If you bought something great and want more of it, or you're sizing up a rival store, knowing how to find a seller on eBay is a small skill that pays off constantly. eBay hosts millions of active sellers, and the platform tucks seller search away in a few different places depending on the device you're using. This guide walks through every reliable method, then shows the move most shoppers miss: using seller search as the starting point for real product research.
Quick answer: The fastest way to find a seller on eBay is Advanced Search → scroll to the Sellers section → enter their username under "Only show items from" → Search. If you already know the exact username, going straight to ebay.com/usr/username is even quicker.
- Know the username? Type
ebay.com/usr/usernameinto your browser to land on their profile instantly. - Don't know it exactly? Use Advanced Search's Sellers filter, or the
seller:usernameoperator in the search bar. - On the app? Open any of their listings and tap the seller's name — the app has no standalone seller-search box.
- Researching competitors? Finding the store is step one; finding what's actually selling inside it is where the money is.
How to Find a Seller on eBay With Advanced Search
Advanced Search is eBay's most flexible tool for this, and it still works when you know only part of the seller's username. Here's the exact sequence on desktop:
- Click Advanced next to the main search bar at the top of any eBay page (or go directly to
ebay.com/sch/ebayadvsearch). - Scroll down to the Sellers section.
- In the "Only show items from" dropdown, choose Specific sellers and type the username into the box.
- Optionally add a keyword up top — for example, type "camera" plus the username to see only that seller's camera listings.
- Click Search. You'll get every active listing from that seller, which you can then sort by price, newest, or best match.
One thing Advanced Search does well that the basic bar can't: you can combine a seller with filters like condition, price range, item location, and "Sold listings." That last filter is the one serious sellers care about, and we'll come back to it, because sold listings are the difference between admiring a store and understanding it. If you've ever wondered how the platform decides which listings to surface first, our breakdown of eBay's Cassini search engine explains the ranking signals at play.
Ecomli is an AI-powered dropshipping automation platform built for eBay sellers, and it turns this kind of seller research into ready-to-list products with suppliers already attached. Before going further, it helps to know what you're actually shopping for when you study other stores. A clear eBay product research method turns "this store looks busy" into a list of specific products worth listing yourself — and it's the foundation everything below builds on. Sellers who skip this step tend to copy whole catalogs instead of the handful of items that actually move.
6 More Ways to Find an eBay Seller
Advanced Search is the workhorse, but it isn't always the quickest route. Depending on what you already know about the seller, one of these will be faster:
| Method | How it works | Best for |
|---|---|---|
| Direct store URL | Type ebay.com/usr/username or ebay.com/str/storename | You know the exact username or store name |
| All-items URL | Visit ebay.com/sch/username/m.html | Seeing a seller's complete active catalog on one page |
seller: operator | Type seller:username keyword in the search bar | Quick filtered searches without leaving the homepage |
| From a listing | Click the seller's name on any listing, then "See other items" | You found one product and want the rest of the store |
| By name / partial | Google site:ebay.com "store name" | You remember the store name but not the username |
| Feedback profile | Click a feedback score to view the member profile | Vetting a seller's history before buying or copying |
The seller:username operator is underused and genuinely fast: typing seller:techbargains laptop instantly narrows results to one store. It's the kind of shortcut that saves a few seconds hundreds of times a week once you're researching stores seriously. If you're trying to find a seller by a half-remembered name, the Google site: trick beats clicking around eBay — eBay's own search rewards exact usernames, while Google indexes store names and descriptions.
Whichever route you take, it's worth a glance at the seller's feedback profile before you act on what you see. Click the feedback score next to their name to open the member profile, then check the feedback percentage, how long they've been registered, and the detailed seller ratings for shipping and item-as-described. A store with thousands of recent positive transactions is telling you something different from one with twenty — and if you're studying that store as a competitor, those numbers are a rough proxy for how much volume the catalog actually moves. The recent sold-through on individual listings fills in the rest.
Tools built for this kind of work go a step further. Ecomli — an AI-powered dropshipping automation platform for eBay sellers — treats competitor stores as a data source rather than a curiosity, which is the mindset shift that separates browsing from research. We'll get into exactly how shortly. If you're comparing the broader category of research tools, our roundup of Terapeak alternatives for seller research covers what each one does and doesn't surface.
How to Find a Seller on eBay Using the Mobile App
This is where most people get stuck, because the eBay app deliberately has no dedicated "search by seller" box the way desktop does. If you've ever felt like seller search vanished, you're not imagining it — the mobile flow is genuinely different. Here's what works:
- From a listing: Open any item from the seller, scroll to the seller information, and tap their username. That opens their store, where you can browse or search within their items.
