The Keywords That Connect a Book With Its Exact Reader
SEO is the work of helping Google understand what your author page or book listing is about, so it surfaces when someone searches for something related. For an author, this means winning the specific searches only you can answer: your topic, your angle, your story. Generic advice like "write quality content" or "use keywords in your title" won't move the needle when you're competing against sites with years of backlinks on the same broad terms — the angle that works is going narrower than everyone else: a specific sub-genre, a specific reader problem, the exact phrase a reader with your book's exact problem types into Google.
How to research a book's micro-niche
Search Reddit and genre-specific forums for the book's topic — the exact phrases people use there beat any keyword tool.
Check Google's autocomplete for the book's core topic to see what people are actually asking.
Compare against Amazon.com: which similar books already rank, and what words do they use in their title and description.
On-page SEO: the non-negotiables
Title and meta description built around the primary keyword, no filler.
An H1 that matches what the person is searching for, not a clever tagline.
Internal links to related content (for example, to the AEO pillar when discussing visibility).
Citing sources, statistics, and direct quotes can boost content visibility by over 40% in generative engines — one more reason to build SEO on a solid base.

On paid tools
Tools like Semrush or Ahrefs help, but they're not required to start: Google's autocomplete, Google Trends, and the communities already discussing your book's topic give you enough to get moving without spending anything.
