🔍 What does Amazon ASIN Rating Scraper do?

You give it products, and it returns one row per product:

• ⭐ Average star rating (e.g. 4.2)
• 🔢 Total global ratings count (e.g. 2958)
• 📊 Star breakdown: % of 5★, 4★, 3★, 2★ and 1★ ratings (when Amazon shows it on the page)
• 💲 Buy-box price, as a number and as displayed
• 🏆 Best Sellers Rank in the main category and in every subcategory (e.g. #4,827 in Cell Phones & Accessories, #406 in Cell Phone Screen Protectors)
• 📈 Units bought in the past month, from Amazon's "1K+ bought in past month" badge, as a number (1000) you can sort and chart
• 🏭 Brand and 📦 availability ("In Stock", "Only 3 left in stock")
• 🖼️ Main product image
• 🏷️ Product title and 🔗 product link
• 🌍 Marketplace the data came from
• 🕒 Scrape timestamp, so repeated runs build a history
• ✅ Status per product: found, not sold on that marketplace, or blocked

It accepts:

• Bare ASINs: B0G7RYP439
• Product URLs from any supported Amazon site: https://www.amazon.de/dp/B0GDHRZFWH
• Mixed lists pasted straight from a spreadsheet column. Duplicates, blank cells, - and TBD are skipped automatically.

🌍 Which Amazon site gets scraped?

You enter	Scraped on
A bare ASIN, e.g. B0G7RYP439	The Marketplace selected in the input (default amazon.com)
A product URL, e.g. https://www.amazon.co.uk/dp/B0H2BX5FF2	That URL's own site (amazon.co.uk)

So one run can cover the US, UK, Germany, Japan and more. List the same ASIN as URLs on different sites to compare its rating country by country.

⚠️ Amazon ratings are per marketplace. A product can be 4.6★ with 13,000 ratings on amazon.com and 4.1★ with 400 ratings on amazon.de. Always check the marketplace column.

🌟 Key features

• 19 Amazon marketplaces: US, UK, DE, FR, IT, ES, NL, SE, PL, TR, JP, IN, CA, MX, BR, AU, AE, SA, SG
• Fast: ~3,400 products in about 5½ minutes on default settings
• Cheap: $1.60–2 per 1,000 products ($1 on the Free plan), roughly 2× cheaper than typical full Amazon product scrapers
• Fair billing: not-found and blocked products are never charged
• Stable: each parallel session behaves like one real shopper, with its own IP, cookies and real-browser fingerprint, human-like pacing, rotation, and automatic slow-down if Amazon pushes back
• Smart proxies: fast datacenter IPs first, residential only for products that keep getting blocked
• Clean data: incomplete pages are retried instead of saved, and Amazon's "Continue shopping" check page is passed automatically
• Fewer gaps outside the US: Amazon sometimes serves a light product page without the rank and star breakdown (more often on UK, EU and JP sites, and almost always for unavailable listings). The actor spots it and re-fetches once on a fresh session at no extra cost to you; if the page is still light, you get the rating and count with the rank fields left null
• Small footprint: runs on 512 MB, and more memory isn't needed
• Monitored daily with live test runs on amazon.com and amazon.de

⚖️ Why choose this scraper?

	This actor	Typical Amazon product scrapers
Price per 1,000 products	$1.60–2.00 ($1 on Free plan), first 100 every month free	$3–5
Charged for not-found / blocked products	No	Often yes (every dataset row)
Mix several Amazon sites in one run	Yes, from the URL	Usually one country per run
Default memory	512 MB	1–4 GB
~3,400 products	~5½ min	Often much longer (full page parsing)
Output	Focused: rating, count, star breakdown, price, Best Sellers Rank, image	40+ fields you may not need
Star-rating breakdown (5★…1★ %)	Included free	Separate actor, often $4+ per 1,000
Best Sellers Rank in every subcategory	Included (bestSellersRanks)	Often main category only
Monthly sales signal ("bought in past month")	Included, as a number	Often missing or text only
Amazon login / cookies needed	No	Sometimes

If you need ratings, review counts and the numbers around them (star mix, price, rank) without a full product scrape, this is the fastest and cheapest way to get them.

