Research

Studies on how readers find books in Amazon search and AI tools. Read the findings, examine the methods, and explore the questions publishers ask.

  1. AI discovery

    Publishers are rewriting book pages as FAQs. Under 1% of the pages ChatGPT cited had one that matched.

    We collected 27,702 ChatGPT answers to reader requests and read the publisher pages behind them. Two pages in a hundred had an FAQ at all, and on the pages that did, the answer’s wording usually matched a passage somewhere else in the text. Put those together and FAQs account for less than 1% of answers returned by ChatGPT.

    Under 1% of cited publisher pages had an FAQ that matched ChatGPT’s answer

    Of every 100 publisher pages ChatGPT cited, 2 had an FAQ and under 1 had an FAQ that matched the answer’s wording. Based on 1,718 publisher pages cited in 27,702 ChatGPT answers.

  2. AI discovery

    Where AI book recommendations come from

    Publisher websites appeared in three quarters of the ChatGPT source lists we examined. Our study of 27,702 answers to reader requests looks beyond the familiar website names to the book descriptions, reading guides and other pages that surfaced, and what publishers can learn from them.

    75.6% of source lists for 27,702 ChatGPT answers included a publisher website

    Source-list appearances in 27,702 answers: retailer (e.g. Barnes & Noble, Kobo) 81.0%; reader community (e.g. Reddit, Goodreads) 77.6%; editorial and review (e.g. Book Riot, Kirkus Reviews) 77.1%; publisher 75.6%; book summary or discovery service 52.9%; reference 39.0%; library 17.0%; institutional 11.5%.

  3. AI discovery

    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.

    Four reader requests, each asked in ChatGPT three times without naming the book or its author. Explaining the main types of dementia plainly, and what each means for family care: The Dementia Caregiver was named in all three answers, first in two. A short starter for the first week after a diagnosis: not named; ChatGPT recommended other introductory guides and parts of broader references. Portable checklists for daily care: not named; it recommended books with checklists and forms, the same two books in all three answers. Questions to take to appointments: not named; it recommended question-focused books and free appointment guides.

  4. AI discovery

    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.

    A language model combines knowledge learned during training with information found now and the conversation to generate an answer for the user.
