Interpreting the Data:

  • Sales Rank: A lower sales rank generally indicates higher sales. Track the Sales Rank History over time to understand sales trends.
  • Review Count: A high and increasing review count often correlates with strong sales.
  • Buy Box Price: The Buy Box price reflects the price at which most sales occur. Monitoring this price helps in understanding revenue potential.
  • Monthly sold History: Using the Amazon Product Statistics, you can also retrive graphs, that shows month sold history.

2. Calculating Estimated Sales

To estimate sales, correlate the sales rank with known sales data for similar products. While Amazon keeps exact sales figures private, you can use the following approach:

  • Gather Historical Data: Use SellerMagnet’s API to collect sales rank history over a period (e.g., 30 days).
  • Categorize Products: Ensure you're comparing products within the same category, accessible through Amazon Product Lookup.
  • Cross-Reference with Public Data: While rare, some companies may release sales figures which can be used to create benchmarks.

3. Utilizing Amazon Product Search Estimated Sells

The Amazon Product Search Estimated Sells provides an estimation of monthly sales for the ASIN.

Endpoint: /amazon-product-search-estimated-sells

Method: GET

Description: Retrieve estimated sales data for an Amazon product by ASIN.

Parameters:

  • asin (text, required): Product ASIN (e.g., "B08N5WRWNW")
  • marketplaceId (text, required): Marketplace ID (e.g., "A1PA6795UKMFR9")
  • api_key (text, required): Your API key

Example Request:


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

Example Response:


{
  "success": true,
  "data": {
    "asin": "B08N5WRWNW",
    "estimated_monthly_sales": 121
