Amazon Ratings Scraper

A memory-efficient Apify Actor that scrapes product ratings, review counts, and star distribution from Amazon using CheerioCrawler (no browser needed).

Features

• Low Memory: Runs on 256 MB — uses ~4× less memory than browser-based scrapers
• Low Cost: ~0.25 CU per 100 products (vs ~1–2 CU with Playwright)
• Flexible Input: Accepts ASINs, product URLs, or a mix of both
• Cross-Marketplace: Mix .com and .in URLs (and 18 other domains) in a single run — marketplace is auto-detected from each URL
• Smart Fallback: If star distribution isn't found on the product page, automatically tries the reviews page
• Session Rotation: Built-in session pool to avoid blocks
• Error Reporting: Failed requests are logged in the dataset with error details

Output Format

Each product produces a JSON object like this:

{
    "asin": "B0BN93GLDN",
    "title": "Apple iPhone 14 Pro Max, 256GB, Deep Purple - Unlocked",
    "url": "https://www.amazon.com/dp/B0BN93GLDN",
    "marketplace": "www.amazon.com",
    "overallRating": 4.6,
    "totalRatingsCount": 12847,
    "starDistribution": {
        "5_star": 76,
        "4_star": 12,
        "3_star": 5,
        "2_star": 3,
        "1_star": 4
    },
    "scrapedAt": "2026-03-22T10:30:00.000Z"
}

Input Examples

Using ASINs (uses default marketplace)

{
    "inputs": ["B0BN93GLDN", "B09V3KXJPB", "B0DLHBKTRN"],
    "marketplace": "www.amazon.com"
}

Using URLs (marketplace auto-detected per URL)

{
    "inputs": [
        "https://www.amazon.com/dp/B0BN93GLDN",
        "https://www.amazon.in/Some-Product/dp/B09V3KXJPB/ref=sr_1_1"
    ]
}

In the above example, the first product scrapes from .com and the second from .in — automatically.

Mixed ASINs + URLs from different marketplaces

{
    "inputs": [
        "B0BN93GLDN",
        "https://www.amazon.com/dp/B09V3KXJPB",
        "https://www.amazon.in/dp/B0DJYHM2V7"
    ],
    "marketplace": "www.amazon.com",
    "maxConcurrency": 5
}

Here, B0BN93GLDN (plain ASIN) uses the fallback marketplace .com, while the two URLs each use their own detected domain.

Cost Estimation

Costs exclude proxy usage. Residential proxies are recommended for Amazon.

Local Development

# Install dependencies
npm install

# Create input file
mkdir -p storage/key_value_stores/default
echo '{"inputs":["B0BN93GLDN"],"marketplace":"www.amazon.com"}' > storage/key_value_stores/default/INPUT.json

# Run locally (without proxy — may get blocked)
npm start

Deploying to Apify

# Install Apify CLI
npm install -g apify-cli

# Login
apify login

# Push to Apify platform
apify push

Tips for Best Results

1. Use Residential Proxies — Amazon aggressively blocks datacenter IPs
2. Keep concurrency low (3–5) — saves memory and reduces block rate
3. Set marketplace correctly — Amazon shows different data per region
4. Run during off-peak hours — lower chance of CAPTCHAs
