The encyclopedia for the AI search era.https://geo.wikien-UShttps://geo.wiki/robots-txthttps://geo.wiki/robots-txtrobots.txt is RFC 9309 — a voluntary request, not access control. AI bots honor it per category (training, retrieval, user-triggered), with caveats.Wed, 27 May 2026 00:00:00 GMThttps://geo.wiki/geo-roihttps://geo.wiki/geo-roiUnder generative search the click stops attaching to value. Three currencies × three industry models — a defensible number on AI visibility for the CFO.Wed, 27 May 2026 00:00:00 GMThttps://geo.wiki/playbooks/writing-for-ai-citationhttps://geo.wiki/playbooks/writing-for-ai-citationSeven rewrite recipes for AI citation: self-contained chunks, inverted-pyramid sections, FAQ headings, steps, tables, heading discipline, quotable claims.Wed, 27 May 2026 00:00:00 GMThttps://geo.wiki/ai-search-timelinehttps://geo.wiki/ai-search-timelineA dated chronicle of AI search from the 2022-11-30 ChatGPT launch through Google AI Overviews to today's stabilization era — every row sourced.Tue, 26 May 2026 00:00:00 GMThttps://geo.wiki/playbooks/citabilityhttps://geo.wiki/playbooks/citabilityA passage-level audit of the seven citability signals — does this chunk survive being lifted into an AI answer? Chunk-extraction test, severity-tagged findings.Mon, 25 May 2026 00:00:00 GMThttps://geo.wiki/core-web-vitalshttps://geo.wiki/core-web-vitalsCore Web Vitals (LCP / INP / CLS) is a Google ranking signal, not an AI-engine signal. Direct effect on AI Overviews, bounded elsewhere.Sat, 23 May 2026 00:00:00 GMThttps://geo.wiki/json-ldhttps://geo.wiki/json-ldJSON-LD is the W3C JSON serialization of Schema.org and Google's recommended format. AI chatbots read it as plain text, not as a parsed graph.Sat, 23 May 2026 00:00:00 GMThttps://geo.wiki/multimodal-signalshttps://geo.wiki/multimodal-signalsMultimodal signals decide whether AI engines can read and cite your images, video, audio, and charts. In 2026, the text channel still dominates over pixels.Sat, 23 May 2026 00:00:00 GMThttps://geo.wiki/sitemap-and-indexnowhttps://geo.wiki/sitemap-and-indexnowSitemap.xml and IndexNow are two URL submission protocols. Both affect AI search only via the host index — AIO via Google, Bing Copilot via Bing.Sat, 23 May 2026 00:00:00 GMThttps://geo.wiki/multilingual-geohttps://geo.wiki/multilingual-geoWhen GEO crosses a language boundary, four things vary: source pool, entity binding, chunk citability, trust pool. Source pool is the load-bearing fact.Fri, 22 May 2026 00:00:00 GMThttps://geo.wiki/ai-content-detectionhttps://geo.wiki/ai-content-detectionAI engines don't penalize you for using AI — they penalize low-effort production patterns. Why classifier-based 'AI detection' isn't the lever it's sold as.Thu, 21 May 2026 00:00:00 GMThttps://geo.wiki/playbooks/brand-mention-trackinghttps://geo.wiki/playbooks/brand-mention-trackingBuild a detector — aliases, disambiguation, dedup, sentiment — run it on a frozen prompt set, then derive Mention Frequency, SOV, Answer Inclusion Rate.Wed, 20 May 2026 00:00:00 GMThttps://geo.wiki/brand-mentionshttps://geo.wiki/brand-mentionsAn unlinked brand mention is a load-bearing GEO signal: being named without a link feeds the model's entity prior and compounds into future answers.Tue, 19 May 2026 00:00:00 GMThttps://geo.wiki/entity-recognitionhttps://geo.wiki/entity-recognitionEntity recognition is the join that attaches a mention, citation, or markup assertion to the right known node. Don't resolve and credit leaks or misroutes.Tue, 19 May 2026 00:00:00 GMThttps://geo.wiki/knowledge-graph-presencehttps://geo.wiki/knowledge-graph-presenceA node in Wikipedia, Wikidata, or the Google Knowledge Graph makes AI engines treat you as a known entity — but you can't add yourself; it has to be earned.Tue, 19 May 2026 00:00:00 GMThttps://geo.wiki/llms-txthttps://geo.wiki/llms-txtllms.txt (Answer.AI, 2024) is a curated markdown file naming the pages an LLM should read first. Supply-side adoption real, demand-side unconfirmed.Tue, 19 May 2026 00:00:00 GMThttps://geo.wiki/playbooks/ai-citation-trackinghttps://geo.wiki/playbooks/ai-citation-trackingA repeatable manual + automated workflow to measure how often, how prominently, and on which AI engines you are cited. Sample, verify, normalize, report.Tue, 19 May 2026 00:00:00 GMThttps://geo.wiki/playbooks/geo-audithttps://geo.wiki/playbooks/geo-auditThe full GEO audit method: a 6-layer dependency ladder — access → render → structure → content → off-site authority → outcome — audited bottom-up.Tue, 19 May 2026 00:00:00 