eBay product research: how to find what sells before you list

The cheapest listing to fix is the one you never make. Good eBay product research tells you, before you spend time on photos and descriptions, whether people are buying an item, how many others are selling it, what it sells for, and whether it's something you're allowed to list at all.

This guide works through each of those checks in turn, then shows how to turn research into a shortlist that a second person reviews before anything is listed.

eBay product research starts with demand

Demand is what has sold, not what is listed. A category full of listings can be full of items nobody buys. Look at sold items over a recent period: how many sold, how steadily, and at what prices.

eBay's own search lets you filter to sold items, which gives a quick read on a single product. For whole categories and keywords you need monthly sales figures, so you can compare one area with another rather than judging items one at a time.

Start broad and narrow down. A top-level category tells you little on its own; the useful signals are a few levels down, where a category is specific enough that its items genuinely compete with each other. Work from the top category through its subcategories to the leaves, and compare like with like.

What sell-through rate tells you on eBay

Sell-through compares how much sells with how much is listed over the same period. Sellers define it slightly differently, but the idea is the same: a high sell-through means items are selling well relative to the number on offer, and a low one means plenty of stock is sitting unsold.

Read it alongside sales volume. A high sell-through on a handful of sales is a niche; a high sell-through on thousands of sales is a busy market where buyers are still finding what they want. A low sell-through with high sales can still work, but you'll need a reason for a buyer to pick your listing over the rest.

How to size up the competition on eBay

Count the live listings, then look at who's making the sales. If a few sellers take most of them, ask why: price, feedback, faster dispatch, better photos, or simply being there first. If sales are spread widely, there's more room for someone new.

Then look closely at the leading listings:

• Are the titles, photos and item specifics good, or could you do better?
• How fast do they dispatch, and do they offer free postage?
• How many variations do they offer, and which ones seem to sell?
• Are they all selling the same item, or something that only looks the same?

Competition isn't a reason to avoid a market. Weak listings in a market with strong demand are an opportunity; strong listings in a market with weak demand are not.

Finding the right price band on eBay

Look at what similar items typically sell for, and where most sales cluster. That band is what buyers expect to pay. Listing far above it needs a clear reason; listing far below it can start a race to the bottom.

Then work back from the typical price to what you can afford to pay for the item after eBay's fees, postage and your margin. If the numbers only work at the very top of the band, the product probably isn't for you. Our guide to working out real eBay profit has the formula to use.

For items with variations, check each option separately. One size or colour often carries most of the sales, and an option that costs you more can lose money at the same price as the others.

Seasonality and shopping days on eBay

Demand moves with the calendar: garden furniture in spring, school supplies in late summer, gifts from November onwards. Look at sales across a whole year before judging a product on one month, and list seasonal stock early enough to build some sales history before the peak.

Shopping days differ by country, which matters if you sell on more than one eBay site. Mother's Day falls in March in the UK and Ireland but in May in the US, Canada, Australia and much of Europe. Black Friday, Christmas and each country's public holidays also shape when buyers shop and when the post runs.

VeRO brands and restricted items: check before you hunt

Some products are risky to list however well they sell. Under eBay's Verified Rights Owner (VeRO) programme, brands and other rights owners can ask eBay to remove listings they believe infringe their rights, and repeated removals can lead to restrictions on your account.

Other items are restricted or prohibited by eBay altogether, or allowed only under conditions. These lists are long, they change, and the rules can differ by site. Check eBay's current policies on prohibited and restricted items, and its VeRO information, before you put time into a product.

The time to check is before anyone researches the product further, not after it's drafted. A good research process flags these items at the start, which is why SellingSquads marks VeRO brands and restricted items before anyone hunts them.

Turning research into a reviewed shortlist

Research is only useful if it leads to good decisions. Two habits help.

First, write every candidate down in one shared place with the same facts: what it is, the demand and sell-through you found, the typical price, your expected profit for each option, and any risk you noticed.

Second, have someone else review it before it's listed. The person who found a product is naturally keen on it; a second pair of eyes catches the brand on the VeRO list, the variation that loses money, or the market that's quieter than it looked. A reviewer can approve it, send it back with a question, or reject it with a reason, and that reason teaches the whole team.

A reviewer's questions can be the same every time:

• Is there steady demand, or a single good month?
• Is the market moving, judging by sell-through and sales together?
• Can a new listing stand out against the leading ones?
• Does every option make a profit at the typical price, after eBay's fees and postage?
• Is the brand or item free of VeRO and restricted-item problems?
• Is there a shopping day ahead that changes the timing?

Once approved, a product moves on to listing. Our guide to AI eBay listings that get found covers turning it into a listing that sells.

How SellingSquads helps with eBay product research

SellingSquads' Discover ranks eBay categories and keywords by what sells, using the figures this guide has walked through:

• Monthly sales, for demand.
• Live listings, for how crowded a market is.
• Sell-through, for whether it's moving.
• Typical price, for the band buyers expect.

You can start at a top category and work down through its subcategories to the leaves, or start from a keyword, comparing like with like at every level. VeRO brands and restricted items are flagged before anyone hunts them, so risky products are set aside at the start rather than after the work is done.

Product hunting turns research into a reviewed shortlist. Hunters add products to a shared list, and SellingSquads checks the profit on every option at the market price, with the account's real eBay fees and postage, so the variation that loses money shows up before anyone lists it. Reviewers approve, send back or reject, and approved products draft themselves as AI listings, ready for a final check before they go live.

For seasonality, SellingSquads' shopping calendar shows each country's shopping days and public holidays, with reminders, so the team can research and list ahead of the peak rather than during it. And once products are live, SellingSquads' stock and price watch alerts you if the place you buy one from runs out or puts its price up, so a product that passed review keeps earning its place.

Every product hunted is recorded against the person who hunted it, in the same activity log as the rest of the team's work, and an announcement can set the team's focus for a coming shopping day, with reminders as it approaches.
