What is an answer engine?

An answer engine is an AI-powered system that directly answers questions in natural language, synthesizing information from multiple sources instead of returning a list of links like a traditional search engine. Examples of these answer engines include:

• • OpenAI’s ChatGPT
  • Google’s AI Overviews
  • Google’s Gemini
  • Microsoft’s Copilot
  • Anthropic’s Claude

Why does AEO matter for marketers now?

Experts predict zero-click search (i.e., just reading AI overviews to get answers without clicking through to a site) will continue to eat into organic search. Organizations that are not optimizing for answer engines will not be seen by much of their target audience.

According to the July 2025 Responsive research:

• • 80% of global B2B buyers in the tech industry use GenAI as much as traditional search when researching vendors.
  • 40% of all buyers use GenAI and traditional search options equally
  • 22% use GenAI more than traditional search when researching vendors.
  • Nearly half (47%) of B2B buyers use AI for market research and discovery, and 38% use it for vendor vetting and shortlisting.

Reliance on zero-click results is increasing.

2024 Bain survey found that about 80% of consumers now rely on "zero-click" results in at least 40% of their searches, reducing organic web traffic by an estimated 15% to 25%.

Organic click-throughs are dropping.

November 2025 study by Seer Interactive found that between June 2024 and September 2025, when AI overviews were present, organic click-through rate (CTR) dropped 61% and paid CTR dropped 68%.

AI engines are replacing traditional search results.

In October 2025, McKinsey predicted that 20-50% of traditional search traffic is at risk of being replaced by AI engines. Also, the number of Google searches that have AI summaries, currently at 50%, is expected to rise to more than 75% by 2028

AI is informing more buying decisions.

Gartner predicts that by 2028, 70% of B2B buying decisions will be significantly influenced by AI agents and AI-informed human buyers.

What is the difference between AEO and SEO?

AEO and SEO serve different but complementary purposes. SEO helps users find pages, while AEO helps AI engines use content to answer questions directly.

How do answer engines work, and how does AEO support them?

Answer engines combine retrieval systems, large language models (LLMs), and ranking logic to generate or select the best possible answer to a user’s question. Answer engines:

• • Interpret intent
  • Retrieve high-confidence content
  • Score retrieved content for reliability
  • Synthesize a concise answer using constrained LLMs that operate within strict boundaries defined by retrieved sources, rules, and confidence checks

AEO works by structuring content so that AI-powered answer engines can clearly understand, extract, and confidently present answers for dual audiences. This not only provides AI engines with a clear intent signal but also adds depth and credibility for human readers.

Who is AEO content written for?

Effective AEO content must work for humans and AI engines, using different signals within the same piece.

Answer engines need:

• • Direct answers
  • Structured headings
  • Consistent language
  • Authoritative signals

How can marketers get started with AEO?

Step zero—take a breath and remember that, while a lot of work, AEO is an incredible opportunity for early movers. Every organization will approach AEO from a different perspective, but the following considerations and getting-started tactics apply to all.

Inventory and rank existing content based on:

• • Current performance in search
  • Audience reach (e.g., general for multiple personas, technical, business, or specific influencer)
  • Position in buyer journey
  • AEO readiness
  • Effort to optimize for answer engines

Identify SMEs to:

• • Create content
  • Provide abstracts or outlines
  • Be interviewed for articles
  • Lend their name to ghostwritten articles

Develop a calendar for new AEO content that includes:

• • Asset information
  • Who will develop it
  • Reviewers
  • Date content final
  • Publish date

Engage the technical team

In addition to AEO assets, the backend must be optimized for answer engines. Be sure that your web teambunderstands the technical requirements for AEO content and is committed to implementing them.

How should organizations approach AEO execution?

Organizations often work with specialists to accelerate results and avoid common implementation mistakes.
