Why use this tracker

• 📈 Rank tracking built in. Every run stores a snapshot of each list; the next run returns previousRank, rankChange, rankChangePercent, isNewEntrant, plus per-list new entrants, dropouts, top risers and top fallers. No spreadsheets, no diffing on your side.
• 🔁 Movers & Shakers for any category, on your schedule. rankChangePercent uses Amazon's own Movers & Shakers formula (rank 30 → 10 = +200%), so a daily scheduled run gives you a Movers & Shakers view of Best Sellers or New Releases in every category you track — including the ones where Amazon's own page shows nothing.
• ✅ The whole top 100, verified. Amazon renders ranks 1–30 in the page and lazy-loads 31–50 (and again on page 2). This actor fetches the lazy-loaded part directly and checks that every product Amazon lists up to your top N arrived. A list that comes back short is retried on a fresh session and, if it still can't complete, reported as FAILED — never returned as if it were whole. When Amazon itself leaves a position empty or shows "This item is no longer available", the summary says so (rankGaps, unavailableRanks) instead of hiding it.
• 🔎 Start from a keyword. Don't know the category? Type air fryer and the actor finds the category the top search results rank in (Air Fryers) and returns that list. Amazon's search no longer has a Department filter, so it reads the Best Sellers Rank of the top organic results instead.
• 🏷️ Track specific ASINs. Give it your products (or competitors') and each run returns their Best Sellers Rank in every category they appear in, with the change since the last run.
• 🌳 Whole category trees. Start from a department (or all departments) and crawl sub-categories down to the depth you set, with a safety cap on the number of lists.
• 🌍 11 marketplaces, local prices. US, UK, DE, FR, IT, ES, CA, JP, IN, MX, AU, with the display currency pinned to the marketplace (EUR on amazon.de, not USD).
• 🛡️ Battle-tested anti-blocking. The same datacenter → residential proxy escalation, plain-browser identity and retire-on-captcha stack as our Amazon Product Scraper.
• 🔒 Public pages only. No login, ever.

How to track Amazon Best Sellers rank changes

1. Open the actor and add one or more list URLs (e.g. https://www.amazon.com/gp/bestsellers/electronics), category node IDs or keywords — and/or ASINs to track.
2. Click Start. The first run records a baseline snapshot.
3. Schedule the same input (daily is typical). Every later run returns rank changes, new entrants and dropouts against the previous run.
4. Download JSON, CSV or Excel, or read it through the API.

Input examples

A few lists by URL (the marketplace comes from the domain):

{
    "listUrls": [
        { "url": "https://www.amazon.com/gp/bestsellers/electronics" },
        { "url": "https://www.amazon.de/gp/bestsellers/ce-de" },
        { "url": "https://www.amazon.co.uk/gp/new-releases/books" }
    ],
    "topN": 100
}

By category node ID, Best Sellers and New Releases:

{ "categoryNodeIds": ["172541", "12097478011"], "marketplace": "US", "listTypes": ["bestsellers", "new-releases"] }

A department and its direct sub-categories, top 20 each:

{ "categoryNodeIds": ["electronics"], "crawlCategoryTree": true, "maxCategoryDepth": 2, "maxLists": 40, "topN": 20 }

By keyword (the actor picks the category; it's shown in each list's source, e.g. keyword "air fryer" → Air Fryers):

{ "keywords": ["air fryer", "yoga mat"], "marketplace": "US", "topN": 50 }

Track your own products' Best Sellers Rank:

{ "asins": ["B0BJ1SWDNB", "https://www.amazon.de/dp/B0H4KNCZDN"] }

Each tracked ASIN returns one record:

