From SEO to AEO: How AI Overviews Are Changing Google Search

Google Search is undergoing one of its biggest transformations in years. AI-generated answers are becoming an increasingly important part of how people discover information, research products and services, and make purchasing decisions online.

Google’s AI Overviews are no longer a niche search feature. Recent research indicates that AI Overviews now appear on roughly 48–50% of US Google Search queries, compared with approximately 6.5% in January 2025. This represents a dramatic increase in the role of AI-generated answers within the search experience.

For businesses, this shift means that ranking on the traditional search results page is no longer the only goal. Brands must also understand how to become visible and cited within AI-generated answers.

Google AI Overviews Are Reshaping Search Behavior

The growth of AI Overviews is not uniform across every type of search. Certain industries and search intents are significantly more likely to trigger an AI-generated answer.

Healthcare-related searches, for example, can trigger AI Overviews at particularly high rates, while education-related searches also show strong AI Overview presence. Entertainment-related searches generally have lower coverage.

Search intent also plays an important role. Question-based and long-tail searches are much more likely to generate AI Overviews than short, broad searches. Research indicates that approximately 60% of question-style queries can trigger an AI Overview, compared with around 8% of one- or two-word searches.

This highlights an important opportunity for businesses: users are increasingly asking Google complete questions, and AI systems are attempting to provide direct answers.

How AI Overviews Are Affecting Organic Traffic

The rise of AI-generated answers creates a new challenge for traditional SEO.

When an AI Overview appears at the top of a search results page, users may receive enough information to satisfy their query without clicking through to an organic result.

Studies have reported significant reductions in organic click-through rates when AI Overviews appear, with declines ranging from approximately 34% to 61% depending on the query and search environment.

This does not mean traditional SEO is becoming irrelevant. Search rankings, technical SEO, backlinks, content quality and domain authority remain important.

However, the definition of search visibility is expanding.

Businesses now need to compete for visibility both within traditional search results and inside AI-generated answers.

Why Being Cited in AI Overviews Matters

There is also an important opportunity for businesses that successfully become sources for AI-generated answers.

Research indicates that brands cited within AI Overviews can experience significantly higher levels of traffic and visibility compared with brands that are not cited.

Some studies have reported approximately 35% more organic clicks and 91% more paid clicks for brands that receive citations within AI-generated answers.

This changes the objective of search optimization.

Instead of focusing exclusively on:

“How do we rank #1?”

Businesses should increasingly ask:

“How do we become a trusted source that AI systems choose to cite?”

That is where Answer Engine Optimization comes into play.

What Is Answer Engine Optimization (AEO)?

Answer Engine Optimization, or AEO, is the practice of structuring and optimizing digital content so that it can be understood, selected and cited by AI-powered search and answer engines.

Traditional SEO primarily focuses on improving visibility within search engine results pages.

AEO goes a step further by optimizing content for AI-generated answers across platforms such as Google AI Overviews, ChatGPT, Google Gemini, Microsoft Copilot, Perplexity and other AI-powered search experiences.

The goal is not simply to rank.

The goal is to become a credible, relevant and citable source of information.

How AEO Helps Businesses Get Discovered by AI Search

A successful AEO strategy combines many of the principles of traditional SEO with content and technical signals that help AI systems understand a business and its expertise.

Structured Data and Schema Markup

Structured data helps search engines understand the meaning and relationships between different elements of a website.

Implementing relevant schema markup can help communicate information about businesses, organizations, products, services, articles, authors and other entities in a machine-readable format.

Question-Based Content

AI-powered search is heavily influenced by conversational and question-based queries.

Creating content that directly addresses the questions customers ask can improve the likelihood that a business's information becomes relevant to AI-generated responses.

Content should provide clear, concise answers while offering sufficient depth and supporting information.

Authoritative and Well-Supported Content

AI systems need reliable information when generating answers.

Businesses should therefore focus on publishing accurate, original and authoritative content supported by credible references and evidence where appropriate.

Demonstrating expertise, experience and authority can strengthen the overall trustworthiness of the content.

Topical Authority

A website should not rely on a few isolated articles to demonstrate expertise.

Publishing comprehensive content around a clearly defined subject helps establish topical authority and provides AI systems with a broader understanding of a business's expertise.

Instead of creating individual pages for unrelated keywords, businesses can build interconnected content ecosystems covering important topics, questions and subtopics.

Strong Entity Signals

AI systems increasingly understand businesses, people, organizations, products and locations as interconnected entities.

Consistent information across a company's website and reputable external sources can help strengthen these entity signals.

Business name, services, location, expertise and other important information should be presented consistently across relevant digital properties.

AEO Across the New AI Search Landscape

Search is no longer limited to Google's traditional blue-link results.

Users are increasingly interacting with AI-powered platforms to research information, compare businesses, evaluate products and find solutions.

A modern AEO strategy can therefore consider visibility across platforms including:

• Google AI Overviews

• ChatGPT

• Google Gemini

• Microsoft Copilot

• Perplexity

• Claude AI

• Meta AI

• You.com

Each platform may interpret and surface information differently, but the underlying principle remains the same: businesses need authoritative, structured and useful content that AI systems can understand and trust.

The Future of Search Is Moving Beyond Blue Links

The evolution of search does not mean SEO is disappearing.

Instead, SEO is expanding.

Businesses will continue to compete for traditional rankings, but they will also need to compete for visibility within AI-generated answers.

The brands that adapt early can position themselves not only as search results, but as trusted sources that AI systems use to answer customer questions.

The future of search is therefore moving from simply ranking for keywords to becoming a trusted answer and information source.

For businesses looking to remain visible in an AI-first search environment, the transition from SEO to AEO is no longer just an emerging trend — it is becoming an important part of modern digital marketing strategy.
