40% of Amazon sellers make between $1,000 and $25,000 per month, while super sellers earn over $100,000 per month. The key difference? Targeting the best-selling items, which Amazon publicly shares on its “Best Seller” lists. These pages are a goldmine of information, revealing consumer trends, hot products, and market opportunities. Let’s dive into “how to scrape Amazon Best Sellers” and leverage this data for better decision-making.
What is the Amazon Best Seller Rank?
Amazon ranks its best-selling products on its Best Seller pages, known as the Amazon Best Sellers Rank (BSR). While Amazon does not disclose the exact formula for ranking, it is widely accepted that sales volume is the primary factor, with recent sales carrying more weight than older ones. The list updates hourly, ensuring the most up-to-date snapshot of consumer demand.
Amazon categorizes these rankings into over 30 main categories, each with multiple subcategories—totaling around 25,000 categories. The algorithm also includes predictive factors to analyze potential future sales. These lists provide valuable insights, such as:
- Trending Products: Identify emerging trends before they peak.
- Competitive Analysis: See what your competitors are selling and how they’re performing.
- Market Research: Understand consumer preferences and demand shifts.
- Product Development: Spot market gaps and discover potential new product opportunities.

With about 25,000 categories and rankings that vary across Amazon’s 20+ domains (amazon.com, amazon.co.uk, amazon.ca, etc.), manually collecting this data is impractical. Additionally, since the rankings update hourly, staying on top of these trends requires automation—this is where scraping APIs come in.

What is an Amazon Best Sellers Scraper?
An Amazon Best Sellers Scraper is a tool or script designed to automatically extract data from Amazon’s Best Sellers pages. These scrapers can be custom-built or utilize pre-built APIs, like Traject Data’s Amazon Rainforest API, to streamline the process.
The Legality and Challenges of Scraping Amazon
Now, let’s address the elephant in the room: is it legal to scrape Amazon? The answer is nuanced.
- However, the legality of web scraping is a complex legal area and depends on how the extracted data is used.
- Amazon employs various anti-scraping measures to detect and block automated scraping activities.
How Does Amazon Prevent Scraping?
Amazon implements several techniques to block scraping, including:
- IP Address Blocking: Blocking IPs that send too many requests.
- CAPTCHAs: Requiring users to verify they are human.
- Rate Limiting: Restricting the number of requests per IP address.
- User-Agent Analysis: Identifying bots through user-agent strings.
- Honeypot Traps: Inserting hidden elements that only bots can see.
Due to these challenges, maintaining a manual scraping script is difficult and costly.
