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

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

Search is changing. More people are asking ChatGPT and Perplexity for answers instead of Googling. When someone searches “best project management tool for remote teams,” they might get an answer from an AI engine that cites three companies. If your content isn’t optimized for AI search, you won’t be one of them.

This is where AEO (Answer Engine Optimization) comes in. It’s different from SEO, but you need both to stay visible as search evolves.

What Is SEO?

SEO (Search Engine Optimization) is optimizing your content to rank high in traditional search engines like Google and Bing.

When someone searches for “CRM for startups,” SEO helps your blog post or product page appear in the top 10 results. The goal is to get clicks to your website, where visitors can learn more and convert.

SEO focuses on:

Keyword research and targeting specific search terms
Creating content that matches what people are searching for
Building authority through mentions from other websites
Optimizing page speed, mobile-friendliness, and technical elements
Getting your pages indexed and ranked by search engines

SEO has been the foundation of content marketing for decades. If you want organic traffic, you need SEO.

What Is AEO?

AEO (Answer Engine Optimization) is optimizing your content so AI search engines like ChatGPT, Perplexity, Claude, and Google’s AI Mode can understand, cite, and recommend your content.

When someone asks ChatGPT “What’s the best way to reduce customer churn in SaaS?”, the AI pulls information from various sources to form its answer. If your content is well-structured and authoritative, you get cited. If not, your competitors do.

AEO focuses on:

Clear, structured content that AI can easily parse
Direct answers to specific questions
Authority signals that help AI trust your content
Natural language that works for conversational queries
Getting mentioned and cited by reputable sources

AEO is newer than SEO, but it’s becoming critical as more people use AI tools for research and decision-making.

AEO vs. SEO: Key Differences

While SEO and AEO both aim to increase visibility, they work differently because the platforms are different.

Feature	SEO	AEO
Primary Goal	Rank in search results to drive traffic to your website	Get cited as a source in AI-generated answers
Platform	Google, Bing, traditional search engines	ChatGPT, Perplexity, Claude, Google AI Mode
User Behavior	User clicks through to your site	User gets the answer directly, may or may not visit your site
Content Format	Optimized for keywords and search intent	Structured for AI parsing with clear answers
Success Metric	Rankings, organic traffic, conversions	Citations, brand mentions in AI responses
Key Tactics	Keyword research, on-page optimization, technical SEO, link building	Question-answer formatting, structured data, authority building, natural language

Is AEO Replacing SEO?

No. AEO is not replacing SEO. They work together.

Google is still the dominant search engine. People still search on Google and click through to websites. SEO remains essential for driving organic traffic.

But search behavior is changing. More people are using ChatGPT and Perplexity for quick answers, especially for research and comparison tasks. B2B buyers increasingly ask AI tools questions like “what’s the difference between Asana and Monday.com” instead of Googling.

The reality: People are using both. Google searches are increasing, and AI tool usage is also growing. Your prospects aren’t choosing between Google and ChatGPT. They’re using both at different stages of their research.

If you only optimize for SEO, you miss prospects who ask AI engines for recommendations. If you only optimize for AEO, you miss the traffic and conversions that come from traditional search.

The smart approach is optimizing for both.

How SEO and AEO Work Together

Good news: many SEO tactics also help with AEO. You don’t need to choose one or the other.

Tactics That Benefit Both SEO and AEO:

Creating high-quality, authoritative content: Both Google and AI engines favor content that demonstrates expertise and provides real value.

Building mentions from reputable sources: Links and citations from authoritative sites help with both traditional rankings and AI trust signals.

Using structured data (schema markup): This helps search engines and AI engines understand your content’s context and structure.

Writing clear, well-organized content: Good content structure helps both humans and AI understand what you’re saying.

Focusing on user intent: Whether someone searches on Google or asks ChatGPT, they want a helpful answer. Content that genuinely answers questions works for both.

The main difference is emphasis. SEO focuses on rankings and traffic. AEO focuses on being the answer AI gives.

When to Prioritize SEO

Focus on SEO when:

You’re targeting high-volume keywords where people want to explore multiple options
Your goal is driving traffic to your website for lead generation or conversions
You’re building long-term organic visibility and brand authority
You need consistent, measurable traffic month over month
Your prospects do extensive research before making decisions

SEO is still the foundation. If your website isn’t ranking on Google, you’re missing the majority of B2B buyers who start their research with traditional search.

When to Prioritize AEO

Focus on AEO when:

Your prospects are asking direct questions that AI can answer
You want to be the recommended solution when people ask AI tools for advice
You’re targeting question-based queries like “how do I reduce churn” or “what’s the best CRM for startups”
You want to future-proof your content strategy as AI search grows
Your competitors are getting cited by AI engines and you’re not

AEO matters more as AI adoption increases. B2B buyers are already asking ChatGPT and Perplexity for product recommendations. If your brand isn’t showing up in those responses, you’re invisible to a growing segment of your market.

How to Optimize for Both SEO and AEO

Here’s how to create content that works for traditional search engines and AI answer engines:

1. Start With Keyword Research (SEO) and Question Research (AEO)

For SEO, research the keywords your prospects are searching for. For AEO, research the questions they’re asking AI engines.

Example: Instead of just targeting “project management software” (SEO), also target “what project management software do remote teams use” (AEO).

2. Structure Content for Both Humans and AI

Use clear headings, direct answers, and logical flow. This helps Google understand your content and makes it easy for AI to parse and cite.

Start sections with the question, then provide a direct answer, then elaborate with details and examples.

3. Build Authority Through Mentions

Get featured in reputable publications, contribute expert quotes, and create content worth citing. Both Google and AI engines trust content that’s referenced by authoritative sources.

4. Use Structured Data

Schema markup helps both search engines and AI understand your content. Mark up FAQ sections, product information, and article structure.

5. Write in Natural Language

AI engines handle conversational queries better than keyword-stuffed content. Write like you’re answering a real person’s question, not gaming an algorithm.

6. Focus on Comprehensive, Original Content

Both SEO and AEO favor content that’s thorough, accurate, and adds something new. Generic content that repeats what’s already out there won’t rank on Google or get cited by AI.

Should You Hire a Writer Who Understands Both?

Most content writers only understand traditional SEO. They know how to target keywords and optimize for Google, but they don’t know how to structure content for AI engines.

Writing for both SEO and AEO requires understanding how AI engines parse content, what signals they use to determine authority, and how to create content that works for both platforms.

This is what I do for B2B SaaS companies. I create content strategies that target both traditional search rankings and AI citations. My content ranks on Google and gets cited by ChatGPT and Perplexity.

I’ve worked with companies like Supademo, StaffCircle, and SEOWriting.ai to build content that works for the current search landscape and prepares for the future of AI-powered search.

Final Thoughts

The debate about AEO vs. SEO misses the point. You need both.

SEO drives traffic from Google, which is still the dominant search engine. AEO gets you cited by AI engines, which are growing rapidly in adoption.

The good news is that many tactics work for both. Create high-quality, authoritative content. Structure it clearly. Build mentions from reputable sources. Answer real questions thoroughly.

Do this consistently, and you’ll rank on Google while also getting cited by ChatGPT, Perplexity, and other AI engines.

The companies that win in the next few years won’t be the ones choosing between SEO and AEO. They’ll be the ones doing both well.
