What Is AEO (Answer Engine Optimization)?
Answer Engine Optimization (AEO) is the practice of optimizing your brand's presence in AI-generated answers. When a buyer asks ChatGPT "what's the best project management tool for engineering teams?" or asks Perplexity "which cybersecurity vendors do mid-market companies actually trust?", AEO is the discipline that influences whether your brand appears in the response.
The mechanism is different from SEO. AI models don't rank pages. They synthesize information from their training data, real-time retrieval, and indexed sources. Getting cited by AI requires being present in the sources those models draw from, primarily peer communities like Reddit, review sites like G2, and authoritative third-party publications. A well-optimized brand page does not get you cited by Perplexity. A credible presence in the communities your buyers trust does.
AEO has become a serious channel priority because B2B buyer behavior is shifting. 73% of B2B buyers report using AI assistants in their purchase research. That's not a niche behavior. When those buyers get an AI-generated answer recommending three vendors, the brands not mentioned in the response are invisible. AEO is the discipline of ensuring you're not the brand that gets left out.
Reddit is the primary infrastructure layer for AEO. Reddit accounts for 40.1% of LLM citations across major AI models, and Reddit's representation in AI training data is structural. Nerativ uses Peec AI to track which AI models are citing Reddit content and how brand mentions in those citations are trending over time. That's the measurement layer for AEO that most agencies don't have access to.
What Is SEO (Search Engine Optimization)?
Search Engine Optimization is the practice of improving a website's ranking on search engines, primarily Google, for queries relevant to your business. The mechanism relies on technical site quality, content relevance, backlink authority, and keyword targeting. The success metric is organic search traffic and keyword rankings.
SEO has been the dominant B2B inbound channel for over fifteen years. Companies with strong SEO programs build durable traffic moats: pages that rank for high-intent queries keep producing leads without incremental media spend. The compounding nature of domain authority means early investment pays dividends for years.
The mechanism is well-understood. You identify queries your buyers are searching, produce content that matches the intent behind those queries, earn backlinks that signal authority, and optimize technical factors that affect crawlability and page speed. Google's algorithm ranks pages. Your job is to satisfy the algorithm's signals while genuinely serving the user.
SEO's reach is real, but it captures buyers who already know to search for something. When a buyer types "best endpoint detection response tool" into Google, they're in active search mode. SEO serves that moment well. It doesn't address the buyer who opens Claude and asks "what EDR platform would a senior security engineer actually recommend?" That query goes to an AI, not a search engine, and SEO doesn't determine the answer.
AEO vs SEO: Side-by-Side Comparison
| Factor | AEO | SEO |
|---|---|---|
| Target Outcome | Appear in AI-generated answers and citations | Rank on Google for relevant keyword queries |
| Algorithm | LLM training data, retrieval corpus, peer community citations | Google's ranking algorithm: backlinks, content, technical SEO |
| Success Metric | LLM citation rate, brand mentions in AI responses, AI-referred traffic | Keyword rankings, organic traffic, share of voice in SERPs |
| Timeline | Weeks to months; Reddit content indexes quickly in AI retrieval | 3-12 months for competitive keywords; faster for long-tail |
| Content Target | Peer communities, review sites, third-party publications | Owned domain: blog posts, landing pages, technical content |
| Role of Reddit | Primary. Reddit is the #1 LLM citation source | Supporting. Reddit posts appear in 37% of Google SERPs |
When AEO Should Be Your Priority
AEO takes priority when your buyers are asking AI assistants for recommendations before they ever run a Google search. This pattern is especially pronounced in technical and practitioner-heavy categories. A CISO researching endpoint protection, a developer evaluating API monitoring tools, a fintech founder comparing payment infrastructure providers — these buyers are increasingly starting their research with a conversational AI query, not a Google search.
Early-funnel category discovery is another AEO use case where SEO falls short. When a buyer asks "what are the best alternatives to [incumbent vendor]?" or "what does a good SIEM implementation look like for a 200-person company?", they're seeking synthesized guidance, not a list of links. AEO ensures your brand is part of that synthesized answer.
AEO also compounds differently than SEO. A Reddit thread that generates strong AI citations builds a signal that influences AI responses for months or years after the thread was posted. As AI models update their training data and retrieval corpora, well-cited Reddit content accumulates authority in those systems. That compounding effect is structurally similar to how backlinks work in SEO.
For brands that have already built strong SEO programs and are seeing diminishing returns from additional content investment, AEO represents the highest-impact frontier. The incremental buyer captured by AEO is different from the one captured by SEO, and the conversion rate is higher: AI-referred visitors convert at 4.4x the rate of organic search visitors.
When SEO Should Be Your Priority
SEO remains the right priority for capturing buyers who know what they're searching for and are using Google to find it. High-intent keyword searches like "best project management software for enterprises," "slack alternatives for large teams," or "how to implement zero trust security" represent buyers at a specific decision stage. SEO is optimized for exactly that moment.
For categories with high Google SERP volume, SEO offers scale that AEO doesn't match yet. The aggregate traffic from ranking for a cluster of related keywords can be substantial, and the cost per acquisition from well-ranked organic content is often lower than any paid channel over a multi-year horizon.
Comparison browsing is also better served by SEO. When a buyer types "[your brand] vs [competitor]" into Google, they're looking for a comparison page. That's an SEO play. A buyer asking ChatGPT the same question gets a synthesized answer, but buyers in comparison mode often still turn to Google for page-level detail. SEO serves the page-browsing behavior that SEO was built for.
Can You Optimize for Both Simultaneously?
Yes, and this is exactly what Nerativ's approach produces. Reddit content is uniquely positioned to serve both goals at the same time. A well-placed Reddit thread in an active subreddit targeting a specific buyer query can rank on Google's first page for long-tail terms, while simultaneously feeding the LLM citation corpus that influences AI-generated answers. Reddit posts appear in 37% of Google SERPs, making them a genuine dual-channel asset.
The content strategy for AEO and SEO also overlaps significantly. Both reward genuine expertise, specific answers to real questions, and trust signals from credible sources. A Reddit thread that authentically answers a practitioner question gets upvoted by the community (a community signal), indexed by Google (an SEO signal), and cited by AI models (an AEO signal). The same investment in genuine expertise serves three distribution channels at once.
Most B2B marketing programs that run both AEO and SEO find that they reinforce each other. SEO content on your owned domain establishes brand authority that AI models can draw on. Reddit-sourced AEO generates the peer citations that AI models weight most heavily. Together, they cover the buyer journey more completely than either does alone.

Frequently Asked Questions
SEO optimizes content to rank on search engines like Google, with keyword rankings and organic traffic as the primary metrics. AEO optimizes for being cited by AI models like ChatGPT, Perplexity, and Google AI Overview. They target different systems and different buyer behaviors, but the signals often overlap — especially through Reddit content, which both ranks on Google and gets cited by AI.
Both, run in parallel. SEO remains valuable for capturing keyword intent and driving traffic to owned content. AEO addresses the growing share of B2B buyers who ask AI assistants for vendor recommendations directly. 73% of B2B buyers report using AI in their purchase research, and AI-referred visitors convert at 4.4x the rate of organic search visitors. Ignoring either channel leaves buyers unaddressed.
Yes. Reddit is one of the few content channels that serves both goals simultaneously. Reddit posts appear in 37% of Google SERPs, making strategic Reddit threads an effective SEO lever for long-tail queries. Reddit also accounts for 40.1% of LLM citations across major AI models, making it the primary input for AEO. A well-placed Reddit thread can rank on Google and appear in Perplexity answers at the same time.