📋 Output fields

Field	Type	Description
asin	string	The product's ASIN
found	boolean / null	true = product page found · false = not sold on this marketplace / delisted · null = blocked after all retries

ratingsCount	integer	Total number of global ratings (0 if none)
starBreakdown	object / null	% of ratings per star, {"5": 69, "4": 9, "3": 7, "2": 6, "1": 9}. null when the page doesn't show it (common outside amazon.com)

bestSellersRanks	array / null	Every Best Sellers Rank on the page, main category first, then each subcategory: [{"rank": 4827, "category": "Cell Phones & Accessories"}, {"rank": 406, "category": "Cell Phone Screen Protectors"}]
imageUrl	string / null	Main product image, high resolution
boughtInPastMonth	integer / null	Amazon's "bought in past month" badge as a number (lower bound): 200+ → 200, 1K+ → 1000. null when Amazon shows no badge (low sellers, many non-US sites)
boughtInPastMonthText	string / null	The badge as displayed, e.g. 1K+ bought in past month

marketplace	string	Amazon site the data came from, e.g. amazon.de
scrapedAt	string	Scrape time, UTC, ISO 8601

childReviewCounts	object / null	Only with child review counts on: written reviews for this exact variant per star, {"all": 94, "5": 72, "4": 8, "3": 7, "2": 6, "1": 1}
childReviewAverage	number / null	Only with child review counts on: average stars of this variant's written reviews
childReviewCountsNote	string / null	Only with child review counts on: why the counts are missing (no cookies, signed out, Business account, blocked)

🔐 Optional: review counts per child ASIN (needs your login)

ratingsCount ("N global ratings") is shared by the whole variation family: every size and color of a product shows the same number. Amazon has no per-child rating total. The only per-child number is on the reviews page filtered to this variant and one star level: "N matching customer reviews". It counts ratings with a written review only, so it is lower than ratingsCount, and each marketplace has its own numbers.

Amazon shows that page only to signed-in shoppers, so this part is opt-in and uses your own session:

1. Sign in to the Amazon store(s) you need with a normal consumer account. Amazon Business accounts get a reviews page without filters and can't see some consumer listings, so they won't work.
2. Export the cookies with any cookie-export browser extension (JSON) and paste them into Amazon cookies. One export can cover several stores; or use {"de": "<cookie header>", "co.jp": "<cookie header>"}.
3. Turn on Child ASIN review counts and run as usual.

Each product needs 6 extra page loads (all + 5★…1★), so these runs are slower. Requests for one store share one session and run a few at a time, like one person browsing. If the cookies expire or belong to a Business account, the run says so in childReviewCountsNote and keeps going with the no-login fields.

Price: free until 23 Nov 2026, then $0.01 per product per marketplace, on top of the normal product price, and only when the counts come back. Rows with a childReviewCountsNote (no cookies, signed out, blocked) are not charged for child counts.

🚧 Not-found and blocked items

Every product you enter gets a row, so nothing silently goes missing:

{ "asin": "B0B7MFZ2SH", "found": false, "marketplace": "amazon.com" }

found: false: Amazon has no product page for this ASIN on this site. Not charged.

{ "asin": "B0XXXXXXXX", "found": null, "error": "Blocked after 6 attempts", "marketplace": "amazon.com" }

found: null: Amazon blocked all 6 attempts, each on a fresh identity and the last ones on residential IPs. Rare; just run those ASINs again. Not charged.

💰 How much does it cost to scrape Amazon ratings?

🎁 Your first 100 products every month are free. After that, from $1.60 per 1,000 products, with bigger discounts on higher Apify plans. It's pay-per-event, so platform usage isn't billed on top.

Your Apify plan	Per product	Per 1,000 products
🎁 Free (try it on your monthly free credit)	$0.001	$1.00
Starter	$0.002	$2.00
Scale	$0.0018	$1.80
Business / Platinum / Diamond	$0.0016	$1.60

Plus $0.005 per run. Not-found and blocked products are always free, and the first 100 found products each calendar month (UTC) cost nothing. The run log shows how many free products you have left.

