eBay Keywords in 2026: What Best Match Actually Reads
Most eBay keywords advice is guesswork about a secret algorithm. It does not need to be. eBay publishes the factors its search uses, and there are seven of them. Four are things you control when you write a listing title.
This guide works through each published factor and what it means for the words you choose. Every claim below comes from eBay's own optimization guidance, verified on 13 August 2026.

The seven factors eBay names
eBay describes its search as running "on the principle of Best Match", and names Cassini as the internal search engine behind it. The two words describe one system, so treat them as interchangeable.
eBay lists seven things Best Match considers:
| # | Factor eBay names | Do keywords affect it |
|---|---|---|
| 1 | How closely the listing matches the buyer's search terms | Directly |
| 2 | How popular the item is | No |
| 3 | The price of the item | No |
| 4 | The quality of your listing, description, photos and so on | Partly |
| 5 | How complete the listing is | Directly |
| 6 | Listing terms of service, return policy and handling time | No |
| 7 | Your track record as a seller | No |
Only factor 1 is what most people mean by keywords. Factor 5, completeness, is the one almost every guide skips, and it is where item specifics live.
That distribution matters. Four of the seven factors have nothing to do with wording at all. If you are rewriting titles every week and your handling time is five days, you are optimising the smallest lever you have. You can run your own numbers as you read to see how the other side of the equation behaves.
Your title has 80 characters
eBay sets the title limit at 80 characters and publishes a recommended order: [NEW] [brand] [product name] [model No] [Variants].
That order is not decoration. It front-loads the terms a buyer types first. Someone searching for a part types the brand and model number, rarely an adjective. Condition, brand, product, model, then variant detail is the sequence that matches how the query arrives.
Eighty characters is roughly twelve words. That budget forces a decision on every term. Because Best Match scores how closely your listing matches the buyer's search terms, a word that does not describe your item does not widen your reach. It dilutes the match on the words that do.
Three habits waste the budget:
- Filler words. "Look", "wow", "rare", "L@@K". None of these are search terms.
- Repeated terms. The same word twice does not double anything.
- Unrelated brands. Naming a brand you are not selling is a match on a query you cannot satisfy.
If you sell the same item across markets, the title budget is per listing, not per account. A UK listing and a US listing can carry different terms, because buyers in each market search differently.
Abbreviations deserve their own note. Seller shorthand like EUC or NWT reads as a keyword to you and as noise to Best Match if buyers do not search it. We covered one of these in detail in what EUC means on eBay, including why eBay itself never uses the term.
Item specifics are keywords too
eBay states that "complete and accurate item specifics are likely to increase the visibility of your listing in eBay search results."
This is factor 5, completeness, and it is the highest-value place to put keywords that will not fit in 80 characters. Item specifics are structured fields, so brand, model, size, colour and material go there as data rather than prose. A buyer who filters by brand in the sidebar is reading item specifics, not your title.
The practical rule follows from the wording eBay uses. Complete matters, and accurate matters. Filling a field with a value that does not describe the item is not a shortcut into more searches. It is an inaccurate specific, and the same completeness factor that rewards a full listing is the one reading it.

Shipping and handling time change placement
Two of eBay's statements here are concrete enough to act on.
On handling time, eBay states that shorter handling times produce earlier estimated delivery dates for the buyer, and that "your listings will get preference over competitors in the search results." Handling time is a setting, not a word. It moves placement without touching your title.
On shipping cost, eBay states that "more than 80% of customers look for products with free shipping." That is buyer behaviour rather than a ranking factor, but it lands on the same outcome. A listing buyers filter out never gets the click that popularity, factor 2, is built from.
Free shipping is not free. The cost moves into your item price, which moves your final value fee, because the fee base includes shipping. That interaction is worth checking before you switch a listing over, and it is set out in full in our guide to eBay fees.
Seller performance sits underneath everything
eBay states that "seller performance greatly affects the position of your listings in eBay search results", and separately lists "your track record as a seller" as factor 7.
No keyword compensates for this. A seller below standard is carrying a placement penalty on every listing at once, which no title rewrite reaches.
The sequence this implies is unglamorous. Fix handling time, fix performance, complete your item specifics, then spend time on wording. Most guides invert that order because wording is the part that feels like strategy.

More views only matter if the margin survives
Keyword work raises impressions. It does nothing to what you keep from a sale.
A listing that reaches twice as many buyers at a price that loses money simply loses money faster. Before you rewrite a catalogue of titles, it is worth knowing the fee floor on the items you are rewriting, because that number decides whether extra visibility is worth having.
eBay's research tools sit inside the same account you are already using. We covered what is free and what is not in Terapeak in 2026, which is the starting point before paying for a third-party keyword tool.
Conclusion
Four things carry most of the weight.
- eBay publishes seven Best Match factors. Only one of them is about matching search terms, and a second is about listing completeness.
- The title limit is 80 characters, and eBay's own recommended order is
[NEW] [brand] [product name] [model No] [Variants]. - Item specifics are the overflow space for keywords that do not fit, and eBay states they are likely to increase visibility.
- Handling time and seller performance move placement without any wording change at all.
Write the title for the query, fill the specifics completely, then check what the sale actually pays you.
