Keyword Research vs Question Research: What Works Better for AEO?

Keyword research has been the foundation of content strategy for two decades. It tells you what people type into Google — the phrases they use, the volume behind them, the competition for each. For traditional SEO, keyword research is non-negotiable.

For AEO, it's necessary but not sufficient. AI assistants respond to questions, not keywords. And the questions people ask AI assistants are structurally different from the keywords they type into Google.

How do keywords and questions differ in practice?

A shopper using Google might type: "ergonomic office chair 150kg". A shopper using ChatGPT might ask: "What's the best office chair for a heavier person who sits more than 8 hours a day with lower back problems?" The intent is identical. The formulation is completely different.

Keyword research would surface "ergonomic office chair 150kg" as a target phrase. Question research surfaces "best chair for heavier person + long sitting hours + back pain." Your product page needs to answer the question to win the AI recommendation — and no amount of keyword optimisation will get you there if your content doesn't address the specific use case.

How do you do effective question research for e-commerce?

Start with your product category and the five most common buyer problems: "I need [product type] that works for [specific use case]", "What [product type] is best if you have [constraint or requirement]?", "How does [your product type] handle [specific challenge]?"

Sources for real question data: People Also Ask on Google, Answer the Public, Reddit threads in relevant subreddits, Amazon Q&A sections on your own and competitor products, and direct customer support queries. These are the actual questions buyers ask — and they're your AEO content brief.

How does question research shape your content structure?

Once you have your question list, each question becomes either a FAQ item, a use-case paragraph, or an H2 section in your product content. A product description structured around five real buyer questions is almost automatically AEO-ready — because you're literally answering the questions AI assistants will receive from shoppers in your category.

Conclusion: do both, but question research drives AEO

Keyword research drives your SEO meta strategy. Question research drives your AEO content strategy. For most e-commerce brands, the questions are more specific and more numerous than the keywords — and answering them well is the highest-leverage AEO activity available.
