What Terapeak Sourcing Insights Actually Shows You
Last updated: September 2026
Bottom line: Terapeak Sourcing Insights is a free tool built into eBay Seller Center that turns 90 days to 12 months of actual sold-listing data into a category-by-category demand map, and the fastest route to answer "how do i use terapeak sourcing insights for category comparison?" is to pull the same metric — sell-through rate — for every category you're weighing before you spend a dollar on inventory.Sellers open it from Seller Center > Research, type in a keyword or browse by category tree; get back average sold price, total sold units, sell-through rate; the top search terms buyers actually used to find those listings.
None of that is a projection or an AI guess — it's what genuinely sold on eBay in the window the tool is pulling from, which is the whole reason experienced resellers treat it as a pre-purchase filter rather than a nice-to-have.
Where this pays off hardest is exactly the comparison use case. Say you've got $600 to spend and you're deciding between a lot of women's western boots and a lot of vintage band t-shirts.
Pull both categories in Sourcing Insights, and you might see boots sitting at a 38% sell-through rate with a $42 average sold price, against t-shirts at 61% sell-through. A $28 average. Boots move slower but carry more margin per unit; shirts turn faster at lower ticket size.
That single side-by-side is how do i use terapeak sourcing insights for category comparison in practice — not reading one category in isolation. Running the same two or three metrics across every option on your shortlist before the sourcing decision gets made.
Why Category-Level Data Beats Gut Instinct
A seller who's been listing Carhartt jackets for two years develops real instinct about that niche. Instinct doesn't transfer to a updated category like Coach handbags or Pokémon sealed product. Sourcing Insights closes that gap in about five minutes of searching instead of weeks of trial listings.
It won't tell you which specific jacket size sells fastest or predict next month's demand — it's backward-looking sold data, not a forecast —. For the narrow question of "which of these categories is worth my sourcing dollars right now," it's the closest thing to ground truth eBay gives sellers for free.
How to Run a Category Comparison in Terapeak Step by Step
- Open Seller Base and click Research under the Growth tab — that's where eBay hosts Sourcing Insights, and it's included free with any Store subscription, so there's no separate signup or fee to enable it.
- Pick your first candidate category from the tree (or type a keyword like "vintage Levi's 501" into the search box) and note the three headline numbers: average sold price, total units sold, and sell-through rate for the date range shown.
- Switch the date range to the longest window your account can see — Basic Store sellers typically get 90 days of sold history, while Premium and Anchor Store tiers see up to 12 months, and that longer window smooths out one-off spikes from a single viral listing.
- Repeat step 2 for every category on your shortlist, writing the numbers down side by side. This is the actual mechanics behind how do i use terapeak sourcing insights for category comparison — the tool shows one category at a time, so the comparison happens in your own spreadsheet, not inside eBay's interface.
- Check the "Top Search Terms" panel for each category. If you're comparing men's streetwear to women's handbags, for example; streetwear shows "Jordan 4" and "Carhartt WIP" as top terms with strong search volume, that tells you which sub-niches inside the category are actually driving the sold units, not just the category label as a whole.
- Cross-reference sell-through rate against average price to rank your shortlist by capital efficiency. A category selling at 55% sell-through and a $35 average moves roughly $19.25 of gross revenue per listing slot per cycle, versus a 30% sell-through category at $70 average moving about $21 — close enough that fees and sourcing cost per unit should break the tie, not sell-through alone.
- Confirm the finding against active listing count in the same category. If 4,000 sellers are already listing "graphic tees 90s" against your projected 61% sell-through, expect real-world performance closer to the bottom of that range once your listings compete for the same buyer searches.
- Lock in a sourcing budget split based on the ranked list — most operators we see run an 70/30 or 60/40 split between their top two categories rather than betting everything on the single highest sell-through number, since Sourcing Insights data is historical, not a forward guarantee.
Reading the Numbers Instead of Just Collecting Them
Someone comparing thrifted denim (average $32 sold price, 45% sell-through) against a wholesale lot of graphic tees (average $18, 58% sell-through) needs to run both numbers against what each item actually costs to acquire, not just which one eBay shows selling faster. denim (average $32 sold price, 45% sell-through) against a wholesale lot of graphic tees (average $18, 58% sell-through) needs to run both numbers against what each item actually costs to acquire, not just which one eBay shows selling faster.
That's the real answer to how do i use terapeak sourcing insights for category comparison for anyone treating this as a sourcing decision instead of a curiosity search: the tool supplies demand. Price, you supply cost and margin; the category that wins is whichever produces the higher return per sourcing dollar, not the higher raw sell-through percentage.
Quick tangent — I use the Closo Demand Insights to track what is actually moving right now, which saves me about three hours a week of manual search. Worth a peek before your next haul.
What Trips Sellers Up When Comparing Categories
Bottom line: the single biggest mistake we see is treating a 90-day sell-through snapshot as a permanent verdict on a category, when categories like "holiday sweaters" or "graphic hoodies" can swing 20 percentage points in sell-through between a September pull. A December pull.Anyone asking how do i use terapeak sourcing insights for category comparison?
for the first time tends to run the search once, screenshot the numbers, and treat that as settled fact. Sourcing Insights is a snapshot of what sold in a window, not a permanent ranking. The categories most prone to seasonal swing — holiday décor, cold-weather outerwear, swimwear — are exactly the ones where a single pull misleads you the most.
A second pitfall is comparing categories at different levels of the tree. Pulling "Women's Clothing" as a whole against the narrower "Women's Handbags" subcategory isn't a fair fight — the broad category will always show more total units sold. A wider price spread, because it's aggregating dozens of sub-niches.
