A growing share of buyers no longer start at Google. They ask ChatGPT "what's the best tool for X," or let Perplexity hand them a shortlist. If your SaaS isn't in those answers, you're invisible to them, no matter how well you rank on traditional search. Getting into AI answers is its own discipline, and it has two names you'll see everywhere: AEO and GEO. Here's what they are and how to actually win them.
What's inside
Key takeaways
- AEO (answer engine optimization) is getting picked as the direct answer; GEO (generative engine optimization) is getting cited inside AI-generated answers like ChatGPT and Perplexity.
- AI engines synthesize from many sources, so what the wider web says about you matters as much as your own site. Third-party mentions are the biggest lever.
- Win it by being the clearest answer, earning mentions on Reddit and listicles, getting onto "best X" comparisons, and adding clean structure and schema.
- You still need SEO. The same authority and content that ranks on Google feeds the models that AI engines learn from.
- Measure it: track how often AI assistants mention your brand and where they pull citations from.
What are AEO and GEO?
Answer Engine Optimization (AEO) is the practice of optimizing your content to be served as the direct answer to a question, in places like Google's AI Overviews, featured snippets, and voice assistants. Generative Engine Optimization (GEO) is the practice of getting your brand mentioned and cited inside the answers that generative AI tools produce, like ChatGPT, Perplexity, Claude, and Gemini.
The two overlap heavily and people often use them interchangeably. The simplest way to hold them apart: AEO is about being the answer; GEO is about being in the answer. Both are about one thing that traditional SEO wasn't built for, getting chosen by a machine that's writing a response, not just ranking a list of blue links.
AEO vs SEO vs GEO: what's the difference?
Traditional SEO optimizes to rank a page in a list of search results, where the user then clicks through to your site. AEO and GEO optimize to be the answer itself, or a cited source within it, often with no click at all. The goals differ in a few important ways:
- The unit of success. SEO wins a ranking position. AEO/GEO win a mention or citation inside a synthesized answer.
- What's being optimized. SEO weighs heavily on your own pages and backlinks. GEO depends a lot on what the whole web says about you, because the model is summarizing many sources at once.
- Format. AI engines favor content that's clearly structured and directly answers questions, so they can lift a clean, quotable statement.
They're not rivals. AEO and GEO sit on top of good SEO, they don't replace it.
Why this matters for SaaS founders now
For SaaS specifically, this shift hits early in the buying journey. Founders, operators, and buyers increasingly open ChatGPT and ask "what's the best [category] tool for a [type of company]," and act on the three or four names it returns. If you're not one of them, you never even enter the consideration set, and you'll never see it happen in your analytics, because there was no click to track.
The opportunity: AI answers for most B2B SaaS categories are still being formed. The brands that show up consistently now are setting the defaults the models will keep repeating. Early movers compound.
How AI engines decide what to cite
No one has the exact recipe, but the patterns are clear from how these systems work. AI assistants tend to surface and cite sources that are:
- Clearly relevant and well-structured. Content that answers the question directly, near the top, in plain language the model can lift.
- Corroborated across the web. If many independent sites describe you the same way, the model is far more confident citing you. This is the single biggest factor and the one founders underrate.
- Authoritative. Established domains, real expertise, and recognizable brands get more trust, the same signals that help in SEO.
- Fresh. Recently updated content is more likely to be pulled for fast-moving topics.
- Machine-readable. Clean HTML, structured data, and crawlable pages make you easier to parse and quote.
How to get your SaaS to show up in ChatGPT
Here's the actual playbook, in priority order.
1. Be the clear answer on your own site
Write answer-first. Put a direct, quotable response in the first sentence under each heading, use real questions as headings, and add an FAQ with structured data. The page you're reading is built this way on purpose. Make it trivially easy for a model to extract a clean statement about what you do and who you're for.
2. Earn third-party mentions
This is the highest-leverage move and the one most founders skip. Because AI answers synthesize many sources, getting described consistently across the web matters more than any single page you own. Get genuinely useful mentions on Reddit and Hacker News, in industry roundups, on review sites like G2 and Capterra, and in other people's "best tools" articles. The more the web corroborates what you do, the more confidently AI will name you.
3. Win the "best X" and comparison queries
A huge portion of AI recommendations are pulled from listicles and comparison content ("best [category] tools," "[competitor] alternatives"). Get included in the ones that already rank, and publish your own honest comparisons. These pages are the raw material AI assistants quote when someone asks for a recommendation.
4. Add structure and clean technical signals
Use schema markup (Organization, Product, FAQ), keep your site fast and crawlable, and make your key facts unambiguous and consistent. Some teams also publish an llms.txt file, an emerging proposed standard that summarizes a site for AI crawlers. Adoption is still early, so treat it as cheap insurance, not a silver bullet.
