SEO Is Not Dead. But It Is No Longer Enough.
Your customers are asking ChatGPT, Claude, and Perplexity for recommendations. If AI cannot read your site, you do not exist in that conversation.
For 20 years, the game was simple. Rank on Google, get traffic, win.
That game still exists, but a second game started while most businesses were not looking. People now ask AI assistants for answers, recommendations, and comparisons. ChatGPT, Claude, Perplexity, and Google's own AI overviews are answering questions that used to end in ten blue links.
This is Answer Engine Optimization, or AEO. And most websites are invisible to it.
Here is the uncomfortable truth. Your site can rank number one on Google and still never be mentioned by an AI assistant. The two systems read the web differently.
What answer engines actually look for:
Clear, direct answers. AI models favor content that answers a question in the first two sentences, then elaborates. Burying your answer under 800 words of preamble worked for dwell time. It fails for AI extraction.
Structured content. Headings that match real questions. FAQ sections. Schema markup. Clean HTML. AI parsers reward structure the way librarians reward labeled shelves.
An llms.txt file. Just as robots.txt told search crawlers what to do, llms.txt tells AI models what your site is about and where your key content lives. Almost nobody has one yet. That is the opportunity.
Consistency and authority. AI models cross-reference. If your site, your social profiles, and third-party mentions all tell the same story, you become a safe answer to cite. If they contradict each other, you get skipped.
Real usefulness. This one never changes. Thin content written for algorithms fails in both games. Content that genuinely helps a specific person with a specific problem wins in both.
The practical move is not to abandon SEO. It is to make your existing content readable by both humans and machines. Most sites need structural fixes, not rewrites.
I built AEO Bob to do exactly this. It audits your site the way an AI model reads it, scores you, and gives you specific fixes, including generating your llms.txt file. It started as a WordPress plugin and is growing into a platform-agnostic engine.
Run the audit before your competitors do. The early movers in AEO will own the AI answer space the way early SEO adopters owned Google.
FAQ: Common Questions
Q: Is SEO dead?
A: No. Traditional SEO still drives traffic, but it is no longer enough on its own. AI answer engines like ChatGPT, Perplexity and Google AI Overviews summarise answers instead of sending clicks, so you also need to be citable, not just rankable.
Q: What is Answer Engine Optimization (AEO)?
A: AEO is structuring your content so AI-powered answer engines can find, understand and cite it — clear question-and-answer formatting, structured data such as FAQPage and Article schema, and factual, self-contained statements.
Q: How do I make my site AI-citable?
A: Add FAQ and Article structured data, answer questions directly in the first sentence, keep facts unambiguous, publish an llms.txt file, and make sure content is crawlable without JavaScript. AEO Bob at aeobob.com audits all of this automatically.
