Helium 10 vs SellerSprite vs AMZScout: which is best for a small Amazon UK seller? I tested all three on my own listing to find out.

I sell kitchen products on Amazon UK under DTDF Essentials. On 4 November 2026 I ran five tests on SellerSprite and AMZScout using my own glass cup washer listing (ASIN B0FBMLX2JJ) and a real competitor, and compared them with my Helium 10 tests on the same listing from October. All tests were on the amazon.co.uk marketplace, not the US. So if you are weighing up Helium 10 vs SellerSprite for a UK shop, this is real UK data.
Short version: SellerSprite gave me the most UK data for free. Helium 10 found more keywords. AMZScout locked every tool on two new accounts until I paid.

How I tested Helium 10 vs SellerSprite
My product: Glass Cup Washer with 3 Suction Base (B0FBMLX2JJ), £9.99, BSR about 39,900 in Grocery, 2 ratings. You can also buy it direct from my own shop, DTDF Home & Kitchen.
Competitor: Hniuyun Glass Washer with Suction Base (B0CBKBJ49G), £11.89, 91 ratings.
Five tests: 1) reverse ASIN on my listing, 2) keyword research for “glass cup brush” and “cheese grater”, 3) sales estimate for the competitor, 4) AI listing tools, 5) what is free and what is locked.
SellerSprite and AMZScout on the same day (4 Nov) with new accounts; Helium 10 free plan tested in October. All on Amazon UK. I did not pay for any of the three.
Test 1: Reverse ASIN in Helium 10 vs SellerSprite
Helium 10 found 54 keywords for my listing, the most of the three. You can read my full test in my Helium 10 free plan review.
SellerSprite found 30 keywords (28 organic, 4 from sponsored ads). Fewer keywords. However, each one came with monthly searches, my organic rank and suggested PPC bids. The ones with real volume:

What this told me: first, I already rank in the top 10 for long phrases like “wine glass washer” (#6), but I’m far back on the big terms. “Cup cleaner” is cheap to bid on and has real volume, so as a result it’s going into my ads.
AMZScout: the Reverse ASIN Lookup 2.0 tool showed “It seems your tools subscription has expired. Click BUY NOW”, on a brand-new account. I tried a second new account with a different email and got the same message.
Test 2: Keyword research, Helium 10 vs SellerSprite
This was the most useful test. In SellerSprite’s Keyword Mining tool:
“glass cup brush” returned only 6 results, and only one was relevant. In other words, UK shoppers barely search this phrase. Instead, they type “cup cleaner”, “bottle washer” or “glass washer”. If I had built my ads around “glass cup brush” I’d have wasted money.
“cheese grater” returned 175 keyword ideas: “cheese grater” 49,273 searches/month (up 18%), “grater” 17,670, the misspelling “greater” 9,146, “graters for kitchen” 6,435 (up 116%) and “box grater” 2,415, where about 20% of searchers bought.
Helium 10’s free keyword tools also work for this, with daily limits. AMZScout’s Keyword Search showed the same “subscription has expired” message.
Test 3: Competitor sales estimate
SellerSprite estimated my competitor (B0CBKBJ49G) sells about 164 units a month, around £1,950 revenue, at £11.89 with 91 ratings. It also showed a second listing from the same seller launched in April 2026. That’s useful because it shows a product like mine can do this volume once it has reviews.
I didn’t re-run this on Helium 10 this round (I’ll add it in an update). On AMZScout I couldn’t get past the lock screen.
Test 4: AI listing tools
SellerSprite’s Listing Builder showed 1,000 AI credits a month. You add keywords, click “Keywords Analysis” first (it won’t generate without this), then generate. It wrote this title for me:
Double Sided Bristle Glass Washer with 3 Suction Cups for Kitchen Sink
It’s usable. However, it left out “cup cleaner” and “bottle washer”, the two biggest keywords it had just found. Therefore, check the AI’s work against the keyword data before you paste it into Seller Central.
Test 5: What’s free in Helium 10, SellerSprite and AMZScout
SellerSprite: on my new account, all four tests above worked with no lock screens. Without logging in, the free browser extension still showed the sellers on a listing (it showed me who took my Buy Box on another product), but sales and revenue were hidden.
Helium 10: a real free plan with limited daily searches. Good for a first look; the deep tools need a paid plan.
AMZScout: everything I tried in the web app was locked on two new accounts. If you want to test it, be ready to pay for a month.
Real example: who took my Buy Box
On my knife sharpener, Seller Central only told me I’d lost the Featured Offer to someone at £5.60. The free SellerSprite extension showed me exactly who: two other sellers on my listing, one at £5.60 with 999 units in stock.
SellerSprite (free extension, not logged in): all 3 sellers on my listing. Sales and revenue are hidden (****) without an account.Seller Central: Featured Offer lost to £5.60, but no seller name.
Helium 10 vs SellerSprite: which should a small UK seller choose?
Just starting, small budget: start with SellerSprite. It gave me UK search volumes, bids, competitor sales and AI listing help without paying.
You want the most keywords and a big toolset:Helium 10 found the most keywords and has the best free plan for daily checks. See also Helium 10 vs Jungle Scout.
AMZScout: I can’t recommend what I couldn’t test. I’ll update this page if I test a paid month.

What I’m changing on my own listing
Adding “cup cleaner” and “bottle washer” to my title and bullets.
Bidding on “cup cleaner” (about £0.30) in a manual campaign.
Dropping “glass cup brush” as a main keyword, because almost nobody in the UK searches it.
In short, in my Helium 10 vs SellerSprite test, SellerSprite gave a small UK seller more for free, while Helium 10 found more keywords. I’ll come back and update this page with the ranking results.
