Where ad keyword ideas come from
Good book-ad keywords usually come from the book's promise, genre, comparable authors, comparable titles, audience problems, and reader language. Kindlefish blends those angles with marketplace signals to build a starting list.
Match type matters
Broad, phrase, and exact match keywords behave differently. Kindlefish separates keyword ideas by intended use so authors can start more deliberately and avoid treating every term as the same kind of target.
Bid ranges are only starting context
Real auction prices depend on account history, placement, conversion rate, budget, seasonality, and competition. Kindlefish treats bid guidance as a starting band to test, not a target or profitability promise.
Questions authors ask
Can Kindlefish manage my Amazon Ads campaign?
No. Kindlefish provides keyword research and starting context. Campaign setup, budget decisions, and optimization remain inside your Amazon Ads account.
Are KDP backend keywords and ad keywords the same?
They can overlap, but they have different jobs. Backend keywords support discoverability; ad keywords control paid targeting and spend.
