AEO vs SEO: What's the Difference and Why You Need Both
Search Engine Optimization got your business on Google. AI Engine Optimization gets your business recommended by ChatGPT. Here is how they compare — and why the smartest businesses are investing in both.

The Core Difference
SEO (Search Engine Optimization) optimizes your website to rank higher in traditional search engine results — the ten blue links on Google. AEO (AI Engine Optimization) optimizes your website to be cited and recommended in AI-generated answers — the responses from ChatGPT, Perplexity, Google AI Overviews, and similar tools.
Both are about discoverability, but they target fundamentally different interfaces. SEO targets a list of links. AEO targets a synthesized answer.
Side-by-Side Comparison
| Factor | SEO | AEO |
|---|---|---|
| Optimizes for | Google, Bing rankings | ChatGPT, Perplexity, AI Overviews citations |
| Success metric | Rankings, clicks, traffic | Citations, mentions, recommendations |
| Content focus | Keywords, backlinks, page authority | Structured answers, entities, schema |
| User experience | User clicks a link and visits your site | AI cites you in a direct answer |
| Schema importance | Helpful but optional | Critical and essential |
| Content structure | Important for readability | Essential for machine parsing |
| Question-based headings | Nice to have | Strongly recommended |
| Entity clarity | Moderate impact | High impact — AI needs to know who you are |
| Freshness signals | Affects some queries | Affects all citations |
| Audience | Everyone who uses Google | Growing: Gen Z, professionals, early adopters |
| Competition | Extremely competitive | Low competition — early mover advantage |
What SEO Does Well (That AEO Doesn't Replace)
SEO remains essential for several reasons that AEO does not address:
- Direct website traffic. SEO drives visitors to your actual website where they can browse, buy, and convert. AI citations may reference you without the user ever visiting your site.
- Established measurement. SEO has mature tools for tracking rankings, traffic, and conversions. AEO measurement is still emerging.
- Broader reach. Not everyone uses AI assistants yet. Traditional search still handles the majority of queries globally.
- Local pack results. Google's map pack and local results are still SEO-driven and remain a critical traffic source for local businesses.
What AEO Does (That SEO Misses)
AEO addresses critical gaps that traditional SEO does not:
- AI-generated recommendations. When someone asks ChatGPT "what is the best AEO tool?" your SEO ranking is irrelevant — what matters is whether your site is structured for AI citation.
- Zero-click visibility. Many AI interactions never result in a click. Being cited in the answer itself is the new form of visibility — and AEO is how you get there.
- Entity disambiguation. AI needs to know exactly who you are and what makes you different from competitors with similar names. AEO focuses on entity clarity in ways SEO does not.
- Machine-readable structure. While SEO considers headings and structure, AEO takes it further by optimizing for how AI models specifically parse and extract information.
The Overlap: Where SEO and AEO Reinforce Each Other
The good news is that many optimizations benefit both SEO and AEO:
- Schema markup improves both Google rich results and AI citations
- Clean heading structure helps both search crawlers and AI parsers
- Fast page speed improves both search rankings and AI crawl success
- High-quality content ranks better in search and gets cited more by AI
- Mobile responsiveness is a factor in both SEO rankings and AI crawling
- HTTPS and technical health are baseline requirements for both
- XML sitemaps help both Google and AI discover your content
This overlap means that investing in AEO often improves your SEO at the same time. It is not an either/or decision — it is a both/and strategy.
How to Build a Combined SEO + AEO Strategy
- Audit both. Run a free AEO scan alongside your existing SEO tools to see where you stand on both fronts.
- Fix shared foundations first. Technical health, page speed, sitemaps, meta tags, and heading structure benefit both strategies.
- Add schema markup. This is the biggest AEO-specific improvement that also helps SEO rich results.
- Restructure content for AI. Add question-based headings, clear definitions, and direct answers without removing the keyword optimization that supports SEO.
- Monitor both channels. Track your search rankings AND your AI citations. The businesses that measure both will adapt fastest.
The Bottom Line
SEO and AEO are not competitors — they are partners. SEO gets you found on Google. AEO gets you recommended by AI. The businesses that thrive in 2026 and beyond will be the ones that optimize for both discovery channels simultaneously.
The first-mover advantage in AEO is real. While your competitors are still focused exclusively on SEO, you can be building the AI visibility that will matter more every year. Start with a free AEO scan to see where you stand.
Frequently Asked Questions
Can I do AEO without SEO?
Technically yes, but it is not recommended. Good SEO creates the technical and content foundation that AEO builds on. Think of SEO as the floor and AEO as the ceiling — you need both for maximum visibility.
Will AEO replace SEO?
No. SEO and AEO will coexist. Traditional search is not going away — but AI-powered search is growing rapidly alongside it. The winning strategy is optimizing for both channels simultaneously, which is increasingly possible since many optimizations benefit both.
Which should I invest in first, AEO or SEO?
If you already have good SEO, prioritize AEO improvements — you likely have an untapped opportunity. If your SEO basics are weak (no sitemap, no meta tags, poor structure), fix those first since they also support AEO. Use the free Vida AEO scan to see where you stand.
Does improving AEO hurt my SEO rankings?
No — the opposite. Nearly every AEO optimization (better schema, cleaner structure, faster loading, clearer content) also improves traditional SEO. The two strategies are complementary, not competitive.
