Oliver Scharfenberg publishes AI visibility playbook for SEO and GEO

PhDr. Oliver Scharfenberg has released a new guide on how brands can stay visible as AI assistants and AI Overviews reshape search in 2026. The book argues that businesses now need both SEO and Generative Engine Optimization to show up in AI answers, not just search rankings.

Why it matters: - Search is moving from a list of links to a single AI-generated answer. - The shift raises the stakes for brands, publishers and service providers that depend on discovery through search. - The book argues that being ranked is no longer enough if an AI assistant does not mention the brand in its answer.

What happened: - PhDr. Oliver Scharfenberg, chief executive of Syntharis Group, published The AI Visibility SEO & GEO Playbook: Building AI Visibility with Search Engine Optimization (SEO) and Generative Engine Optimization (GEO). - The book focuses on AI visibility and how businesses can stay present in search experiences shaped by generative AI. - The guide is available on Amazon. - More information is available at the author's Amazon page.

The details: - The book says the core question in search has changed from whether a business ranks to whether it appears in the answer an AI assistant gives the user. - By early 2026, roughly 68% of U.S. Google searches ended without a click to any website, up from about 60% two years earlier, according to figures from SparkToro and Similarweb cited in the book. - Google’s AI Overviews increasingly appear above standard search results and often name sources that never reached the first page of organic results. - The book describes Generative Engine Optimization, or GEO, as the discipline of shaping a company’s content, entity signals and third-party sources so AI systems cite and recommend the brand correctly. - GEO is presented as an extension of SEO, not a replacement. - SEO makes content discoverable, while GEO is meant to make content usable by machines and tied to a recognized brand. - Scharfenberg says ranking first no longer guarantees visibility if a brand is missing from the AI answer. - Scharfenberg says users have shifted from scrolling through links to reading a single answer that cites only a few sources. - The book cites a controlled study showing that adding citations from reliable sources, credible quotations and relevant statistics raised visibility inside generative answers by up to about 40%, while keyword stuffing had little effect. - The book says the best move in an AI answer is to be the clearest and most credible statement of a point. - The playbook introduces a pre-publication 5C Test covering whether a page is clear, credible, citable, consistent and connected. - The book uses entity optimization to help search and AI systems recognize a company as a distinct, trustworthy entity. - One chapter focuses on E-E-A-T, the experience, expertise, authoritativeness and trust signals that influence what sources a machine quotes. - The book frames visibility around three measures: presence, trust and influence. - Scharfenberg argues that influence is a metric companies often fail to measure. - The book spans 14 chapters. - The chapters cover search in 2026, GEO strategy, entity optimization, reputation management and a 12-month roadmap that combines SEO and GEO into one workflow. - The book includes case studies for 10 business types, including a local service provider, a B2B consultancy, a SaaS company, a healthcare provider, a hotel, a university and a financial services firm. - The appendices include templates and worksheets, a glossary, 50 prompts for monitoring how AI tools describe a brand and 100 AI visibility prompts for auditing a company’s presence.

Between the lines: - The book reflects a broader industry push to adapt SEO to answer engines and generative search. - The emphasis on citations, entity signals and third-party credibility suggests that AI visibility depends as much on reputation and structure as on keywords. - The study cited in the book points to a practical shift: machine-readable trust signals may matter more than repetitive keyword tactics.

What's next: - Businesses that rely on search traffic may need to treat SEO and GEO as a combined workflow. - The book’s roadmap and prompts are positioned as tools for brands to audit how they appear inside AI-generated answers. - Scharfenberg’s framework suggests that future visibility work will focus on being quoted, recognized and recommended by AI systems, not just indexed by search engines.
