to eBay defects explain what can be fixed or appealed.

7. Pick the right category and avoid duplicates

List each item in the category that fits it best, since buyers browse and filter by category. Don’t list the same item more than once as separate fixed-price listings to take up more of the results: eBay’s duplicate listings policy doesn’t allow it. For several of the same item, use one listing with a quantity, or one listing with variations for sizes and colours.

Promoted Listings and search

Promoted Listings are eBay ads. eBay says promoted listings that match a buyer’s search can appear higher in search results, and you pay only under the terms of the campaign you choose. They can help a new listing get seen, but they don’t fix a listing that is incomplete or overpriced. Our post are eBay Promoted Listings worth it? shows how to work out whether the ad rate pays for itself.

Where AI tools help

AI writing tools can save time on descriptions and title drafts, especially across many listings. Treat what they produce as a draft: check every fact against the item, keep the words buyers actually search, and make sure the item specifics are filled in eBay’s own fields rather than only in the description. A tool that guesses a model number or a material can lead to returns and “not as described” cases, which hurt the track record that search relies on.

A checklist for a listing that isn’t found

Check	What to look at
Title	Brand, model and product type first, in buyers’ words; 80 characters or fewer; no unrelated terms
Item specifics	Every field that applies is filled, using eBay’s values
Category	The most specific category that fits the item
Photos	Several clear photos from every angle, flaws shown, no borders or text
Price	Item plus postage compared with recent sold prices, not asking prices
Terms	Handling time, postage and return policy stated
Seller performance	No recent late shipments, cancellations or open cases you can still fix
Duplicates	One listing per item, using quantity or variations

Change one thing at a time and give it a few weeks before judging, so you can tell what made the difference. Seller Hub’s traffic report shows impressions and click-through for each listing; our guide to eBay listing visibility explains how to read it.

Frequently asked questions

What is the most important eBay ranking factor?

eBay doesn’t publish weights. It lists the match to the search terms, popularity, price, listing quality, completeness, listing terms and the seller’s track record. A listing has to match the search to appear at all, so the title and item specifics come first.

What is Cassini?

Cassini is the name commonly used for eBay’s search engine. The order buyers see by default is Best Match, and eBay’s Best Match help page is the official description of what it takes into account.

Do I need an eBay Store for eBay SEO?

No. Titles, item specifics, photos, pricing, terms and seller performance work the same with or without a Store. eBay’s Product research tool (formerly Terapeak) is free in Seller Hub; only Sourcing insights needs a Basic Store or higher.

How long does an eBay title have to be?

Up to 80 characters. Use the space for words buyers search and details that tell your item apart, not filler.

Do Promoted Listings help organic ranking?

eBay says promoted listings that match a search can appear higher in results; that placement is paid. eBay doesn’t say that promoting a listing raises its unpaid position, so judge a campaign on the sales it brings at the ad rate you pay.
