Keyword Research for AEO: Find the Questions AI Search Engines Answer

Traditional keyword research is not enough anymore. When 31.3% of the US population uses AI-powered search tools like ChatGPT, Perplexity, and Google AI Overviews in 2026 (EMARKETER), the question is no longer "what keyword should I rank for?" — it is "what question will the AI be asked, and can my content answer it authoritatively?" Keyword research for AEO requires a fundamentally different approach: identifying the questions your target audience asks AI engines, mapping those questions to content gaps, and creating structured answers that AI systems can extract and cite. This guide walks you through the complete process, from research tools to content mapping to implementation for businesses in South Florida and beyond.

Why Traditional Keyword Research Falls Short for AEO

Traditional SEO keyword research focuses on search volume, keyword difficulty, and commercial intent — the mechanics of ranking a page for a query. AEO keyword research focuses on something different: the exact phrasing of questions that AI engines receive, so your content can be structured as a direct answer to those questions.

The Three Core Differences

Dimension	Traditional SEO Keywords	AEO Question Keywords
Query format	"best web design agency South Florida"	"What is the best web design agency in South Florida for small businesses?"
Primary metric	Monthly search volume	Question frequency + AI citation potential
Content goal	Rank page in results list	Become the source cited in AI answer
Content structure	Keyword in title, URL, headings	Question as heading + direct answer in first sentence
Success measure	Page position, clicks	AI Share of Voice, citation rate

The most important shift is in query format. AI engines receive natural language questions, not clipped keyword strings. Your keyword research must surface the full question forms — the way a person would actually type or speak a query — not just the topical keywords beneath them.

The Four Types of Questions AI Engines Prioritize

Not all questions have equal AEO potential. AI engines are particularly likely to seek cited sources for four question types:

1. Definitional Questions (What is / What does)

Questions asking for definitions or explanations of concepts are among the most common AI queries — and the easiest to optimize for. "What is AEO?" "What does Core Web Vitals mean?" "What is a landing page?" Clear definition-style answers with schema markup earn consistent citations. Your content should open each definitional section with a one-sentence definition, then expand with context.

2. How-To Questions (How do I / How to)

How-to questions map to HowTo schema and perform exceptionally well in AI citations. "How do I improve my Google Ads Quality Score?" "How do I set up a CMS in Webflow?" These questions benefit from numbered step structures, because AI engines can extract individual steps and present them as structured guidance. For South Florida service businesses, how-to content about local processes ("How do I get a business license in Broward County?") earns both local AEO citations and featured snippet placements.

3. Comparison Questions (Which is better / vs)

Comparison questions are high-intent queries where users are close to a decision. "Google Ads vs Meta Ads: which is better for lead generation?" "React vs Next.js: which should I use?" These require structured comparison content — typically a table or pros/cons list — that AI engines can easily extract and present. Brands that own comparison queries in their category can intercept buyers at critical decision points.

4. Best-Of Questions (What is the best / Top)

Best-of queries are high-commercial-intent questions where AI engines are often cautious about single-source citations. The way to win these queries is not to self-promote, but to provide genuinely useful criteria-based analysis. "What makes the best web design agency for a South Florida restaurant?" answered with specific evaluation criteria, real factors to consider, and transparent reasoning earns more AI citations than a list that simply names yourself at the top.

Tools for AEO Question Keyword Research

The best AEO keyword research uses a combination of purpose-built question tools, traditional SEO platforms, and direct AI query testing.

AlsoAsked

AlsoAsked maps the hierarchical relationships between questions — showing you the tree of follow-up questions that users ask after each initial query. Enter a seed topic ("Webflow SEO") and it returns a branching tree of related questions people ask in sequence. This is invaluable for building content clusters: the root question becomes your pillar page, and each branch question becomes a supporting article.

AnswerThePublic

AnswerThePublic visualizes all the question variations around a keyword, organized by question word (what, why, how, when, where, which). It pulls from Google's autocomplete and related searches, surfacing questions people are actively asking. For a digital marketing agency in Miami-Dade, entering "Google Ads" surfaces questions like "how much should I spend on Google Ads for a small business?" and "why are my Google Ads not converting?" — both excellent AEO content targets.

Google People Also Ask (PAA)

The "People Also Ask" accordion in Google search results is one of the most reliable signals of what AI engines are answering. Enter any topic query and review all the PAA questions that appear — these are questions Google's AI has already determined users want answered. Clicking each question expands it and reveals more related questions, creating a deep tree of AEO content opportunities.

Google Search Console

Your existing Search Console data reveals which question-format queries are already driving impressions to your site but not clicks. Filter queries that contain "how," "what," "why," "best," or "which" — these are your active question keyword opportunities where you are already visible but not capturing citations.

Direct AI Testing

The most direct research method is simply asking AI engines the questions your customers would ask. Open ChatGPT, Perplexity, and Google AI and enter 20-30 queries relevant to your business. Note: which queries return cited sources? Which return unsourced answers (indicating a gap)? Which cite competitors? This direct testing maps your AEO competitive landscape more accurately than any third-party tool.

Semrush and Ahrefs Question Filters

Both Semrush and Ahrefs include question-format keyword filters in their keyword research tools. In Semrush's Keyword Magic Tool, filter by "Questions" to surface interrogative variations of any seed keyword. In Ahrefs, use the "Questions" tab in Keywords Explorer. These tools add volume and difficulty data to question keywords, helping you prioritize by both AI citation potential and search traffic opportunity.

How to Map Questions to Content for AEO

Once you have a list of AEO question keywords, the next step is mapping them to a content structure that maximizes citation potential.

