For the past decade, every real estate agency website conversation has started the same way: "How do we rank higher on Google?". That question is still valid. But there's a new question that matters just as much now: "How do we get recommended by ChatGPT?"
These are fundamentally different challenges — and they require different approaches. Understanding both, and the significant overlap between them, is what separates the agencies that will dominate property search in the next five years from those that won't.
The Core Difference
SEO (Search Engine Optimisation) is about making your website rank in the blue-link results when someone types a query into Google. The model is: user searches → Google returns a list of ranked pages → user clicks a link and visits your site.
AEO (Answer Engine Optimisation) — also called GEO, Generative Engine Optimisation — is about getting your agency cited, recommended, or referenced directly by an AI model like ChatGPT, Perplexity, Claude, or Gemini. The model is: user asks a question → AI gives a direct answer with sources → user contacts the cited agency directly, without ever visiting a list of search results.
The buyer journey is fundamentally different. In the SEO model, your site needs to earn a click. In the AEO model, the AI is already making the recommendation for you — or against you.
Key insight: When a buyer asks ChatGPT "which new-build agencies operate on the Costa Blanca?", they're not going to click through 10 results. They'll take the AI's answer and contact the agencies named. Being named — or not — is binary.
Side-by-Side Comparison
| Factor | SEO | AEO |
|---|---|---|
| Goal | Rank in Google search results | Get cited by AI models |
| Primary signal | Backlinks, authority, keyword relevance | Structured data, entity clarity, Q&A content |
| Content style | Long-form, keyword-optimised articles | Direct Q&A, factual statements, structured markup |
| Technical requirement | Page speed, crawlability, meta tags | JSON-LD schema, semantic HTML, XML feed enrichment |
| Time to results | 3–12 months (competitive markets) | 4–8 weeks (initial citations) |
| Competition level | Very high in most markets | Low — most agencies haven't started |
| Traffic model | Clicks to your website | Direct recommendations, zero-click |
| Ongoing effort | Continuous content + link building | One-time setup + periodic content |
What Overlaps (And Why That's Good News)
Good SEO and good AEO share the same foundation. The agencies that will win at both are the ones that focus on this core:
High-quality, factual content
Google's helpful content guidelines and AI model citation preferences both reward the same thing: content that genuinely answers questions, from an authoritative source, without fluff. An article that clearly answers "What is the purchase process for foreigners buying property in Spain?" will rank on Google AND get cited by Perplexity. Same investment, double benefit.
Structured data
Schema markup — the JSON-LD code that defines your agency as a machine-readable entity — improves Google rich results AND AI citation probability. Adding Organization, Service, FAQ, and RealEstateListing schemas is one of the highest-leverage technical investments any agency website can make.
Location and specialisation specificity
Both Google and AI models reward specificity. "Real estate agency" is too vague to rank or cite. "New-build property specialist on the Costa Blanca, operating in Javea, Denia, and Moraira" is specific enough to match precise queries — on both traditional and AI search.
Where They Diverge: What AEO Needs That SEO Doesn't
While the foundations overlap, AEO has specific requirements that traditional SEO rarely addresses:
Entity definition
AI models work with entities — named things with known attributes. Your agency needs to be a clearly-defined, consistently-named entity across your website, your Google Business Profile, your social profiles, and any press mentions. Inconsistent naming ("Opero", "Opero Agency", "Opero Real Estate Marketing") confuses AI models and reduces citation confidence.
Conversational Q&A content
Traditional SEO often uses long-form blog posts structured around keywords. AEO needs content structured around direct questions and direct answers — the kind of content an AI can extract a clear, citable answer from. "Q: What areas does your agency cover? A: We specialise in new-build property across the Costa Blanca, including Javea, Denia, Moraira, and Altea." That's AEO-ready. "We serve a wide range of locations across beautiful Costa Blanca" is not.
XML feed enrichment
This is specific to real estate. Your property listings are your product inventory — and for AI models to cite them, they need to be rich, structured, and readable. Enriching your CRM's XML export with AI-generated natural-language descriptions, semantic attributes, and schema markup is a purely AEO task with no real SEO equivalent. It's also where some of the biggest citation gains come from.
How to Prioritise Both
If your agency is starting from scratch on both SEO and AEO, here's how to think about it:
- Do the structural work first (benefits both). Schema markup, clear entity definition, fast and crawlable website. This is a one-time investment that improves your baseline for everything else.
- Build Q&A content (benefits both, but especially AEO). Write 10-20 pieces of content that directly answer the questions your buyers ask. These will rank on Google over time and get cited by AI immediately.
- Enrich your property feeds (AEO-specific). Get your listings AI-readable. This is the highest-leverage AEO investment specific to real estate.
- Build authority over time (SEO-specific). Backlinks, domain authority, and content volume are still SEO levers — but they take time. Focus here after the structural work is done.
The opportunity right now: In most real estate markets, AEO competition is near zero. The agencies that invest in AI search visibility in 2026 will build a citation advantage that compounds over time — just as early SEO movers in 2010-2015 built domain authority that's nearly impossible to compete with today. The window is open. It won't stay open.
The Bottom Line
SEO and AEO are not competing priorities — they're complementary. The same clear, structured, authoritative content that ranks on Google also gets cited by ChatGPT. The structural investment in schema markup and entity clarity improves both simultaneously.
The difference is urgency. In most real estate markets, SEO is already a crowded, expensive, long-term game. AEO is still wide open. For most agencies, investing seriously in AEO right now — while competitors are still focused exclusively on Google — is the highest-leverage marketing decision available.
The buyer who starts their property search on ChatGPT is typically a higher-intent, more decisive buyer. They've already decided they want to buy. They're asking AI to shortlist agencies. Getting named in that answer is worth more than ranking third on Google for a competitive keyword.