🔐 Optional child ASIN review counts (needs your Amazon login, off by default): free until 23 Nov 2026, then $0.01 per product per marketplace when the counts come back. The 100 free products don't cover this add-on.

You check (Starter plan)	Cost
100 products once	$0.005 (all 100 free)
1,000 products once	≈ $1.81
10,000 products once	≈ $19.81
500 products every weekday (~22 runs/month)	≈ $21.91 / month

🎁 Free trial: new to Apify? The Free plan's monthly $5 credit covers about 5,000 products at the Free-plan price, every month, enough to test on your real catalog before you pay anything.

💡 Tips for best results

• Test with 10–20 products first to check the marketplace setting and the output format.
• Use full product URLs for non-US products. That way each one is scraped on the right site, even in a mixed list.
• Variants share reviews. Color and size variants of one product usually show the same rating and count, because Amazon pools them.
• Schedule instead of re-running by hand. The scrapedAt field lets you stack runs into a history in Sheets or your database.
• Leave the proxy and memory defaults alone. They're tuned for speed and cost.

🤝 When to use this vs a full Amazon product scraper

• Use this actor when you need ratings, review counts, star mix, price, rank, monthly sales badge and stock for a known list of products, especially many products, often.
• Use a full product scraper when you also need descriptions, bullet points, all images, variants or every seller offer.
• Use a review scraper when you need the individual review texts.

❓ FAQ

Is there a free allowance? Yes. The first 100 products that return data each calendar month (UTC) are free on every plan. The actor keeps the counter in a small key-value store named k-data-lab-free-quota in your own Apify account, holding nothing but the number.

How do I check Amazon ratings for many ASINs at once? Paste them all into the input, one per line. A list of thousands is fine; ~3,400 products take about 5½ minutes.

Which Amazon countries are supported? 19 sites: amazon.com, .co.uk, .de, .fr, .it, .es, .nl, .se, .pl, .com.tr, .co.jp, .in, .ca, .com.mx, .com.br, .com.au, .ae, .sa and .sg.

Do I need an Amazon account, cookies or the Amazon API? No. Only public product pages are read.

Why does a product show found: false? It isn't sold on that marketplace or has been delisted. Check the marketplace, or pass the full product URL. You aren't charged for it.

Why is rating null with ratingsCount: 0? The product has no ratings yet. That's real data, not an error.

Does it return the 5-star / 1-star breakdown or the review texts? The breakdown, yes: starBreakdown gives the % of 5★…1★ ratings whenever the product page shows it. Individual review texts, no. That's what keeps it fast and cheap; use a review scraper for those.

Does it return the subcategory Best Sellers Rank? Yes. bestSellersRank / bestSellersCategory hold the main-category rank, and bestSellersRanks lists every rank Amazon shows for the product, main category first, then each subcategory (often the more useful number for niche products). Categories come in the marketplace's language.

Why are bestSellersRank or starBreakdown null for some non-US products? Amazon leaves them out of the light product page it serves for unavailable listings and, at random, for some visits. The actor retries a light page once on a fresh session; if it stays light, the row keeps the rating and count. Running those ASINs again later usually fills the gaps.

Why is price null for some products? Amazon shows no buy-box price for them: the product is out of stock, sold only by other sellers, or can't be delivered to the marketplace's default location. availability usually says which.

Can I see how many units a product sold? Amazon doesn't publish exact sales, but many listings show a "bought in past month" badge (50+, 1K+, 10K+). The actor returns it as boughtInPastMonth (a sortable number) plus the original text. Combine it with bestSellersRank and run it on a schedule to track sales momentum for your own or competitors' products.

Can I schedule it and send results to Google Sheets? Yes. Save your input as a task, add a schedule, and connect the Google Sheets integration.

Is it legal to scrape Amazon ratings? This actor only collects publicly available product data and no personal data. You're responsible for how you use the results. Check Amazon's terms and the laws that apply to you.

Something doesn't look right. How do I get help? Open an issue on the Issues tab with the run link and a few example ASINs.
