Each engine reads live web pages, synthesizes an answer, and names a few sources, so the goal is to be one of those named sources. This page is the per-engine view and is part of [[seo/llm-seo-best-practices]], the pillar for the wider discipline of being citable by AI systems. For the off-Google answer engines as a technique, see [[seo/answer-engine-optimization]]; for the Google feature specifically, see [[seo/ai-overviews]]. ## Know how each engine sources its answers The four major AI search products retrieve and cite differently, so optimize for the mechanism, not a generic "AI." - Perplexity runs its own live retrieval over a web index and cites inline. It fetches with `PerplexityBot` for indexing and `Perplexity-User` for user-initiated lookups. - Google AI Overviews draws on the Google index and Gemini, so it inherits classic ranking inputs: `Googlebot` access and organic rank still gate inclusion, while `Google-Extended` governs generative use. - ChatGPT Search retrieves live results and cites them, fetching with `OAI-SearchBot` for indexing and `ChatGPT-User` for user-initiated fetches. `GPTBot` is training only. - Bing Copilot builds answers from the Bing index, so `Bingbot` crawlability and Bing ranking carry straight over. ## Allow every engine's crawler or you cannot be cited A page an engine cannot fetch cannot be quoted. Allow each engine's search and user-fetch agents in `robots.txt`, even if you disallow the training-only agents. Block `PerplexityBot` and you vanish from Perplexity; block `Googlebot` and you lose AI Overviews. See the full token catalog in [[cheatsheets/ai-crawlers]] and [[seo/discoverability-files]]. ## Win the citation with an extractable answer Each engine lifts a discrete chunk that answers the query, so lead every page and section with a direct, self-contained answer it can quote verbatim. The extractable-claim pattern is the single highest-impact move and is the same across all four engines. See [[seo/answer-first-content]]. ## Be the entity each engine resolves AI search engines disambiguate using named entities and their identifiers. Name the primary entity in the title, H1, and first sentence, and ground it with `sameAs` markup so the engine maps the page to the right concept. The markup and entity work live in [[seo/structured-data-for-ai-crawlers]]; the author and trust signals are in [[seo/e-e-a-t]]. ## Monitor per-engine inclusion No engine reports citations cleanly in Search Console, so track inclusion per product. - Run a fixed prompt list weekly through Perplexity, ChatGPT Search, and Bing Copilot; record which prompts cite the domain. - For AI Overviews, run manual SERP checks on a fixed query list from a clean session. - Filter server logs by `PerplexityBot`, `OAI-SearchBot`, `Google-Extended`, and `Bingbot`; a fetch spike usually precedes a citation by 24 to 72 hours. Treat the user-agent log as the leading indicator and the manual check as the confirmation. ## Pitfalls - Blocking an engine's crawler in `robots.txt` while wanting its citations. Allowing the fetcher is the prerequisite. - Optimizing only for Google AI Overviews and ignoring Perplexity, ChatGPT Search, and Copilot, which source answers from different indexes. - Treating AI search as separate from SEO. AI Overviews and Bing Copilot still ride classic ranking, so the technical and content foundation carries over. - Stuffing FAQ schema to trigger an answer block. The classifier ignores markup the visible content does not back.
