Practical guides on AI search visibility, GEO, and how B2B companies can show up when buyers ask ChatGPT, Perplexity, and Google AI Overviews.
What a GEO agency actually does (measure Share of Model, restructure content, build off-site consensus), how GEO differs from SEO, what to look for when hiring one, and what it costs at market.
Agency GuideEight credible GEO partners, from enterprise relevance engineering to founder-led Share of Model measurement, with honest strengths, who each fits, and a transparent methodology note.
Share of ModelWrite 10-20 golden prompts, run each 3x per engine with live web search, count mentions, compute Share of Model, and freeze the prompt set. The 35% category-leadership threshold and why per-engine variance is signal.
Engine MechanicsOnly ~11% of citations overlap between AI platforms. ChatGPT is Wikipedia-heavy and brand-shy, Perplexity is Reddit-heavy and brand-friendly, and Google AI Overviews now runs query fan-out. The mechanics, per engine.
Freshness EconomicsRoughly 50% of AI-cited content is under 13 weeks old, and new content enters citation pools in 3-5 business days. Why one-time optimization fades and publishing velocity is now a ranking lever.
AI Search EvidenceMonitoring of 500M+ AI bot visits found only 408 llms.txt fetches. Google won't support it, and 8 of 9 sites saw no traffic change. The evidence, and what drives AI citations instead.
Share of Model68% of Google searches end without a click. Share of Model measures how often AI recommends your brand vs. competitors across ChatGPT, Perplexity, and Google AI Overviews, and it replaces every ranking report.
AI Search VisibilityThe two layers of a real audit: a live Share of Model measurement plus a four-channel infrastructure score. What gets checked, how grading works, and why the median B2B company scores 38 of 100.
GEO for ManufacturingOver 70% of B2B technical buyers now use AI during vendor research. HTML spec tables, Product schema, extractable answers, and third-party list placement: the manufacturer playbook.
GEO for Healthcare73% of patients research online before choosing a provider, and they increasingly ask AI first. Physician schema, condition pages, and the directory profiles AI engines actually cite.