{
    "recordType": "asin",
    "asin": "B0BJ1SWDNB",

Input	Description
listUrls	Any Amazon list URL: /gp/bestsellers/…, /gp/new-releases/…, /gp/movers-and-shakers/…, /gp/most-wished-for/…, /gp/most-gifted/… or /zgbs/….
categoryNodeIds	Browse node IDs (172541) or department slugs (electronics, ce-de). Combined with marketplace and listTypes.
keywords	Product types (air fryer). Each resolves to the category its top search results rank in, then fetches that list. Combined with marketplace and listTypes.
asins	ASINs or product URLs to track: Best Sellers Rank in every category, with the change since the last run.
marketplace	US (default), UK, DE, FR, IT, ES, CA, JP, IN, MX, AU.
listTypes	bestsellers (default), new-releases, movers-and-shakers, most-wished-for, gift-ideas.
topN	Ranks per list, 1–100 (default 100).
crawlCategoryTree	Also scrape sub-categories. With no URLs or node IDs, starts from all departments.
maxCategoryDepth	Levels to crawl (default 1).
maxLists	Cap on lists per run when crawling the tree (default 50).
trackingStoreName	Named key-value store holding the latest snapshot of each list and ASIN (default amazon-bestsellers-rank-history). Clear it to turn tracking off.
previousDatasetId	Compare with a specific earlier run's dataset instead.

How rank tracking works

After each list, the actor saves its ranking (ASIN + rank, up to 100 entries) to the rank history store, a named key-value store in your Apify account. The next run that scrapes the same list compares against it:

• previousRank / rankChange: where the product sat last time and how many positions it gained (positive = up).
• rankChangePercent: Amazon's Movers & Shakers formula, (previousRank − rank) / rank × 100.
• New entrants: products ranked within last run's top N that weren't there before (isNewEntrant: true).
• Dropouts: products that were inside today's top N last time and are gone now, listed on the summary record with their previous rank.

Tracked ASINs work the same way, per category: each category's rank is compared with the last run's.

Lists are matched by listKey (marketplace:listType:category), so a URL, a node ID and a keyword that resolve to the same category share history. Use different trackingStoreName values to keep separate histories (e.g. a daily and an hourly schedule).

Retention: named key-value stores never expire, so tracking survives indefinitely; each run overwrites a list's snapshot with the newest one. A run's own dataset expires after your plan's data-retention period, so to compare against a specific older day with previousDatasetId, keep (name) that dataset.

What data can it extract?

Field	Description
rank	Position in the list, 1–100
previousRank, rankChange, rankChangePercent, isNewEntrant	Rank movement since the previous snapshot
asin, title, productUrl, imageUrl	Product identity (largest image size available)
price, priceText, listPrice, currency	Price as shown on the list (first number of a range), ISO currency
rating, reviewCount	Star rating and number of ratings
byline, format	Author/artist and format on media lists (books, music, video)
isPrime, badges	Prime flag and card badges, when shown
listType, marketplace, categoryName, categoryNodeId, categorySlug, categoryPath	Which list the product came from
salesRankChangePct, salesRank, salesRank24hAgo	Amazon's own Movers & Shakers figures, when Amazon shows that list
keyword	The input keyword a list was resolved from
ASIN record	salesRank, salesRankCategory, previousSalesRank, salesRankChange, and ranks (every category with rank, previous rank, change, node ID) — one per tracked ASIN; status NO_RANK when the product page shows no Best Sellers Rank (common for Amazon devices and some brands)
Summary record	status, availableProducts, totalProducts, rankGaps, unavailableRanks, newEntrants, dropouts, topRisers, topFallers, previousScrapedAt — one per list

Summary status values: OK; EMPTY (Amazon shows no items for this list); NOT_FOUND (Amazon doesn't recognize the category on that marketplace, or a keyword couldn't be matched to a category); FAILED (couldn't get a complete list after all retries — the error is in message); BUDGET_LIMIT (the run hit your maximum cost).

How much will it cost?

Pay-per-event: $0.004 per ranked product — $4 per 1,000 — and $0.004 per tracked ASIN that shows a Best Sellers Rank, plus $0.005 per run when it compares with a previous snapshot, and a negligible $0.00005 actor-start fee. Summary records, empty lists, failed lists and ASINs without a rank are never billed; resolving a keyword to its category is free (you pay for the list it returns). Paid Apify plans get lower prices automatically (down to $3.60 per 1,000 on GOLD and above). Current prices are always on the Pricing tab.

