The Best FREE Keyword Research Tool For Amazon KDP

About this video

(Summarized from the Bengali-language transcript.) The creator introduces a free Chrome extension from Coauthor, his own Amazon KDP software, positioned as an alternative to paid keyword research tools with no usage limit. In Amazon search results it surfaces each book’s Best Sellers Rank without opening the product page, and from BSR, page count and format (paperback vs hardcover) estimates daily sales and daily royalty income, with an example the creator claims reaches up to $1,000 a day. It also expands Amazon search suggestions with added words before, after and inside a typed term, plus search volume, to generate more keyword ideas. A highlighted feature is BSR Trend, showing 1-month to all-time history: a spooky Halloween coloring book spikes every October and a vision board book spikes in January, so the creator advises launching about two months early to collect reviews and rank before the peak, and using the trend to separate seasonal topics from evergreen ones. An ‘Analyze Book’ button has Coauthor read hundreds of reviews and suggest three differentiated positioning ideas, such as offering more value, niching to a specific audience, or focusing on a narrower angle. Paid Coauthor features are then previewed, including reverse ASIN lookup, Niche Hunter filtering, and book creation tools; the free extension covers research and positioning, while continuing the guided book flow requires a paid book credit.

Key takeaways

• Use BSR shown directly in search results to estimate a book’s daily sales and royalties without opening each listing
• Expand a seed keyword with words before, after and inside it, plus search volume, to find more keyword ideas for free
• Check BSR Trend over months and years to spot seasonality, e.g. Halloween books in October and vision board books in January
• Launch seasonal books about two months before their peak to gather reviews and rank on page one in time
• Differentiate instead of copying: add more value, target a specific underserved audience, or take a narrower topical angle
