SEO For Dummies vs Generative Engine Optimization: a first SEO book or a GEO program guide

Quick answer

These books differ in both subject and reader. Peter Kent’s SEO For Dummies (7th edition, 2020) is a broad beginner introduction to traditional SEO for website owners. Ross Hudgens’ Generative Engine Optimization (Wiley, 2026) is about getting brands mentioned and cited in AI answer engines, written for practitioners and marketing leaders building a GEO program. If you are learning how websites get found in search, read Kent; if your team is being asked to win in AI answers, read Hudgens.

What each book is about

SEO For Dummies is Peter Kent’s introduction in Wiley’s For Dummies series. His author page identifies the seventh edition, released in 2020, and lists resources chapter by chapter. The chapters start with search engines, search results and planning, move through keyword selection, page creation, speed, mobile design and structured data, then cover content, local search, indexing, links, images and video. Earlier editions used the longer title Search Engine Optimization For Dummies. Author’s edition page.

Generative Engine Optimization: The Definitive Guide to AI SEO is Ross Hudgens’ first edition, listed by Wiley at 320 pages (ebook September 2026, hardcover October 2026). 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 retrieve and rerank content, GEO strategy, content structure and schema markup (JSON-LD), 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).

Where they differ

Subject. Kent maps the traditional jobs of SEO: keywords, pages, speed, mobile design, indexing and links. Hudgens is about AI answers: prompt sources, brand positioning, retrieval and citation. His first chapter separates GEO from SEO, which describes how these two books relate.

Reader. Kent writes for website owners starting out. Hudgens writes for people running programs, with chapters on digital PR and on building a GEO team, including roles and career paths.

Era. Kent’s edition predates ChatGPT-era AI search, so its tool and platform instructions should be checked against current documentation such as Google’s SEO Starter Guide. Hudgens’ book is a 2026 title with AI search as its whole subject.

Commercial interests. Chapter 3 of Hudgens’ book is written by Josh Blyskal of Profound, which sells AI-visibility software, and one case study is Siege Media, Hudgens’ own agency. Both are disclosed in the contents. Keep them in mind when weighing tool or agency recommendations.

A third option for a step-by-step AI-search start

There is a gap between these two books: a beginner who wants to learn AI search, not traditional SEO, and is not running a team program. That reader might look at AI SEO for Dummies, a 2026 title in the same Wiley For Dummies series as Kent’s book, covering visibility in AI-powered search, including AEO and GEO, step by step. 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, share-of-voice and citation trackers and report templates, with no email required. For teams building a GEO program, Hudgens remains the closer fit.
