Tracking Amazon Product Category Shifts with SellerMagnetAPI

In the dynamic world of Amazon, product categories are not static. They shift, evolve, and sometimes, completely transform. For Amazon businesses and market analysts, staying ahead of these changes is crucial for competitive analysis, inventory management, and effective market research. This is where the SellerMagnetAPI (https://sellermagnet-api.com) proves invaluable. Our enterprise-grade Amazon data API provides the tools necessary to monitor and analyze these category shifts, empowering you to make data-driven decisions.

Why Track Amazon Product Category Shifts?

Understanding how product categories change over time can unlock significant advantages:

  • Competitive Analysis: Identify emerging competitors and track their movements within different categories.
  • Inventory Management: Optimize your inventory based on category trends and demand fluctuations.
  • Market Research: Gain insights into evolving consumer preferences and identify new market opportunities.
  • SEO Optimization: Improve product discoverability by aligning your listings with the most relevant and trending categories.

How SellerMagnetAPI Helps You Track Category Shifts

SellerMagnetAPI offers several endpoints that can be leveraged to track and analyze Amazon product category shifts. Here’s how you can use them:

1. Monitoring Product Statistics Over Time

The Amazon Product Statistics endpoint (/amazon-product-statistics) allows you to retrieve detailed statistics for an Amazon product, including its sales rank and review counts. By tracking these metrics over time, you can infer changes in the product's category placement and performance.

Here’s an example of how to use the API to get product statistics:


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-statistics?asin=B08N5WRWNW&marketplaceId=A1PA6795UKMFR9&api_key=YOUR_API_KEY'

Example Response:


{
  "success": true,
  "data": {
    "asin": "B08N5WRWNW",
    "amazonPrice": 2999,
    "bestSellerRank": 125,
    "buyBoxPrice": 3200,
    "buyBoxFulfillment": "FBA",
    "buyBoxSellerIdHistory": [
      ["2024-01-01T00:00:00Z", "A123BC456DEFGH"]
    ],
    "salesRankHistory": [
      ["2024-01-01T00:00:00Z", 150],
      ["2024-01-02T00:00:00Z", 125]
    ],
    "trackingSince": "2023-12-01",
        "graphs": null,
        "metadata": {
          "category": "Electronics",
          "lastUpdated": "2024-01-02T12:00:00Z"
        }
  }
}

By scheduling regular calls to this endpoint using our DataPipeline feature, you can build a historical record of a product's category and sales rank. Significant changes in these metrics may indicate a category shift.

2. Identifying Category Changes with Product Lookup

The Amazon Product Lookup endpoint (/amazon-product-lookup) provides detailed product information, including its current categories. Comparing this information over time reveals if a product has been moved to a different category.

Here’s how to use the API:


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-lookup?asin=B08N5WRWNW&marketplaceId=A1PA6795UKMFR9&api_key=YOUR_API_KEY'

Example Response:


{
  "success": true,
  "data": {
    "productInfo": {
      "asin": "B08N5WRWNW",
      "title": "Example Product",
      "categories": {
        "rootCategory": {
          "id": "12345",
          "name": "Electronics",
          "url": "https://www.amazon.com/electronics"
        },
        "bestsellerCategory": [
          {
            "id": "67890",
            "name": "Cell Phones & Accessories",
            "url": "https://www.amazon.com/cell-phones"
          }
        ]
      },
      "details": {
        "ASIN": "B08N5WRWNW",
        "Manufacturer": "Example Manufacturer"
      },
       "additionalDetails": {
        "ASIN": "B08N5WRWNW",
        "Item Weight": "1 pounds"
      },
      "bestsellerRanks": {
        "main_category": {
          "name": "Electronics",
          "rank": 100
        },
        "subcategory": {
          "name": "Cell Phones & Accessories",
          "rank": 10
        }
      },
            "buyBoxInfo": {
                "currencyCode": "USD",
                "currencyName": "United States Dollar",
                "currencySymbol": "$",
                "price": 29.99,
                "sellerId": "A1234567890"
            },
      "images": ["https://example.com/image.jpg"],
      "link": "https://www.amazon.com/dp/B08N5WRWNW",
      "marketplaceId": "A1PA6795UKMFR9",
            "reviews": {
                "averageRating": 4.5,
                "reviewSummary": "4.5 out of 5 stars",
                "totalReviews": 1000
            },
      "bulletPoints": ["High Quality", "Easy to Use"],
            "description": ["This is an example product description."],
      "variations": [],
      "videos": [],
      "hasAPlusContent": false,
      "listedSinceDate": "2020-11-15"
    }
  }
}

By comparing the categories and bestsellerRanks fields over time, you can detect when a product's primary category or subcategory changes.

3. Monitoring Bestseller Lists for Category-Specific Insights

The Amazon Bestsellers endpoint (/amazon-bestsellers) allows you to fetch the top-selling products within a specific category. Monitoring these lists regularly can reveal shifts in category popularity and emerging product trends.

Example API usage:


curl --location --request GET 'https://sellermagnet-api.com/amazon-bestsellers?category_id=electronics&marketplaceId=A1PA6795UKMFR9&api_key=YOUR_API_KEY'

Example Response:


{
  "category": "electronics",
  "bestsellers": [
    {
      "asin": "B08N5WRWNW",
      "rank": 1,
      "title": "Example Product 1"
    },
    {
      "asin": "B07X1XYZ23",
      "rank": 2,
      "title": "Example Product 2"
    }
  ]
}

Changes in the ASINs appearing in the bestseller list, or significant shifts in their rankings, can indicate a category is undergoing change.

4. Leverage Amazon Product Offers

By tracking the Amazon Product Offers over time and look at the Buy Box changes. Changes could signify category shifts or changes in customer preferences.


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-offers?asin=B0CL61F39H&marketplaceId=ATVPDKIKX0DER&api_key=YOUR_API_KEY'

{
    "data": {

        },
        "marketplaceId": "ATVPDKIKX0DER",
        "offers": [
            {
                "condition": "New",

                "fulfillmentType": "FBA",
                "inventory": 30,
                "positivePercentage": 0,

                "shippingPrice": 0,
                "totalPrice": 409.99,
                "totalReviews": 6892
            }
        ],
        "productLink": "https://www.amazon.com/dp/B0CL61F39H",
        "productMainImage": "https://m.media-amazon.com/images/I/31kTNmpm6vL.jpg",
        "productTitle": "PlayStation®5 console (slim)"
    },
    "success": true
}

Practical Use Cases

  • Scenario 1: A product initially categorized under “Home Audio Speakers” starts appearing in the “Smart Speakers” bestseller list. This suggests a shift towards smart home integration, prompting a business to update its product descriptions and marketing strategy accordingly.
  • Scenario 2: A brand monitoring product category shifts using the Amazon Product Statistics endpoint and notices that ASIN B08N5WRWNW is consistently improving its bestseller rank. Further investigation using the Amazon Product Lookup endpoint reveals that the product has been re-categorized into a more popular subcategory.
