SEO vs. AEO: What's the Difference and Do You Really Need Both?

3 min read

Side-by-side of a Google search results page and a ChatGPT answer card, showing the visual difference between SEO and AEO.

You've probably been hearing about AEO for a few months now. And if you've spent any time investing in SEO over the last few years, you're probably wondering: do I need to throw out what I was doing? Is SEO dead? Is AEO a replacement?

Short answer. No. They work together.

Long answer. That's what this post is for.

What SEO does

Search Engine Optimization gets your website ranked in traditional search results. The blue links. The ones that show up under the AI summary and the ads.

SEO works by signaling to Google (and Bing, and others) that your page is the most relevant, trustworthy answer to a specific search query.

The signals haven't changed dramatically in ten years.

  • Quality content.
  • Strong page structure.
  • Backlinks from credible sites.
  • Page speed.
  • A clear topical focus.

Do those things well and you rank.

What AEO does

Answer Engine Optimization gets your business cited by AI tools.

ChatGPT mentioning your name when a buyer asks for vendor recommendations. Perplexity pulling a quote from your blog post into its summary. Google AI Overviews summarizing your service page in response to a buyer question.

The signals look similar to SEO, but the emphasis is different.

AEO leans hard on Q&A structure, clear language that matches how real people ask things, schema markup that makes content parseable, and consistent publishing that signals "this business is still active and worth surfacing."

Where they overlap

A well-built AEO page usually ranks well in traditional Google search too. The reverse isn't always true. A page optimized only for keywords (the old SEO playbook) often misses the AEO signals entirely.

Here's the thing. If you're building new content, build it AEO-first. You get the SEO benefits as a bonus.

Where they don't overlap

SEO still cares about things AEO doesn't weigh as heavily.

  • Domain authority.
  • Backlink profile.
  • Site architecture.
  • Technical performance.

AEO cares about things SEO didn't traditionally rank by.

  • Q&A formatting.
  • Conversational language.
  • FAQ schema on every page.
  • Direct, citable answers in the first paragraph of a section.
  • ICP-aligned phrasing.

If you only do one, you'll have gaps. If you do both, the work compounds.

Do you need both?

Here's how I think about it with clients.

If your buyers research using Google and also use AI tools (true for almost every B2B buyer in 2026), yes. You need both.

If you sell something fast, transactional, and local (and your buyers find you through Google Maps and reviews), you can lean SEO-heavy with light AEO.

If you sell something high-consideration and your buyers research for weeks before they ever talk to you, you absolutely need both. They're using AI to compare options before they ever click your site.

What I actually recommend

Most of my clients run both. Not because it's trendy. Because the buyer journey now runs through both channels.

We build the foundational SEO during the website project (clean structure, fast pages, technical fundamentals, smart internal linking) and then layer AEO on top through ongoing content production on the retainer. The two reinforce each other.

Questions You Might Be Asking

No. SEO still drives most of the organic traffic for established businesses. AEO is layered on top of SEO, not a replacement for it. The work overlaps about 70% of the time, so doing it well means you get the benefit of both.

Probably not. Most sites need three things: clearer Q&A-style content on key pages, FAQ schema markup, and a consistent publishing cadence on the blog. None of that requires starting from scratch.

It depends on how your buyers research. If they Google your category and pick from the top results, lean SEO. If they ask ChatGPT or Perplexity for recommendations before they ever click a search result, lean AEO. Most growth-stage service businesses need both.

First citations typically show up in 90 to 120 days of consistent publishing. Steady visibility takes 6 to 12 months. SEO and AEO both compound, so the work you do this month keeps paying off a year from now.

Yes, if you build them right. A Q&A-structured post with FAQ schema, plain-English language, and clear answers will rank in Google and get cited by AI tools. That's the whole point of writing AEO-first.
