For twenty years, “search marketing” meant one thing: rank on Google. That’s no longer the whole picture. A growing share of buying research now happens inside AI assistants and AI-generated search summaries — and most businesses have no strategy for showing up there at all.

What Is AEO (Answer Engine Optimization)?

AEO is the practice of structuring your content so that AI assistants — tools like ChatGPT, Perplexity, and voice assistants — can understand it well enough to surface your business as a direct answer to a customer’s question. Instead of optimizing purely for a ranked list of blue links, you’re optimizing for a single, well-sourced answer.

In practice, that means clear, factual content, well-structured headings, straightforward answers to common questions near the top of a page, and information that’s easy for an AI system to extract and attribute correctly — not buried in vague marketing language.

What Is GEO (Generative Engine Optimization)?

GEO is closely related but focused on a different surface: the AI-generated summaries and overviews that now appear directly inside search engines. When someone searches a question and gets a generated summary before they ever see a traditional result, GEO is about making sure your brand is the one being cited, accurately, inside that summary.

Why This Matters for Cost Per Acquisition

Traditional SEO and AEO/GEO aren’t competing strategies — they compound. Content built to rank well also tends to be well-structured enough for AI systems to cite. But businesses that ignore this shift are starting to lose visibility in a channel that costs nothing per click, while their competitors quietly absorb that free traffic. Over time, that shows up as a higher blended cost per acquisition — not because ads got more expensive, but because a free channel got smaller.

Where to Start

  • Audit your existing content for clear, direct answers to the actual questions your customers ask.
  • Make sure factual details about your business (services, pricing structure, service area, policies) are stated plainly and consistently across your site.
  • Use clean heading structure so both search engines and AI systems can parse your content correctly.

AEO and GEO are still early — which means the businesses that get organized now have a real head start. If you want a plain-language audit of where your content stands, get in touch and we’ll take a look.
