AEO vs GEO vs SEO: A Plain-English Guide for DMO Marketers

There is a good chance someone on your team has mentioned GEO recently. Or AEO. Or maybe both, possibly in the same sentence as "AI Overviews" and "generative search," with varying degrees of confidence about what any of it actually means.

The acronyms are multiplying faster than the industry can explain them, and most of the explanations out there are written for e-commerce brands or B2B software companies, not destination marketing organizations.

This guide breaks down all three disciplines in plain language, explains how they interact, and tells you where DMOs should focus first.

The Three-Layer Problem: Why One Strategy Is Not Enough Anymore

For most of the last two decades, destination marketing teams had one primary digital visibility goal: rank on Google. That meant keyword research, website optimization, content calendars pointed at Google rankings, and analytics dashboards full of organic traffic metrics.

That model worked because Google was where travelers started their research. It is still important, but it is no longer the whole picture.

According to NextTown's 2026 AI Search for Tourism Report, 46% of all trips Americans took last year involved AI search. The traveler journey now spans multiple discovery surfaces: Google's traditional results, Google's AI Overviews, ChatGPT, Perplexity, and others. A destination that only optimizes for one of these surfaces is invisible on the rest.

That is the three-layer problem. SEO, AEO, and GEO each address a different layer of how travelers now discover destinations.

SEO: Still the Foundation

Search Engine Optimization remains the base layer of digital visibility for DMOs. When a traveler types "things to do in Asheville" or "best fall foliage destinations" into Google, traditional SEO determines whether your website appears in the ranked results.

The fundamentals have not changed: your site needs to be technically sound, your content needs to match traveler intent, and your authority needs to be established through quality inbound links and consistent publishing.

What has changed is the role SEO plays relative to the other layers. SEO is now necessary but not sufficient. It is also worth noting that a strong SEO foundation supports your GEO and AEO efforts, because AI systems use many of the same signals traditional search does when evaluating content quality and authority.

For DMOs, SEO remains the right place to start if you have not done foundational work yet. But if your site is already well-optimized, the marginal return on further technical SEO investment is lower than it used to be. The bigger opportunity is in the two newer layers.

AEO: Getting Into Google's Answer Boxes and Featured Snippets

Answer Engine Optimization is the practice of structuring your content to be selected as a direct answer by AI-enhanced search systems. The most visible example is Google's AI Overviews, the AI-generated summary that now appears at the top of many travel search results, above the organic rankings.

When a traveler searches "best ski towns for families," they often see an AI Overview first. It names destinations, describes them briefly, and synthesizes information from multiple sources. Most travelers read this and never scroll further.

AEO is about getting your destination into that box.

The tactics differ from traditional SEO in a few important ways. AEO rewards content that is structured to be easily extracted. That means clear question-and-answer formatting, concise definitions, organized lists, and FAQ schema markup. It also rewards content that directly and confidently addresses specific queries rather than hedging or burying the answer.

A well-optimized AEO page for a DMO might have a clear H2 that reads "Is [Destination] good for families?" followed by a direct, confident, specific answer. Not a paragraph of marketing copy, but a clear response that an AI Overview can lift and use.

The good news for DMOs is that AEO-friendly content is also better content for human readers. Travelers want clear, specific answers. Writing for AEO generally means writing more helpfully.

GEO: Being Cited by ChatGPT, Perplexity, and Gemini

Generative Engine Optimization is the newest and, for many DMOs, the most important layer. It addresses the growing share of traveler discovery that happens not in Google at all, but in standalone AI platforms.

When a traveler asks ChatGPT "where should I go this summer with my family for an outdoor adventure?", no ranked list appears. The AI synthesizes a response and names destinations it considers most relevant. GEO is the discipline of ensuring your destination is one of them.

The mechanism is fundamentally different from SEO or AEO. As NextTown's 2026 AI Search for Tourism Report explains, AI platforms look first to user-generated content, primarily Reddit, TripAdvisor, and Quora, to form their opinions about where travelers should go. They look to your website last, and only for factual support once they have already decided to include your destination.

This means GEO requires off-site work that traditional SEO and AEO do not. You are not just optimizing your own content. You are building and shaping the broader ecosystem of content that AI reads to form its view of your destination.

The key takeaway from the table is that these are not competing strategies. They address different surfaces and require different, though overlapping, tactics. A piece of content written to answer a traveler question clearly (AEO) will also tend to rank well in traditional search (SEO) and build the topical authority that helps with GEO.

Where DMOs Should Focus First

The honest answer depends on where you are starting from.

If your destination website has significant technical issues, thin content, or almost no organic traffic, fix the SEO foundation first. Nothing else will work well without it.

If your website is in solid shape but you are not appearing in Google AI Overviews for your key topics, AEO is the highest-leverage next step. It is faster to see results and directly addresses the most common form of AI-generated search results your potential visitors encounter.

If your website is strong and you are appearing in some AI Overviews but you are not showing up at all when travelers ask ChatGPT or Perplexity where to go, GEO is where to focus. This is where the largest share of undiscovered opportunity lives for most DMOs right now, and where competition is still relatively low.

For most established DMO teams, the practical path is to run AEO and GEO work in parallel while maintaining existing SEO. They share enough infrastructure, good content, clear structure, topical authority, that pursuing them together is more efficient than sequential.

The destinations that are getting ahead of this are not treating these as three separate workstreams. They are building content strategies that serve all three surfaces simultaneously: clear enough for AI to extract and use, authoritative enough for Google to rank, and present enough across the web for generative AI to cite.
