Marketplace product research tools UK: a practical guide to Amazon, eBay, Etsy and OnBuy
A practical guide to UK product research tools for Amazon, eBay, Etsy and OnBuy, naming Jungle Scout, Helium 10, Keepa, Terapeak, ZIK Analytics, EverBee and costs.
What to take away
- Product research tools answer one questionis there repeat demand for this item on this UK marketplace at a margin after fees and VAT?
- Amazon UK data leans on rank and keyword estimates. Jungle Scout, Helium 10 and Keepa are common starting points.
- eBay UK sellers can use Terapeak inside Seller Hub, and ZIK Analytics from around £15 a month (about 19 US dollars), plus UK VAT if it applies.
- Etsy UK sellers can try EverBee from around £23 a month (about 29 US dollars) and eRank, with a free plan and paid Pro near £8 a month (about 10 US dollars).
- OnBuy has no product research tool. Use its seller dashboard and category pages, then verify by hand.
Where UK demand data comes from
Tools rarely invent data. Most pull from public listing pages, search suggestions, or seller panels.
Amazon UK figures are modelled from category rank. Jungle Scout and Helium 10 show monthly sales estimates as ranges. Keepa shows price and rank history, not sales counts.
eBay UK sold listings are visible to anyone. Terapeak uses that sold data and sits inside eBay Seller Hub. ZIK Analytics adds bulk sold searches.
Etsy UK and OnBuy publish thinner histories. EverBee and eRank lean on search interest, favourites and listing counts. No widely used tool covers OnBuy. Check its category pages and seller dashboard, track listing and seller counts, and run one small test order before buying stock.

Sourcing, tracking and listing are three jobs
The first two get sold in one bundle and are not the same. Competitor tools watch existing listings. Sourcing tools hunt for items you have not listed, then test whether they can be bought and shipped at a profit.
Jungle Scout and Helium 10 include sourcing databases. Keepa tracks price and rank changes on Amazon listings you already watch. Dynamic pricing sits between the two. dynamic pricing explains the mechanics.
Many suites bundle sourcing and tracking, then charge once. Check whether sourcing credits run out before tracking does.
Listing is the third job. It covers creating and syncing listings, stock levels, prices and order routing across marketplaces. A sourcing tool can find a product that never gets listed correctly. eBay and OnBuy feeds differ, so test one product end to end.
Our comparison of multichannel listing software for UK marketplaces covers how the main feeds handle eBay and OnBuy side by side.
Five steps to shortlist a tool
- Write down the marketplaces you sell on today, not the ones you might add.
- Ask each vendor how the demand number is produced and how often it refreshes.
- Run the tool on ten products you already sell and compare its estimate with your real orders. Use Jungle Scout or Helium 10 for Amazon UK. Use Terapeak for eBay UK. Use EverBee or eRank for Etsy UK.
- Check what happens to saved lists if you cancel.
- Price the plan against gross profit per month, not turnover.
Where the costs sit
Entry plans often start free. eRank's free tier caps keyword searches per day. EverBee's free tier caps searches per month. Helium 10's free tier caps product searches per month. The exact number changes, so check the plan page. Terapeak sits inside eBay Seller Hub, with access tied to your eBay plan.
Keepa has free charts, with paid access around £16 a month (about 19 euros), plus UK VAT if it applies.
Paid tiers charge by tracked products, searches or credits. Helium 10 Starter is around £31 a month (about 39 US dollars), Jungle Scout Starter around £39 (about 49 US dollars), ZIK Analytics from around £15 (about 19 US dollars), and EverBee paid plans from around £23 (about 29 US dollars). Check whether UK VAT is added at checkout.
Prices are set in US dollars or euros, so GBP figures are typical conversions and move with the exchange rate.
Ask what the meter counts before comparing quotes. A cheap plan that caps searches can cost more than a larger plan you never max out.
Demand estimates are quoted gross. If you are VAT-registered, work out margin on the net figure, and check the VAT registration rules on GOV.UK.
Turning research into stock decisions
Research only pays if stock can be replenished. Before you commit to a supplier, check how inventory software for UK marketplace sellers ties a reorder point to the demand figure the tool gave you.
A reorder point that ignores overseas lead times will trigger late. Test that link with one product before scaling across marketplaces.
Common questions
Do I need a paid tool to find products for Amazon UK?
Not at the start. Amazon's Best Sellers lists are free and dated. Keepa has free charts. Helium 10 and Jungle Scout have free entry options.
Are trending products on eBay UK a reliable demand signal?
Partly. Sold listings show what changed hands, but a one week spike is not a trend. Terapeak gives sold data inside Seller Hub. ZIK Analytics adds bulk checks from around £15 a month (about 19 US dollars), plus UK VAT if it applies.
Can one tool cover all four marketplaces?
Rarely well. Helium 10 and Jungle Scout focus on Amazon. Terapeak focuses on eBay. EverBee and eRank focus on Etsy. OnBuy is often missing, so check the marketplace list before you pay.
