What Is AI Overview? A Complete Guide to How AI Summaries Impact SEO—and the Best Response Strategy

Have you recently noticed that when you search on Google, there’s an “auto-generated summary” that answers your question immediately—without you needing to click into any website? That’s Google AI Overview (AI summaries). Powered by generative AI, it quickly synthesizes information from multiple sources and delivers the most condensed key points. It’s convenient for users—but for SEO, it’s rewriting how traffic is distributed.

In this article, Codepulse will walk you through:

• How AI Overview works
• When AI Overview appears in search
• The real impact of AI summaries on website traffic
• How to get your website cited by AI—rather than replaced by it
• The current rollout status and how to plan ahead

1. What Is AI Overview, and Why Does It Matter for SEO?

AI Overview is Google’s generative AI feature that reorganizes content from multiple web pages and presents it directly in search results as a short answer or bullet-point summary.

In other words, before users even see your website link, they may first see an “answer Google compiled for them.”

This can lead to two possible outcomes for websites:

• Traffic drops: Users read the summary and leave.
• Visibility increases: If your content is cited, your brand can gain stronger exposure.

AI Overview is now fully supported in Taiwan, and since it began supporting Traditional Chinese in 2025, it’s showing up more and more often. As a result, content formatting, semantic structure, and “short-answer logic” have become far more important.

2. How Does AI Overview Generate Answers?

Google’s AI primarily synthesizes answers from three sources:

• Search Index: your website content that Google has indexed
• Semantic Parsing (NLP): whether your paragraphs can be “directly reused”
• Google’s own databases: official information and authoritative sources

AI tends to prioritize content that has:

• Clear paragraph structure
• Short answers and bullet-point takeaways
• High-authority sources
• Frequently updated, accurate pages

In short: the more “extractable” your content is, the more likely AI will cite it.

3. Which Keywords Are Most Likely to Trigger AI Overview?

Based on Codepulse’s real-world observations, AI Overview appears most often for searches that require “information organization” or “multi-source synthesis.” The following categories are most likely to trigger it:

1) Low-risk informational queries in YMYL topics (health, finance, legal)

Definitions, processes, and concept explanations are relatively “safe” for AI to summarize.
Examples: dental treatment workflows, loan methods, insurance coverage, types of investment risk.

2) How-to / procedural queries

Queries that involve steps, processes, application methods, and tutorials.

3) Complex questions that require synthesis

Comparisons, differences, pros/cons, and similar structures.

Key point: YMYL topics can trigger AI Overview, but only “low-risk” and “non-judgment-based” content is likely to be summarized and cited.

For example, Codepulse case studies include:

[Dental Clinic]

• Keyword: “conscientious dentist in Kaohsiung”
• Article: Looking for a Dentist in Kaohsiung? A Real Experience & Recommendation for a Conscientious Dental Clinic in Fengshan

[Investment]

• Keyword: P2P
• Article: What Is P2P? A Complete Timeline of the im.B Fraud Case — Pickback

 
[Insurance]

• Keyword: insurance transfer for car ownership change
• Article: How to Transfer Insurance When Transferring Car Ownership? Process & Fees (2025 Updated)

These topics all use clear “steps, definitions, and comparisons,” making them easy for AI to reorganize into summaries.

4. How AI Overview Appears—and When It’s Excluded

1) Placement in search results

AI Overview may appear:

• At the very top of the SERP
• In the middle
• Near the end of the AI summary section
• On mobile, placement adjusts based on screen size

Because it often appears near the top, it can significantly affect CTR (click-through rate). Recently, Codepulse has also noticed increasingly diverse layouts—suggesting Google is still testing which AI summary formats users prefer.

2) Query types that commonly trigger AI Overview

• What is… (definitions)
• How to… (steps)
• Why… (reasons)
• Product comparisons, specs, buying guides

3) Content that typically won’t appear in AI Overview

• Sensitive or high-risk medical advice (diagnosis, treatment decisions, medication guidance)
• Legal judgments or liability predictions (case outcomes, legal advice)
• Adult content
• Highly controversial or dangerous topics

That said, this type of content can still improve overall SEO performance through branding and strong professional E-E-A-T.

5. The Real SEO Impact of AI Overview

1) Content types most likely to lose traffic

• FAQ-style sites
• Pure informational blogs
• Content without strong brand differentiation

Because AI can show the answer directly, users may not click through.

2) Branded vs non-branded keywords

• Branded keywords (less impact): users specifically want you
• Non-branded keywords (more impact): easier to be replaced by summaries

3) Content that can actually gain traffic

• Bullet-point content
• Clear, summarizable steps
• High-authority content

If cited by AI, brand visibility can increase dramatically.

6. How to Increase Your Chances of Being Cited in AI Overview

This is the most important question in SEO right now. Below are Codepulse’s practical tactics and optimization methods.

1) Strengthen E-E-A-T (Experience, Expertise, Authority, Trust)

• Author credentials and background
• Cite reliable sources
• Update content regularly
• Clear section and paragraph structure

Especially for YMYL topics, this becomes a decisive factor.

2) Use structured data (Schema)

AI must understand your content, so Schema is important. Common structured data types include:

• FAQ Schema
• Article Schema
• Product Schema
• Local Business Schema

3) Provide “short answer + bullet takeaways”

AI loves content that includes:

• A clear conclusion in 1–2 sentences
• Bullet-point steps or comparisons
• One topic per paragraph

4) Use tables, comparison charts, and flow diagrams

AI often treats these as “highly structured content,” which makes them easier to cite.

5) Build topic clusters

This helps AI recognize your site as a “content hub” for the topic—making citations more likely.

7. AI Overview FAQ
