Explore all research → GEO and AEO for publishers: Matching books to reader needs
Reviews show why readers choose a book and how they use it. Connecting those insights with customer demand and ChatGPT’s recommendations helps you decide what to explain in your descriptions, which material to share, and where to publish it so the right readers can discover your books.
FOUNDATIONS How books show up in ChatGPT and AI search
To improve a book’s visibility in ChatGPT and AI search, publishers need to understand what informs an answer and which components they can influence.
RESEARCH Should Book Keywords Be Single Words or Search Phrases?
We conducted a study that found natural reader-search phrases made far better use of limited keyword space than tag-based single-word keywords. Search phrases produce substantially more visibility when searched directly or in expanded search forms.
RESEARCH Nearly half of publisher keywords are a single word
We analyzed 2.4 million keywords across 94,385 books. Single-word keywords make up 44.57% of the total, by far the largest share. A quarter of the books carry no keywords at all. When publishers use the field, they add a median of 26 keywords per book. Effort is not the problem. Shape is.
