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

SEO gets you ranked on Google. AEO gets you cited by ChatGPT, Perplexity, and other AI search engines. Here’s the difference between AEO and SEO, and why your B2B SaaS brand needs 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

The biggest practical difference is what happens after someone finds you. With SEO, a user clicks your link, lands on your site, and you control the experience from there. With AEO, the AI pulls from your content and presents it directly in the chat. The user may never visit your site, but your brand still shows up at the exact moment they’re making a decision.

That’s why AEO matters for B2B SaaS. A lot of buying decisions now start inside AI tools, not on a Google results page.

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 organic traffic.

But search behavior is shifting. 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. These comparison-style queries are exactly the type of content AI engines love to cite, because they can pull structured answers and present them side by side.

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. If you want to dig into the SEO side specifically, here’s a full breakdown of what it takes to make SaaS content rank on Google.

Building mentions from reputable sources. Links and citations from authoritative sites help with both traditional rankings and AI trust signals. When Perplexity or ChatGPT decides which sources to cite, they weight content that other credible sites already reference.

Using structured data (schema markup). This helps search engines and AI engines understand your content’s context and structure. FAQ schema, article schema, and product schema all make it easier for AI to parse your pages accurately.

Writing clear, well-organized content. Good content structure helps both humans and AI understand what you’re saying. If a section starts with a clear question and follows with a direct answer, both Google and AI engines can extract that information quickly.

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. If that’s where you’re stuck, this post breaks down the most common reasons SaaS content fails to rank and what to do about it.

For most B2B SaaS companies, SEO should come first. Build a base of content that ranks and brings in traffic. Then layer AEO on top of that foundation.

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. The shift is backed by data. Recent AI SEO statistics show just how fast AI search tools are growing in B2B research workflows. 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.

You should also pay attention to what your prospects are actually doing. Open ChatGPT or Perplexity and search for queries related to your product category. See who gets cited. If it’s your competitors and not you, that’s a clear signal.

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).

The overlap is bigger than you’d expect. Most high-value keywords have natural question variants that AI engines pick up. Start with your core keyword list, then turn each term into the 2-3 questions a buyer would actually ask.

Don’t overlook terms with little or no reported search volume either. In SaaS, zero-search-volume keywords often carry high intent and face less competition from both Google and AI results. These long-tail, conversational queries are exactly what people type into ChatGPT.

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. If you need a practical checklist, this guide to on-page SEO for SaaS blog posts covers the structural elements that matter most.

Start sections with the question, then provide a direct answer in the first 1-2 sentences, then elaborate with details and examples. This “answer first, context second” approach is what AI engines are looking for when they scan content.

For example, if your H2 is “What’s the best CRM for startups?”, don’t spend three paragraphs building up to the answer. Lead with it. Then explain why. AI engines pull from the first clear answer they find under a relevant heading.

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.

For SaaS companies, this means getting mentioned in industry roundups, contributing to niche publications, and building a presence in communities where your audience spends time. The more places your brand appears as a credible source, the more likely AI engines are to cite you.

Guest posts on high-authority blogs still help SEO. But they also feed the training data and citation pools that AI engines pull from. So link building and AEO authority building are more connected than people realize.

4. Use Structured Data

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

For blog posts, article schema and FAQ schema are the highest-impact additions. For product pages, product schema with pricing, ratings, and feature details gives AI engines structured data they can reference directly.

If you’re not using any schema yet, start with FAQ schema on your most question-heavy posts. It’s low effort and high return for both SEO (featured snippets) and AEO (AI citations).

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 trying to hit a keyword density target.

This is a mindset shift for a lot of SaaS content teams. Traditional SEO trained writers to think in terms of exact-match keywords. AEO rewards content that sounds like something a knowledgeable person would actually say. For a deeper look at how to get this balance right, here’s a guide on how to write SaaS content that reads well for both humans and search engines.

Read your content out loud. If it sounds stiff or unnatural, AI engines will treat it the same way a human would: skip it and look for a better source.

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.

Most of the time, the problem isn’t effort. It’s avoidable mistakes in strategy and execution. Here’s a rundown of the most common SaaS content marketing mistakes teams make, and they apply equally to SEO and AEO.

The best content for both platforms includes original examples, specific data, and insights that can’t be found in every other article on the topic. If you’re writing a post about CRM tools for startups, don’t just list features. Include specific scenarios, pricing context, and the trade-offs a startup founder actually cares about.

AI engines are especially good at detecting when content is just a rewrite of existing top results. They’ve already seen that information. What gets cited is the article that adds a new angle, a better framework, or a more specific answer.

Should You Hire a Writer Who Understands Both?

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

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. It also requires staying current. The way ChatGPT, Perplexity, and Google AI Mode handle citations is changing fast.

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

I’ve worked with companies like Supademo (G2’s #5 Fastest Growing Software), SEOWriting.ai, and leading content marketing agencies like Graphite to create content that works for the current search landscape and prepares for what’s coming next.

Final Thoughts

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

SEO gets you 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.

Common Questions About AEO and SEO

What is the difference between AEO and SEO?

SEO optimizes content to rank in traditional search engines like Google, where the goal is getting clicks to your website. AEO optimizes content to get cited by AI search engines like ChatGPT and Perplexity, where the goal is being the source AI references in its answers.

Is AEO replacing SEO?

No. Google is still the dominant search engine, and SEO remains essential for organic traffic. AEO is an additional layer that helps your content get cited by AI tools, which are growing in adoption but not replacing traditional search.

Do I need both AEO and SEO for my SaaS company?

Yes. Your prospects use both Google and AI tools at different stages of their research. Optimizing for only one means you’re invisible on the other, and most B2B buyers now switch between traditional search and AI engines depending on the type of question they have.

How do I optimize content for AI search engines?

Structure your content with clear headings, direct answers to specific questions, and schema markup so AI engines can easily parse and cite it. Build authority through mentions from reputable sources, since AI engines weight content that other credible sites already reference.

How do I know if my content is being cited by AI engines?

Search for questions related to your product category in ChatGPT, Perplexity, and Google AI Mode, then check if your brand or content gets mentioned. Unlike SEO, there’s no single dashboard for AEO citations yet, so manual spot-checking and monitoring brand mentions are the primary methods.