If you're deciding between denim and handbags, drill both down to a comparable depth: "Women's Jeans" against "Women's Handbags," not "Women's Clothing" against "Women's Handbags." Sellers who skip this step end up thinking a whole department outperforms a boutique niche by volume, when the real comparison was never apples to apples in the first place.
Fee math is the third blind spot, and it's the one with the clearest dollar impact. eBay's final value fee for most categories runs around 13.25% of the total sale price including shipping, but categories like Trading Cards.

Select Business & Industrial listings carry different fee schedules — trading cards on eBay have historically drawn separate treatment closer to 13.6% plus a small per-order amount above certain thresholds. A category showing a $60 average sold price and 50% sell-through looks identical to one showing $60.
50% until you net out the fee difference, and that gap compounds across 200 units a year into real money. This is where how do i employ terapeak sourcing insights for category comparison stops being a data-pulling question.
Becomes a net-margin question — the tool gives you gross numbers, and the fee schedule for that specific category is on you to check separately. , according to Federal Reserve economic indicators
The Listing-Competition Trap
The fourth pitfall is ignoring how many other sellers are already crowding a category with strong Sourcing Insights numbers. A short list of what to check before locking in sourcing dollars to a "winning" category:
- Active listing count in that exact subcategory — not the parent category — pulled from a live eBay search, not from Sourcing Insights itself.
- Average listing age of the top 20 search results, since a category full of week-old listings signals sellers are still testing it, while one full of year-old listings signals a saturated, slow-moving niche.
- Whether a handful of Top Rated sellers with 10,000+ feedback dominate page one, which usually means new entrants compete on price, not visibility.
- Return rate norms for the category — apparel categories like women's dresses run mainly higher return rates than accessories like belts or jewelry, which quietly eats into the margin a raw sell-through number never shows.
A seller comparing sourcing $400 into a lot of designer sunglasses against $400 into a lot of graphic tees needs all four of those checks, not just the headline sell-through rate, because the tees might show a stronger number in isolation while carrying triple the competing listings per buyer search.
Terapeak Sourcing Insights: Common Questions
Is Terapeak Sourcing Insights free to adopt?
Yes. Sourcing Insights is bundled into eBay Seller Center at no extra charge for anyone with an active Store subscription, which starts around $27.99 a month for a Basic Store.
There's no separate Terapeak fee anymore — eBay folded the standalone Terapeak product into Seller Center several years back, so if you're already paying for a Store tier, the research tool is included rather than an add-on purchase.
How do i use terapeak sourcing insights for category comparison?
Open Seller Focal point's Research tab, pull sell-through rate, average sold price. Total units for one category, record the numbers, then repeat the same pull for each category on your shortlist. eBay shows one category at a time, so how do i use terapeak sourcing insights for category comparison?
really comes down to running that search repeatedly and building your own side-by-side table — a category at 50% sell-through. $40 average against one at 35% and $65 average, ranked by margin, not raw volume.
Does Sourcing Insights work for categories outside the US eBay site?
Coverage is strongest on eBay.com; international sites like eBay.co.uk and eBay.de have thinner historical data and, in some cases, no Sourcing Insights access at all for certain seller accounts.
A seller sourcing for a UK-facing store should treat any category comparison run through the US tool as directional evidence about global demand trends, not a precise stand-in for UK-specific sell-through numbers. , according to U.S. Census Bureau economic data
How far back does the sold-listing data actually go?
It depends on your Store tier. Basic Store sellers typically see 90 days of sold history, while Premium and Anchor tiers can pull up to 12 months.
For a category like winter coats, a 90-day window pulled in July will badly understate real demand, which is exactly why anyone repeatedly asking how do i use terapeak sourcing insights for category comparison? for seasonal goods should note the pull date next to every number they record.
Can Sourcing Insights replace a full sourcing plan on its own?
No.
It answers "did this sell, and roughly how fast," not "what will my landed cost, shipping weight, or return rate be." A seller comparing a $500 lot of sneakers against a $500 lot of kitchenware still needs separate research into authentication risk, fee schedules, and storage space — Sourcing Insights narrows the shortlist, it doesn't finish the sourcing decision by itself.
Put the Comparison to Work Before You Spend
Bottom line: the sellers who turn a $500-$2,000 sourcing budget into consistent profit are the ones who run the category comparison before the purchase, not after the boxes arrive.If you've made it this far wondering how do i adopt terapeak sourcing insights for category comparison?, the honest next step isn't more reading — it's opening Seller Focal point, pulling sell-through and average price for your top two or three candidate categories, and writing the numbers down side by side today.
Data that sits unused in a browser tab doesn't change a sourcing decision; a comparison table with three categories ranked by margin does.
For sellers weighing a specific lot purchase rather than an open-ended category, Closo Wholesale lists liquidation lots with manifests broken out by category, which pairs directly with this kind of research — you can check a lot's dominant category against its own Sourcing Insights numbers before agreeing capital, instead of buying first and researching after the pallet is already on a truck.
Where to Go From Here
Closo's blog base covers the adjacent pieces of this decision that Sourcing Insights alone won't answer: reading a liquidation manifest line by line, calculating true landed cost once freight and processing time are factored in; setting a realistic sell-through target for a new category in the first 90 days rather than assuming week-one numbers hold.
A seller who ran the comparison above and landed on, say, women's handbags over men's sneakers still needs those follow-up pieces before wiring money to a supplier — the category comparison narrows the field, the rest of the research closes the gap between a strong category and a good purchase.
Bookmark the Closo blog center, run your own comparison this week using the eight-step process above, and treat the exercise as a recurring habit rather than a one-time lookup. Sellers who revisit how do i use terapeak sourcing insights for category comparison?
every quarter — not just once when they're starting out — catch seasonal shifts and new competition before they show up as a slower sell-through rate on their own listings.
