Generative Engine Optimization vs Ultimate Guide to Link Building: AI visibility or link prospecting

Quick answer

These books mostly do different jobs, with one point of contact. Ross Hudgens’ Generative Engine Optimization (Wiley, 2026) is a guide to getting brands mentioned and cited in AI answer engines, for practitioners and marketing leaders building a GEO program. Garrett French and Eric Ward’s Ultimate Guide to Link Building (2nd edition, 2020) is a specialist book on finding link opportunities and building an outreach prospect list. If your job is AI visibility, read Hudgens; if your bottleneck is finding sites that might link to you, read French and Ward.

What each book is about

Generative Engine Optimization: The Definitive Guide to AI SEO is Hudgens’ first edition, listed by Wiley at 320 pages (ebook September 2026, hardcover October 2026). Hudgens founded the content and SEO agency Siege Media. Wiley names SEO practitioners, marketing leaders at technology companies, CMOs and content marketers as readers. The nine chapters cover how GEO differs from SEO, measuring visibility, sentiment and position, how generative engines work (query fan-out, retrieval, reranking and chunking), GEO strategy including digital PR, content structure and schema markup, digital and performance PR, case studies (Zapier, Bluevine and Siege Media), building a GEO-first organization, and agents and tool use via MCP. Official contents (PDF).

Ultimate Guide to Link Building is by Garrett French and Eric Ward. Entrepreneur Press lists the second edition for January 2020, with ISBN 9781599186481 for the paperback. Publisher catalogue, page 31. An authorized excerpt begins with terms that define a market and uses them to locate different kinds of opportunities, such as expert interviews, resource curators and sites accepting relevant contributions. It also discusses finding existing interviews and developing a new group interview from that research. Second-edition excerpt.

Where they differ

Subject. Hudgens covers AI answer engines such as ChatGPT, Gemini, Perplexity and Claude: how they select content, how to measure visibility, and how to plan content and PR for them. French and Ward cover one traditional SEO discipline, link prospecting.

Where they meet. Both involve getting other sites and publications to reference you. Hudgens treats digital and performance PR as part of a GEO program. French and Ward give a whole book to the groundwork of outreach: discovering the people and publications in a market and what might belong there. A reader planning PR for AI answers may find the prospecting method a useful complement, though the 2020 book does not address AI answers.

Scope and reader. Hudgens is broad, covering strategy, content, PR, case studies and team structure. French and Ward are narrow and practical, for readers who already know SEO basics.

Era and interests. French and Ward’s edition is from January 2020; check any link tactic against Google’s current link spam policy. Hudgens is a 2026 snapshot of a fast-moving field. His Chapter 3 is written by Josh Blyskal of Profound, which sells AI-visibility software, and one case study is Siege Media, both disclosed in the contents.

A third option for a step-by-step beginner start

Hudgens already covers AI search for teams. A different reader, a business owner or marketer who wants a step-by-step start in AI search, might look at AI SEO for Dummies, a 2026 Wiley For Dummies title on visibility in AI-powered search, including AEO and GEO. Wiley names business owners, marketers and SEO professionals as its readers, and a free companion toolkit includes a quickstart checklist, a First 30 Days worksheet and trackers, with no email required. It is an alternative for that reader, not a replacement for Hudgens, and it is not a link-building book.
