Frequently asked questions
Ten factual answers with explicit limits. Missing public evidence remains missing evidence, not an invitation to guess.
01 What does “LLM optimization” mean?
The term is ambiguous. It may refer to website visibility in AI answers, LLM application optimization, model optimization, evaluation, or agent orchestration. On this site, LLMO, GEO and AEO primarily cover content visibility.
View the five-discipline map →02 Does GEO replace SEO?
No. Google says established SEO fundamentals remain valid for AI features in Search. Crawling, indexing, helpful content, internal links and page experience still matter. GEO adds measurement and citability questions without replacing the SEO foundation.
Compare SEO, GEO and AEO →03 Should every AI bot be blocked?
Decide agent by agent and purpose by purpose. Operators document separate agents for search, user-triggered access and model improvement. robots.txt expresses a crawl preference, but alone it proves neither effective access nor the final use of content.
Review documented agents →04 How can ChatGPT or Perplexity presence be measured?
Use a stable prompt panel, fixed language and locale, repeated runs and a public rule for classifying mentions, citations and accuracy. Results remain a dated sample, not an exhaustive measurement of every user.
Generate a local prompt panel →05 How long does it take to obtain a result?
No general deadline is defensible. It depends on crawling, indexing, the source used by the engine, the query and existing authority. A modified date does not prove that an engine retrieved or selected the content.
06 Should a site publish llms.txt?
Google Search says it ignores llms.txt. The file replaces neither robots.txt, sitemaps nor indexable HTML. Publish it only as an editorial index for an identified compatible tool or agent, without claiming an undocumented ranking effect.
Read the documented status of llms.txt →07 Does Schema.org automatically improve AI citations?
No. Google says no special Schema.org markup is required for its AI features. Structured data can clarify entities and make a page eligible for specific features when their policies are met, but it does not guarantee a citation.
08 Do engines prefer long content?
No universal length is documented. Depth should serve the question. A long page remains useful when its sections are distinct, accessible and sourced. Adding words without new information dilutes the answer and does not prove authority.
09 Is a JavaScript-rendered site invisible?
Not necessarily. Rendering capability varies by crawler and product. Reduce dependence on it by serving critical content, links and metadata in the initial HTML, then test the HTTP response and rendering with appropriate tools.
10 Can anyone guarantee a citation or first place?
No. Engines, corpora, queries and answers change, and selection systems are not fully public. A provider can guarantee a protocol, technical controls, a measurement calendar and honest reporting, not a citation.