- Direct URL: The
ebay.com/usr/usernameandebay.com/str/storenamelinks work in the app's browser and in mobile Safari or Chrome, dropping you straight onto the profile. - Save the store: Once you're on a seller's page, tap "Save this seller" so you can jump back without searching again — useful when you're tracking a handful of competitors over time.
The takeaway: on mobile, you reach a seller through their products, not through a search box. That's a small annoyance for shoppers and a real friction point for sellers doing research on the move, since you can only study one store at a time and nothing is saved in a structured way. It's one reason most people who research competitors seriously end up doing it on desktop or inside a dedicated tool.
From Finding Sellers to Finding Winners: Competitor Research
Here's the part the standard guides skip. For a shopper, finding a seller is the finish line. For anyone who sells — or wants to — it's the starting line. The store itself isn't the prize; the prize is knowing which specific items in that store are actually selling, and where to source them.
You can do a surprising amount manually. Find a high-performing seller with Advanced Search, then switch on the Sold listings filter to see what genuinely moved rather than what's merely listed. Sort by most recent sold, note the items appearing again and again, and you've got a shortlist of proven demand. The problem is what comes next: for every winning product, you still have to find a supplier, match the exact item, check the cost, and work out whether the margin survives eBay's fees. Doing that by hand across dozens of products is where the hours disappear — it's the single biggest reason product research stalls before it produces a single new listing. This is exactly the gap Ecomli closes: its Smart Scraper clones a competitor's proven sellers with a matched supplier already attached, so the supplier hunt and margin math are handled automatically instead of by hand.
This is the exact problem Ecomli's Smart Scraper was built to remove. Instead of eyeballing a competitor's store one listing at a time, you point Ecomli at an eBay seller and it pulls their verified winning products — items that have already sold — with a matched supplier from Amazon or AliExpress attached, ready to import in a few clicks. You're not guessing what might sell; you're starting from products the market already proved, with the supply chain wired in. The same Smart Scraper can sweep entire Amazon and AliExpress stores into thousands of import-ready products in minutes, so the research-to-listing gap that normally eats an afternoon collapses into a short session.
That's a different proposition from a classic eBay listing scraper that just dumps titles and prices. Matching each winner to a real, in-stock supplier is the step that actually lets you list, and it's what turns competitor research into inventory. If you've leaned on AutoDS alternatives before, this is the capability worth comparing them on.
Turn Competitor Sellers Into Live Listings
Finding winners is only valuable if you can act on them without drowning in manual work. Once Ecomli has pulled a competitor's proven products with suppliers attached, the rest of the loop is designed to run with very little hands-on time — which is what makes studying competitor stores worth doing at scale instead of as a one-off.
Three Ecomli capabilities carry that load. Constant stock and price monitoring watches every supplier around the clock, so if a supplier's price jumps or an item goes out of stock, your listing reprices or pauses automatically — you never sell something you can't fulfill or sell below your margin floor. (If repricing is your main concern, our guide on repricing to defend margin goes deeper.) Auto-ordering places the supplier order the moment a sale comes in, so fulfillment doesn't pull you back into manual purchasing. And multi-channel support means the winners you find don't have to live only on eBay — you can list across Amazon and Etsy too, so a single store's research compounds across platforms.
The practical effect is that "find a seller" stops being a dead end and becomes a repeatable input. You study a strong competitor on the Seller Hub, scrape their proven products into Ecomli, and the platform handles sourcing, listing, monitoring, and ordering from there. As your catalog grows, you can keep feeding it new competitor stores — just remember to raise your selling limits in step so your account can hold everything you list. You can start a free trial to run the workflow on a real competitor store, or compare what each tier includes on the pricing page.
Frequently Asked Questions
Can you search for a seller on eBay by name?
Yes, but it works best with the exact username. On desktop, use Advanced Search's Sellers filter and enter the username, or type ebay.com/usr/username directly. If you only remember a store name rather than the username, a Google search for site:ebay.com "store name" is usually the fastest way to surface the right profile.
How do I find a specific seller on eBay when I know what they sell?
Combine the two in Advanced Search: enter a product keyword at the top and the seller's username in the Sellers section. eBay returns only that seller's listings matching your keyword. The seller:username keyword operator does the same thing straight from the search bar without opening Advanced Search.
How do I find a seller on the eBay app?
The app has no standalone seller-search box. Open any listing from that seller, tap their username to reach their store, then browse or search within their items. The ebay.com/usr/username URL also works in the app's browser and will take you straight to the profile.
Why can't I find a seller on eBay the way I used to?
eBay has gradually moved seller search out of the main bar and into Advanced Search and direct profile URLs, and the mobile app removed the dedicated box entirely. Nothing is broken — the entry points just moved. Advanced Search on desktop and the ebay.com/usr/username URL on any device are the two methods that have stayed reliable.