The Pillar-Cluster Content Map

Organize your questions into topic clusters. Each cluster has one primary question that becomes the pillar page, and 5-10 secondary questions that become supporting articles or FAQ entries.

Example cluster for a South Florida web design agency:

• Pillar: "What does a web design agency do for small businesses in South Florida?"
• Cluster articles: "How much does a business website cost in South Florida?", "What is the difference between Webflow and WordPress?", "How long does it take to build a website?", "What is responsive web design?", "Why is my website not showing up on Google?"
• FAQ entries (on pillar page): "Do I need a web designer if I use Squarespace?", "How often should I update my business website?", "What is a landing page and do I need one?"

Intent-to-Format Mapping

Different question types require different content formats for optimal AI extraction:

Question Type	Optimal Content Format	Schema Type
What is / Definition	Definition paragraph + expanded explanation	Article schema with definition
How to / Process	Numbered steps with clear descriptions	HowTo schema
Why / Reason	Numbered reasons with evidence	Article schema
Which / Comparison	Comparison table + recommendation	Article schema
Best / Top-ranked	Criteria list + evaluation matrix	Article or ItemList schema
FAQ format	Q&A pairs with direct answers	FAQPage schema

Local AEO Keyword Research for South Florida Businesses

For businesses serving Broward, Miami-Dade, and Palm Beach counties, local question keywords represent a significant AEO opportunity — and one that national competitors are less equipped to capture.

Local Intent Questions

Local intent questions include geographic modifiers that direct AI systems to local sources: "What is the best digital marketing agency in Fort Lauderdale?" "How do I improve my Google Maps ranking in Miami?" "Are there Webflow agencies near me in South Florida?" These questions require content that explicitly mentions specific South Florida cities, counties, and neighborhoods — not just generic location mentions.

Building a Local AEO Keyword List

Start with your core service keywords and add local question modifiers:

• Core: "SEO" → Local AEO: "How does SEO work for a small business in Broward County?"
• Core: "Google Ads" → Local AEO: "How much does Google Ads cost for a small business in Miami?"
• Core: "web design" → Local AEO: "What should I look for in a web design company in South Florida?"
• Core: "digital marketing" → Local AEO: "What digital marketing strategies work best for local businesses in Palm Beach County?"

Local Authority Building for AEO

Local AEO questions are answered more reliably when your business has strong local authority signals: consistent citations in South Florida business directories (BizApps, Miami Chamber, Broward Chamber), mentions in local media (Sun Sentinel, Miami Herald, South Florida Business Journal), active participation in local professional communities (LinkedIn South Florida groups, BNI chapters), and Google Business Profile completeness and review volume.

Step-by-Step AEO Keyword Research Workflow

Here is a practical 5-step workflow for building your first AEO keyword strategy:

Step 1: Seed Topic Identification (30 minutes)

List the 5-7 core topics your business owns expertise in. For a South Florida digital marketing agency: SEO, AEO/GEO, Google Ads, web design, Webflow development, lead generation, Meta Ads. These are your research seed topics.

Step 2: Question Harvesting (2 hours)

For each seed topic, run research in: AlsoAsked (export the question tree), AnswerThePublic (export all question variations), Google PAA (manually expand 3-4 levels), and direct AI testing (run 5 queries per topic in ChatGPT and Perplexity). Collect all questions in a spreadsheet.

Step 3: Question Prioritization (1 hour)

Score each question on three criteria: AI Citation Potential (does testing show AI engines are currently citing sources for this query?), Search Volume (does Semrush or Ahrefs show any search volume?), and Business Relevance (would a user asking this question be likely to need your services?). Prioritize questions that score high on all three — these are your highest-value AEO targets.

Step 4: Content Gap Mapping (1 hour)

For each prioritized question, check: do you have existing content that answers it? If yes, does that content follow answer-first structure and include schema markup? If no, add it to your content creation roadmap. Mark questions where competitors are currently being cited — these are your priority gap-closing targets.

Step 5: Content Creation and Optimization (Ongoing)

Create or revise content to answer your prioritized questions using the formats mapped above. Implement FAQPage schema on all question-answer content. Add Article schema with author markup to all blog posts. Test your citation rates monthly and adjust your content based on what is and is not being cited.

Frequently Asked Questions

What is AEO keyword research?

AEO keyword research is the process of identifying the natural-language questions that users ask AI-powered search engines, so you can create structured content that AI systems will cite as the authoritative answer. It differs from traditional keyword research by focusing on question phrasing and answer structure rather than search volume and page rankings.

How do I find what questions ChatGPT is being asked about my industry?

The most direct method is to ask ChatGPT directly. Enter your core service areas as questions ("What should I know about hiring a web design agency in South Florida?") and note what follow-up questions it suggests. Also use AlsoAsked and AnswerThePublic to map question trees around your key topics. Google's People Also Ask boxes reveal questions Google AI is already answering in your space.

Should I use exact question phrasing as H2 headings?

Yes — using exact or near-exact question phrasing as H2 and H3 headings is one of the most impactful AEO content signals. It directly maps your heading to the query an AI engine receives, making it easy for the system to match your section to a user's question and extract your answer for citation.

How many questions should I target per content cluster?

A well-structured content cluster typically addresses 15-25 questions: one primary question for the pillar page, 5-8 secondary questions for supporting articles, and 5-10 FAQ entries on the pillar page itself. Starting with 10-15 questions per cluster is realistic for most businesses launching their first AEO strategy.

Conclusion

Effective keyword research for AEO starts with a mindset shift: your audience is no longer typing clipped keyword strings into a search box — they are asking full questions to AI assistants that then decide whose content to cite.