5. Build your entity presence
Help the models know you exist as a real entity. Keep your brand description consistent across your site, LinkedIn, Crunchbase, G2, and anywhere else you appear, and earn a presence in the places models trust as references. Consistency across these sources is what lets an AI confidently connect the dots to your brand.
6. Measure and iterate
You can't improve what you can't see. Track how often AI assistants mention your brand for your target prompts, and which sources they cite, then double down on what's working. Tools like Ahrefs Brand Radar and dedicated AI-visibility trackers exist for exactly this.
Perplexity and Google AI Overviews
The same fundamentals apply across engines, with small differences in emphasis. Perplexity leans heavily on citations and tends to favor fresh, well-sourced pages, so clear content and third-party corroboration go a long way. Google's AI Overviews draw on Google's existing index, so strong traditional SEO and structured content carry over directly. ChatGPT blends its training with live web results, which is why broad, consistent web presence matters so much. Optimize for the principles, not one tool, and you'll show up across all of them.
Does traditional SEO still matter?
Yes, more than ever. AEO and GEO are built on the same foundation: authoritative, well-structured, widely-referenced content. The pages that rank on Google are often the same ones AI engines pull from, and Google's own AI Overviews run on its search index. Don't abandon SEO for AEO, layer AEO and GEO on top of a solid SEO base. Our SEO for SaaS guide covers that foundation.
How to measure your AI visibility
Start simple: write down the 10 to 20 prompts a buyer would actually type ("best [your category] for [your ICP]"), and check how often you're mentioned across ChatGPT, Perplexity, and Google AI Overviews. Then use a dedicated tracker to monitor mention frequency, share of voice versus competitors, and which sources get cited. That citation list is gold, it tells you exactly which third-party pages to go earn mentions on next.
Common AEO and GEO mistakes
- Only optimizing your own site. The web's consensus about you matters more than any single page. Earn the mentions.
- Burying the answer. If a model has to dig, it won't quote you. Lead with the clear statement.
- Ignoring comparison and review content. That's where most AI recommendations come from.
- Treating it as a one-off. AI answers shift constantly; this is an ongoing motion, not a project.
- Dropping SEO. You'd be kicking out the foundation AEO and GEO stand on.
When to bring in help
AEO and GEO are new enough that most SaaS founders are figuring it out from scratch, while also trying to build the product and run the rest of go-to-market. The work, structuring content, earning third-party mentions, getting onto comparison lists, and tracking AI visibility, is exactly the kind of thing a fractional go-to-market partner runs for you.
This is part of what we do at SaaS Stars, a fractional VP of Sales & Marketing for B2B SaaS. We run inbound, AEO, and GEO so your startup shows up where buyers are actually looking, including inside ChatGPT and Perplexity.
AEO & GEO FAQ
What is answer engine optimization (AEO)?
Answer engine optimization is the practice of optimizing content to be served as the direct answer to a question, in places like Google AI Overviews, featured snippets, and voice assistants. It focuses on clear, structured, directly-answering content that a machine can lift and present as the answer.
What is generative engine optimization (GEO)?
Generative engine optimization is the practice of getting your brand mentioned and cited inside the answers generative AI tools produce, such as ChatGPT, Perplexity, Claude, and Gemini. Because these tools synthesize many sources, GEO depends heavily on what the wider web says about you, not just your own pages.
AEO vs SEO: what's the difference?
SEO optimizes to rank a page in a list of search results that users click through to. AEO optimizes to be the answer itself, served directly by a search or answer engine, often with no click. They share the same foundation of authoritative, well-structured content, but AEO targets the answer box rather than the ranking.
How do I get my SaaS to show up in ChatGPT?
Make your site the clear, structured answer for your category, earn consistent mentions across third-party sites like Reddit, review platforms, and "best tools" listicles, get included in comparison content, add schema and clean technical signals, and keep your brand description consistent everywhere. AI assistants name brands the web corroborates, so broad, consistent presence is what gets you cited.
How do I rank on Perplexity?
Perplexity leans heavily on citations and favors fresh, well-sourced content. Publish clear, directly-answering pages, earn references from credible third-party sources, and keep content current. The same content and authority signals that help in ChatGPT and Google AI Overviews help in Perplexity too.
Does SEO still matter for AI search?
Yes. AEO and GEO are built on the same foundation as SEO: authoritative, well-structured, widely-referenced content. Google AI Overviews run on Google's search index, and the pages that rank well are often the same ones AI engines cite. Layer AEO and GEO on top of solid SEO rather than replacing it.
