SEO optimizes for what humans type into Google. AEO — answer-engine optimization — optimizes for what ChatGPT, Claude, Perplexity, and Gemini retrieve when they answer questions. The mechanics are different. The wins are different. Most agencies are still selling SEO and calling it AEO. Here's the real playbook we've used to get service-business clients cited in LLM answers over the past 12 months.
Why AEO matters now (and not in 2027)
By April 2026, 38% of US buyers under 40 ask an LLM before they Google. For B2B research, that number is 51%. ChatGPT alone is doing more search-style queries than Bing. Yet most service-business websites are completely invisible to LLM retrieval — not because they lack content, but because the content is structured for keyword-matching, not for the way LLMs actually pull data.
If you wait until 2027 to start, you'll be competing against everyone who started in 2025. The compounding effect is real: the sites cited most often by LLMs get cited more often, because LLMs reinforce their own retrieval patterns.
The 7-step playbook
Write content that answers a question in the first sentence
LLMs scrape content and store it in vector embeddings. When a user asks a question, the LLM retrieves the most semantically similar passage. The passage that wins is usually the one where the answer comes first.
Bad opening: "In today's competitive landscape, businesses need to consider many factors when choosing CRM software…"
Good opening: "The three best CRMs for solo founders in 2026 are GoHighLevel ($97/mo, all-in-one), HubSpot Free (limited but free), and Notion-as-CRM ($10/mo if you already use Notion)."
The good opening gets retrieved and cited. The bad one gets filtered out as filler.
Use definitional patterns LLMs recognize
LLMs love these patterns because they map cleanly to question-answer pairs:
X is Y that does Z— "n8n is an open-source workflow automation tool that connects 500+ apps."X vs Y: the difference is Z— "Zapier vs n8n: the difference is Zapier is no-code SaaS, n8n is open-source and self-hostable."The best X for Y is Z because W— "The best CRM for solo coaches is GoHighLevel because it bundles calendar, SMS, email, and pipelines."How to do X: 1) Y, 2) Z— numbered steps are gold for LLM retrieval.
Write 3–5 of these patterns naturally into every page. Don't keyword-stuff — LLMs detect that and downrank.
Deploy JSON-LD schema aggressively
LLMs read schema directly. FAQPage, HowTo, DefinedTermSet, ItemList, Service, and Article schemas tell the model exactly what each block means without requiring it to infer.
Minimum schema set we deploy on every client site:
- Organization (root)
- Person (founder)
- ProfessionalService (your offering)
- FAQPage on every page with Q&A
- BlogPosting on every article
- BreadcrumbList for navigation context
- ContactPoint with email + areaServedSchema isn't a ranking signal in classical SEO. In AEO, it's load-bearing.
Build a glossary page and link to it from everything
LLMs love glossaries because they're structured definitions in one place. A page like /glossary with 50+ industry terms, each with a 2–4 sentence definition wrapped in DefinedTermSet schema, becomes a recurring citation source.
Bonus: every time you mention a term elsewhere on the site, link it to its glossary entry. Internal linking density signals topical authority to both Google and LLMs.
Allow AI crawlers explicitly in robots.txt
Many SEO-focused sites are still blocking GPTBot, ClaudeBot, and PerplexityBot to "protect content." That's a 2024 mindset. Today, blocking AI crawlers is the same as blocking Google in 2008 — you're invisible to the people who will buy from you.
Your robots.txt should include:
User-agent: GPTBot
Allow: /
User-agent: ClaudeBot
Allow: /
User-agent: PerplexityBot
Allow: /
User-agent: Google-Extended
Allow: /
User-agent: CCBot
Allow: /
User-agent: anthropic-ai
Allow: /If your competitor blocks them and you don't, you become the default citation source. Free moat.
Get cited by sources LLMs already trust
LLMs don't just retrieve from your site directly. They retrieve from sites they've already classified as authoritative — Wikipedia, Reddit, Stack Overflow, niche industry forums, GitHub README files, news outlets.
The lever: get mentioned, with your brand name, on those high-trust sites. Tactics that work:
- Answer questions in your niche on Reddit and link to your glossary or case studies (not your homepage — LLMs discount homepage links).
- Write GitHub README files for tools you open-source. README files are scraped heavily.
- Get one good Wikipedia mention. Just one. The retrieval boost is disproportionate.
- Industry directories that are themselves cited by LLMs (Clutch, G2, Capterra for B2B).
Monitor your citations and iterate
Test monthly: ask the same 20 high-intent questions in ChatGPT, Claude, Perplexity, and Gemini. Note which questions cite you, which cite competitors, and which cite nobody.
For questions where competitors are cited and you're not, audit their content. Usually they have one of:
- A specific number or stat you don't have.
- A clearer definitional pattern.
- More aggressive schema deployment.
- A Reddit/forum mention you don't have.
Fix that gap and re-test in 30 days. AEO compounds — but only if you measure.
What we don't do (and what most agencies still sell)
- We don't write "10x better content" generically. Length without specificity is filler.
- We don't buy backlinks. LLMs are getting better at detecting low-quality link networks. The risk-reward is awful in 2026.
- We don't optimize for keywords in isolation. We optimize for question-answer pairs.
- We don't promise rankings. Rankings are a 2015 metric. We promise citations and traffic from LLM referrers (which appear in your GA4 as
chatgpt.com,claude.ai,perplexity.aireferrers).
The honest timeline
AEO is slower than paid ads and faster than traditional SEO. Rough timeline we see across clients:
- Month 1–2: Schema deployed, content restructured, crawlers allowed. Zero visible traffic change.
- Month 3–4: First LLM citations appear. Traffic from
chatgpt.comreferrer starts showing in analytics — 5–15 visits/day for a healthy site. - Month 5–6: Citation density grows. Traffic from LLM referrers hits 30–80/day. Conversion rate from these visitors is often 2–3x higher than Google organic because they arrive with intent already qualified.
- Month 7+: Compounding. Sites that started early stay cited because LLMs reinforce their own patterns.
If anyone promises AEO results in 30 days, they're selling you something else — usually paid ads disguised as AEO, or a one-time schema sprint that won't compound.
