The SEO, GEO, AIO, AEO, AISEO & AI Search Optimization Blog
As AI search fundamentally shifts how consumers discover information, Generative Engine Optimization is rapidly evolving from a novel concept into an essential business practice. To succeed, brands must move beyond simply monitoring their AI visibility to actively building the workflows, benchmarks, and tools needed to operationalize it.
Clicks are disappearing and rankings no longer predict who gets cited. Here are the AI search performance metrics that survive contact with real data, including a number most tools never show you: how often AI names a brand without citing it.
Google rolled out Gemini 3.6 Flash to everyone in the Gemini app. The app looks the same, but the model writing the answers is new, and that can move which brands get named.
ChatGPT answers most prompts without searching the web, and when AI engines do search, each retrieves differently. A brand-level walk through the RAG pipeline: where brands drop out, and what moves each stage.
AI engines assemble recommendation shortlists from listicles, review sites, YouTube, and Reddit, not from brand domains. The evidence for treating earned media as the core AI search strategy.
Brands are told to invest in GEO, then asked to prove it with a measurement stack that cannot see most AI search exposure. We walk through what GA4, Search Console, and server logs actually capture, why the variance studies invalidate single-scan audits, and what an honest share-of-voice method looks like.
Most GEO advice is about content. But a surprising share of the sites we audit lose AI visibility before a word is judged, because a crawler was blocked or the page rendered empty. Here is the plumbing checklist.
AI search engines do not cite pages, they cite passages that survive a five-stage pipeline. Google's fan-out, Perplexity's span-level retrieval, ChatGPT's 18% search rate: here is how production RAG actually decides citations, and what you can influence at each stage.
Brands keep rewriting their pages to sound more confident, more authoritative, more persuasive for AI engines. The data tells a harsher story: 82% of AI citations go to earned media, your own site captures 2.9% of citations on unbranded queries, and the best-tested style tweak is worth a third of what adding verifiable statistics is worth. Here is what the evidence actually supports.
Every AI visibility tool sells a score. Almost nobody checks whether their score predicts anything. We regressed 22 weeks of observed AI citations against the audit scores brands held before those answers were generated. Here is what survived honest validation, engine by engine, including the parts that did not flatter us.
