1. What Is AEO — And How Is It Different From SEO?
Organic Google search traffic is down 33% globally and 38% in the U.S. from November 2024 to November 2025, according to a Chartbeat analysis reported by Search Engine Land. The traffic did not disappear. It got intercepted. AI is answering more questions before users ever reach a website — and PR professionals need a framework for what comes next.
AEO is not SEO 2.0. There is crossover, but there are new rules, new strategies, and new early winners. The clearest way to distinguish them:
- SEO — Getting found by search engines like Google through structured data and content rankings.
- AEO (Answer Engine Optimization) — Getting chosen by AI tools like ChatGPT, Perplexity, and Google’s Gemini.
- GEO (Generative Engine Optimization) — Shaping how AI represents your brand in a general conversational context. When a user is actively conversing with an LLM, how is your brand being described?
SEO and AEO together form the narrative that GEO delivers. Think of it as a house: SEO is the foundation, AEO is the frame, and GEO is the roof.
The good news: if your site is already technically sound, being crawled by Google, and surfacing in search — it is eligible to be surfaced by AI systems too. This is not starting from scratch. Or a rebuild. It’s an enhancement. Each layer builds on the one below it.
2. What Has Changed: Prompt Research Over Keyword Research
Keyword research is not going away. It is still part of SEO, and SEO is not being replaced. But now you need to layer in prompt research on top of it.
“Best PR firms New Mexico” is a keyword-dense phrase users have been trained to search since the early 2000s. But voice search and longtail keyword strategies have been changing behavior for years, and AI has accelerated them further. People are now conversational. They ask: What’s the best way to handle a brand crisis in 2026?
Your content needs to answer questions the way people actually ask them — naturally, conversationally, in plain language. The shift is from what to rank for to what to answer.
3. How AI Decides What to Surface: The BRAIN Framework
The following framework comes from The AEO Blueprint, published in October 2025. It’s important to note that it is not an industry standard, as E-E-A-T is with Google. Rather, it is a methodology and theory for how to tackle AI search in its early days. The book itself acknowledges that the information may already be evolving by the time you read it. That said, the core principles are sound and likely to remain relevant even as the terminology may shift.
The framework covers Brand Representation, Authority, and Indexability:
- Are you showing up in trusted, credible places across the web — not just your own website?
- Do you have the authority to clearly demonstrate expertise in your topic area?
- Can AI systems understand and connect your content from one place to another?
AI does not just crawl your site. It tries to understand it. Where content lives on your page matters. How it is structured matters. How it connects to other content matters. Good indexability means a better chance of being surfaced in AI prompt citations.
For those familiar with Google’s EEAT framework — this will feel familiar. The principles translate. The difference is that it now extends beyond your website to everywhere your brand exists online.
4. An Old Playbook, Rebuilt for AI
Schema Markup
Schema markup is a 10 to 20-year-old strategy that enterprise solutions have used for years. Tools like Yoast have been adding basic schema to sites automatically for a long time.
What is evolving is how LLMs and search engines are using schema to build content maps. It does not guarantee better rankings, but it improves machine readability. If you are already using Yoast, go deeper. Learn how to customize your schema using the Schema.org validator and Google’s Rich Results Test — use both together, as they operate independently and each catches different issues.
The LLMs.txt File
Search engines use a robots.txt file. There is now an experimental equivalent built specifically for AI systems — called an LLMs.txt file.
A few important caveats: it is not an official web standard, and there is no confirmed documentation from any AI provider that they actively use it. However, it is low effort, low risk, and aligns with broader machine readability principles. If Yoast has tested and rolled it out as a live plugin feature, it is safe to implement. It may not do measurable good yet — but it will not do harm.
Think of it as a structured summary layer. Experimental, but directionally correct.
FAQs and Tables of Contents
FAQs are one of the highest-leverage, lowest-cost moves you can make right now. They are a powerful schema type that allow you to answer the questions your audience is actually asking.
The recommendation: FAQs on every page. Not just the homepage. Not just service pages. Old blog posts, condition pages, everything. Written in a conversational tone that mirrors how your audience naturally asks questions. Internally linked throughout the site.
For long-form articles, a table of contents with jump links to each section is equally important. It increases structured data on the page, supports both SEO and AEO, and together with FAQs helps form the broader GEO narrative — where your brand protection lives.
5. Tools to Start With
For Prompt and Keyword Research
- AnswerThePublic.com — Good starting point for discovering what prompts people are using. Owned by Neil Patel, integrated into Ubersuggest.
- Ubersuggest — Accessible and useful for both keyword and prompt research.
- SEMrush — Deeper competitive research, actively evolving in the AEO space.
- Search Atlas — Emerging as a strong AEO-specific tool. Started as a content tool rather than an analytics tool. Features include prompt citation tracking month over month, internal linking improvements, and content rewrite suggestions. Speaker’s recommendation, not a paid endorsement.
- Manual research — Do not overlook this. Go into LLMs yourself. Ask questions as a user. Read the People Also Ask sections on Google. These are early signals of how your audience is actually searching.
For Tracking
- Is your brand showing up in People Also Ask and Things to Know on Google?
- Is your site being cited in AI-generated answers?
- Are brand mentions accurate — and are they saying what you want them to say?
GA4 can track AI referral traffic with the right filters. A referral source filter by domain is a straightforward starting point to see traffic arriving from ChatGPT or Perplexity.
6. Tactical Steps You Can Take Now
- Enable the LLMs.txt file through Yoast or manually via llmstxt.org.
- Add a table of contents with anchor links to every long-form article.
- Add FAQ sections to every page — old content included.
- Internally link your FAQs to relevant pages throughout the site.
- Run prompt research using Ubersuggest or Search Atlas.
- Rewrite key page copy to front-load the most important information. Ask yourself: what do the first 100 words of every page actually say? This applies to your website, your LinkedIn profile, your social bios — everything is now crawlable.
- Audit your schema. If Yoast is not giving you enough control, explore custom schema. Use the Schema.org validator and Google’s Rich Results Test together.
7. Brand Integrity in the Age of AI
AI is going to talk about your clients. The question is who taught it what to say.
Your LinkedIn, Facebook, YouTube, website, Substack — all of it needs to be consistent. Not identical. You can adapt the message to fit the channel. But the core narrative needs to be the same across the entire data sphere.
Narrative control is AEO. If you are not answering the questions, something else will. Answer them first. Make sure your owned content reflects the story you want told. Updates and consistent messaging across every platform and listing management service are not optional anymore — they are brand protection.
8. The Mindset Shift
For anyone who went through the SEO adoption cycle in the 2010s — this is that again. We still need great content. We still need structured data. We still need EEAT.
What has changed is who is reading it. AI reads differently than search engines do. Both are trying to present information to human users. We are now writing for robots to give to humans — and we need to understand that middleman and write accordingly.
We are writing for AI as well as humans. That is a weird thing to sit with. But it is the reality of search in 2026 — and the PR professionals who internalize it earliest will have the clearest path to visibility.
