Guide · AEO Strategy
AEO in 2026 is no longer about ranking — it's about being the answer SearchGPT, Gemini, Perplexity, and Google AI Overviews lift into their responses. This guide is the practical playbook: what to change on-page, in your schema, and in your authority signals so AI engines pick your content over a competitor's.
Three things changed how answer engines pick sources this year: (1) AI Overviews now serve over a third of informational queries, (2) ChatGPT search began surfacing real-time citations with referral links, and (3) every major LLM crawler now respects llms.txt. Pages that ignore these shifts keep ranking — and stop being read.
Both engines extract answers from the first 60–80 words and use schema to disambiguate intent. The minimum viable structure:
Article + FAQPage schema, validated via Schema.org's validator.Speakable markup to the answer paragraph for voice surfaces.LLMs cite passages that are quotable: dense with named entities, statistics, dates, and proper nouns. Generic prose gets paraphrased without attribution. Specific prose gets a link.
A public /llms.txt at your domain root tells LLM crawlers which pages to read and in what order. It's a markdown file with a one-line site description and grouped links. Perplexity, Claude, and several open crawlers already honor it; Google and OpenAI are expected to follow.
Every long-form page should carry a named author with a linked bio, credentials, and external presence (LinkedIn, GitHub, or a recognized publication). Add Person schema with sameAs entries — that's what AI engines use to score source reliability in 2026.
Position tracking still matters, but AI referral traffic now needs its own KPI. Tag inbound visits from chatgpt.com, perplexity.ai, gemini.google.com, and AI Overview parameters. Track how often your pages appear as citations — that's the real AEO scoreboard.
Answer engines now reward extractability over keyword density. Pages that open with a 40–60 word direct answer, use semantic HTML, and ship valid FAQPage or HowTo schema get lifted into AI Overviews and chat citations far more often than longer, less structured posts.
Prioritize Google AI Overviews and ChatGPT search — they drive the largest share of zero-click and assisted referral traffic in 2026. Perplexity and Gemini follow the same fundamentals, so a single well-structured page typically performs across all four.
Yes if you publish content you want LLM crawlers to use. A public /llms.txt at the site root lists the canonical URLs and a short description for each, which Perplexity, Claude, and several open crawlers already consume.
Schema and on-page structure changes are usually re-crawled within 1–3 weeks. Authority signals (author bios, external citations, brand mentions) compound over 2–3 months. Track citation rate, not just rankings.
