eBay Keyword Monitoring: How AND/OR Logic Changes What You Find

When you set up an eBay alert, you type in a keyword and hope for the best. If you search for "Jordan 1", you miss every listing that only says "Jordan retro" or "AJ1". If you search for "PSA 10", you miss everything graded by BGS. You end up creating five separate alerts for variations of the same thing.

There's a better way — and understanding it will change how you set up every deal search going forward.

The Problem With Single-Keyword Alerts

eBay sellers are inconsistent. Two sellers listing the exact same item will write completely different titles. One writes "Air Jordan 1 Chicago OG". Another writes "AJ1 Chicago 2015 size 10". A third writes "Jordan retro 1 og chicago red black".

A single-keyword alert for "Air Jordan 1" catches the first listing. It misses the other two entirely. Those two listings are just as real — and if they're underpriced, someone else is buying them while your alert sits silent.

The same problem applies in every category: sports cards, vintage electronics, collectibles, tools. Sellers write titles differently, abbreviate differently, and describe the same item ten different ways.

What OR Logic Does

OR logic lets you monitor multiple keyword variations in a single search. Instead of creating three separate alerts, you write one search that fires when any of your terms match.

Examples of OR logic in practice:

• "Jordan 1 OR AJ1 OR Air Jordan retro 1" — catches listings using any of those phrasings
• "PSA 10 rookie OR BGS 9.5 rookie OR SGC 10 rookie" — covers multiple grading companies in one search
• "Gameboy OR Game Boy OR GBA OR Game Boy Advance" — catches every common way sellers describe the same handheld
• "Levi OR Levis OR Levi's 501 OR Levi 501 vintage" — handles apostrophe variations and spacing differences

One search replaces three to five separate alerts. Fewer alerts to manage, and better coverage of what you're actually looking for.

What AND Logic Does

AND logic requires every term in the search to appear in the listing title. It narrows results rather than expanding them.

AND is useful when you need to be specific to avoid noise. If you're monitoring for vintage Rolex watches, you don't want every listing that just mentions "Rolex" — that's thousands of results including straps, cases, and replicas. "Rolex AND Submariner AND vintage" narrows it down to listings that include all three terms.

• "Funko Pop AND graded AND 9.5" — only graded Funkos with a specific score, not all Funkos
• "MacBook Pro AND M2 AND 16GB" — filters to the specific configuration, not every MacBook listing
• "Pokemon AND sealed AND booster AND first edition" — cuts through thousands of Pokemon listings to find what you actually want

Combining AND and OR in One Search

The most powerful searches combine both. For example:

"(Jordan 1 OR AJ1 OR Air Jordan retro 1) AND (size 10 OR sz 10 OR 10.0)" — monitors for Jordan 1s in size 10 across all the different ways sellers write both the shoe name and the size.

This kind of search is impractical to replicate with eBay's native saved searches. You'd need a separate saved search for every combination of shoe name and size variation — dozens of alerts for a single target item.

Practical Keyword Strategies by Category

Sports Cards

• Cover grading company variations: PSA, BGS, SGC, CSG — sellers abbreviate inconsistently
• Include both "rookie" and "RC" — both appear frequently in titles
• Include the player's full name and common abbreviations or nicknames

Sneakers

• Include model number, brand name variation, and common shorthand (Jordan 4, AJ4, Air Jordan 4 retro)
• For high-value colorways, include colorway name AND the model — avoids alerts for cheap colorways of the same model
• Add size to AND logic if you only want your size — otherwise you'll get alerted for every size

Vintage Electronics

• Always include model number variations — sellers type model numbers inconsistently
• Include both spelled-out and abbreviated versions (Macintosh OR Mac, Nintendo OR Nintendo Entertainment System OR NES)
• Consider adding "working" to AND logic if condition matters — cuts out listings of broken units for parts

Setting It Up in Deal Scout 360

Deal Scout 360 supports AND/OR keyword logic directly in the search field. You write your keywords using OR to separate alternatives and AND to require terms — the same syntax used in the examples above.

Combine keyword logic with the shipping-aware price filter and you have a search that's covering more listing variations while still only alerting you when the total cost fits your budget. That combination is what makes the monitoring actually useful for resellers versus casual browsing.
