How to Research Long-Tail Keywords for a Book's Niche
Short answer: don't chase your book's general topic keyword (the big players already own it) — chase the 4-to-7-word phrase that describes the exact problem your book solves, using the real language of forums and communities, not your own.
Step 1: find where the topic is already discussed
Search Reddit, Facebook groups, and specialized forums related to your book's topic. Don't search for mentions of your book — search for how people describe the problem or question before they know a solution exists.
Step 2: use Google's autocomplete
Type your book's core topic into Google and watch the autocomplete suggestions, plus the "people also ask" section. Those phrases are real searches, not guesses.
Step 3: check Q&As on similar books
On Amazon listings for books similar to yours, check the customer questions section (if it exists) and the reviews — that's where people describe, in their own words, what they were trying to solve.
How to prioritize what you find
Prioritize very specific phrases over broad terms — less volume, but far less competition.
Discard phrases that don't actually match what your book answers, even if they have more searches.
Save the exact phrases as you found them — they're the best raw material for article titles and headings.
Long-tail queries make up a significant share of total Google searches, and typically face less competition than one- or two-word generic keywords — which is why they're the most accessible entry point for a new site.