GMThttps://geo.wiki/ai-crawlershttps://geo.wiki/ai-crawlersAI crawlers split into three categories — training, retrieval, user-triggered — with opposite access consequences. Per-category access, not per-bot.Mon, 18 May 2026 00:00:00 GMThttps://geo.wiki/e-e-a-thttps://geo.wiki/e-e-a-tE-E-A-T is Google's quality-rater framework, not an algorithmic score. In GEO it's the trust half of grounding — is a retrieved passage's source worth using?Mon, 18 May 2026 00:00:00 GMThttps://geo.wiki/citation-vs-mentionhttps://geo.wiki/citation-vs-mentionAI answers credit you three non-equivalent ways: citation, mention, link. Being grounded on and being credited are decoupled — each needs its own metric.Mon, 18 May 2026 00:00:00 GMThttps://geo.wiki/schema-org-for-aihttps://geo.wiki/schema-org-for-aiSchema.org isn't a ranking or citation signal — it's infrastructure for AI. It makes an entity resolvable, not a passage liftable. Two different jobs.Mon, 18 May 2026 00:00:00 GMThttps://geo.wiki/answer-loophttps://geo.wiki/answer-loopEvery generative engine runs the same four-step loop: query → retrieval → grounding → answer. GEO is per-step intervention — one lever, one failure mode each.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/citabilityhttps://geo.wiki/citabilityCitability is whether your content can be quoted intact in an AI answer — a structural property of the passage itself, not of how trusted the source is.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/generative-enginehttps://geo.wiki/generative-engineA generative engine retrieves sources and synthesizes one written answer with an LLM. The break from search is the output unit — documents vs. composed answer.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/zero-click-searchhttps://geo.wiki/zero-click-searchUsers get the answer on the results page and never click a source. Most Google searches were already zero-click before AI — the precondition for GEO.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/platforms/chatgpt-searchhttps://geo.wiki/platforms/chatgpt-searchChatGPT Search is retrieval-augmented chat: ChatGPT fetches the live web only when the model decides to. OAI-SearchBot — not GPTBot — controls visibility.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/platforms/google-ai-overviewshttps://geo.wiki/platforms/google-ai-overviewsGoogle AI Overviews is the SERP-embedded AI engine: a Search-top summary grounded via query fan-out. Googlebot controls eligibility, not Google-Extended.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/platforms/google-geminihttps://geo.wiki/platforms/google-geminiGemini is Google's retrieval-augmented chat engine: a chat model with a Google-Search grounding tool. Google-Extended is the real control here, not Googlebot.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/platforms/perplexity-aihttps://geo.wiki/platforms/perplexity-aiPerplexity is an answer-engine-native generative engine: live retrieval by default, every answer with numbered citations — the baseline for GEO research.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/papers/aggarwal-geo-benchmark-2024https://geo.wiki/papers/aggarwal-geo-benchmark-2024The KDD 2024 paper that coined Generative Engine Optimization, released GEO-bench and the impression metric, and reported AI-answer visibility lifts up to 40%.Sun, 17 May 2026 00:00:00 GMThttps://geo.wiki/aeo-vs-geohttps://geo.wiki/aeo-vs-geoAEO and GEO are the same discipline under different names — AEO was the Featured-Snippet era; GEO is the term that stuck once generative synthesis took over.Sat, 16 May 2026 00:00:00 GMThttps://geo.wiki/generative-engine-optimizationhttps://geo.wiki/generative-engine-optimizationGenerative Engine Optimization (GEO): how content gets cited in ChatGPT, Perplexity, Google AI Overviews, and Gemini answers — an SEO layer, not a replacement.Sat, 16 May 2026 00:00:00 GMThttps://geo.wiki/llmo-vs-geohttps://geo.wiki/llmo-vs-geoLLMO and GEO are mostly the same discipline. The one truly distinct reading — training-corpus inclusion — is precisely what GEO excludes.Sat, 16 May 2026 00:00:00 GMThttps://geo.wiki/seo-vs-geohttps://geo.wiki/seo-vs-geoSEO and GEO share the plumbing — crawlability, expertise, structure, authority — and split at the finish: a clicked rank vs a cited or mentioned answer.Sat, 16 May 2026 00:00:00 GMThttps://geo.wiki/geo-metricshttps://geo.wiki/geo-metricsThe 10 KPIs that measure GEO — definitions, formulas, SEO equivalents, and how Profound, Otterly, Ahrefs, BrightEdge, and Similarweb each define them.Thu, 14 May 2026 00:00:00 GMT
