Go through all of Amazon’s suggested keywordsGo to Amazon and select Kindle Store – when typing the first word Amazon will automatically suggest keywords that are well searched (see attached image)
For each suggested keyword, analyze the best-seller rank of the first and last book of the first page, because you want to see if there’s demand and if it’s possible for your book to be displayed on the first page. (If the last book’s best seller rank on the first page is less than 50,000, it will be extremely difficult to display your book on the first page. If the first book’s rank is more than 100,000 – there’s lack of demand for the niche).