Worked example — tracking 10 categories, top 100, once a day:

• 10 lists × 100 products = 1,000 products × $0.004 = $4.00
• rank comparison = $0.005, actor start = $0.00005
• ≈ $4.01 per day. Tracking only the top 20 of the same 10 categories costs ≈ $0.81 per day.

Tracking 50 of your own ASINs daily costs 50 × $0.004 + $0.005 ≈ $0.21 per day.

Use topN and maxLists to bound spend precisely.

Movers & Shakers, Most Wished For and Gift Ideas

Amazon has shown no items on its Movers & Shakers, Most Wished For and Gift Ideas pages since spring 2026, on every marketplace we checked ("Sorry, there are no movers and shakers available in this category"). The actor still accepts these list types and will return their items, including Amazon's own salesRankChangePct, if Amazon brings them back. Until then they return an EMPTY summary at no charge.

To see the biggest movers today, track Best Sellers on a schedule: topRisers and rankChangePercent give you the same signal Amazon's page used to, for any category.

Need more product detail?

The list pages carry rank, price, rating and the basics. For brand, full specs, seller, availability, images and descriptions, feed the ASINs into our Amazon Product Scraper. For review text and Amazon's "Customers say" AI summary, use our Amazon Reviews Scraper. Both chain neatly after this actor with an Apify integration.

Integrations

Export to Google Sheets, Google Drive, S3 or a database; automate with Zapier, Make, n8n and webhooks (e.g. alert when a product enters your category's top 10); schedule recurring runs; or call it from anywhere through the Apify API and the JS/Python clients.

FAQ

How do I get daily Amazon Best Sellers rank changes? Schedule this actor with the same input every day. The first run stores a baseline; every run after that returns previousRank, rankChange, new entrants and dropouts per list automatically.

Can it get all 100 best sellers in a category? Yes. Amazon splits each list into two pages of 50 and lazy-loads half of each page; the actor fetches all of it and verifies every listed product arrived. Occasionally Amazon itself skips a rank or shows "This item is no longer available" at one; you then get 99 products and the summary names the position.

Where do I find a category's node ID? Open the category's Best Sellers page on Amazon; the number at the end of the URL (e.g. /gp/bestsellers/electronics/172541) is the node ID. Or just paste the whole URL into listUrls — or type a keyword and let the actor find the category.

How does keyword mode pick a category? It searches Amazon for your keyword and reads the Best Sellers Rank on the top organic (non-sponsored) results' product pages, stopping as soon as two of them agree on a sub-category (at most five pages). The winning category and the vote are in the log and in each list's source. Broad keywords ("gift") spread across categories; specific product types ("air fryer", "yoga mat") resolve cleanly.

Can I track my product's Best Sellers Rank (BSR) over time? Yes. Add its ASIN to asins and schedule the actor. Each run returns the rank in every category shown on the product page and the change since the previous run. Some products (Amazon devices, some brands) show no rank on their page; they come back as NO_RANK and aren't billed.

Why is a Movers & Shakers list empty? Amazon currently shows no Movers & Shakers items on any marketplace we checked. See above; track Best Sellers to compute movers yourself.

Why are prices on amazon.de or amazon.co.jp different from what I see? Amazon prices depend on the visitor's location and delivery address. The actor pins the display currency to the marketplace's own, but it browses anonymously from outside your address, so taxes or shipping-dependent pricing can differ slightly from a logged-in local shopper's view.

Does it log into Amazon? No. It reads only public pages, by design.

Is it legal to scrape Amazon Best Sellers? The actor collects publicly visible product ranking data and no personal data. Make sure your use complies with Amazon's terms and the laws that apply to you; consult a lawyer if unsure.
