Detailed Instructions
Finding BSR (Best Sellers Rank)
- Scroll down to Product Details section (below the book description)
- Look for Best Sellers Rank
- You'll see something like:
#12,847 in Kindle Store - Record the overall number (ignore category-specific ranks for now)
- If multiple formats shown, use the Kindle rank
What BSR means:
- Under 10,000 = Strong seller
- 10,000–50,000 = Solid seller
- 50,000–100,000 = Moderate sales
- Over 100,000 = Slow seller
Finding Prices
- Look at the right side of the product page
- You'll see format options: Kindle, Paperback, Hardcover, Audiobook
- Click each format to see its price
- Record Kindle and Paperback at minimum
- Note if any format shows "FREE" with Kindle Unlimited
Finding Review Count and Rating
- Near the top of the page, under the title
- You'll see stars and a number like: ⭐⭐⭐⭐☆ 4.3 out of 5 stars · 2,847 ratings
- Rating = the number out of 5 (e.g., 4.3)
- Reviews = the total count (e.g., 2,847)
Finding Page Count
- Scroll to Product Details section
- Look for Print length or Pages
- Record the number
Checking Kindle Unlimited Status
Look for any of these indicators:
- "Read for Free" button
- "Kindle Unlimited" badge near the price
- "$0.00" with "Kindle Unlimited" mentioned
- "Free with Kindle Unlimited membership"
Record: Y (yes, in KU) or N (not in KU)
Finding Top Category
- In the BSR section, you'll see category rankings
- Example:
#1 in Personal Productivity/#3 in Study Skills - Record the category where the book ranks highest (lowest number)
- This indicates where the book is most competitive
Tips
- Open in new tabs: Open all competitor URLs in separate tabs for faster data entry
- Use the Kindle page: BSR is often clearer on the Kindle edition page
- Ignore audiobook: Focus on Kindle and print formats
- Note anomalies: If something looks unusual (e.g., BSR of 47 for an obscure book), make a note

5-8 books typically takes 10-15 minutes to complete.
